Sapphire Radeon HD 7950 OverClock Edition review

The best graphics card on the market right now

TODO alt text

The benchmarks don't lie and show the Sapphire Radeon HD 7950 OverClock edition is only a fraction behind the vanilla Radeon HD 7970.

Thanks to the impressive overclocking potential within the Sapphire card, and the AMD Tahiti core in general, you can easily push the OverClock edition to the same performance levels as the HD 7970.

All of these benchmarks were run at 2560x1600, with the overclocking results taken at the relevant card's maximum achieved overclock.

There's little between them at the very top end of the OC tree.

The SAPPHIRE HD 7950 OC Edition, which is factory overclocked to 900Mhz and features SAPPHIRE's new dual-extractor technology - Dual-X - a highly efficient multi-heatpipe cooler with dual fans providing quiet and very cool operation during normal operating conditions, and superb cooling performance even under extreme load.
For enthusiasts wishing to maximise performance, a new version of the SAPPHIRE overclocking tool, TriXX supporting this latest generation of technology is available free to download from the SAPPHIRE website. TriXX allows tuning of GPU voltage as well as core and memory clocks, whilst continuously displaying temperature. Manual control of fan speed is supported, as well as user created fan profiles and the ability to save up to four different performance settings. Both of the SAPPHIRE HD 7950 models have a dual BIOS, allowing for further experimentation by the enthusiast. On the OC edition, the second BIOS is pre-programmed to allow a higher maximum overclock and more aggressive fan profile.
