Scumbria,

Prefetching into the L2 could produce significant gains for Linpack-type code, so it is possible that some benchmarks will see 50% improvement (if they actually did that.)

But someone (I can't recall who) posted that all of the data from RAM goes to L1 in Athlon, not L2, and it only gets to L2 when it gets evicted from L1. Is this a correct (at least in the ballpark) representation of how Athlon works? if it is, it seems to preclude prefetching to L2.
