[QUOTE="gnutux"]You do realize that the CPU and GPU are direct upgrades from the Gamecube?!? They use the same instruction set, both Gekko and Broadway are PowerPC processors! gnutuxMrGrimFandango
Which would actually make the Wii REALLY easy for developers who dealt with the gamecube, they should almost already be hitting better looking games, doesnt seem to be the case.
Saying they are direct upgrades is a slight bit of a misnomer. True, both new chips are based on the old architecture, but in reality they are about as similar as a PII and a PIII. We don't know the specs of the CPU for sure, but if it is what people are saying, not only is it faster and more efficient, but it has more instructions. The same holds true for the GPU, only it is a bigger mystery. People have taken the Wii apart and taken the spreaders off the chips and found that the GPU in the Wii is too large for a simple overclock or redundancy. No one knows why this is. What can be said about the GPU is it is faster, supports more instructions, and has an enhanced TeV unit (Wii's version of shaders).
So many people wonder why third party games look like junk on the Wii. All you need to do is take a look at the Gamecube to understand why. The Gamecube was more or less the joke of the industry last generation, depite having some capable hardware. Very few third party publishers actually took their time to make a great looking game, but the ones that did made things of beauty. Anyway, because so few publishers got it right on the Gamecube, there is more of a learning curve with the Wii than one would expect. It also didn't help that most of the games you've seen have been built around modified Gamecube development kits (more memory, controller interface, NO CPU OR GPU UPGRADE) so you can't expect them to look better than anything the Gamecube can do for the moment.
