I'm not dracula, you can talk to me. Yes I'm serious.

Ok.
| PigPen said: 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. |
Please explain to everyone here how the Wii U's eDRAM makes every other [and much slower] components run as fast as that eDRAM.

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. |
Here's a good read:

There is no secret sauce in PS4, since they were never hiding anything, but Cerny said in that interiew they are expecting for devs to master using async compute somewhere mid-gen.
To simplify: if you read the interview carefully you will see that async compute translates into running lot of stuff that traditionally were run on CPU on GPU, at the same time as graphics, without taking any of processing power away from gfx tasks. And since PS4 has quite a few ACEs, I believe Anthony's comparison with CPUs.

The WiiU's ram is fast, but that doesn't change the fact it has very little of it. 2GB of DDR3 ram and twice the eDRAM of a console that came out 13 years ago is nothing to shout about. You need 16MB just for a 1080p framebuffer with double buffering. Yep. Half of the magical eDRAM instantly gone just showing a 1080p image. That's without AA like MSAA by the way, if you want your game to utilize that too then you're going to need to hand over more of that eDRAM. It sure is disappearing quickly, huh? We haven't even gotten to the actual game yet.
Cerny quite blankly stated they could have put eDRAM in the PS4 with slower GDDR5, but chose not to because the negatives out way the benefits. To quote him exactly:
"If we used eDRAM for this on-chip memory, we knew that bandwidths of as much as one terabyte per second — that’s a thousand gigabytes per second — would be achievable. The catch though, is that the on-chip memory would need to be very small, and each game team would need to develop special techniques in order to manage it."
Faster bandwidth levels are pretty pointless if no one is going to properly utilize it. Look at MK8. Nintendo themselves developed it, yet not even that appears to take much use of the benefits. 720p with no AA, sub standard texture filtering and relatively simplistic to render graphics. The only thing impressive amount its performance is the frame rate, and that can't really be credited to the eDRAM. You could also praise its sharp textures, but they are someone spoiled by the texture filter (which is why they looked so murky in the screenshots we had before launch).
The funny thing is even if you were right and the WiiU's ram was better (which, quite obviously, it's not), it wouldn't matter. The eDRAM doesn't stop it having an awful CPU and GPU :P
It's also pretty amusing you bring up GPGPU, since the PS4's is several time more capable than the WiiU's :P

Fairly dust and wishful dreaming.

So you want me to explain what Nintendo put in its box. Nobody knows the Wii U exact specs unlike the PS4 and XOne. There is still some that's a mystery. I'm talking about the very fast memory eDRAM that Nintendo has in its little black box.

So, in other words, you don't know what you're talking about.
Thank you for at least admitting it.

Why would they talk to you when they know they can't take you seriously?

You said a lot in there, but I'm going to jump on one. A awful CPU & GPU really. lol Nobody knows what's the Wii U GPU is. Up until now it's been all speculation. People buying Wii U's to crack them open to get little to no insight. It's also said it has more eDRAM, and no one knows what's it for. You're not completely wrong in your post though. You have some valid points.
