Yeah, it sounds like 28nm is definitely off the table now. It is crazy that we went this long without knowing that Shield TV caps its GPU to such an extent.

What about Google's Pixel C? I recall people reporting that the GPU barely throttles at all. Does it cap at an unexpectedly lower frequency too?

I heard it throttles to 400mhz though I don't have a pixel c to check myself.

Shield CPU clocks up to 2GHz fine, temps are between 40c to 45c. I have a infrared thermometer to check the outside case temperature and the little exhaust vent shows about 35c. The fan is dead silent, wouldn't be able to tell its on if you didn't check to feel a tiny bit of air blowing out of it hah!

No way to manually set the fan?

Bearing in mind that the July EG/DF article reported audible noise level with TX1...

The new HDR-capable, 4K streaming Shield TV that Nvidia just revealed at CES, it uses the same old Tegra X1 as the Shield TV from 2015.

It doesn't have Pascal-based Tegra Parker SoC, is that correct ?

Correct. It seems all they did was redesign some hardware and update the OS with new apps etc.

There is an option in the system menu to select performance or optimised setting. I have had it on performance mode, and when I stress test the CPU you can just about hear the fan, it's still very quiet. About the same as an idle-ish Macbook? Maybe performance mode is broken, hah.

Got the CPU to top out at 51c this time over a longer duration (5 minutes).

The 2015 shield tv is 4k and HDR capable as well.

Wasn't it speculated the Pixel C performed at around 840mhz for the GPU?

Pixel C runs the GPU at 850mhz, that is the unthrottled speed. I heard the throttled speed was 400mhz but I'm only adding that to the discussion as grey info, since I can't check it myself.

That's probably its maximum speed before thermal throttling, since it doesn't have a fan to cool the SoC.

Yeah its actually interesting with your information included. Gives a whole new view of the X1 really. Seems like its max Performance is not nearly as easy to hit as a lot were thinking.

Yeah I was trying to find more info but all I could find is someone complaining their pixel C was throttling down to 200mhz with some bug

So, does this mean that all of the benchmarks for Tegra Shield had the GPU running at around 315 GFLOPS max? Hmm.

And X1 is a mix of Option Maxwell and Option Pascal already. It never really mattered if it was pascal or maxwell, it only mattered how many SMs it had (both maxwell and pascal have the same) and which process node it used (which thanks to higher clocks than X1's 20nm without throttling, points to 16nm) so yes after dozens of pages of speculation about 16nm, 20nm, 28nm... Maxwell or Pascal. The best of those options are pretty much what we have and the specs have not changed one bit, they are still ~400gflops docked, 157gflops portable.

Don't know if this was talked about already, but one of SMD's latest tubes he says the Wii u actually has 350gflops and not 176gflops based on Eurogamer's article, http://www.eurogamer.net/articles/df-hardware-wii-u-graphics-power-finally-revealed

Wouldn't this put the switch speculated 400gflops close to Wii u's 350gflops? Therefore hardly a power boost? Or how does this work?

http://www.notebookcheck.net/Google-Pixel-C-Tablet-Review.158868.0.html

The Pixel C only warms up to 42.3 °C (108.14 °F) under maximum load, so the tablet never feels uncomfortable. The temperature is even clearly under the 30 °C (86 °F) mark while idling and we can only measure 27.9 °C (82.22 °F) on average.

pixel c throttles down to 400mhz and according to the above link the heat under max load is 42.3 C , then switch's 307.2mhz requires a fan for further cooling ?

People from Neogaf (FourthStorm specifically) actually analyzed Wii U's chipset to get that 175 GFLOPS number.

The Wii U is 176 gflops and how does this relate to the switch?
Did you guys bother reading the article at least? I don't know the maths here but SMD quoted Eurogamer's article, the one I linked, and he apparently did the maths and came up with 350gf instead of 176gf. I linked so someone knowledgeable can read and check this. If I knew how I'd have done it myself. And if it's really 350gf that puts it close to switch's speculated 400gf. And I'd like to know what that could mean power and performance wise. If anyone's going to shit post please don't bother. Someone knowledagble is welcome as I'm lacking in that department and I'm seeking it.

I'll quote this part from the article since no one bothers reading:

The consensus is Wii U is 176gflops, and this is also a fine example as to why flops shouldn't be the primary focus of discussion when talking about power of a console. Let's say the Wii U was 350gflops and Switch is 400gflops. Switch would still outperform the Wii U thanks to modern tech and compatibility with engines like Unreal Engine 4.

Here's the GAF thread that declared it to be 176gflops: http://www.neogaf.com/forum/showthread.php?t=511628

SMD also insisted the NX would be powered by AMD. Why are you giving him the time of day?

I could probably find a hobo on the street willing to tell you that it's 3000gf and it would be equally credible.

Excuse my ignorance in this subject, I've always read this and expected to take it at face value, but can someone show me real life examples/comparisons of 2 architectures having almost similar gf/tf with the lower one outperforming the other by miles because it's modern? I honestly and genuinely want to see this. And please no one respond with "it's not about power". I am very interested in tech talk but sometimes things like these I don't comprehend and would like to be enlightened.

You can feel the sadness and desperation in this thread suddenly disappearing with this 617 mhz news lol.
Or is it increasing?

Yeah, that's basically what I thought based on en-Hsun not hyping Pascal / Tegra Parker or an "X2" chip.



So then what was the point of the new Shield TV at all? Just a slimmer refresh?

Seems like its just about refreshing and trying to generate new 4k Hype.

Only the basic has a slimmer design. The Pro remains the same size as the original

Those are SuperMetalDave Flops, which you need to divide by 2 in order to compensate for all the hot air.

I would like ONE person to answer me seriously in here. How'd SMD use these numbers reported by Eurogamer:

The Wii U GPU core features 320 stream processors married up with 16 texture mapping units and featuring 8 ROPs

to reach 350gf?

Can someone who knows how these work show me how to calculate these?

EDIT: Thanks Nate for that thread. I'll look through it.

Would still like someone knowledgeable to show me simple calculations here.

My hobo will link you the article too if you buy him a beer.

Stay out of this discussion please.

So tell me if i've got this right...from this information..

Switch's GPU clock speed is actually 25% higher than the Shield's GPU in average use, contrary to previous information? And the misconception with the Shield was that it was running at Tegra X1's maximum clock potential(1ghz) as opposed to a lower clock speed?And the CPU is still half.

We know the clock speed: 550 MHz (I believe it was revealed by fail0verflow).
We count each clock twice because FMA (fuse multiply add: multiplication and addition in one step) is standard for GPUs.

320 (SPs) * 0.55 (GHz) * 2 (FMA) = 352. The problem is, there's most likely only 160 SPs, not 320. So, 176 GFLOPs.

A number of people have already answered you and you refuse to listen.

He pulled the math out of his ass. It's not difficult to understand. Or at least it shouldn't be, but wonders never cease.

I believe FourthStorm and z0m3le counted 20 alus in each of the 8 shader units instead of 40.

But he found something negative about Switch's performance, surely it must be true!


MDave is a hero and should get a medal or at least a cookie. This is the reason one should never set anything in stone before all the facts is known. It is really curious that no one thought of testing the Shield before MDave. I mean, isn't that a big part of the puzzle especially when comparing performance?

Thank you very much! So now I know how he's reached that number.

And checking Thraktor's thread, it seems Eurogamer's article is actually based on Thraktor's findings (?), which has 320:16:8. Then there's z0m3le's post from that thread:
8 shader units with 20 alus in each = 160ALUs @ 550mhz = 176GFLOPs + 24gflops+ of fixed function shaders

Update: sorry I wasn't here to post earlier, the 176gflops is probably correct, since this part does seem to be vliw based. However there is almost certainly at minimum Hollywood inside this die as well considering how Wii u handles backwards compatibility. @550mhz that would give Hollywood 24gflops. Fixed functions are far better at doing their job than programmable shaders, but can do little else. It is more capable than 360, but it is impossible to really compare beyond that.

update 2: the more I research AMD GPUs, there is the possibility that it is using more ALUs in each SPU, if it was based on VLIW5 R700, it would in fact be 176GFLOPs, but it if was based on something like Trinity's VLIW4, it would be 32 ALUs per SPU, leaving it with 282GFLOPs, and if it was based on VLIW5 still, but a custom chip, it would have 40 ALUs per SPU like some people are speculating, leaving it with 352GFLOPs. Hollywood is likely still along for the ride, and that leaves it with 24GFLOPs+ of fixed function shaders. Sorry for jumping the gun, I was unaware that VLIW5 had chips with 40 ALUs per SPU, 20 was the norm.

So I understand it's 20 vs 40 ALUs. 20 ALUs = 176GF and 40 ALUs = 352GF. Correct? Have we reached the 100% conclusion it's 20 ALUs?

I'm reading Thraktor's thread and still reading posts but it has 200+ pages and it's not easy going through all of them to reach the definite conclusion. Some here prefer to troll instead of pointing me to the proper answer. "SMD IS SHIT!!11!!1" is not an answer.

If I remember correctly, there was a dev kit leak sometime around the early part of the Wii U's life that pretty much solidified what the performance was. I'm a Wii U developer, but I'm under NDA and can't provide any information on this. However, do some searching and you should be able to find what you need. I can't remember who leaked it or when it was leaked exactly.
 
I do not think they will spend a minute even on how much power this thing has. My guess is its wiiu level or 360 level which is fine with me.


I Hope they show lots of cool games. I am looking forward to seeing more of controller and portable mode.

it's a long thread yea :) As I said it's been discussed to death.

If I remember correctly it was fourth storm who after thorough study of the die shots concluded beyond doubt its 176. Sorry I won't be the kind soul who bother to look it up.
