HIS Radeon HD 6990 4GB Review

31 thumbs up

How We Configured Our Test Systems: We tested the graphics cards in this article on a Gigabyte GA-EX58-UD5 motherboard powered by a Core i7 980X six-core processor and 6GB of OCZ DDR3-1333 RAM. The first thing we did when configuring the test system was enter the system BIOS and set all values to their "optimized" or "high performance" default settings. Then we manually configured the memory timings (DDR3-1333, CAS 7) and disabled any integrated peripherals that wouldn't be put to use. 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 the necessary drivers, games, and benchmark applications.

Unigine Heaven v2.5 Benchmark
Pseudo-DirectX 11 Gaming


Unigine Heaven

Unigine's Heaven Benchmark v2.5 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.

The HIS Radoen HD 6990 performs at essentially the exact same level as the reference Radeon HD 6990 card in this benchmark, but neither can keep pace with the GeForce GTX 590. NVIDIA currently has a distinct advantage in terms of geometry and tessellation, and it shows in a benchmark like this that uses a ton of tessellation at the options we used for testing.

"I just wanna know if AMD has fix their driver problems with Crysis 2 running on the 6990. especially quad crossfire, or dual 6990. Oh yeah , good luck finding one of these, newegg cant keep up with the demand."

OMG 4GB of Memory? I just looked up the price and even though it's expensive hit me with those benchmarks so I can dream Marco :)

That is one beast of a card thanks for the review. I could imagine that this thing puts off a lot of heat and the fact that it is blowing some of it back into the system properly placed fans are a must as mentioned in the article.

Actually it's 2GBs per GPU but with the way Crossfire works (rendering an alternating frame rather then the same frame for each card.) You actually get 4GBs instead of 2GBs.

Clever eh?

I was surprised it did not pull away more at the higher resolutions as 4GB is nothing to slouch at.

None the less it's still a beast of a card and remains on top.

yep this card is big powerful and generates quite a bit of heat . anyone considering one of these would likely have the high-end chassis fans PSU $$ etc to consider a GPU as this..Always great to see the best & appreciate the great review,benchmarks evaluation and insights..

You see the brilliance of the new naming scheme. 6990 implies that this is the pinnacle of the ATI 6xxx series. Hmmm...or maybe not, there's always 6995...

The box looks like the same size as my 8800, Better make sure you have room in your case:P

What a beauty, too bad the noise on this thing is outrageous, but I guess thats what happens when you cram 2 graphics card GPU's in a case that usually fits only 1, im sure that fean bears a huge workload keeping those puppies cool.

Anybody know what a single GPU in the 6990 is equivalent too, or what crossfire rig is on par with a single 6990?

I'm guessing a single GPU in the 6990 is equivilant to the 6970 and the 6970 (or 6950) crossfire is equivilant to a single 6990.

And also, I'm hoping that Artic Cooling releases a cooler for the 6990 as they did for the 5970. The cooler they released kept the two GPU's cool and it also sounded nearly quiet as well.
