    A few months ago I found myself in a situation with a pair of HD4850s and 3dMark06. I was working on breaking 24,000 marks with 2 HD4850s and a Q9550 CPU. Seemed possible to me. Only problem was that one of my HD4850s died. Around the same time the HD4770 was barely hitting market. I decided to buy one to see how the 40nm gpu power of the HD4770 compared to the HD4850. Turned out the HD4770 worked much better in my system than the HD4850 so I sold the other working HD4850 and bought another HD4770.

    Since then I have come to appreciate the performance of the HD4770.

    From time to time I have shared my experiences with the HD4770 and I have discovered that there are people who debate that the HD4850 is better than the HD4770.

    This thread is an open invitation for HD4770 owners and HD4850 owners to compare benchmarks.

    This thread will show how these two cards performance compares and will serve as a tool to measure the performance of both cards.


    Rules.

    1. Any 3D benchmark can be used.
    2. "Hard wired" voltage modifications can be used but if done must be stated so.
    3. Software voltage "tweaking" of system is allowed.
    4. Any cpu/MB combination can be used.
    5. Complete system Specs must be shared with each benchmark score.
    6. Any type of cooling solution can be used but must be stated. If the system is in the case then it must be stated. If the system is out of the case in an open air environment it must be stated as well.
    7. Important!! Any benchmark posted must be from a member of the forum. Cannot post scores from any "proffesional review".



    That should be enough rules to start off this thread.

    In 3dMark06 the 4770s have a slight lead due to the ridiculous core clocks they can pull off....in real world gaming, I would suspect the 4850 would be faster due to more shaders.

    while its obvious what card SonDa5 prefers threads like these should be continued. It shouldn't matter how many forums he posts at and his enthusiasm should not be discounted.

    I have never been a big fan of online reviews and prefer to hear from trusted friends about real world experiences.

    Its good to see new products that use less power/make less heat and are similar in performance

    give the guy a break... benchmark your cards if you own any , post your results and stop arguing like little children . Nobody is forcing you to post here or even to read this . If you don`t like it skip this thread . It is actually interesting to see other people reviews on some crossfire setups with the HD4770 / HD4850 , different cooling , different tweaking , x8 / x16 speeds , and so on . What the hell people . If you don`t like this , get your toys and go play somewhere else .
    And to quote Acid :
    " I see this thread getting locked quickly and infractions being handed out "
    Are you serious ?

    And ontopic :

    I don`t own any of these cards but i can tell you one thing . The Asus volt tweak really pushes the Hd4770 to it`s limits / the bad thing is the power consumption witch is pretty high . Ive seen some core clocks on Hd4770 close to 970Mhz . Now that`s a real bump , right there . I am waiting for manufacturers like Gainward ( PALIT ) to come up with their own non-reference designs to see what value can they add to the table . Remember that not all of us are willing to spend 500$ for a video card and 200$ for a PSU to power it . The hd4770 was not built to beat down the Hd4850 , it was built for lower power consumption , lower temperature , higher stability . The HD4860 / 40nm ( rumor ) will get that job done . But anyway it`s nice to see other people experiences with the cards , and what they have to say about temps , crossfire setups , scalability , overclocking , benchmarking , and whatever ...
    I will sure come back here to check things up , because this is interesting . I honestly trust more the public opinion , than some hardware review sites , when it comes to benchmarking video cards . We all know some reviewers bump the scores sometimes ... this is well known . I`m not talking about TPU , these guys are great , i've spent a lot of time surfing around and reading product reviews here , and actually bought some stuff with confidence knowing i have some backup and knowledge about the product's performance .
    All the reviews sites out there cover just 5% of the games , so maybe there is someone that will show us how much performance difference is between HD4770 and HD4850 in Serious Sam I ( for example ) . I know this ain`t crossfire related , but it`s still something nice to see . We all are getting bored about the 5% difference in Crysis that we see everywhere .
    This is interesting , if you don`t like it , go away .

    You can choose to contribute or not in the thread, posting and making accounts just to bash him make you guy's look bad, let him be, he has a right to post what ever he likes and think what ever he wishes within the rules offcourse.

    I've had both cards theyre very much even, for some reason the 4770 OC'D spanks the 4850 In games like crysis and gets its ass handed by the 4850 in Prototype, both on the same system same bandwidth, the 4770 at 875 core amd the 4850 at 785 core that said difference is barely 5 to 7 fps maybe 12, I loved the 4770 but when the 4850 bacame 85$ that made me get some 4850 action price wise the 4850 is the better card in my opinion, priced equally there wouldnt be a diff for me.

    My o/c 4770 (910/1200) gives better performance than the overclocked 4850 (700/1100) toxic I used to have. But this might be (mostly) because of better drivers and even a better OS (win7).

    Here's my overclocking on 1vcore:

    (its not at 1.1v as I wrote on the GPU-Z validation link.)

    How does the 4770 compare to the 4870 then?

    Its difficult to see how even an overclocked 4770 could compete because the 4870 has a massively higher memory bandwidth. Although I must admit that I do not know how much the core is playing into it all.

    Btw, according to my kill-a-watt the o/c 4770 runs at full load (entire system) about 20w less than the o/c 4850. So it's easier to cool down and saves a bit energy. I had to use a 800rpm fan on the 4850 but a 600rpm is enough on the 4770.

    The 4770 takes the lead due to its higher capacity for clocks....for example, Kaleid's 4770 is clocked @ 910 on the core vs 700mhz on the 4850; that goes a long way to giving those 640 shaders on the 770 a healthy boost in games.

    If you could clock the 4850 to the 4870's core speed (750mhz) I'm pretty sure the 4770 would lose to the 4850 due to it having 800 shaders.

    Probably. But how many 4850 overclock well on the memory? Isn't it that which is actually making the 4870 so much faster than the 4850?

    They both have gddr5 too but the 4870 is 256bit compared to 128bit on the 4770.They are good cards them 4770's though.

    4770 - 640 Shaders - 128bit - GDDR5
    4850 - 800 Shaders - 256bit - GDDR3
    4870 - 800 Shaders - 256bit - GDDR5

    If you look above you will see the 4850 is held back by its GDDR3, if it had GDDR5 it would slap the 4770 silly....on the other hand, if the 4770 had 800 shaders it would waste the 4850.

    The only thing what saves the 4770 is the fact it clocks so well compared to the 4850; if said 4850 would clock to 750mhz+ core it would beat the 4770 every time especially at higher resolutions because its extra shaders would be working harder than they are at 700mhz~ thus returning better fps.


    The 4870 has both GDDR5 & 800 shaders with the full 256bit bus width...this puts it miles ahead of them both when it comes to benchmarks and gaming and it can clock very well too, 800mhz is easily done and 1050+mhz on the memory is almost a given.



    Bottom line: The 4850 & 4770 trade blows, one wins in one game, the other in something else...there is no clear winner on performance and other factors such as power draw, residual case heat and most of all the price should be used to decide what one to get.

    no hard proof due to never owning a 4850, but do the 4770's scale better in crossfire vs the 4850's.

    Impressive new performance with the 9.8 hotfix performance for HD4770s in Xfire.


    RE5 Benchmark.

    I really wanted to try the 4770s. I just havent been able to find any and I have a feeling by the time I do the next big thing will be right around the corner.

    Thanks SonDa5 for the post..

    I have an old 06 result from my vmodded HD4850 @ 900/1100.

    [​IMG]

    I also have a vantage run, but I don't have the screenshot anywhere, but the clocks are also 900/1100 on the card, and the cpu is only at 3.6GHz. Score was 9906. Here's the Orb link: http://service.futuremark.com/compare?3dmv=602299

    Keep in mind, this is on h2o with a vGPU mod to 1.35-1.4V.

    Awesome score for a single HD4850.


    Here is a single HD4770 OC for comparison. :cool:

    Software voltage mod to around 970/1100.

    Yeah, unfortunately, my run is on a "dirty" XP install, and much older drivers (Cat 8.10). I'd like to see what it could do with the newer drivers, and on a clean install, but I'd have to tear down my gpu loop to test. I bet I could get close to 19k with it.

    That would be epic. I'm sure I could squeeze some more out of a single HD4770 as well. :toast:

    Surprisingly, two 4770's would be around 1 1/2 +/- times the performance of a 4870 (stock).
    In CF, two 4850's would be more than than the 4770 CF; but, if you OC the 4770's, you would see much better scaling on the 4770's.
