    It's my impression that AMD cards are more responsive to clock frequencies, while NV cards are rather dependent on units/clusters. We've seen it from GTX 260 vs. GTX 280, as well as 8800 GTS vs. 8800 GTX. There were situations where GTX 280 / 8800 GTS can't come over the performance of their older brothers, even with massive overclocking. (and their clock generator don't generate clocks linearly)

    Just a thought.

    BTW, great article but very long and time consuming xD to interesting. Keep up the great work!

    Doesn't AMD make the cards a whole different way then Nvidia? Don't they have like really high clocks and memory while Nvidias is a lot lower with higher of other parts?

    Also has Nvidia made a card that's simply overclocked like the 4870/4890?

    ATI has lost TWO BILLION DOLLARS SELLING THEIR GPUs ! A BILLION A YEAR EASY - YET DEREK HAS THE UNMITIGATED GAUL TO SAY THIS:
    .
    " In the meantime, NVIDIA's margins are much tighter on their larger GPUs and now their single GPU performance advantage has started to erode. It seems the wonders of the RV7xx series have yet to exhaust themselves. "
    ROFLMAO !
    THAT MIGHT MAKE SENSE IF ATI HADN'T COST AMD A BILLION PLUS A YEAR ON BARELY 2 BILLION IN SALES! ATI IS LOSING 33%.
    THEY SELL $100's OF ATI CARD, THEY LOSE $33 !

    THE TRUTH REALLY REALLY SUCKS , HUH RED ROOSTERS !

    THE ARTICLE HERE " We absolutely must caution our readers once again that these are not off-the-shelf retail parts. These are parts sent directly to us from manufacturers and could very likely have a higher overclocking potential than retail parts. "

    LOL - WELL THAT SHOULD ANSWER YOUR QUESTION !

    cocka doodle dooooo ! cocka doodle doo ! red rooster rides again !

    I had an NVidia Ti4200 that overclocked well - good enough to basically double the cards value. The original Radeon LE also overcloked well, and you could unlock extra pipes. I also still have an X800GTO2 that could be Bios flashed to an X850XT.

    I am not sure I understand what you mean by "simply overclockable"

    Just add the coolbits registry value to the classic control panel and there are two simple sliders. It has been that way for years.

    As far as the speeds you can reach, just take care that there is enough cooling and power (voltage bumps if need be).

    I learned how to shade a resistor and take voltage measurements over at vr-zone, I think Shamino has a tutorial for it.

    The most Overclockable card that I can remember from nVidia was the Geforce FX 5700LE it's stock core speed was 250mhz, I managed to crank my core speed on that card all the way to 640mhz on the stock Heatsink and fan, however thats not saying much as the 5700LE was basically a regular 5700 but with it's clockspeeds reduced to 5200 speeds, before that I had a Geforce 2 MX100 which was incredibly overclockable, and the TNT Vanta I had before it was as well, however I don't think I have seen a high-end part with that much overclocking margin.

    If you are willing to raise the voltage you can get really good overclocks.

    I had a 7900GS up to 720mhz (from 450mhz) before it couldn't take it. Backing off to 708-700 made it stable, so I settled for 650 and it has been rock-solid for 3 years.

    It all depends on the kind of cooling and power you can bring it.
