HIS’ HD 7950 "V2"

HIS’ HD 7950 "v2"



Shortly before this review was supposed to go live, a nondescript UPS shipment held a bit of a surprise: what looked to be a custom cooled HD 7950 from HIS. We just couldn’t pass up the opportunity to include it so fast forward to the Temperature Testing section where we run its unique heatsink through our usual battery of tests.

It should also be noted that this design may very well become the de facto standard for less expensive “Version B” HD 7950 cards. We’ve already seen some preliminary designs from other board partners with very similar –if not identical- layouts. So get used to this design because there may be quite a few cards with this same unique cooling solution.

Speaking of unique, this is one of the first times we have seen a somewhat custom cooler that so closely reflects the reference card's design. The similarity really is remarkable which is why we believe this is actually a version that AMD's board partners will be using in place of the higher end heatsink. The rest of the card –from its length to component layout- is a spitting image of the original version though due to HIS’ move away from a vapor chamber-equipped cooler, the entire affair is a good bit lighter. We should also mention that the VRM components have been slightly changed but still consist of a fairly robust 6+1 layout.


HIS has decided to use a custom blue PCB for this card which has the ability to use a 6-pin / 8-pin power layout so we’d hazard a guess that its used for their HD 7970 as well. The colour choice may turn some people off since a black PCB coupled with a black and red heatsink shroud does look great but for most the change won’t make a difference. Otherwise, all of the usual HD 7950 features like dual 6-pin power connectors, a BIOS switch and two Crossfire interconnects are present and accounted for.

The backplate also uses the reference layout with a pair of mini DisplayPort connectors along with outputs for HDMI 1.4 and DVI. Unfortunately, HIS DOES NOT include any adaptors so if you want to run more than two monitors from their HD 7950, additional cables will need to be purchased.

3DMark 11 (DX11)

3DMark 11 (DX11)


3DMark 11 is the latest in a long line of synthetic benchmarking programs from the Futuremark Corporation. This is their first foray into the DX11 rendering field and the result is a program that incorporates all of the latest techniques into a stunning display of imagery. Tessellation, depth of field, HDR, OpenCL physics and many others are on display here. In the benchmarks below we have included the results (at default settings) for both the Performance and Extreme presets.

Battlefield 3 (DX11)


For this benchmark, we used a sequence from the Rock and Hard Place mission. The results may seem lower than normal and this is due to the fact that after playing through the game multiple times, this one are was found to be the most demanding on the GPU. As with all of the tests, we try to find a worst case scenario in order to ensure a given card can properly play through the whole game instead of just a “typical” section.

Crysis 2 (DX11)


Crysis 2 with the DX11 and Texture Package installed not only looks great but it is a strain on any GPU. For this benchmark, we used a classic runthrough which includes far views, explosions, combat and close-in knifing; basically every hallmark of gameplay.

Deus Ex: Human Revolution (DX11)

Deus Ex: Human Revolution (DX11)


Deus Ex: Human Revolution may not be the hardest game for today’s high end gaming rigs to render. While the game mostly takes place indoors, it is the few outdoor areas that put additional strain on graphics cards. So for this test, we use one of the more involved outdoor sections: the Sharif Manufacturing Loading Docks.

Dirt 3 (DX11)

Dirt 3 (DX11)


Dirt 3 isn’t all that much different from its predecessor but the developers have added a few more visual touches but boost image quality. In this case, we used the Michigan Rally track since it features some of the hardest to render features of the game: expansive vistas, water, dirt effects, trees and many other items.

For this test we use a walkthrough and combat scene from The Bridge level which starts at the beginning of the level and lasts for about 3 minutes of walking, running and combat. Famerates are measured with FRAPS and Advanced PhysX is turned off.

Shogun 2: Total War (DX11)

Shogun 2: Total War (DX11)


Due to its very nature, Shogun 2 is a tough game to benchamark since the in-game tool doesn’t accurately convey an in-game experience. So we took a pre-recorded battle which pits three large armies against one another and includes camera zooms, fog, gun smoke and other items. Using a pre-recorded sequence also effectively removes the CPU from the equation since it doesn’t have to process AI.

The Witcher 2 (DX9)

The Witcher 2 (DX9)


The Witcher 2 may be a DX9 based game but its graphics quality is beyond reproach. In this benchmark we take an area out of The Kayran mission and include one of the toughest effects the graphics engine has in store for the GPU: rain. Throughout this sequence, rain plays a large part but explosions, combat and even some sun shafts are included as well.
