Yes, we do knoq what is in it as that is not exactly hard to do. You buy one, strip it, then run the correct software on it. Job done. It's a 40nm gpu, which says enough, but when combined with benchmarks and power input, this gives you a perfectly good figure to work with.

Only that thing is still making people scratch their heads on GAF and Beyond3D because it's so customized that nobody's knows WTF is really going on as some devs are claiming that it has almost unlimited bandwidth for their needs on the device or that it's really efficient and the watt/performance ratio is stupid good without even really pushing the system yet. I myself am very puzzled by it because I did look at the Anandtech tear down and the real time teardown on twitch. If you look at the GPU die, the first reaction from me was literally "WTF?" because I've looked at plenty of AMD dies before, and the shit in the Wii U GPU is like ??? other than the obvious eDRAM areas and possible shader areas.


Yet anyone with the slightest bit of knowledge knows such claims are a) absurd b) impossible. The PS4s position and choice of RAM provides it with an insane bandwidth - one that will likely never be used. The WiiU's? Erm, how is that the case with theirs? The RAM is slow, small, and generic. It certainly will have a limited bandwidth. What is going on is the devs choice of words eg. "unlimited bandwidth for their needs" aka low spec games. If you are running pong, then hell, 2GB might as well be 2TB as it will make no difference. But if you are running a state of the art game such as Killzone:SF, then people would be saying otherwise. The fact that AMD have not commented on the gpu is a bad sign as all companies like to brag about their gear - look at how they have used the PS4 and xbox1 to push their JAg range of procs. But when it comes to the WiiU? Silence. That isn't a good sign and is most likely because the answer would be "we did the best for a low spec system".


uh, I've been talking about the Wii U now for awhile, it's not really about the PS4 right now in this discussion, I've already made it clear that it'd run shittier, we just don't know how much shittier, remember? The point is that the people actually working with the hardware are saying those things, so unless you are a dev and can provide me with actual benchmark numbers(which would be great, I'm dying to see it so I can actually estimate it's actual performance level and not second guess in a wide margin of a giant fucking circle.)

The majority of the bandwidth would be coming from the eDRAM BTW, DDR3 just has decent latency for fetching small data quickly and that performance will depend on how many cycles it takes to actually get to where it needs to be. Your comment about bandwidth with a low detail game also makes no sense, the bandwidth on the hardware itself will not change no matter what kind of game is being made, the more accurate estimate to what it might mean would be that with how much the dev thinks the GPU can handle, the bandwidth is plenty to work with is how I'm taking it. 1000TB/s bandwidth won't make a dick difference if the GPU itself can't handle the RAM anyways.

What I want are hard number answers, not opinions or bullshit, and more than anything else, if it has certain fixed functions, or what the fuck is hidden in those blocks in the GPU. The only things we know are "efficient" and "balanced." Nobody wants to share any numbers and I'm not a god damned Wii U dev so WTF Nintendo? AMD is not commenting on the GPU is because they are under NDA BTW, and who knows what the hell Nintendo is thinking? Nobody but the top brass in their company.

Shadow Fall is not state of the art BTW, there is no such game yet on the PS4 or Xbox One, they haven't pushed the hardware yet, it's just higher res and better lighting ATM if you remove your pony rainbow goggles, they are 7th gen games running on a decent PC rig right now with DX11 features turned on. I hope you are not satisfied with just that level of graphics this early in the generation at least. I'm counting on them to become much better so PC games can look even better.
