I found Cyrix to be faster (300.000 k/s on a P166+), and AMD to be
somewhat slower (330.000 k/s on a K6-200), but still better then Intel.
An Intel Pentium on 100MHz did about 130.000 k/s. BTW The picture
changes drastically when you change from RC5 to DES, AMD is (was?) much
better at that. Operating systems may play a role in speed as well

750.000 on 450Mhz seems little to me - I'm getting that speed on an
Intel P2/266MHz.

PS. Note that all these speeds are from older (around v415) clients.
