But can Shippy's insight on both console's processors finally answer the age-old debate about which console is actually more powerful?
"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."
What about the familiar refrain that the PS3's architecture is overcomplicated, challenging developers to program effectively? "The Cell architecture, from a software programming standpoint, is definitely a new paradigm," Shippy concedes.
"And I think what the game community would argue is that, since it is different, initially it is harder to program the Cell chip -- it's not a traditional multiprocessor environment," he says.
"The real hardcore coders would argue that, once you do understand it and can program to it, you absolutely get the most out of the hardware, and really write some fairly low-level code that's really high performance," he adds.
"I think some of the bigger game houses that will write more high-level code would really prefer an Xbox 360 -- right out of the chute, it's easier to write code for. I think you can really leverage the Cell hardware technology -- but it is harder to get your head around."
