Even when the P4 is using RDRAM the AthlonXP 1900+ doesn't get outperformed at all. Look at www.tomshardware.com www.anandtech.com for example. Also I have some benchmarks (screenshots of my AthlonXP 1900+ @ 1.81GHz. Here's the link to the benchmarks... ftp://12.255.147.62/pub/overclockstuff/pics/newpc.zip Notice in the synthetic CPU benchmark (sisoftcpu.jpg) the Pentium 4 scores 3688 Mips and 1040 Mflops (straight FPU). Using SSE2 the P4 gets 2440 Mflops. The AthlonXP 1.81GHz gets 4977 Mips and 2493 Mflops (straight FPU). Good thing they didn't include an SSE/3DNow! fpu test for the AthlonXP :) Anyway those numbers show the AthlonXP being 190MHz slower yet 35% faster in MIPS and 140% faster in Mflops. Now, if you think the P4 is faster in games too.. absolutely wrong. Take Quake3 for example. These tests were done on EXACTLY configured systems. Only difference is the CPU, RAM, and Motherboard. Quake3 v1.30, demo 'four'. "Normal" Quality settings. Pentium4 2GHz - Leadtek Geforce3 Ti500 640x480 = 238.6 fps 800x600 = 236.6 fps 1024x768 = 223.5 fps Athlon XP 1900+ (1.6Ghz, non-overclocked) Geforce3 Ti500 640x480 = 265.0 fps 800x600 = 260.4 fps 1024x768 = 237.5 fps Now for my overclocked settings... AthlonXP 1900+ (1.8GHz, 150fsb) Geforce3 Ti500 @ 260/570 640x480 = 296.7 fps 800x600 = 290.6 fps 1024x768 = 263.9 fps Now.. as far as Chess goes I think 90% of you know there is absolutely no competition when it comes to P4 vs Athlon(xp/mp/etc). Here's some numbers off my crafty benchmark page.. (http://12.255.147.62/crafty/bench.html) Crafty v18.11 (each version is optimized for the specific processor) AthlonXP 1.81GHz - 1,132,185 nps. Thunderbird 1.67GHz - 1,041,610 nps. Pentium 4 1.7GHz - 687,406 nps. Celeron 1GHz - 575,475 nps. Pentium 4 1.5Ghz - 569,185 nps. As you can see even a Celeron at 1GHz is faster in chess (in crafty) than a Pentium 4 1.5GHz. I don't have results of a P4-2GHz but Crafty's speedup is basically linear on the same cpu... so a P4-2GHz 'should' get around 800knps. As far as stability there is absolutely nothing wrong with any of the AMD chips. If you buy a motherboard with some noname off the wall chipset that was only $50 I can guarantee you're going to have problems.. same goes for buying any piece of garbage. Get a quality motherboard, ram, videocard, etc and you won't have any problems at all. From what I can see so far there is absolutely no reason anyone should get a Pentium 4 when upgrading. They are a waste money.
