Sapphire HD7950 Overlock Edition Crossfire Review

To test power consumption today we are using a Keithley Integra unit and we measure power consumption from the VGA card inputs, not the system wide drain. We measure results while gaming in Crysis Warhead and record the results.

In such an energy aware climate, AMD are making a big deal out of their new ‘ZeroCore Power’ technology. Many solutions today use power gating, clock gating and memory compression to reduce idle power requirements, but ZeroCore power technology can completely power down the core GPU while the rest of the system remains active.

Power consumption from a single card is good and in line with what we would expect from a HD7950, averaging 186 watts when gaming.

  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.
