  • what does 512 bit really mean?

    forgive me for being dense but being a 512 bit gpu parhelia should be able to process 512 bits per clock cycle, contrast this to the compition which are 256 bit and clock for clock parhelia can process twice as much , so why does it mean a relatively low clocked parhelia(220mhz) will be slower than a 300 mhz gf4 as the 220mhz should be equivalent to a 440 mhz gf4 due to it processing double the data per clock cycle, or have i got totally the wrong end of the stick here?
    is a flower best picked in it's prime or greater withered away by time?

    no you are absolutely right(i think), the problem is the no games(yet) is designed to give the gpu that much datainput, however when next gen games makes uses of more texturelayers/pixelshaders/polygons etc. then will parhelia most likely beat the gf4ti by a large margin.

      I've been wondering about this (the P beating GF4 for complicated games). The impression I get is that the P will beat GF4 in those circumstances where (minimal) FPS will be unplaybly slow anyway. So what if u get 8 FPS from a P and it's twice the 4 FPS the GF4 yields?

      Lower resolution and quality would raise the FPS, but I get this feeling that the GF4 would increase more and overtake the P. Does this make any sense?

      Same goes for surround gaming. It may be awesome in concept, but one might have to sacrifice a lot in quality and res for it to have playable FPS.

      Just wondering....
