This is slightly misleading. PII has 32K L1, 512K L2 (half speed) K6-3 has 64K L1, 256K L2 (full speed), and upto 2MB L3 (which with a 100 Mhz board is only about 8% faster than normal DIMM memory) However, the best Intel chips (PIIIs, not PIIs and not even counting Xeons where the PIII version can have 2MB of L2 cache) are a little faster than the best AMD (550 vs. 450). If you cannot afford the big Intel chips, then the K6-3 is probably a better buy than a PII. Even if you cannot get your code size under 298K (I am not sure how much of the L1 cache is dedicated to code on the AMD, probably 32K), the extra 200-225 Mhz on the L2 cache puts the AMD slightly faster than the same speed PII or PIII for chess programs (but the 500 PIII seems to outperform the 450 K6-3 even with the faster L2 cache in almost all of the tests that I have seen, but you have to pay to get the slight performance improvement).
