If there is one thing we enjoy doing here at OC3D, besides bringing you the best content, it's going a bit mad. We love just trying to push the envelope in a 'let's pretend money was no object' kinda way.
We've done MARS 2 SLI. We've done Quadfire HD7970. Now we're back with Quadfire HD7950. Of course gaming with this kind of setup is pointless, so we're focussing on the three big benchmarks, 3D Mark Vantage, 3D Mark 11 and Unigine Heaven.
You know all about the cards from our other reviews, so let's just get on with the results. If you need to talk about how much your jaw hurts after it hitting the desk go to our forums.
4x HD7950 (Sapphire, HIS Digital, XFX and AMD)
Catalyst HD7970 Drivers 11.12
Intel Core i7-3960X @ 4GHz
ASUS Rampage IV Extreme
Windows 7 Ultimate x64
Ahh the joys of four pulsating GPUs all ready for a good thrashing. Overclocked to 1050MHz on the core, we're ready to rumble.
3D Mark Vantage
Talk about on the leading edge of what is possible. The HD7950 QF is only 2600 points behind the HD7970 QF in the all-important P-Score of 3D Mark Vantage, giving us a mighty score of 62559.
Amazing how close the HD7950 QF setup gets to the HD7970 QF one on Extreme with only 3000 X Marks in it, and the MARS 2 SLI rig is a whopping 7000 points further back.
3D Mark 11
In the underwater world of the 3D Mark 11 benchmark, the HD7950s beat out the HD7970s in P Score. Only 500 points, but given that they are a 1000 Stream Processors short, it's a mighty fine result. The intensity of the Extreme preset just squeaks out a larger score from the big brother, but it's still a damn good score, and still over 10000.
Once again the HD7950 Quadfire shows how close the card is when compared to its big brother. We saw in all our single card testing that a HD7950 can run a HD7970 very near, and in Quadfire the story is the same. Barely a handful of frames between the two setups. Mightily impressive.
