    I once measured Amps for OCs, giving an idea about the clock/Wattage curve (of course Volts are always to make it stable):

    900 1.100V 39.5A
    900 1.125V 41.8A
    950 1.149V 44.1A
    960 1.187V 48.8A/49.9A
    970 1.212V 51.1A/52.3A
    980 1.250V 55.7A
    990 1.274V 58.1A/59.2A
    1000 1.300V 61.5A

    As it's really long ago I can't reproduce the Amps for the regular 850 (I don#t even remember the setting, just that all number came from the same setting), let's pull it out of the arse^H^H^H^H cognitive extrapolator:

    850 1V 35A = ~35W
    1000 1.3V 62A = ~80W

    I did not write down anything else, and I can't measure the cards entire Watts I think. Maybe someone of you can make something out of it. Is it enough data to get an idea about how much core-clock we would have with a hypothetical 300W 5870?

    http://www.techpowerup.com/reviews/NVIDIA/GeForce_GTX_480_Fermi/35.html

    Cod4 1920x1200 4xaa 16x af
    5870 115.1 fps
    480 119.3 fps
    480oc 129.4fps 770mhz core overclock 1048 memory best stable oc they could get
    5870oc 132.3fps 1ghz core 1225 memory


    5870 oc temp

    Idle 30c
    load 66c
    Load+ oc 70c

    gtx 480 oc temp

    Idle 65c
    load 96c
    load oc 96c


    The 5870 has alot of head room in terms of heat.. Even overclocked at 1ghz its usoly 5c higher than the gtx 480 stock at idle !


    I wonder what ati can put out 6 months later with higher voltages and a better cooler ?

    Is it just me, or did no-one test the new AA modes? Everyone for what I checked quickly seemed to just quote nV numbers without actually testing them

    Congratulations, you found 1 test in all the internets to support god knows what idea...

    Here's a few. There are probably many more but eh.
    Guru3D: Overclocking the GTX 480
    Overclockersclub: 480 GTX
    Legitreviews: Overclocking GTX 480
    Hardware Heaven: GTX 480 overclocking

    Oh, Nvidia apparently provided an updated version of EVGA Precision along with the cards so reviewers could play with it.

    You guys :)

    We are discussing that if ati didn't care about power and heat they could put out a competing part.

    1ghz 5870 runs only 5c above an idle gtx 480.

    Its obvious that there is room for cypress to grow. 1-1.1ghz core with 2gig framebuffer of 1.3-1.4ghz ram should make for a very competetive place if they wanted to go that way.

    Yes, 900 ...

    I expect something like 1350MHz+ core within 300W. Where is the review comparing 300W 5870 vs. 300W 480? Or a 190W 5870 vs. a 190W 480? I guess you have to go LN2 on 5870 to even hit 300W.

    perf/watt, perf/mm2, perf/dollar, cost^time ... where just does the 480/470 yield? :?:

    No. We are not discussing anything. I was addressing aaronspink's specific claim that a higher clocked 5870 would likely outperform a GTX 480 most of the time.

    i provided a case where it does. Do you have other cases where a 1ghz ne doesn't ?

    Read my OP until you get it; if you don't get it, that is your problem not mine.

    An overclocked 5870 with 2 Gigs of memory would close the gap on a 480 GTX, the minimum framerate is most certainly affected at those crazy resolutions with high IQ settings by video memory that maybe 1% of PC gamers play at.

    So your unable to share this review that you claim to have seen ?

    I at least backed up my claim.

    Yeah, sure looks like it is at the end of its clocking rope to me.

    Multiple times in various time frame was 2-3 second, which if you look at the [H] charts, those monster dips are in the 2-3 sec range. Just enough to cause a slide show.

    Within a retail envelope it certainly is, at 825 MHz, even if the real TDP for the base card was only 250 (which nvidia has admitted that it is higher), that card is pulling north of 300W. If you believe that the real TDP is likely in the range of 275-300W for the 480, then that card is easily north of 350W.

    OTOH, ATI can increase their power by at LEAST 75W and still be within the PCIe limit. In other words, ATI could if they wanted to, likely release a ~950 MHz card right now with their current 5870 parts at roughly the same power envelope as the 480.

    Yes, memory could be an issue at ultra-high resolutions and AA, but this doesn't explain Fermi's apparent speed advantage at low resolutions. It could be that triangles are too small at the lower resolutions, and bumping the clocks might not improve this much.
