>IBM Xenon 3.2Ghz CPU which is compatible with PowerPC.
You mean the X-Box CPU.This is simular to Cell.the PPC is high clocked, but give less performance /MHZ because its a in order design.benchmarks say the 3,2 GHZ give simular performance as a 1,6 GHZ Athlon.
So should faster as PA6t on single thread, have three full cores, so i think you are right, this CPU is the most powerfull PPC.
I see in wikipedia there is a 45 nm version(so its also modernest chip develop for low power), but there are no TDP Values see and more bad it cant buy in low quantities.
>Also when comparing 68060 to x86 remember Motorola was the first to make a clock >doubled CPU for desktop computers. A 50mhz 060 runs internally at 100mhz.
the 68060 was also a great design.A Intel CPU need on 486 or these days Pentium 1 need 10-20 clockcycles for multiplication the 68060 have a hardware mutliplicator that can multiply 32*32 -> 32 bit result in 2 clock cycles.
