IBM 6x86MX PR300
Almost identical to thisIBM 6x86MX PR300 except for the clock frequency/FSB ratio. One runs at 233MHz/66FSB and the other at 225MHz/75FSB.
Since the IBM 6x86MX is essentially a Cyrix MII (same core, different name) they should perform equal to the Cyrix MII. See Cyrix MII 300GP/75 for benchmark results of both the 66MHz and 75MHz FSB version.
