pretty much. If you look at browser benchmarks like sunspider, phones and tablets are about 10 times slower than PCs.
Code has a lot to do with it as well though, the latest ios 5 update made a dramatic improvement.
I've just done this with a 9800GTX which was getting severe corruption before crashing. This was when doing anything with 3D (even Windows Aero) or video playback (like youtube)
It no longer has those problems, but it is however running games at half speed. Frame rate is literally half what it...
It's not entirely impossible that they could include an Xbox 360 CPU/GPU package onboard like Sony did with PS2 hardware built in original PS3s.
From what I understand, the 360 CPU/GPU is on one chip on the latest slim models. Actually, they might only need the CPU part if it's an AMD GPU...
AMD Fusion makes perfect sense for a new console. They only have to pay one license fee, cheaper to manufacture, it's a single platform that is designed to work efficiently instead of bringing an IBM CPU and AMD GPU together to work in harmony etc etc
Any competition for Unreal Engine 3 is a good thing IMO.
Crytek overpromised with Crysis 2, boo hoo. Still doesn't take away from the fact that CE3 is probably still by far the most cutting edge and powerful engine out there, although Frostbite is looking rather incredible too.
