Trif, could you please re-run the benchmark on 23.5/23.6? It's interesting to see if the 512KB cache of the Athlon actually made any difference to Prime95.

Cheers!

Here ya go:

AMD Athlon(tm) XP 3200+
CPU speed: 2204.91 MHz
CPU features: RDTSC, CMOV, PREFETCH, MMX, SSE
L1 cache size: 64 KB
L2 cache size: 512 KB
L1 cache line size: 64 bytes
L2 cache line size: 64 bytes
L1 TLBS: 32
L2 TLBS: 256
Prime95 version 23.6, RdtscTiming=1
Best time for 384K FFT length: 27.802 ms.
Best time for 448K FFT length: 30.488 ms.
Best time for 512K FFT length: 32.915 ms.
Best time for 640K FFT length: 44.244 ms.
Best time for 768K FFT length: 52.603 ms.
Best time for 896K FFT length: 63.324 ms.
Best time for 1024K FFT length: 70.255 ms.
Best time for 1280K FFT length: 92.251 ms.
Best time for 1536K FFT length: 109.822 ms.
Best time for 1792K FFT length: 136.849 ms.
Best time for 2048K FFT length: 147.958 ms.

Note this is on Win98SE, which is slower than the newer operating systems. The torture test failed last night in the middle of the 64K FFT, so I am using the new features of 23.6 to pound the CPU with small FFT sizes.

Xyzzy, how are you getting a 3200+ rating with a speed of only 2090?

BTW, I only have one stick of memory, so my benchies don't reflect the dual channel capabilities of the NForce2 chipset.

Now if I could just figure out why the torture test is failing the 64K FFT and only the 64K FFT.

I have no idea!

Maybe it has something to do with the AMD's 64K L1? (Just guessing here!)

Maybe somewhere in your system the CPU is recognized as 3200+ or reported so by the BIOS.

Surely not. 64K means 64K double values, not bytes.

That's interesting....

How come Prime95 benchmark sometimes reports the CPU model number and sometimes it doesn't?

Mine only said "AMD Athlon(TM)" while some of you guys are getting
"AMD Athlon(TM) XP 1800+ (Thoroughbred)" (as an example).

I think it has to do with what the BIOS says. The (Thoroughbred) may have been added by the poster to distinguish it from a Palomino. With a Barton you can tell by the cache size.

Best time for 2048K FFT length: 73.574 ms.

Once I get my new Antec True430 Power Supply I should beable to hit atleast a 3.4ghz benchmark. Even know someone who has hit higher with his 2.4B.

This is on a 2.4B, Soyo Dragon Ultra P4X400 board, 256mb of PC2100 Ram, and a very crappy power supply.

This is a XP2400+ on an Abit NF7-S Ver. 2.0 with 512MB of PC3200 DDR memory. My XP2400+ appears to be completely stable at a 200MHz FSB.
