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

[KimmoK]

Perhaps I'm mistaken, but to me it seems that the latest Freescale should be i7 caliber in performance?
The e6500 core scales up to 2.5Ghz, so I'm sure there will be models with fewer cores, but higher than 1.8Ghz clock.
Will this be the first time when PowerPC is going to use hyperthreading?

I think AOS will not change CPU architecture anytime soon:

"When it comes to leading edge PowerPC hardware their level of technical expertise is possibly unrivalled. As a result Varisys has contracted to work on several new development projects to improve and extend the AmigaOne product line". Adam Barnes, Varisys Technical Director said, "There is some exciting cutting edge PowerPC technology on the horizon and we are delighted to have the opportunity of bringing this to the AmigaOne platform." Varisys Managing Director Paul Gentle added, "We enjoyed working on the Nemo development which provided our first experience of the global Amiga community. We look forward to extending our relationship with the new projects and will do our best to "Keep this party going". Please refer to the Varisys and A-EON Technology website for future updates."

I dont know why we are even discussing 2.5 or 3 DMIPS here and there, geez

an i7 x86 has 53.3/MHZ or 177,730 MIPS at 3.33 GHz (6 core).

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.
