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)?
EDIT: Actually, ignore most of my post. Reading through this thread http://forum.beyond3d.com/showthread.php?t=34269 I'm not so sure about about the 750CL. Knock off half the 1MB cache of a 750GX and scale down to 90nm from 130nm and you have about 17-21mm^2. Also there is some confusion about what "20% less power means". Is it overall, average, over Gekko at the same clock speed, or on a MHz/W basis. Why everyone would say it's a 750CL if it isn't is my main problem with the GX theory.
