[QUOTE="ronvalencia"][QUOTE="godzillavskong"] Sony has always been about custom cpus on their platform. Emotion engine, Cell, and even with their first entry into the market with the PSX they had a custom chip made by Ken Kutaragi. I'm sure spelled his name wrong though. The Emotion Engine in the PS3 was quite the performer and seemed like it would just keep improving, and improving, no matter how old it was. Great system. godzillavskong
CELL's SPE instruction set is based on PowerPC's VMX while ATI Xenos is not based on any known CPU instruction set. True. IBM developed both Microsofts and Sony's chips. It was thought that Sony's cpu was more capable then Microsoft's , but I'm not so sure of that anymore. Dave Shippy from IBM said they were pretty much the same. Then again I think he has to say that. Don't want to give the nod to either party, seeing as how you may lose a future business partner. It will be very interesting to see what route these two companies take with their new hardware. I hope they do make them extremely powerful. Just not extremely expensive. Dave Shippy made a comment on ATI's Xenos GPU.

"I'm going to have to answer with an 'it depends,'" laughs Shippy, after a pause. "Again, they're completely different models. So in the PS3, you've got this Cell chip which has massive parallel processing power, the PowerPC core, multiple SPU cores? it's got a GPU that is, in the model here, processing more in the Cell chip and less in the GPU. So that's one processing paradigm -- a heterogeneous paradigm."
"With the Xbox 360, you've got more of a traditional multi-core system, and you've got three PowerPC cores, each of them having dual threads -- so you've got six threads running there, at least in the CPU. Six threads in Xbox 360, and eight or nine threads in the PS3 -- but then you've got to factor in the GPU," Shippy explains. "The GPU is highly sophisticated in the Xbox 360."
He concludes: "At the end of the day, when you put them all together, depending on the software, I think they're pretty equal, even though they're completely different processing models."
