Sapphire HD7950 Overlock Edition Crossfire Review

We are using the latest version of Sapphire’s TriXX tool for overclocking today. This has proven to work great with all AMD discrete graphics hardware.

Both of the cards we received today overclocked to over 1,200mhz with some core voltage increases. One card achieved 1,209mhz and the other 1,215mhz. Memory performance on both cards was limited to around 1530mhz. These are sizeable overclocks and superior to the other samples we received today.

The massive overclock from both cards reaps huge rewards in 3dMark 11, increasing the score from 12,976 points to 15,406 points. Well ahead of the HD7970 Crossfire configuration (at reference speeds). These cards have clearly massive headroom.

  1. Awesome, if its £360 thats £130 less than their 7970….

  2. 1,200mhz? thats insane. worth the money for that alone!

  3. Looks like this is the new ‘to buy’ card, like the previous 6950 which could be unlocked.

  4. Why are all the companies supplying them in such low states of clock? 1000mhz seems easy and would get them sales.

  5. ARIA Dont sell this one. just the 800mhz version. Its 360. I think this will be closer to 400. Are they any different, better batch or hand picked maybe?

  6. XFX cooler looks better, this is very plastickly. I would wait on the better Toxic edition which will probably be out in a month, with even higher clocks and premium capacitors etc.
