From (the interviewer of this interview) Masakazu Honda's blog http://blogs.itmedia.co.jp/honda/2005/06/5_df9a.html (the picture of a PS3 devkit is at the middle, click it to enlarge) The devkit spec is: + a 2.4GHz Cell + an unreleased GPU with a slightly less clock speed than RSX, connected via PCI-E (4-lane, only for the test purpose) Currently the library can't split a job into threads automatically, but when you create threads you can choose one of 3 threading algorithms by which the system assigns threads on SPEs automatically. E3 press conference demo were actually running on this machine, which has the lower clockspeed and the lower bandwidth than the actual PS3 spec. Yay
