Conclusion: How to sum up this card? Overall it performed admirably in all tests and did so with surprisingly low noise. The Vapor-X cooling solution held true to its roots and kept the card both cooler and quieter than most other cooling solutions even when pushing the card to its maximum capabilities.
Pros: Awesome cooler (temperature and noise), Good performance even in Eyefinity, Effortless stock overclock
Cons: Failed Batman: Arkham City tests (likely an issue with only the review card), Cooler is too large to run more than two on a standard motherboard, Custom PCB requires custom water blocks for Tri/Quad CrossfireX, Price
Conclusion: Recent price cuts, free games, and driver-related improvements have brought AMD's Radeon HD 7950 back into serious contention for users looking for the best £250 graphics card on the market. Sweetening the deal that little bit more, AMD's providing more performance by way of a user-upgradeable vBIOS that increases the core clock from 800MHz to 850MHz, jumping up to 925MHz under the auspices of PowerTune with Boost.
Excerpt: It really feels like AMD are a little lost at the moment and don't know how to handle what NVIDIA are throwing at them. Normally you'd see a company take one of two approaches when it comes to combating a competitor. The first is you'd go and drop the price on your current video cards to bring them in at a stronger price point against the competition.
Conclusion: We tend to look at Sapphire cards more than any other brand on both the AMD and Nvidia front, and it’s great to see them keeping up with the market and doing something unique in the process, and that’s exactly what we have here with the 7950 OC Dual-X fleX. As the name suggests, we have a 7950, but we also have an OverClock Edition, with the Dual-X cooling solution with fleX technology, so why don’t we break it all down slightly.
Excerpt: The Flex Edition series from Sapphire has been around for a while now and we've seen a few models for fall under the series. The big feature that the Flex Edition video cards bring is the ability to have three DVI monitors running in Eyefinity mode. Normally you're restricted to two at most with the third being a DisplayPort based display.
Sapphire Radeon HD 7950 3GB DDR5 Flex Edition Video Card Review
Hi Tech Legion
11 June 2012
Summary: Synthetics -
Synthetic benchmarks showed very good scores. For 3DMark 11, the GPU score was 2452 with the 7950 Flex Edition. This is actually over 100 points from the previous OC edition I reviewed. Unigine had a FPS pf 43.5 and Tessmark gave a score of 4059.
DirectX 11 -
All of the DX11 games were set to their maximum settings possible. AvP had a very good 84.4 FPS. Battlefield, at ultra settings, was smooth at 45 FPS.
Cons: Dual-X Cooler, Stock Core Overclock, Flex Technology, Low Noise, Low Power, Better Further Overclocks, Eyefinity At Max Settings On Most Games
Summary: You could probably run this card with a good 500W power supply, or even a pair of them in CrossFireX with a good 700W unit. The Sapphire card costs a little less than the XFX card, idle power is a little lower, and Sapphire doesn’t skimp on the display adapters. That makes it a pretty good deal, given its overall performance level compared to the much hotter and more power-hungry GTX 580s.
Pros: Excellent performance for this price range; very power efficient; 900MHz core clock
Cons: Just a bit noisier than the 7970 (but much quieter than GTX 580s); slightly lower memory clock than the XFX model
Excerpt: At the launch of the new HD 7950 we checked out a pair of pre-overclocked Sapphire cards in CrossFire . Today we check out the other HD 7950 the company is offering and see how it goes with the latest WHQL driver from AMD which is the first official driver for the HD 7900 series.
