Synthetics

As always we’ll also take a quick look at synthetic performance to get a better look at our video cards' underpinnings. These tests are mostly for comparing cards from within a manufacturer, as opposed to directly comparing AMD and NVIDIA cards.

We’ll start with 3DMark Vantage’s Pixel Fill test, a mix of a ROP test and a bandwidth test to see if you have enough bandwidth to feed those ROPs.

Moving on, we have our 3DMark Vantage texture fillrate test, which does for texels and texture mapping units what the previous test does for ROPs.

Finally we’ll take a quick look at tessellation performance with TessMark. We have everything turned up to maximum here, which means we're looking at roughly 11 million polygons per frame.

    Well said, and thanks. I no longer visit Dailytech for the same reasons. I enjoy reading comments, since they can offer other perspectives from like-minded people, but unmoderated is worse than nothing at all. This used to be my favorite tech site, but the comments section here has slowly been pushing me to avoid it most of the time. Reply

    Suddenly Fermi is forgotten and it's only now that AMD will edge out nVidia on power efficiency. Reply

    The 7790 reminds me of the 4770. Sure, that was on a new process node, but it's a late addition to the line designed to take advantage of tweaks, process improvements, etc.

    There may be a lot of transistors in a GCN design but I couldn't help feel that there were power savings to be had. For this reason, I'd hope that their next flagship doesn't exceed the 7970GE's power draw whilst providing a decent performance boost.

    Good article, very detailed.
    I think NVidia is replying to this with the new 650 Ti Boost.

    1 GB VRAM is ridiculous, especially for a $150 product. Reply

    For those who want the most power in the smallest package and power drain, look no further then the Radeon 7790. The only disappointment was the heat factor, but more or less the same performance as 7850 at half the power; that's great. Also, I don't mind that AMD went the 6 ghz vram route, because now there is even more reason to get 2 GB which is especially needed if you apply a dozens or hundreds of mods to your games. Also its the 128 bit interface that kept the power low, so despite everyone's cussing AMD made the right choices. I have a GTX 460 which easily uses at least 200 watts. This 7790 is almost twice as fast and uses 2.5 times less power. The pricing is acceptable, if you were to include 2GB by default, then why bother with the 7850; they still want ppl to buy that one.

    Hey Anand, can you guys please do a video quality test? I mean I haven't seen any such test on any website for over 3 years. So please, can you do a video quality test in movies and games and please also use low quality video as well, not just top of the line 1080p type videos that would look amazing even on a GeForce 3.
