Thanks for explaining the PixelShader issue Entroper. The Wii is even more amazing than I thought :P.

As for the CPU discussion, the Wii's CPU is a PPC 750CL. It is not a 750GX since the GX is manufactured using 130nm not the 90nm the CL and Broadway use. The GX is also 52mm^2 which is much to large to be used as a base for the 19mm^2 Broadway (even accounting for using 90nm). Also, according to Wiki at least, the CL is just a lower power consuming CXe with various minor additions. This is IBM's datasheet for the CL http://www-01.ibm.com/chips/techlib/techlib.nsf/techdocs/2F33B5691BBB8769872571D10065F7D5/$file/750cldd2x_ds_v2.4_pub_29May2007.pdf
Broadway reportedly uses 20% less power than Gekko so the Broadway must be below the 733MHz speed since that one uses the same power are Gekko did. I know 729 isn't much below 733 but as it says in the notes, different voltages, bus speeds, and mulitpliers will cause different results. Considering the 1 GHz model uses 10.5 W I very much suspect Broadway's speed is below 733 MHz and not above it (I'd be willing to bet it's probably somewhere around 729Mhz).

Interestingly, Gekko was the same 43mm^2 as a standard 750CXe but Broadway is 18.9mm^2 which is somewhat larger than the standard 750CL's 15.9mm^2. I wonder what the extra 3mm^2 is used for, 256KB of cache, extra FPU's (I don't know if that would do any good), a second hidden core (I'm just kidding on that one)?


Oddly enough according to the CPU's markings the cpu uses a max 1.266 volts which would mean it fits in with the 1ghz model number.  I wonder if Nintendo bought 1ghz CPU's and locked them at 729.14mhz (since the cpu is capable of switching speeds through software).  Could this possibly mean that the Wii may have a mysterious 1ghz switch setting through software?  Hmmm...

Prepare for termination! It is the only logical thing to do, for I am only loyal to Megatron.
