AMD Radeon HD 7790 Review: Graphics Core Next At $150

Results: Crysis 3

It goes without saying that Crysis 3 can be made particularly demanding as you scale up detail settings. So, in order to run at 1920x1080 on these mid-range cards, we're using the Medium preset with motion blur and lens flares disabled (though we turned on 2x SMAA to smooth the edges).

The Radeon HD 7790 keeps up with AMD's Radeon HD 6870 and Nvidia's GeForce GTX 560, while the GeForce GTX 650 Ti falls back a little. Notice that all of the GeForce cards are hit with lower minimum frame rates in this game.

When we look at the frame rate over time, we see sharp valleys from Nvidia's cards. We noticed these strange pauses during game play, and they are causing the low minimum frame rate results. Further experimentation tells us that this is caused by the new 314.21 beta driver; the issue disappears when we switch back to 314.07.

The frame rate variance is a little higher than it was in Borderlands 2, but it's still under the 15 ms limit where we'd start to notice issues. Despite encountering pauses on the GeForce cards, frames seem to be showing up on-screen at regular intervals.

    I thought the HD 7850 1GB is good value at $150 after rebate and 2GB at $180 after rebate.

    Its crazy to see how much performance you can get in $150. The HD7790 performs 90% of the 6870, which menas its almost equal to a HD5870 :O , which was the top chip a few years back.

    Very good performance for the price.

    Its a good time to build mid end systems :)

    Too bad the OpenGL benches weren't implemented before Tom's did that "Gaming on workstation GPUs" article...

    I guess I know what my next GPU will be.

    6870 performance in a 85W envelope is amazing.

    Glad to see some competition at entry/budget level card.....

    wow, nice job AMD...

    and perhaps they finally realized that they make crappy reference coolers at best and just let Sapphire go ahead and ship to Tom's lol. In all honesty, as an AMD exclusive partner, Sapphire should just go ahead and take over reference cooler design for AMD, they make some awesome stuff

    amdfangirlI guess I know what my next GPU will be. 85W TDP... basically = to a HD 5870... I can't believe it...I'll get the 2GB and finally be able to play Skyrim 1080p w/high res textures xD.
    IDK about it at that point. High-res stuff and all that can eat through poor memory bandwidth cards such as this quite easily.

    Honestly, if you put on enough high res mods, even my 7970 barely keeps up... still a gorgeous game tho, and you'll enjoy it just fine with a little tweaking and a 7790

    Well, it seems to not hold up quite to the 90% of a 7850 rumors, but it's at a respectable ~80% of it on average. For $150, that is definitely a great competitor.
