Radeon HD 5770, Radeon HD 4890, And GeForce GTX 275 Overclocked

Graphics Chips Compared And Test Setup

Each of our two MSI cards appears in this table three times. Both models are sold as OC editions, meaning that they run at overclocked speeds to begin with. Since the higher frequencies are coded into the BIOS, we consider them the cards’ stock frequencies, so they show up in the table under their normal model name. We also tested each of the cards at the reference speeds specified by Nvidia and ATI, respectively, labeling their scores as “No OC.”

In our third test, we tuned the factory overclocked MSI boards even further. This setting is labeled “Max OC” in the table. ATI’s Radeon HD 5770 is the only DirectX 11-capable card, and it uses ATI’s reference design. Its overclocked scores are marked as “OC” in the table, simultaneously representing the maximum overclock we achieved.

To put the score in context, we decided to add results from various cards that we have already tested running at stock speeds. To ensure that none of the cards was being held back by the CPU, we chose a Core i7-920 overclocked to 3.8 GHz as the heart of our testing platform.

A word of warning: these overclocking tests are by no means a recommendation for your hardware. Overclocking can damage your graphics card and may void your warranty. Make changes to your card’s clock speeds at your own risk.

    Nice article. Ever since the 5770 came out I've been wondering how far someone could push the memory to relieve that bottleneck. Being able to push it to 1430 allows it to be competitive to it's older sibling and makes it enticing (with the 5700 series' extra features of course)
  • Onyx2291
    Damn some of these cards run really well for 1920x1200 which I run at. Could pick up a lower one and run just about anything at a decent speed if I overclock well. Good ol charts :)
  • skora
    If you're trying to get to the next cards performance by OCing, shouldn't the 5850 be benched also? I know the 5770 isn't going to get there because of the memory bandwidth issue, but you missed the mark. One card is compared to its big brother, but the other two aren't.

    I am glad to see the 5770 produce playable frame rates at 1920x1200. Nice game selection also.

    I'm really disappointed that they aren't any benchmarks from the 5870 or 5850 series included. Why even bother with tha GTX 295 or 4870x2 and such without the higher 5-series Radeons?

    I mean if I'm considering an ATI card, I'm going to want to compare the 5770 to the 5850 and 5870 just to see if that extra cost may be justified, not to mention the potential of a dual 5770 setup.
  • presidenteody
    I don't care what this article says, when the 5870 or 5970 become available i am going to buy a few.

    Well, at least in Germany 4870 costs quite a bit less (30-40 Euros) compared to 5770. It would take 2+ years of playing to compensate for it with lower power consumption.

    "Power Consumption, Noise, And Temperature" charts are hard to comprehend. Show bars instead of numbers, maybe?
  • arkadi
    Well that put things in prospective. I was really happy with 260gtx numbers, and i can push my evga card even higher easy. To bad we didn't see the 5850 here, it looks like the optimal upgrade 4 gamers on the budget like my self. Grade article overall.

    I got lucky with my card. Before, I had a SuperClocked 8800GT from EVGA. I ordered a while back, a new EVGA GeForce GTX 275 (896MB). I figured the extra cash wasn't worth getting an overclocked model particularly when I could do it myself. I get it, I try to register it. The S/N on mine was a duplicate. They sent me an unused S/N to register with. I then check the speeds under one utility and it's showing GTX 275 SuperClocked speeds, not regular speeds. I check 2 more utilities and they all report the same. I had paid for a regular model and received a mislabeled SuperClocked. Flippin sweet.

    Now they also sell an SSC model which is overclocked even more. I used the EVGA precision tool to set those speeds and it gave me like 1 or 2 extra FPS is Crysis and F.E.A.R. 2 already played so well without overclocking. So overclocking on these bad boys doesn't really do much. Oh well.

    One comment though, GTX 275's are HOT! Like, ridiculously hot. I open my window in 40 degree F weather and it'll still get warm in my room playing Team Fortress 2.
  • With the 5970 out there seems to be nothing else about graphic cards that interests me anymore :D Its supposed to be the fastest card yet and beats Crysis too!
