HIS HD7950 Review
As with all of our GPU reviews from 2012 onwards we're using the X79 LGA2011 rig.
HIS Digital HD7950
Catalyst HD7970 Drivers 11.12
Intel Core i7-3960X @ 4GHz
ASUS Rampage IV Extreme
Windows 7 Ultimate x64
Just like its brother the HD7950 is a monster overclocker, easily capable of maxing the slider in Catalyst Control Center. It's not only the Core that can take a good overclock either, the Memory can be pushed way beyond stock.
Demonstrating that beliefs about the correct place to put a fan doesn't make us designers, the reference HD7950 is cooler than the HD7970 under load, but pretty toasty when idle.
