    But I don't know enough about VSX to make a proper comparison to AltiVec/VMX. Feanor?

    Difficult to say, no access to Power7 hardware, but from the _very_ few docs out there that I could find, it looks like a mix of Cell SPU and AltiVec. Some instructions are the same, others -esp the double fp or the decimal fp support- have no Altivec equivalents. No idea how it performs really. It probably is quite powerful, but there are virtually no benchmarks out there, IBM sure does a crap job of promoting its technologies.

    Update: this is the only doc I found with actual specs/performance info for VSX.
