Um, Might your Athlon actually be a Duron?
In that case, you are comparing a Celeron-like CPU with a PIII, which hardly is fair.

The L2 cache size for the Athlon (Thunderbird) is 256K, just like the PIII (Coppermine).
The L2 cache size for the Duron is 64K, while the comparable Celeron has a 128K L2 cache.
All AMD K7s have a 128K L1 cache, while all P2 and PIII chips have a 32K L1 cache.
Some tests show the Duron almost outperforming the Coppermine at the same speed, and that might be what you are seeing here.
