Tom Pabst of Tom's Hardware Guide (http://www.tomshardware.com) seems to do some pretty good benchmarks, generally using real-world applications (i.e. for benchmarking gaming performace, he actually uses several different popular games, not some meaningless "3D WinBench" scoring). From what I have seen of the benchmarks on Tom's site, the K6-2/3 is not all that great, in any situation. In my real-world experience, it seems to do just fine for everyday use on our Win95 boxen, but so do the PII and Celeron systems. I don't get much time to play a lot of games on our systems though. :-) In another RealWorld(TM) experience of mine, a K6-2 300 system I have (well, not at the moment) next to me does far fewer keys/sec for the RC5DES challenge than our PII-300 systems. According to the Distributed.Net web site, the RC5DES algorithms don't even use floating-point calculations, so the lower AMD FPU performance wouldn't even be a factor here. If anything I would have thought the AMD processors would have done better because they do integer calculations so well, but I guess not in this case. > But lately Intel has dropped their prices, and if I was to buy a new CPU > now, I would have to choose between PIII and K6-3 (They're pretty much > equally fast, AMD a bit faster in Q2 in windoze) Hmm... According to Tom's benchmarks, the AMD K6-3 450 did worse (almost 4 FPS) than a Celeron 400 in Quake 2 with a Riva TNT2 based card (TNT2 drivers are NOT 3DNow! optimized). In Quake2 using a VooDoo3 3500 card (whose drivers ARE 3DNow! optimized), the K6-3 450 fared much, much better than it did with the TNT2, but then only a couple of FPS higher than a Celeron 400. Now, if a Celeron or PII 400 which doesn't have anything but plain MMX can almost match a K6-3 450 with 3DNow! optimized software, imagine what a PIII could do with SSE-optimized software. Since the Celeron 400 is exactly half the cost of a K6-3 450 (according to Pricewatch, I just checked), I couldn't understand anyone buying an AMD processor for gaming or other multimedia stuff, and especially not FPU-intensive stuff. All this might change when the AMD K7 comes out, though. :-) Let's just hope the K7 lives up to what everybody has been hoping it will be. -- Chris Dillon - cdillon@wolves.k12.mo.us - cdillon@inter-linc.net FreeBSD: The fastest and most stable server OS on the planet.
