Said it before, the GFLOPs difference between the PS4 and XOne is comparable to 3-4 i7 cpu's. Once they start to get the hang of GPGPU that calculating power is going to allow for some big game differences, much more than a little higher resolution or a few more fps.

Why are you comparing a gpu to a cpu?

But it still has GDDR5 instead of eDRAM. This is to say Sony is trying to squeeze more power out of the PS4.

I'm not going to bother explaining how totally wrong this is again (you'd have thought the GC having 16MB of eDRAM while the WiiU only twice more with 32MB would have been proof enough for you), but the PS4 not having eDRAM was a choice specifically made by Sony, as stated by Cerny in the interview i previously linked you. It makes development far more complicated than it needs to be, which somewhat defeats the point in it.

I know I'm not wrong, you are. I've been ignoring you but now lets draw this out. The PS4 has GDDR5: 256-Bit Bus at 176GB a second. The large memory the Wii U has with eDRAM stomps it. The large memory aid in making inpressive graphics. The Wii U have not 4MB, 16MB but 32MB. You are talking at least 1Tb or 1000GB a second. The Wii U also has a GPGPU, and the GPU and CPU fit perfectly. The Wii U is a powerhouse.

Because the point of GPGPU is workloads that would otherwise be done on a CPU?

Which is great. It's what all the cool kids use.

Great for Sony that spent little to none on R&D, yes. For the Wii U, no. If that makes you cool then go on with your bad self. E3 gives the chance for the whole world to see it's power. You'll know that it can compete with the XOne and PS4 instead of the X360 and PS3.

Yes, but I don't see the point in this specific example. I guess you wanted to highlight the advantage over desktop CPUs but that point is pretty much moot since desktop gaming PCs will be using GPGPU in their GPU as well, which is also much more powerful and advanced.

Saying that the console's GPGPU is 3-4 times faster than a desktop CPU is like saying a plane is faster than a car. True but irrelevant to compare.
