A real system on a chip that does both cpu/gpu functions. MS has good relations with amd and ibm so it makes sense to continue that relationship for the next xbox.

I was thinking they could get the custom cpu/gpu from amd seeing as amd makes both. IBM has more experience with the power pc design that has worked so well for the 360. Just make sure it is cool enough.

I don't think there's a chance in hell that Sony won't use the CELL in the ps4. They have invested to much in it and it is optimized for parallelization, which means better performance from multicore devices. Which the ps4 will be, obviously. That is why we keep hearing "the power of the CELL".

Also, SOny will probably go with Nvidia once again, to ensure backwardscompatibility as well as having an edge over the competition. If the rumours are true, then Nvidia's next chipset (Kepler was it, no?) is a huge step forward and significantly more powerful than AMD's latest.

I don't see how they wouldn't have backwardscompatibility this time around. It would be a very bad choice. A really really really bad choice.

Looks like WiiU is on Power7 45 nm. I am hoping 8 cores. 32 threads.

Still rumored to have AMD 5000 series GPU. I am thinking with this new Xbox 3 rumor specs. That WiiU has either AMD 5700, or AMD 5800 series GPU. Highest hope I see is 5870 or 5850. Knowing Nintendo I am looking at 5830 with question in mind.

Xbox 3 is on Power7+ CPU 32 nm. I am hoping 8 cores and 32 threads.

Sources say AMD 6670 GPU, but I am thinking to be 6 times as powerful as Xbox 360 this is not the 6670 GPU, but more like the AMD 6850 GPU.

What's the CPU's difference? Well potentially higher clocks and slightly more capacity for embedded RAM I believe on the + specs. Details likely won't be set in stone for announcement until later.

I am hoping this means PS4 aims for GTX 560 if NVIDIA. Looking at OpenRL though makes me wonder if Raytracing + a Multicore high end PowerVR 6 chip might come about in 2012/2013 for PS4 use.

The wii won this Gen if were're talking sales
