    he is talking about the pictures behind click links .. they are 800x600 now, and he wants 1024x768 which sounds reasonable. i'll look into it
    thumbnails wont be made any bigger for the forseeable future

    W1zz, is the 5770 really a bit wider than the 5850/5870 or is it just an optical illusion and the difference in length just makes it appear that it's wider (with the 5770 being shorter than the other cards)?

    5850 and 5770 seem to be 2 or 3 mm wider than 5870, nothing worth mentioning. i wouldnt have noticed it

    Is that overclocked memory really sitting at 6000MHz effective speed? :twitch:

    The "artifact eliminator" wasn't sacrificing performance at that speed?

    Yeah this creeped on to newegg last afternoon, woke up, and a review appears! Card appears to be nothing good, maybe just a tad better than my 4850, but really, feels kinda worthless IMO.

    Well that's weird. I see no difference between the 5850 and the 5870, but the 5770 really looks almost a cm wider than the two, even after a second look. :p Must be just an illusion due to length differences as well.

    I was thinking the same thing, but just could not bring myself to say it. These cards only make sense to someone who skipped the entire 48xx and GT200 generations. Or someone building a whole new computer and wanting mainstream gaming capabilities. The 4770/4850/4870 will soon be out of the channel and these will be the only options. They are good replacement cards, but not exciting in anyway.

    yes, it scales to that and is stable, i know what i'm doing :)
    AhokZYashA, BradleyKZN and Scrizz say thanks.

    This card is awesome at the price point. Sips the juice and can play with the big boys. I lurve it.

    WOW @meme OC!!
    Would it be 512 bit and u d have 384Gbps bandwidth!

    These cards have 1GB too, so that's more like apples to apples. In Wizzard's charts the 5770 isn't faster than 4870 512 MB either (except at 2560x1600). Anyway, the specs of the card, sans the memory bandwidth, should make this card as fast as the 4890 and not the 4870.

    It's memory bandwidth limited. The fact that the OC benchmark show a greater performance gain (11,4%) than the core OC (9%) also suggest the bottleneck. Look at any other review, the performance gain usually never gets close to the OC.

    if those cards really were memory starved then wouldnt reducing the core clock result in no performance decrease at all?

    I think you're right. Reducing the core would have little effect on performance because the core is waiting on data from the memory. (assuming they are in fact memory bottlenecked)

    However, has this been tested? (Did I miss something)

    Anyway, you don't contradict Benetanegia. Both of what you say can be true. It's just that W1zzard's test would be a conclusive test. (Can we get a quick test?)

    i'm just asking if we agree with this testing method .. i can run some benchmarks later .. right now g 210 is running in the vga benchmark rig

    Do some test at stock speed. Do a core only OC. Then do a mem OC only. And you can toss in a core+mem OC just for comparative purposes. That would show how much of an effect each OC has on performance. So the % gain vs % OC. [EXAMPLE] If you see a 10% gain from a 25% mem OC only and a 10% gain from a 10% core OC only, then you can see that OCing the core is more effective.

    The underclocking is basically the same thing in the other direction. Your test of just underclockign the core will show how memory limited the card is.

    Hopefully that makes sense.

    nice cards and reviews as always , as rule of thumb ignoring the DX11/low heat-power of the new cards and considering worst case scenario for pure performance.

    4770 = 4850 = 5750

    5770 = 4870

    what difference would this make?Since shader clocks run at the same speed as the core?

    That is some insane memory OC.


    Was the GPU at stock voltage for the overclock, and if we might ask what voltage does it show in the drivers on on the card if you have the voltage test points figured out? Do you plan on redoing some of the benchmarks with DX11 titles when they hit?



    Awsome review, one of the biggest reasons I was drawn here, and remain.

    as the page says: stock fan and voltage settings

    not sure about dx11 yet .. how would i compare nv dx10 w/ ati dx 10.1 w/ ati dx 11 ?

    I'd like to get a couple. Would be a nice move from my current card.
