Soo ... what DOES it share with the 750?? Because at this point, you've pointed out the differences (45 nm design, supports SPP, uses EDRAM). Is Nintendo/IBM trolling those like you who are experts by using the name 750 when it shares almost nothing with the actual chip that came out in 2004?
Its completely binary compatable with the 750 cl (broadway) has the same.unique simd/fp architecture (paired singles), everything it needs.to be.fully bc compatable with the wii.
So it has a LOT in common. What we need to know is what is different, aside from obvious stuff, like unprecedented clock speed and smp, we know nothing, and it doesnt help that ibm stopped publically posting updates to the family in 2004.
