Prcessor Settings:

11.5x133 MHz = 1533 MHz
12.5x133 MHz = 1666 MHz
10.0x150 MHz = 1500 MHz
11.5x150 MHz = 1725 MHz

SiSoft Sandra 001
3DMark2000 Ver 1.1
Quake III Arena Ver 1.17
Return to Castle Wolfenstein

I'm limited to a 12.5 multiplier bor benchmarking but was able to overclock the FSB to reach 1725 MHz.

As we can see, the AthlonXP1800+ scales very well even at stock, unfortunately the Mutli-Media bench is pretty much useless... Still, it does put the Athlon in a good light. In all honesty, I don't really understand how this new version of Sandra works. From now on, I think I'll be downgrading to the older version 2001TE. Take this how you will. Let's take a look at some 3D benchmarks.

MadOnion 3DMark 2000 Ver 1.1
Setting: 3D Marks
11.5x133=1533 MHz 11037
12.5x133=1666 MHz 11271
10.0x150=1500 MHz 11127
11.5x150=1725 MHz 11403

3DMark2000 doesn't really seem to see the differences between the systems. Still, there is a 400 point difference between the slowest and fastest systems which is more than the margin of error.

MadOnion 3DMark 2001
Setting: 3D Marks
11.5x133=1533 MHz 7700
12.5x133=1666 MHz 7866
10.0x150=1500 MHz 7774
11.5x150=1725 MHz 7993

3DMark2001 can differentiate between the different configurations... Still, the scores are a lot closer then I thought they would be. Maybe even with a GeForce3, I'm videocard limited?

Let's see what Quake III thinks...

Quake III Arena Fastest Setting


11.5x133= 1533 MHz
265.6 fps
76 fps
12.5x133= 1666 MHz
272.5 fps
79.3 fps
10.0x150= 1500 MHz
268.6 fps
77.3 fps
11.5x150= 1725 MHz
282.7 fps
81.5 fps

Yes I knew good ole Quake III wouldn't let me down. As we can see here, there is quite a gap between the slowest and the fastest settings. Next up is the very popular Return to Castle Wolfenstein based on the Quake III engine.

Return to Castle Wolfenstein Max 640x480


11.5x133= 1533 MHz
54.7 fps
141.6 fps
12.5x133= 1666 MHz
58.9 fps
154.8 fps
10.0x150= 1500 MHz
55.7 fps
150.8 fps
11.5x150= 1725 MHz
60.6 fps
159.3 fps

RTCW confirms everything else we've seen here today. The XP CPU does scale quite well. Well what else really needs to be said about the AthlonXP processor?

Even at stock speeds, it is a force to be reckoned with and when it's overclocked nothing can compete with it! It's the fastest processor out there to date. Ever since AMD released the Athlon line of processors, they've been setting the tone. Sure things might change with the release of the Northwood Pentium 4 with it's higher bus speed and 512KB L2 cache, but then again AMD will counter with it's Thoroughbred. It's certainly a great time to be a consumer right now!
