What about an Amiga Cell machine?

I love the idea of multicore Cell Cpu but then.... it wouldn´t be a cell anymore, it would be a "tissue" CPU

Anyone have any idea how the Cell architecture differs from the PPC? Is it a completely different technology or is some of the PPC core retained?

And... for general-purpose computing how does it compare?

@ ne_one

According to Wikipedia:

"In a simple analysis the Cell processor can be split into four components: external input and output structures, the main processor called the Power Processing Element (PPE) (a two-way SMT multithreaded Power 970 architecture compliant core), eight fully-functional co-processors called the Synergystic Processing Elements or SPEs and a specialised high-bandwidth circular data bus connecting the PPE, input/output elements and the SPEs, called the Element Interconnect Bus or EIB."

The "problem" is that the main source of the power of a Cell processor are the SPEs, so the code has to be optimised for Cell's architecture to use its full potential.

Interesting... I vaguely remember someone mentioning the Friedens had a take on what would be involved to support the chip.

Could be interesting.

And what is the diference to Altivec unit, MMX, SSE..............? if your code is not optimised to use these "extra units" you don´t use the full potential
