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.

176GB > 1000GB http://www.dualshockers.com/2013/06/29/mark-cerny-explains-how-the-ps4s-8-gb-gdrr5-ram-and-bus-work-and-why-they-were-chosen/ |
That doesn't make any sense, you have to read what he is saying carefully.

It makes perfect sense. 176GB is always available to use with the architecture they chose. In the other scenario they were thinking about , 1000GB would be achievable but only when it was in the small cache of eDRAM. Not only this, but each dev would create techinques specifically to take advantage of this and the GDDR5 would have to be a narrower 128bit bus thus halfving the main memory bandwidth to 88GB/sec.
