Rumor: Wii U final specs

So how about all the skeptics email them then?
Guys, that email was REAL. I just decided to email AMD on a whim and they sent me the EXACT same thing.
I'm speechless.

It means customized. They're not going to use an off the shelf part. Like has been hinted by some other users like BG and such it's supposed to have some fixed function aspects as well. That's not going to be part of the default chip, it probably also doesn't have the 1 gig of ram embeded on the chip board the way the default e67xx does.
*edit*
What ever chip they did base it on if its e67xx or not, it's going to be with some adjustments made, because its going to be a custom chip. It will not be an off the shelf part.

AMD has let that cat out
Guys, that email was REAL. I just decided to email AMD on a whim and they sent me the EXACT same thing.
The wording is weird.
"The E6760 is a specialized, embedded GPU that has been modified for the Wii U. It is a 67xx series GPU, but with adjustments made to optimize performance for the Wii U's functionality."
It makes it seem as though the E6760 itself is a customized/adjusted 67xx series GPU that has been made specifically for the Wii U's functionality, but I doubt that's true.
Yeah I guess that makes sense. I know they can't use actual DX11, but it kinda sounded strange to me how he sounded so unable to say yes or no. I guess he was just talking about it not actually being DX11 though.

Guys, that email was REAL. I just decided to email AMD on a whim and they sent me the EXACT same thing.
So, what we can safely guess:
CPU: 3 enhanced Broadway CPU Cores with increased cache
GPU: Modified E6760 of possibly 576 GLOPs, 480 shader processors, multiple display support (Wii U pad obviously), 128-bit memory interface.
RAM: 2GB of unknown type RAM (1GB is currently reserved for the OS) as well as 32MB of eDRAM.
"I was wondering if you could tell me if the Wii U console GPU was using the E6760, or something different?"
I thought I might as well be as direct as possible.

Well, colloquially, the GPGPU domain is considered everything that up until recently would run on CPUs, but today is being migrated to GPUs. Just because GPUs do these tasks better today. The fact a given 'GP' task historically started life on CPUs does not mean CPUs were well suited for it, or that the task was 'GP' as per today's understanding - CPUs are the default choice for a lot of tasks just due to historical reasons. I.e. until somebody discovers/designs a common part that does said task better.
Entire domains of tasks could benefit from a huge collection of ALUs, SIMD or otherwise.
I'm not sure I follow. What's the difference between tolerate and combat in this case?
You mean it won't be efficient. But whether it will struggle or not depends on what is the logical code under consideration and what is the GPU ISA.
I assume you mean lack of branch prediction hw, since GPUs have had flow control hw for some time now. It's not equivalent to CPU branch hw, but it could not be - branching in a massively parallel processor is an entirely different problem to branching in a single control flow.
Of course a CPU needs its 'private' SIMD units, if nothing else just for sporadic low-latency tasks. The tricky question, though, is: How much is enough? Are you sure you're spending your transistor budget wisely by placing those SIMD units with the CPU?
Surprisingly (or not) here's what Intel more or less did with Larrabee - they took some mature-design cores, slapped some advanced-design SIMD silicon on them (and by that I mean lots and lots of it), packed them all together on a coherent fat SMP infrastructure and gave that contraption to some very clever sw guys (game industry veterans, et al) to 'do something amazing with it'. We know how that ended - Larrabee could run its own debugger, but at performance/watt at typical GPU tasks it could not compete with actual GPUs. So a CPU with tons of SIMD resources is not the panacea some saw in it.
I started my career with software rasterizers, so I'm not cold to GP-friendly SIMD arrays myself. Heck I fancy them. I even might actually think they're the future of graphics. But fat SIMD arrays have their own specific needs, which may not align well with the needs of a common CPU design, BW being a very apparent discrepancy, another being the lack of massive hw schedulers in the CPU (hyperthreading is barely scratching the surface of GPU schedulers). By putting such SIMD resources too deep in the CPU domain you inadvertently subject them to the 'ways of the CPU' - sw scheduling, small mem pools of big BW and large pools of not-so-big, perhaps abysmal (for the SIMDs) BW.

Can't blame him when people are falling for obvious fakes like that email. Why would any customer service agent have any clue what is in the Wii U?
I don't know, but why would they even respond to begin with?
Or, maybe he is in CYA mode? We all have seen it before. Just deny (somewhat) what has been leaked to try and get back what was lost, but it is always too late.
I think that is the case here, as you can clearly see it by his 'attitude'.
Well some folks just like messing with others. That kind of information (GPU information) is just too classified and high level for customer reps to be privy to.

Yea they wouldn't,they would have a pre-design e-mail that a bot would send back.
Sounds good.
You'd think they would just say "We cannot comment on rumors and speculation."
Well like I said it might be a prank.

Like IBM twitter account?
It's all a balance I guess. If you have lots of GPGPU capacity, then aren't you sacrificing normal gpu capacity as its stealing space on the die. And what sort of thing do games programmers need to do that would benefit from GPGPU but wouldn't be suited for a multicore CPU to chew over?
I just think there is a risk that the system can become unbalanced with the GPU being asked to do too much
Why respond to emails then? It's odd that they can even give a response.

why is a GPU chip being treated like National Security?
everyone knows SONY/MS will be way beyond this GPU why not share the info?

Well, remember that we did have 'a guy' claim back in July that he was a former ATI employee, and most of what he claimed he knew about the Wii U came to pass as of Sept 13th. Interestingly enough, he also said that the GPU was a modified e6760.... so, there is that little nugget from July to go along with the two press releases relating to an e6760, and now we have this AMD "leak".
All added up, I think its pretty safe to say this just might be legit.
I am not sure If I would say that a modified 7000 series is way beyond a modified e6760.
I posted links to them a bit earlier, here you go.

e6760?
Great news. So its not lacking any gpu features of PS4/720 that could be of importance
Quite a nice bump over PS360 too.

Aren't you being a bit presumptuous? You do not know what GPU is in the Wii U or the PS4.
I was just about to suggest the same thing (wanted to post an hour ago but was too lazy). Someone ask AMD if the E2400 is in the WiiU and see what they say
Ok, for a moment i thought you were talking about those two emails, lol.
in that claim the guy said it's 824 Mhz. but AMD's site say e6760 is 800 Mhz.
This email thing is just too janky to put any belief into imo.
Could just be perception control. Look at how folks go on currently based on the notion of the base chip being old (R700 architecture). Now imagine if there was a hard line answer of what it was especially with MS and Sony poised to unleash AMD HD/77907850 based monsters in the next year or so.

True, just basing it off of rumors. That's all I can do, right?

We don't know any features of Durango/PS4 yet.
Stock vs Modified. I think that is a safe assumption.

Yeah, I mean... Pranksters aren't going to be all-pervasive throughout the company.

He also claimed that the amount of EDRAM on chip hadn't been finalized when he left, which I thought was quite a hilarious claim for a console that was 6 months from launch, i.e. Bullshit

someone is going to gut one open in a few months anyway
He's going by the rumored specs in the PS4/720.

Except for its more efficiant architecture (GCN) The 7000 series offers nothing that would make downports to a e6760 impossible!
EDIT: Yes the 7000 series rumor, like Meelow said

Maybe. Who really knows how long they may wait to finalize certain things? I don't think that point alone makes his comment BS. So far, his claims do not contradict anything yet. I wouldn't count it out as an option considering everything else.
