I was browsing through the latest news over at PS3Blog.co.za this morning and I saw that they had a posting about what the co-creator of the Cell CPU (David Shippy)Â had to say about his little baby compared to the (also IBM developed) Xbox 360 Xenon CPU.
When asked about which was more powerful he had this to say about the PS3’s Cell
â€œSo in the PS3, you’ve got this Cell chip which has massive parallel processing power, the PowerPC core, multiple SPU coresâ€¦ 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 â€” a heterogeneous paradigm.â€
and then when it came to the Xbox 360 he goes on to say
â€œyou’ve got more of a traditional multi-core system, and you’ve got three PowerPC cores, each of them having dual threads â€” 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 â€” but then you’ve got to factor in the GPU. The GPU is highly sophisticated in the XBox 360â€
and at the end of the day he actually thinks they are pretty equal.
This surprised me really as I was always under the impression that the Cell processor was far more powerful than the 360’s brain and it was simply the fact that the Cell was harder to develop for.
Maybe he was simply being diplomatic but from where I am sitting it seems like the 360’s simpler CPU is the more economically viable option.
