Yep, this can be confusing because.... There's the AMD 5x86, Cyrix 586, NexGen Nx586, and of course the Pentium. The first two use a 486 style pinout, and the remaining 2 use their own pinouts. The AMD 5x86-133 is a bit faster than a Pentium 75 and a Cyrix 586-100 according to AMD's WWW page. (see http://www.amd.com/html/products/pcd/5x86/20030a.html) The Cyrix 586-120 gets close to the speed of a Pentium-90. The NexGen PF110 is about the speed of a 110Mhz Pentium (if one existed) and even besting out a Pentium 133 according to numbers from Winstone 95 for 32bit code. (see http://www2.shoppersnet.com/pf110stats.html for NexGen PF110 numbers) (see http://www2.shoppersnet.com/p133stats.html for Pentium 133 numbers) As for the NexGen 586 PF110, I tried it with FreeBSD 2.1R and it works great. No compatibility problems and is very fast. Info can be found at: AMD (www.amd.com) Cyrix (www.cyrix.com) Intel (www.intel.com) NexGen (www.nexgen.com and http://www2.shoppersnet.com) or newsgroups: comp.sys.ibm.pc.hardare.chips
