| D2K said: The Wii U has a Tri-Core PowerPC750 with 3MB of fast eDRAM, a Dual Core ARM Processor, and a dedicated sound processor. That's 3 CPUs, 6 overall cores. |
You can't sum all these cores like that! First, a sound processor isn't a core. It isn't a CPU. It doesn't have a conventional arithmetic unit or control unit. It's basically a audio decoding algorithm implemented in hardware to be faster. But it only does that, process audio. Nothing more. If you create a new audio codec today, it wouldn't be capable of decoding it. Second, the ARM cores are secondary just for background tasks. At least these one is a CPU, but as a ARM one it's weak as well. Even if you could use it for gaming, it would just add a massive (I mean massive, way worse than PS3 or even Sega Saturn) complication, without any benefit.
Besides all that, both PS4 and One have dedicated sound processors and ARM cores for background tasks. They have even more things, like a dedicated video decoder for streaming and dedicated hardware to decompress data. They actually have all that Wii U have and more. And about eDRAM, XB1 has 32 Mb of ESRAM and PS4 simply don't need this.
And don't afirm that PowerPC necessarily is better than x86. Apple changed to x86 because PowerPC was advancing slowly because only a few hardware solutions used it. And how we are comparing a tri-core 1.2GHz CPU with 2 octa-core 1.6+GHz CPUs, it's not even necessary to make other comparisons (like seeing that the AMD CPUs have way more cache and better branch prediction).
