    I usualy tend to buy this segment of graphic cards, but what are the differences between them. I have seen a lot of reviews about them both and from the number and cost all can say directly the 5770 is better. I was thinking which is the best third party and is it worth to spend more money on 5770? or better sticking to 5750? (in fact i want more knowledge about these two cards, not that i am going to buy them whith the current system)

    Thank you!

    The only difference is the 5770 is more powerful. It uses a little more power at full load, but produces better frame rate. It would be like comparing your current 7600 GS to an 7600 GT OCed. While they are fundamentally the same card, the 7600 GT OCed will give much better frame rate.

    To understand the difference between these two I think it's a good idea to imagine the difference between a 4850 and 4870 (or 4770 v. 4850) gpu. They are both very powerful cards, but the 4870 has an advantage out of the box. You can overclock the 4850 and get roughly 4870 levels of performance, but if you do the samething to the 4870 then the gap is just that much larger.

    It's been shown that if you OC the 5750 that you can get the level of a 5770 if you're looking to OC the card and 'save' money. However if you do the same to the 5770 (which overclocks like mad as well) then you will have a FAR greater performance than the 5750 OC'd.

    A 5770 is roughly equal to or greater than a 4870 depending on the application. If you overclock it then it gains a very significant performance increase while still using very little power. 5750 is roughly equal to or greater than a 4850 depending on application. Again if you overclock it then you can get a higher performance level.

    When I had to make that choice between the two cards I went for the 5770 so that I didn't have to OC the card unless I really wanted to in the future. Both have extremely similar power draws and run very cool at all times. I also like the look of the 5770's over the 5750 with the egg shaped cooler (not a bad cooler at all though) so that went into my decision.

    Personally I believe it's worth it to spend the little extra and pick up the 5770 if you are buying the card for a significant game use, if your are only playing the occasional game (especially an older non demanding game) then go for the 5750.

    Also obviously in comparison between the 4850 and 4870 they used different memory, GDDR 3 and GDDR 5 respecectively.

    The 4850 vs 4830 is a much better example. ;)

    ATI uses product binning. So if the GPU is ok for all the units are ok, it's a 5770 if not, it's a 5750.

    You might want to look and see if it has a lower memory bandwidth.

    Look people you guys are really not making sense. :laugh:

    When it comes to clocks here they are,

    HD 5770 has a 850Mhz core clock
    HD 5750 has a 700Mhz core clock
    ^^^^^^^^ Difference right there

    HD 5770 has a 1200Mhz memory clock
    HD 5750 has a 1150Mhz memory clock
    ^^^^^^^^ Diffrerence right there

    Hardware specs go like this
    HD 5770, has a 128-bit wide bus, 1gb of GDDR5, and 800 STREAM PROCESSORS.
    HD 5750, has a 128-bit wide bus, 1gb of GDDR5, and 720 STREAM PROCESSORS.

    So the HD 5750 has substantially lower clocks then the HD 5770, and has 60 less stream processors which basically do all the work. So the card should be 20% or more slower.

    Right now the HD 5770 is the better buy really, and i belive for the 20 more dollars you would spend in the USA for a HD 5770 over a HD 5750, you get a card thats ganna max games, and its going to OVERCLOCK way better then a HD 5750. So its a win/win, you buy a HD 5770 but get better overclockabilty, and way better performance before you even think about tweaking from a HD 5750. If you cant spare the extra 25 bucks then you can get a HD 5750 but anustly the HD 5770 is like the quality of a HD 5870 but with the half the stream processors, and bit wide bus. The memory clocks on these damn HD 5770's have been hitting INSANE speeds like 100+ gb of bandwith over 70-80 i belive haahahaha. Core clocks hits 1 Ghz.
    krisna159 and GSquadron say thanks.
