Check the GDC archives. 2014 or 15. I can't check right now.

Excellent 1 hour long presentation. "Parallelizing the Naughty Dog PS4 Engine Using Fibers".
32 core variants are for servers. At most you'll see 8 cores on the desktop.
source? amd has had 8 cores on desktop for quite a few years now. you don't think they will at least add 16 this time around?

yeah I'm not sure why they called them cores. most software isn't parallel because most people don't have a lot of cores on their processors. something has to come/go first.The more cores you add, the less clock you'll push at the same TDP. For the overwhelming majority of desktop software out there, including games, you want less cores with higher clock rather than a bunch of cores at lower clocks, with a minimum of at least 4 proper cores. Most software just isn't parallel enough to make use of those cores. So yeah, I think 8 cores is what you'd expect on a desktop Zen with the highest clocks they can push on the silicon.
Bulldozer's cores and modules were a mess, their 8 "cores" were not most people's definition of cores.
Zen will actually use full, proper cores and not the module shenanigans they used with Bulldozer. 8 core Zen would still be a step forward.
Unless they had an 8 module desktop CPU, I admittedly haven't followed their CPUs in years.
Yes, I decided to go with a PS4 for this year, but if AMD is competent enough for a properly priced mid-range Zen and their new GPU lineup, then I will go with them out of sheer respect. My FX-6300 and HD7770 is only good for LoL at this point, and damn do they heat up fast, even not in summer, and with non-stock coolers..
I got my buddy an FX-6300 for a new build this past summer. I told him straight up "If you want decent gaming performance you NEED a liquid cooler." Not bagging on AMD, but wow they really put out some heat.

Running my fx 6350 with a cheap 3rd party cooler (not liquid) @over 4ghz and i don´t have any heat issues. And it runs every game i want decently in 1080p.
@Zen and NX: I don´t believe Nintendo would need Zen, but i don´t think it would be too expensive or new for a 2017 console ( NX homeconsole isn´t likely to come out before 2017). I could see AMD wanting Zen in a new console and making a good price as far as licences go and that also wouldn´t be a 32 core monster. People say Zen would be too new für NX. Why is that? Zen is in the pipeline for some time now.
The horsepower has been there for better AI for ages. People who can write significantly better AI typically end up working in different industries, though. More cores isn't going to change something that isn't a hardware issue in the first place.

In basic, AMD can do 2 things during one clock, while intel can do 8 things during one clock

At that point when we factor mobo solid enough to survive 150W power drain for years you were probablyreally close in total price to cheapest i5+H81 mobo or in worst case i3.
CPU might be cheap but total setup to run highly overclocked FX is not.

I got the CPU and MOBO on a really good sale with 8GB of RAM for $150, including shipping. I had a PSU and AIO LQ lying around spare, so I didn't factor either of those in.
VR needs the horsepower that an x86 PC (or notebook) can provide and we plan to be a very big part of that with Radeon and AMD
For the first time since I have been at AMD, I can say with absolute confidence that AMD has the products and strategies to change any negative perceptions customers may have had
By the end of the year, AMD will have moved on, to both its Zen CPU core as well as the Polaris graphics architecture. We are far closer to Intel than ever before you always need a number two to keep them honest
They spent so much of their time chasing their tails on the failed APU venture. All of their stuff is so outdated and middling. When you're in that position and you're still second to market? The only thing that can save AMD is if Zen really is the second coming of Jesus (a.k.a Jim Keller).
As someone who's still chugging along with an FX-8350 and 8gb of DDR3 with a Raptor HDD, i'm really looking forward to my first big upgrade in a few years. Zen FX Cpu, 16gb DDR4, 1tb SSD.
They're just taking so damn long!
That "failed APU venture" got them into two consoles. And while the CPU cores in their APUs aren't the fastest, the most performance limiting factor in terms of game performance has been the lack of bandwidth, and that should be lifted if and when AMD releases an APU with HBM.
Intel already has 22 core server chips, and by the time 32 core Zen comes out no doubt they'll have at least the same amount.
Supposedly Zen is launching with only 8-core variants first, probably targeted for server applications. No one knows how yields will be but they might not have enough volume to sell to the end-user market right away.
Of course actual performance is still completely unknown at this time. It's pretty much a believe-it-when-I-see it scenario at this point, AMD has a long history of hyping up products which dramatically underperform. Their last CPU which actually performed in-line with hype was the Athlon 64/X2 back in 2003.
Not coincidentally, the last AMD CPU I owned was an Athlon 64 back when it was taking Pentium 4 out behind the woodshed and beating the living crap out of it. Then Core 2 Duo came out and I've only had Intel ever since.
Read the article I posted, if true it looks very promising.
The consumer FX processors we get first will be 8 and 6 core, no quad cores yet. IPC is at least Broadwell-level.
Good. I like all the buzz around Zen. AMD can do impressive things when they're not, erm, digging in the wrong direction.http://wccftech.com/amd-zen-competes-intel-performance-features-price-launching-2016/
I'm pretty excited for Zen, my next system build late this year or early next year will most likely have at least a 6-core/12 thread Zen FX CPU. Looks like its IPC will be somewhere between Broadwell and Skylake, but offering 8 cores for the price of a quad i5 of i7, finally making them competitive again. We haven't seen this since the Phenom II/pre-Sandy Bridge days.
Is largely wrong. While uop caches can help with branch mispredicitons indirectly, their main purpose is to help with decoding. What mainly helps with branch mispredictions is predictors and BTBs.The latency that results from branch mispredicts are quite significant. To combat this issue Intel introduced a micro-op cache with Sandy Bridge. It worked to considerably reduce mispredict penalties and it was the principle reason why Sandy Bridge had much better single threaded performance as opposed to Bulldozer. The latest Linux Kernal patch as well as a group of AMD patents indicate that the company has implemented a similar solution in Zen.

No chances for Jaguar size. Physically impossible with the high IPC and SMT.How big do you think is each core?
I hope it's not the tiny 3.1mm² Jaguar size, it would be nice for PS5X2 to have some CPU beef for once.
So only half the cores of a Nintendo 64? FFS AMD...
Actually, no, the cores were part of the design. The high frequency was due to low IPC vs Intel. They didn't want to run those frequencies/TDPs.
The old CPUs use a single floating point unit shared over 2 cores. Only integer units are assigned to each core. This was one of the major pitfalls that lead to your post.
If the just follow some basic outlines like Intel CPUs they should inherit a nice boost without too much work to get close to Intel.
Even if it just gets Intel to lower the price on their 6-8 core CPUs it'll be worth doing
I thought it was the opposite shared integer with their own fp units.
