I have nothing whatsover backwards and kindly don't make assumptions.
I stated that the "G5" - the PPC970 family - is a dual-core POWER4;
given that I was talking to someone who claims good knowledge of the
POWER processors but seems not to be so /au fait/ with PowerPC, I did
not see any necessity to spell out that POWER4 is a quad-core design.
PPC970 also adds Altivec-compatible SIMD instructions to POWER, but is
a highly capable 64-bit implementation of POWER. I'm not aware of much that modern PPC processers
can't do that POWER
can, other than things intended for the support of legacy IBM OSs such
as OS/400 or zOS.
z/OS is a "legacy" OS? Sure doesn't look that way to me.
Am I just blind today or something?
