If you're one of many who have been confused about the processor size of Sony's 40GB version of its PlayStation 3 game console, Sony Computer Entertainment head honcho Kazuo Hirai has some clarifications. Hirai confirmed that the new 40GB Sony PS3 uses a 65nm Cell Processor instead of the old 90nm versions.
Hirai also noted that while the Cell has been made smaller, the RSX graphics engine that powers the Sony PlayStation 3 remains at the 90nm measure. No performance differences are expected, except for power efficiency benefits for the 40GB version.
The SCE boss also addressed questions on the future of the 60GB and 20GB Sony PlayStation 3 models. He says that while both SKUs remain in stock, production has been halted for both.
Both the 20GB and the 60GB Sony PS3 are backwards compatible, meaning that they can run Sony PSX and PlayStation 2 titles. Hirai says that these two may be produced again in the future, but it depends on how the market reacts to the absence of backwards compatibility features.
