When Intel does a die turn the speed range of the new processor sometimes
overlaps with the earlier die, so to distinguish the chips they use "2.0 GHz",
"2.0A GHz", "2.0B GHz", etc.  The functionality often is significantly
different, e.g. the P4 "1.8 GHz" has 256K cache, while the P4 "1.8A GHz" has
512K cache, so the "1.8A" benchmarks much better.
