[QUOTE="charizard1605"] Is this actually confirmed?

Well, Nintendo themselves say IBM PowerPC, and Wikipedia says it will be a Power7, and IBM Watson tweeted this which is Wikipedia's source. What do you think, is that enough? I think that gives it a +95% chance of it having PowerPC Power8.Would love it to be the 8 core model at 3.2Ghz but it's probably too expensive.
Current IBM POWER7 (8 cores) has a die size of 567 mm^2 on a 45 nm process with ~200 watts @ 3.8Ghz. Good luck in fitting 200 watts CPU into a small box.Nintendo need the 'good luck'! I imagine it will be a custom chip, and I doubt they'll go for 8 core. That's why I used my example of quad core before (not quoted, but its above).
IBM POWER7 (8 cores) 's die size is larger than the current AMD Radeon HD 7970's 352 mm^2 die size!!! I can't find the die size of the Power7 quad core. Even if the die size was 'large', could it be circumvented by using a custom chip?
Each POWER7 CPU core can issue 6 instructions per cycle while Xbox 360/PS3's PPE core can issue 2 instructions per cycle. Wikipedia says POWER7=4SMTs/Core, Xenon=2SMTs/core, I chose the POWER7 quad core meaning total 16 SMTs, whereby Xenon gets 6SMTs total. I can't see where you are getting this value of 6 instructions/cycle for the Power7 from?
PowerPC 970 (G5) CPU core can issue 5 instructions per cycle. No comment.
For games, a system with large CPU(e.g. Power7 Quad Core) with small GPU(e.g. Radeon HD 4770) would be destroyed by small CPU (e.g. AMD Steamroller Quad Core) with large GPU (e.g. Radeon HD 7850) combo (e.g. AMD Liverpool APU). Iabsolutely agree with you here. But if Nintendo put say, 32-64MB of eDRAM with whichever card, would it become quite a different animal? Plus, we don't officially know exactly which Radeon is going in there yet, how many streamers it has, GPU clock speed memory clock speed memory quantity, so many things we don't know. Sadly, we may never get to learn the specs.
Hi Ron. Some questions/comments for you. I know you're a real ninja on this subject.
All in all even if you have technical doubts, my quoted post has the sources which point to the usage of the Power7, or at least some varient of it.
