ATI Radeon HD 4770 In CrossFire: Unbeatable At $220

Benchmark Results: Crysis

Here we have the twin 4770s and single 4890 going to head-to-head, outperforming the Radeon HD 4870 and GeForce GTX 260. The individual Radeon HD 4770 is included for reference, but really isn’t expected to be a contender here. It’ll be interesting to see what adding anti-aliasing (and applying greater demands to the memory sub-system) does to separate the top two finishers here.

As suspected, a mere 512 MB of frame buffer per card hurts the Radeon HD 4770’s performance, and the 1 GB Radeon HD 4890 takes its lead back. Even the 1 GB Radeon HD 4870 pulls in over the two 4770s at 1680x1050. The difference isn’t huge, but you will need to keep these cards’ limitations in mind. Pushing additional fill rate and compute power only takes you so far once you start turning up resolutions and turning on eye candy extras.

    Working on getting the drop-down or ToC on every page. Sometimes things are changed without advanced notice. Trying to get a solution for you guys!

    Great article. Just for kicks, how do the xfires of the 4830 and 4850 compare to the xfire 4770?

    How about a dual column menu table? My mobile browser doesn't like to work with drop-down menus. I know, just nick picking like everyone else. :D

    I have already mentioned the drop down issue, but I am mentioning it again for emphasis. Consider Bert Lance's saying, "If it ain't broke, don't fix it." By the way, nice article.

    The other day I was trying to prove to my brother that 2 ATI 4770's would outperform anything in its price range and my brother didn't agree with that... lol I can't wait to show him the article.

    Unfortunately, he already bought a 4850 card which he should be okay for now, I guess.

    Anyways, great article. I really enjoyed it. :)

    Just put in the URL to jump to the page you want, for now.

    For example -,2288-3.html will get you to page three.,2288-5.html will get you to page five, etc...

    Hmmm I wonder how three of these would scale together. Nice article as well, very interesting how this compares to the other cards
