AMD Radeon HD 7790: Affordable DX11 Gaming

4 thumbs up

How We Configured Our Test Systems: We tested the graphics cards in this article on an Asus P9X79 Deluxe motherboard powered by a Core i7-3960X six-core processor and 16GB of G.SKILL DDR3-1866 RAM. The first thing we did when configuring the test system was enter the system UEFI and set all values to their "high performance" default settings and disable any integrated peripherals that wouldn't be put to use. The memory's X.M.P. profile was enabled to ensure better-than-stock performance and the hard drive was then formatted and Windows 7 Ultimate x64 was installed. When the installation was complete, we fully updated the OS and installed the latest DirectX redist along with all of the drivers, games, and benchmark tools necessary to complete our tests.

Unigine Heaven v4.0 Benchmark
Pseudo-DirectX 11 Gaming


Unigine Heaven v4.0

Unigine's Heaven Benchmark v4.0 is built around the Unigine game engine. Unigine is a cross-platform, real-time 3D engine, with support for DirectX 9, DirectX 10, DirectX 11 and OpenGL. The Heaven benchmark--when run in DX11 mode--also makes comprehensive use of tessellation technology and advanced SSAO (screen-space ambient occlusion). It also features volumetric cumulonimbus clouds generated by a physically accurate algorithm and a dynamic sky with light scattering.

Please note that we've underclocked one of the factory-overclocked cards to reference levels to show a more complete picture of performance. The Radeon HD 7790 represented in the graphs on this page, and the others moving forward, is clocked at 1GHz (GPU) / 6Gbps (Memory).

According the Unigine Heaven test, the new Radeon HD 7790 cards perform just as you would expect--they outpace the Radeon HD 7770 but trail the Radeon HD 7850. Compared to NVIDIA's offerings, the Radeon HD 7790 cards finish in front of the GeForce GTX 650 Ti but don't come close to the GeForce GTX 660 here.

I think it's also worth mentioning that the 7850 is a quite excellent overclocker. At stock I think it's definitely not worth the extra $30, but once overclocking is taken into account, if you can afford the $30 you are crazy not to spend it (assuming you are comfortable with overclocking of course).

I have to agree with you. Im running a MSI 7850 and the first thing I did was overclock it and it runs great. I actually used BF3, Far cry 3, and Metro 2033 as a bench to gauge about how my computer runs vs others. It does really well. The 7790 might be the more affordable option but like you said spending the extra few dollars or waiting till one goes on sale makes it worth it. Only advantage I see with the 7790 is newer architecture.

Good reviews about new AMD Radeon 7790. I like it and that one is perfet for anyone who need bit better performance on D11 games.

I think it's performance is right where it should be as a 7790. There is still room for a 7830 if AMD feels it's necessary.

Solid performance her for the price.  What's interesting is that this is a new GPU for AMD.  Wondering if they'll be buffing out the high end soon!

I completely agree.  I saw last night that this was a new GPU, and considering the performance they were able to put out with this low end budget card, i'm really excited to see what's next.

Also wondering what the response will be from mean green.

I don't know about team green, but I think along with a 7830, there might be a 7890 and a 7930, plus 7990 based on this chip.

I have been Looking for a reasonable upgrade to my graphics cards and this fits the bill quite nicely

Geez, my video card is so outdated. I use a Radeon HD4650. Aside from letting me play most games at a lower resolution and medium settings, all it really allows me to do is watch Blu Ray movies on my computer. I seriously wish I could afford to upgrade but with 2 kids and another on the way, it's probably going to be at least another 5 years or so til I can upgrade. It would be so wonderful to win some sort of gaming computer giveaway. I've put all of my money over the last 6 years into my family. It would be great if some sort of higher power looked upon me with favor and chose me to win a gaming PC. ;-)
