AMD64 "TOP PERFORMANCE" BIOS option is rubbish

[K.I.L.E.R]

The A64 is faster using SSE2 vs SSE.

The BIOS option is meant to use SSE instead of SSE2 when SSE2 is requested.

TP set to off vs on is a couple hundred points faster under the latest version of SANDRA.

Tests were run in MM and arithmetic, both showed improvements.

run it in games and u will see why.

THe a64 is meant for games not sandra which is completely made for p4s .

I ran several runs of each mode in the UT03 benchmark.

The only thing which changed is the decimal numbers.

Hmm. I can tell u in some other games it goes up by as much as a fps or more .

Can't tell u the two games though

I've played through other games and the like noticing increase with it off. Increases are much larger too than a couple fps.

I used UT03 as a baseline because of it's "system" sensitivity.

Ehum, SSE and SSE2 are not interchangeable.

SSE is single precision and SSE2 is double precision. The maximum throughput (per clock) is 4 for SSE and 2 for SSE2.

Yeh it's weird.

That's the explanation I got from reading other sites and their reviews.
