  2. Re: Number crunching using Single precision SSE regs

    Hi Charles,

    maybe, I had SSE in buffer 1 abd FPU in buffer 2, maybe it affects. I used 1000000 loops in ThinBasic, could be it.

    7600 is great card, I eNVy you :) But similarly to my GF6, it has...

    Hi Charles,

    cool code indeed!
    SSE performs 1.25x faster than your classic code. Not bad result for your solution, as I would expect SSE to make it lot faster :)
