If I am wrong with something please correct me: The Wii fixed many problems that the gamecube had. The gamecube basically had an architecture than streamed everything at High Bandwidths because of th 1Tsram. I beleive though that in terms of cache the 1Tsram is extremely fast, but when used as main system memory it is outperformed buy the DDR ram in the original xbox. So that is really why the Wii has Gddr3 ram along with the 1tsram. The gamecube also had very little amount of ram compared to the Xbox. The Wii has more ram than the Xbox. The main difference though were how the Gpus performed shaders. Everywhere else they were on par. PC developers were used to the architecture of the Xbox, and could easily develop or port to it. It was basically a PC design with programmable shaders incorporated in the GPU. Now on the gamecube most developers thought it wasn't capable of the same shaders ignoring the TeV units that could produce them. This is basically what Happysquirrel mentioned above, but in easier to understand I guess. Now alot of developers that seem to have gotten use to the gamecube/Wii's architecture seem to be using the TeV more. The Wii basically doubled in raw power and clock speed, and there are probably some other upgrades that nobody found yet.(Nintendo has never released official specs, so we don't know too much about the Wii's hardware). Anyway the Wii is considerably more powerful than the Original Xbox, and we already see that in a few games. We also should see it in more games as time goes on.
