ARM vs. PPC (why continue the PPC path?)

I think those were MIPS per core.
So, i7 has about  8.8DMIPS per core?

Latest PPC designs have 6DMIPS per core and 12 cores (24 virtual cores). That's  130,000MIPS at 1.8Ghz for embedded use (2.5Ghz is the maximum clock rate -> 180,000MIPS or so with desktop caliber cooling?)

So, for performance, we "only" need SMP. :-(

The "problem" just seems to be that custom board are more expensive than mainstream boards.

AMD Llano's 400 stream processors can do 260,000 MIPS at 650Mhz (400 stream processors or 80 VLIW5 math processor array). K markings can overclocked the "Radeon HD cores" to 900Mhz.

Amiga was never about having the fastest CPU.  Amiga was a media PC and it had the advantage because of its custom chipset.  The Blitter was a proto-GPU.  Xbox 360 gets by on a 3-core PPC chip (I wonder if AROS could be made to run on it?) and is perfectly affordable.

Most of Xbox 360's heavy compute work is done on AMD Xenos GpGPU i.e. 48 SIMD math processor array.
