That would have the cache running at 1/2 of chip speed, or 212 mghz. The K6-2 runs it's cache at 100 mghz. Given that cache hits are about 98-99% with modern processors I would say that is the major advantage slot 1/slot a/socket 370 solutions have over socket 7 systems. Second....my major performance benchmark is 3d games....most of my Freebsd stuff runs on old 486s and pentium 100-166 type stuff. The windows machine gets the AGP video and P2/P3 type stuff...(games are what computers are for, after all. :) Third...I don't have alot of experience with the K6-2s other than seeing some guys run them as gaming machines. What do you mean when you say, "windows seemingly intentionally dogs with an AMD chip."???? Are you trying to say that an intel socket 7 processor runs windows better than an AMD one? I don't think intel has a socket 7 processor that is the equivalent of the K6-2. Are you trying to say that AMD K6-2s run slower than P2s under windows? If that is the case, I think you are seeing the results of a real world benchmark.
