What's going on here? Same specs, same stepping, different TDP?

Probably refinement in the manufacturing process. As stated above 32nm is getting better and better.

What's going on here? Same specs, same stepping, different TDP?
It gives AMD flexibility. The 95W 8100, and 95W version of the 8120 are OEM specials, with the 125W 8120 being in wide availability. Outside of that, retail 95W 8120s are unicorns. Remains to be seen how they handle the 8140.


Wouldn't that mean a different stepping, though?
Not necessarily. It's largely in how they're binned.

For instance, you'll have a fully functioning 8-core that can't sustain the clocks needed to be a 95W 8120 (within a given voltage range), go as an 8100, 6xxx, or 4xxx (last two tend to have less than eight fully functioning cores).

Of course, the fab has played a large role in this. When you look at earlier samples, such as the ones in October reviews (manufactured months beforehand), ~50-60W+ difference in same model FX-8150s is not at all uncommon.


I've updated this post a few times.

AMD Trinity to be released May 15
http://www.sweclockers.com/nyhet/15255-amd-trinity-slapps-den-15-maj

WEB TRANSLATION said:
While Intel is occupying the higher performance classes AMD have a golden opportunity to attack the broad mid-range. Thanks to the well-oiled AMD graphics division can transfer the technology from discrete graphics processors to the same silicon as the traditional processor. Next up is the second generation A-series, known as the Trinity.

According to Sweclockers released the first processors based on Trinity May 15. They are starting with models of desktop computers and traditional laptop. Extra power-optimised variants for ultra-portable computers will take until June.

AMD Trinity features two to four processor cores with Bulldozer architecture, known as the Piledriver. Computational units are flanked by a new video part from generation DX11. According to AMD, the latter up to 56 percent higher performance than today's A-series.

AMD Trinity A8-4500M benchmarked in Folding
http://www.nordichardware.com/news/...-trinity-a8-4500m-benchmarked-in-folding.html

AMD's coming Trinity architecture is not far off, and has now been benchmarked in Folding with a mobile version: A8-4500M. The processor performance is actually better than expected, even though we are dealing with Piledriver cores.

Trinity is AMD's next generation APU, and comes with two Piledriver module, which results in a total of four processor cores. On the same silicon we find six VLIW4 clusters that build on the same architecture we find in the HD 6900 series, but many of the functions found in the new HD 7000 series has also made it. It is therefore expected by AMD to deliver on the integrated graphics and raise the bar even higher on that part.

Piledriver is an evolution of Bulldozer, which has made many question its processor performance, especially after the first benchmarks leaked. What we believe is a manufacturer has tested the mobile version of Trinity in Folding and the benchmark show promise. Something that speaks in AMD's favor is the high clock frequencies that can compensate for the lower performance-per-clock with the new architecture. The benchmarks are with two different systems and the results in Folding varies.
3nHSw.png
The two cores in a Piledriver module shares one floating point unit, so the boost there is relatively marginal. When it comes to integer performance the boost is nearly 40 percent, this is even though the new processors are specified to the same TDP. AMD told us we can expect up to 25 percent better processor performance with the same energy consumption over last generation, which matches the results above. The exact frequency of A8-4500M is uncertain at this time, but should be higher than 1,5 GHz found with A8-3500M.

AMD A6-4400M "Trinity" CPU sighted in HP laptop
http://www.cpu-world.com/news_2012/2012031601_AMD_A6-4400M_Trinity_CPU_sighted_in_HP_laptop.html

Later this year AMD is going to introduce "Trinity" processors, that utilize enhanced Bulldozer micro-architecture, codenamed "Piledriver". New processors will be released for both desktop and mobile markets, and we already know specifications of several desktop Trinity parts. First details of mobile Trinity CPUs were revealed in February, when Arctic announced MC101 HTPC. The Arctic MC101 system will come with quad-core A8-4500M and A10-4600M SKUs, which integrate HD 7640G and HD 7660G graphics. The frequencies of these quad-core CPUs were not disclosed. Third Trinity-based mobile microprocessor recently appeared in specifications of HP g4-2002ax and g4-2003ax notebooks. The new part has model number A6-4400M.
Based on high clock frequency, we suspect that the A6-4400M CPU will fit into 35 Watt thermal envelope. Other CPU features, such as the size of on-chip caches, are unknown.

AMD A10 Trinity APU first impression
http://tbreak.com/tech/2012/04/amd-a10-trinity-apu-first-impression/

The CPU and GPU combo we’ve all been waiting for.

The prototype laptop AMD had brought along with them had undisclosed specs, but they confirmed that it was running their top of the line A10 quad-core APU. This test unit specifically was running just the APU, there was no discrete graphics card within the laptop, ergo no CrossFire.

While they didn’t allow us to run the built-in benchmark on Dirt 3, we did get a chance to see the game running on the A10 APU with everything set on high and 2xMSAA. Check it out for yourself below.

Next up is a short demonstration of one of the new features AMD is implementing in the A10 APU. The AMD Steady Video technology is implemented at a hardware level on all Trinity based APUs, and one of the videos AMD demonstrated this image stabilization tech with was the extremely shaky Triple Tomcat Launch.

Trinity/Piledriver Performance
http://citavia.blog.de/2012/04/08/trinity-piledriver-performance-13460109/

Since February I'm regularly searching for appearances of new "family 21 model 16" BOINC results, which belong to AMD's Trinity APU. As I noticed, I'm not the only one doing that. ;-) Some early results of an engineering sample (ZD372058A4451_41/37/16_9901_800, which should clock at 3.7 GHz base and 4.1 GHz turbo clock according to the string) didn't look bad (one day it reached an integer score of over 13K on 64b linux). But to do some halfway accurate (or semiaccurate ;-)) analysis it is important to look at results achieved on the same OS (here: Win 7, 64 bit) and BOINC client version (6.12.34 here except for the ES, which run a 6.12.43 client).

The FP benchmark, which is a Whetstone benchmark, seems to run as a multithreaded benchmark according to "informal". At least it fills up all available cores while running. The integer benchmark, a good old Dhrystone benchmark, seems to be single threaded. Further it is important to know, that both benchmarks have a rather small memory footprint.

Since we don't know the exact clock frequencies of the benchmark runs, it is difficult to find the correct value for calculating per GHz results. I estimated those based on turbo clocks, which might lead to skewed results. At least in the case of comparing Trinity with its Piledriver cores to the FX models, I hope that rather similar turbo mode behaviour should reduce the error margin.

OK, here comes the table comparing several values I filtered out of my collected BOINC results to have OS and client version the same. As you can see, Piledriver w/o L3 cache seems to perform a bit better than BDver1 based FX models:

6295945_8174fda20c_llwaw3.png


Note: I used "Trinity vs. Bulldozer" to denote the difference between a L3-less Piledriver core and a Bulldozer core, which always had L3 available.

AMD Partners With PTC for Creo Parametric 2.0
http://www.anandtech.com/show/5747/amd-partners-with-ptc-for-creo-parametric-20

A few months ago during the Radeon HD 7970 launch we discussed how AMD would be revising their ISV relations. While their efforts with ISVs in the past few years had been decent, AMD had not put a lot of money into it, and what money they did have was controlled by a relatively large bureaucracy. Consequently their efforts paled in comparison to NVIDIA’s, who put in far more money and effort into the process.

As a result one of AMD’s reforms for 2012 was going to be that they were going to put more money into ISV relations in order to catch up to NVIDIA. And while our discussion with the 7970 last year focused on the gaming side of things, AMD is also throwing more money behind ISV relations for their professional graphics business. After hitting a significant low against NVIDIA’s Quadro lineup, AMD’s market share for professional graphics has rebounded based on the strength of their 40nm DX11 GPUs, and AMD is looking to keep that momentum going with these improved ISV relations.
With Creo Parametric 2.0, AMD and PTC have added support for a couple new features intended to significantly boost performance.



What is ISV (independent software vendor)?
http://searchitchannel.techtarget.com/definition/ISV
http://en.wikipedia.org/wiki/Independent_software_vendor
 
I've mentioned earlier the awful former management that lead to much of AMD's curent problems, and the big "Bulldozer 2" changes of Steamroller/Excavator, that will follow the tweaked Piledriver.

Here are some third party thoughts on that.


CZYOf.jpg


AMD to survive and thrive, still?
http://vr-zone.com/articles/amd-to-survive-and-thrive-still-/15564.html

With somewhat disappointing Bulldozer showing, and perceived wavering roadmap, there were comments in the industry circles how AMD will give up the main Intel competitor seat to someone like Qualcomm, or even cease to be in the CPU business altogether. This weeks' preview of the next-generation Fusion APU gave us a chance to mingle with AMD's top execs, see their new CEO and hear - unofficially, of course - what's the way forward.

The hot, dry Austin, in Texas, is the place where the top AMD management is, after all, so the chance of meeting high-level personnel at a press & analyst event is high. This time we're not talking more about Trinity yet, except that the thing does seem to perform well, and yes, there is a 17 W Ultrathin-class (read: UltraBook in Intel speak) Trinity with all the features enabled, i.e. two dual core modules and the full GPU - of course at a lower clock speed. That will make some interesting impact in that market later this spring...
The APUs aren't a problem either: the Trinity is expected to be sold out, whatever AMD can make - so, we come to the quantities question there. AMD gave assurances they can do many millions of Trinities this year, and, according to what was seen, the 'good enough' statement, as worn as it sounds, is right on target here.
Then we come to the CPUs, the real problem for years - I did overhear a discussion between the senior execs how did the whole thing turn out with the 'low IPC performance' Bulldozer instead of the other alternatives on the table, and how it will take some two years to completely turn around the switch to another much more IPC-efficient core architecture. The main culprit seems not to be the previous CEO, Dirk Meyer, but his predecessor Hector Ruiz, the 'Taco Bell' that replaced 'KFC goatee' Richard Sanders, the man who made AMD succesful.

They said that Sanders was so disappointed with Hector, saying once that 'he left Hector a roadmap to execute that anyone, absolutely anyone' would be able to get done. Of course, Hector did damage the company in many ways, which by itself is a separate story.
Talking about moving forward, the feel is that AMD is there to survive and thrive once again. Rather than repeating the bland statements of 'we don't want to compete in the high end, just on volume' which make no sense since a fabless company cannot compete on volumes against a competitor with seven large fabs at its disposal, this time there's clear indication that, after Piledriver, there will be substantial changes in both cores and system architecture from Steamroller onwards, that should help make AMD competitive closer to the top. I was told that delaying the socket migration beyond the AM3+, C32 and G34 to new socket is a good move, since AMD can design more aggressive, rather than stop gap, sockets for future platforms with better features like more memory and HyperTransport channels, as well as integrated PCIe v3, for greater future scalability. For the first time, some execs do acknowledge that Bulldozer approach may not have been the best one at the time, and things need to change. I was told that there is some good frequency scalability in the Piledriver core which should help gain some per-core performance ground.

So, in the near term, AMD will use APU to keep its presence in desktop and mobile market, and even low power 5 - 10 W part derivatives or Trinity may arrive for high-end HD++ tablets. The CPU core radical refresh is expected to complete within two years from now, along with brand new socket platforms, proving AMD a new base from which to attack the high end, again, just like in the good old Opteron/Althon 64 early times. The GPUs will continue to be the crown jewel of the company till then, though... expect new high end mobile HD7900 series later this month, and Sea Islands by yearend.
Keep in mind, by then Intel will have worked out most, if not all, of the kinks with Tri-Gate. Broadwell will already be online (big GPGPU iGP advancements and all) and Sky____ in the pipe.

AMD Confidently Shares a Preview of the Upcoming Trinity APU Experience
http://www.hardwarezone.com.sg/feat...ity+APU+Experience&utm_campaign=A1HWZhomepage

This week, renowned tech media around the world (including HardwareZone) were given intimate insights showcasing the capabilities of AMD's Trinity APU and the nuts and bolts of its design.
While all the technical details, features and performance results are under embargo for now and you’ll have to wait till 15th May for updates, what AMD has allowed to share at the moment is the experience of the AMD Trinity based notebook. Understanding that this class of products with the AMD Trinity APU are targeted at mainstream users, the company focused on improving end-user experience rather than focusing on raw benchmark numbers. A combination of the reasonably powerful graphics engine on the APU and accelerating applications enhanced with OpenCL API which AMD has been strongly pushing the software community in the background, they are able to improve what matters most for notebook users - the everyday tasks.
To showcase this, AMD setup a ‘blind’ challenge with systems hidden away and the tech journalists are only faced with identical monitors and a custom-built start button to get the comparisons started at the same time on both an AMD Trinity based notebook and a somewhat identically configured Intel notebook. With three different scenarios touching upon office productivity, home video playback and file compression, here are the results in brief from gathering feedback from all the journalists who participated:-
7GvgT.png
The results say it all that most participants (including ourselves) preferred the AMD Trinity system's experience. Now to put some perspective, these are findings from just a small sample of benchmarks used, of which most were running updated software benefiting from AMD's technologies or taking advantage of its built-in discrete-class graphics engine via the OpenCL API. While it may give AMD the upper hand, it also gives us an idea of the possibilities with the new AMD platform when the full set of features are exploited and put into good use.

So far it's looking positive as we found office productivity tasks loading and interacting a little faster and the same goes for file compression handling. For the video playback, it used a typical amateur home video clip and we noticed the AMD system applying post processing effects to improve color accuracy, remove noise and with AMD Steady Video technology, it even removed all the jerks and shakes normally associated with home videos. The Intel system on the other hand just played the video as-is. While the upcoming Intel Ivy Bridge processors could pose a tougher challenge, most are confident in AMD's lead where graphics are concerned because of their experience in better hardware and software.
While the Trinity APU is officially launching on the 15th May, AMD expects more notebook offerings to be available from June onwards. The desktop counterparts will come in later in the third quarter of the year.

MIPS: An Amazing Turnover

1.8 Million MIPS-powered Tablets Shipped to Date
http://vr-zone.com/articles/1.8-million-mips-powered-tablets-shipped-to-date/15604.html

During a panel with senior executives from Linley Group, Intel and Qualcomm, Amit Rohatagi, Principal Architect for MIPS Technologies detailed the mobile strategy of its company and the effects of collaboration with Chinese Ingenic Semiconductor. Ingenic was founded in 2007 and until today, the company shipped over 30 million CPUs. Ingenic is focusing on optimizing MIPS architecture and is currently working on new mobile chip based on MIPS64, a 64-bit architecture which debuted in 1991.

The growth of MIPS in tablet space is especially interesting. Since the announcement that Google Android 4.0 ICS is enabled to work on MIPS processors, MIPS started to grow in Mainland China like no tomorrow. Chinese Ainovo (products are sold under Ainol brand) was the first manufacturer to offer an 7" Android 4.0 ICS powered tablet for only $99, and after the company offered $79 and $119 parts, all tablets are continuously sold out. Ainol is producing as much tablets as they can handle, and the company is now starting to see competing companies launching their MIPS powered tablets.
The numbers are quite impressive - for a part that only hit mass production at the tail end of last year, Ingenic Semiconductor shipped 1.8 million chips for tablets. With the initial programme being deemed successful, the next step is to push for 10 million shipped units by the end of the year.

Given that even Philips launched a low-cost tablet product based on MIPS architecture (available in China only), time will tell when the world are going to take notice. Remember, just six months ago, nobody expected MIPS to emerge as a serious contender to ARM and x86.
In addition, ARM, among many others, are currently licensing IP from MIPS.





Suppose AMD Bought MIPS - MIPS’ largest customer is Broadcom
http://cloudcomputing.sys-con.com/node/2256201

Forbes, for one, its ears to the ground, is betting on the AMD rumor, pointing out that "MIPS has a chip that runs Android 4.0 ICS and consumes LESS power than competing ARM parts. Furthermore, that chip is built in old 65nm process versus power-saving 40nm and 28nm competitors."

Forbes thinks it would be a lot smarter for AMD to buy its own chipmaker for its new microserver acquisition than to license ARM as widely expected.

It might also replace some of the engineering talent AMD has lost.

MIPS is supposed to sample a two-core dingus that targets the ARM A9 later this year but again consumes less power and it's got 64-bit chip targeting the A15 in design. ARM is supposedly having trouble with 64-bits.

:lol

You know what, I kept thinking it's odd that first ATi then AMD bought those custom design knowledge with plenty of output (GameCube, Wii, Xbox360) without it publicly ever really being considered a notable part of their business compared to the PC/server business. It's only now with the strategy "change" that this ability went to the more public forefront.
 
Diablo 3 seem to love raw clockspeed. Whatever the case it's a game (the only one LOL) that makes the FX architecture look really good.

CPU.png


I guess when the game runs at 130 FPS on dual core CPU's though, you cant brag too much. Still, maybe just maybe more games can work well on the FX architecture going forward.

Techspot is claiming quarter 3 for production of desktop Piledriver. I was hoping for a lot sooner than that. "Production" means who even knows when they'll actually hit streets.

Going by the benchmarks the A10-4600M seems roughly equivalent to the i5 520M + Mobility 5650 in my laptop, just at a much lower TDP (35W vs 50-55W). Considering the only issues I have with the laptop are heat/noise and battery life, I'll probably be thinking about picking up a Trinity notebook.

Not sure if this is the best place to put this but simple question

I have a Phenom X4 820 and I am looking at upgrading my PC. I bought an AM3+ MB before Bulldozer was out. I'm trying to figure out if it's worth putting an FX-8150 in or am I unlikely to notice an increase in system/multitasking speed.
 
Desktop Trinity review is up on Tom's hardware:http://www.tomshardware.com/reviews/a10-5800k-a8-5600k-a6-5400k,3224.html

Course, I'm more interested in the Piledriver core IPC improvements. Tom's pegs them at 15% but only did two benches.

per%20core%20itunes.png


per%20core%203dsmax.png


Though the first bench is apparently a little bugged (later shows a 5600k beating the 5800k which is odd).

Anyways given AMD says Piledriver will scale over 4ghz http://www.engadget.com/2012/02/22/amd-piledriver-cores-will-employ-resonant-clock-mesh/

If you say top end Piledriver will be 4.2 ghz (could be even higher I suppose), and figure ~10% IPC improvement, so overall 22% faster, I compared a hypothetical 8150+22% faster to some of Tom's 3770k/8150 benches, came up with this
PCmark 7 overall suite score

3770k=5487
2550k=5079
8150=4189
8150x1.22=5111

PCmark 7 productivity suite score

3770k=5436
2550k=5103
8150=4105
8150x1.22=5008

Creativity suite score

3770k=5655
2550k=5138
8150=4792
8150x1.22=5846

i'd still worry about the chip most of all in gaming, the very thing we care most about. even a 22% speedup is still going to leave it looking a little sad next to intel in some gaming benchmarks. that said i even see a silver lining there, which is that in the future more games should start using more than 4 threads, so bd/piledrive/steamroller might start looking better and better at gaming over time if i'm right as games start using up to 8 threads.

Overall, unless I'm missing something obvious, my guess is the top Pile driver core is going to look pretty damn good next to Intel's best in a lot of benchmarks. Guess that's to be expected when you're expecting 20+% speedup for Piledriver while Ivy Bridge only sped up Sandy Bridge by 4%.

The bad part is all it likely means is AMD is going to charge 350+ for it, as opposed to 199 for 8150 right now...

Looks to me like "fixing" Bulldozer might have been easier than expected.

AMD's Jaguar packs four cores in one for mobile

AMD’s Jaguar Computing Core Revealed – FPUs Doubled
http://news.softpedia.com/news/AMD-s-Jaguar-Computing-Core-Revealed-FPUs-Doubled-288711.shtml



AMD let the new ‘Cat’ out of the bag with the Jaguar core - Hot Chips 2012: Bobcat MkII is a nice step forward
http://semiaccurate.com/2012/08/28/amd-let-the-new-cat-out-of-the-bag-with-the-jaguar-core/

At Hot Chips today, AMD is revealing some of the details about their new Jaguar core, the successor to Bobcat, the first of their smaller ‘Cat’ family of cores. Take four of these second generation low power cores, add a GPU, and off you go to power lower end laptops and higher end tablets.

Those among you that follow chips closely might realize that Jaguar is not the second iteration of the smaller ‘Cat’ family of CPUs and APUs, that was supposed to be the Witchita and Krishna twins. As SemiAccurate exclusively pointed out last November, those fraternal twins were canned for a number of reasons and the Jaguar cored Kabini was pulled in. Today AMD starts the long process of revealing this chips, but things like the speeds, die areas, and most of the uncore were not revealed. In fact, AMD didn’t even mention that it is a 28nm part.

So what did they talk about?
Sections:

- The Jaguar core; color coded by function and not to scale
- Pipes and more pipes, by the clock
- Bobcat vs Jaguar IPC and power gating
- The cores, new and old, portable and more portable
 
A bit of spring cleaning from over the last months...

AMD FX-Series “Vishera” Specifications Found

The FX-4320 is the entry-level CPU, insofar as a quad-core with a clock speed of 4.0 GHz (4.2 GHz Turbo Core) can be considered low-end. Its TDP (thermal design power) is of 95W and the cache memory (L3) is of 4 MB.

The “middle” CPU is called FX-6300 and has six cores. The base clock speed is 3.5 GHz while the Turbo Core frequency can go to 4.1 GHz. The TDP is 95W and the cache is 6 MB.

And, finally, we reach the flagship Vishera FX Piledriver Bulldozer, the 8-core FX-8350, with a stock speed of 4 GHz and a Turbo Core setting of 4.2 GHz.



As for Bulldozer 1: On the subject of a maturing 32nm process, reduced leakage, and improved overclocking on standard air/water I mentioned about the gen1 FX-8140, here are some CPU-Z caps. In case anyone thought it was imaginary.

Feist needs a cohort he can talk to in this thread. Or even a nemesis he can argue with.

It's an impressive collection of info you've created in this thread nonetheless.
 
Hilarious
ly sad
because it's true, and what lead to this post.

Strangely enough, this thread seems to be more useful for other sites that have referenced it, or reposted it outright, than GAF, apparently.

The Ivy Bridge launch thread I started had far more posts, and interest shown, and it's not a "lulz BD sux" thing, either. Participation was fairly low before BD's disappointing launch...



Shocker: Tom's writes decent pieces every now and then.

It really is.
And it's hard to get excited about any of it. :(

Hope AMD can do anything to compete with Intel in the enthusiast desktop market.

*And the CPU/GPU it looks to be ahead on which was a good focus a while ago. I'd easily recommend a system to some normal person that has that. Onboard video and even the HD2000 feels crummy.

Same, it's a little underwhelming.

Maybe they're ahead of the curve and expected more games and apps to be better threaded, but they aren't.

And seeing terms like 'refine' or 'improve' alongside things like 'surround' computing feels like they're going for the lower end embedded systems rather than power. Even in laptops Ivy bridge brings HD4000 which is a nice step up in power (and both intel and AMD integrated solutions are still lacking for all but the most casual gamer)

Don't want it in my next console particularly either..
 
Nice having you back here. =)

Intel's John Gustafson, known for Gustafson's Law, just joined AMD. It's clear that AMD is aware that it's the software that matters. I just wish existing software could always magically make use of current silicon improvements.
Thanks. With all the CPU/GPU talent they've lost to Samsung and Qualcomm, getting Gustafson and bringing Jim Keller back into the fold are both good moves.

Speaking of Samsung and Qualcomm and your mention of software, the HSA Foundation developments look promising on that end. HSA, AVX2, OpenCL, OpenGL, C++ AMP, others... good times.

I'll post an HSA Foundation summary when I have a moment.

What's weird is it seems like developers want to take advantage of the gpu muscle more than they want to optimize code for more cores.

I wish more articles would be worth wading through all the text. AMD's current relative strength is the total system efficiency (power per watt of CPU, GPU and NB) while keeping in mind, that it still runs on the bigger 32nm silicon. Most articles gloss over it and at best take AMD's TDP which is split in set groups (9, 17, 18, 25, 35, 45, 65, 80, 95, 100, 125W...) and reflect the worst case wastage allowed, not the actual average energy efficiency. I guess that particular approach fired back big time with the press simply comparing that with Intel's different use of TDP.

What's weird is it seems like developers want to take advantage of the gpu muscle more than they want to optimize code for more cores.

How is the developers' focus on graphics weird? That's more like a systemic plague. ;) Changing capabilities on the GPU side are accepted both more and for a longer time so the reluctance to make the comparably small step to make use of it also in GPGPU ways is naturally lower.

Some further AMD news:

With CodeXL AMD now offers development tools for both Windows and Linux for profiling CPU and GPU, debug GPU and analyze static OpenCL kernels.

For Windows AMD has an own app store called AMD AppZone which now has been extended with Android apps which run using the Blue Stacks Player, a (supposedly hardware accelerated) ARM emulator AMD invested in.

Just played a bit with CodeXl this week, cool program and good working for a beta.
Still miss some stats i couldn't find back that i had with sprofiler in visual studio with OpenCL.

So next week will try to find them if they are in that is.

What's weird is it seems like developers want to take advantage of the gpu muscle more than they want to optimize code for more cores.

Not sure i got this right but arent GPU not more bang/watt processors. Only got a brief introduction of the subject at current internship.
 
It was inevitable.

Not at all, really. Fine grained optimizations are cost-, and time-consuming. Most companies will do a cost-benefit, and opt to push products to market in different states of refinement. It's far easier to rely on brute force compute resources, as they always have. Now, with CPU and process mnfr advances increasingly coming at a premium, it's only natural to opt for GPGPU, and the various "easy" performance initiatives such as HSA, or AVX2.


Not sure i got this right but arent GPU not more bang/watt processors. Only got a brief introduction of the subject at current internship.
Yeah. GPUs are vastly more capable in most non-serialized tasks, and even the bad ones are still float point beasts. In FP64 Kaveri's GCN iGPU is a considerable step forward from Trinity's VLIW4. It's a nice GPGPU part, bandwidth allowing. I'm oversimplifying, but oddly enough, Intel and AMD's current approaches to iGPU performance are near inverses of their CPUs. Intel is largely throwing more execution resources at the top end Haswell, while AMD is going with higher "per-core" efficiency with Kaveri, in addition to more resources. Things begin to get truly interesting when the successors to Kaveri and Haswell arrive for 2014 and ~2015, respectively.

Wait, you were expecting tech sites to do proper performance-per-watt testing, along with real world usage in varying loads and tasks? Oh, you. People can hardly overclock correctly. Even the most respected sites can have glaring omissions, odd methodology, and lapses in basic level understanding of tech.

One of my favorites has to be a heavy FPU synthetic test (one which was more bound to the number of available units, rather than IPC or clock) where the reviewer was astonished that Llano came out ahead of Trinity, to the point where he re-tested to verify the results. *sigh

Another essentially implied the 100W A10-5800K would be twice as power hungry as a 55W Ivy i3 based solely on their rated TDPs. No, seriously. Now, I know I have a power consumption post in this thread, directly comparing TDPs of different CPUs, but it's assumed people would know that while there is some degree of correlation, TDP ≠ consumption. I simply used it as a reference point.

Also, you'd be surprised how many reviewers are unaware of AMD/ATi, Intel and Nvidia's different methods of arriving at wattage ratings, let alone how they've changed over the years (such as Intel's, for instance). AMD does take blame on this as they don't bin as aggressively as Intel (not that they have the luxury to...) leading to parts which are regularly overvolted (more draw than needed, and reviewer's can't be expected to undervolt them), particularly with the troubles on GloFo's 32nm.

Well, we'll see how good GloFo's 28nm bulk is, going forward with APUs, and how AMD's efforts transfer to TSMC's 28nm, in practice. I'm also hoping that AMD does the technically wise, if not financially "dumb," move of splitting from 28nm bulk on APUs in favor of ST's 28nm FD-SOI for CPUs. They'll eventually have to switch back to SOI, anyway. May as well get that going in the lead up to an FD-SOI+FinFET marriage at either 20nm, or 14nm at the latest/more realistically.



Review wise, some of the non-English sites are quite good.

Only a list? No insight? :)

Trinity looks like a great choice for consumer desktops. And will be a good step for people on a super budget and for advancing CPU/GPU performance for the masses.

Hopefully it gets Intel to exceed that GPU performance and include some damn unlocked CPUs under $230.

Vishera looks like a decent upgrade for the price and AMD looks to be executing pretty consistently these days as well. Hopefully they can keep the momentum.
