    Is anybody really doing this? :-) While the POWER7 "as is" is definitely not suited for our market(s) a trimmed down (features, power usage, cost) version surely could be. That's exactly what IBM did with the POWER4 after all.

    I take it you mean "G5", not "G6". And yes, the PPC970 aka G5 is a trimmed down POWER4.

    BigGun says that the Cell PPE architecture (while being way older, so it's probably the other way round) is related to the POWER6 architecture:

    Yes, exactly. But the real question is: Are IBM to target a large consumer market ever again with Power Architecture (not counting developments solely done for Microsoft or such)? :-)
    However, there is something going at IBM regarding alleged trimmed down POWER7 cores:


    I'm not sure if The Register is right though, because POWER7 is an out-of-order design while the A2 seems to be in-order. But the A2 core based PowerEN processor doesn't seem to be suited for our market(s) either, unfortunately.
