| MDX said: So how do you explain the CPU of the Wii ? Is it a stock CPU or not? |
Nintendo and IBM collaborated on a low power SOI power PC processor, adapting and updating the existing technologies they had already made for the Gamecube, other than the OOE arch that was modified for the wii, interfacing instruction sets (for gekko) and the new cpu, it's more or less identical to IBM's 750CL.
It begs the question though, what exactly are you trying to prove by bringing up a powerPC cpu, built by IBM for Nintendo, it has nothing to do with the ARM11 cpu in the 3DS, while the Wii and WiiU CPU do ultilize an ARM part (pretty much stock ARM926 to be exact), it's used only for security layer and IO.
The cpu used in the Wii is a modified and downclocked 750CL, downclocked from it's stock 800mhz to 729mhz, too.
What you don't seem to understand is, approaching a manufaturer such as ARM or IBM for a custom processor doesn't get you a one of a kind powerhouse, it gets you a modified part at best, the modification comes in the form of shared R+D, We'll scratch your back if you scratch ours scenario, CPU manufacturer develops their CPU for sale, forks a modified version for the client, reducing overall development cost for the processor family.
And just to nip in the bud the idea of bringing up the WiiU cpu, it's essentially derived from the same 750CL platform, just updated for multi core and eDRAM cache and merged with the GPU to increase operational speed, as an individual part however the cpu is still downclocked over it's base platform counterpart, again to save on power consumption and heat, something Nintendo have always done.
