Artikbot Posted March 13, 2012 Share Posted March 13, 2012 Good evening, I've been working lately with some old AGP graphics cards, to see how well do I fare in a completely CPU bottleneck free platform, and where the processor clocks aren't as important as in other platforms. Well, to my surprise, when submitting scores some of the cards I work with don't discrimine between 64 or 128bit bus widths. On newer PCI Express cards this doesn't pose that much of a threat, but on AGP that memory bus width can (and does) affect performance quite a lot. For instance, take this FX5200 submission I made: http://www.hwbot.org/submission/2264760_artikbot_3dmark2001_se_geforce_fx_5200_7228_marks I ran the card to the clocks that gave me the best performance (305/500 - 250 DDR). Now look at, for instance, this submission here: http://www.hwbot.org/submission/886061_student_3dmark2001_se_geforce_fx_5200_9711_marks He gets more than 2000 points more, while running at remarkably lower clocks. The only difference between our cards is the bus. He has a 128bit-wide bus while I run a 64-bit narrow bus. What I mean is, there is no contest for 64bit card users if there are 128 bit versions, because with little effort, a 128 bit card can easily score a 30% more points than a 64bit one overclocked to hell and beyond. Thanks for your understanding! Quote Link to comment Share on other sites More sharing options...
