Well, put it this way - would you send a shuttle up with a Pentium at the
helm? What, after the FDIV, F00F and permission-override bugs? FDIV caused
huge errors in floating point division, F00F meant the CPU would lock solid
no matter if it was in Protected Mode or Real Mode, permission override
meant that any program could get Ring Zero (highest permissions level,
equivalent to the Windows/Linux kernel during runtime) access. And go
totally ballistic with the hardware...
OTOH, I would send a Shuttle up with an AMD Am486 or K6 at the helm. Why?
Because I've never seen an AMD processor with any microcode or design
errors, period.

Later.
