Done with 45 nm tech. Chips done with the same fabrication technology, with the same power envelope, can't be several times faster than other chips unless there is a big design flaw. We supposedly have here a WiiU console with a smaller power envelope than X360 and PS3, but several times faster... I'm sure that MS and Sony Engineers aren't retarded.

ummm...Microsoft and Sony don't make their chips. Nvidia and AMD do. I'm not sure who makes the Cell now though.

Making major changes to the chip architecture would affect system compatibility to some small degree. Its not so simple.
