28 nm GCN (Graphic Core Next) Architecture
The new and 28nm GCN Architecture with more efficient process technology puts more transistors in less space, enabling a dramatic increase in Processing Power. Crank the settings, devastate your enemies and bear witness to absurdly high frame rates with AMD Radeon HD7000 series graphics card-DirectX 11 has never looked this good. Maximum setting and crazy performance shouldn’t be a compromise. The AMD Radeon HD7900 Series with the new 28 nm GCN Architecture assures that it’s not.

PCI Express 3.0
PCI-Express 3.0 delivers double the bandwidth per lane of PCIe Gen 2 for faster GPU (GPU communication-up to 16GB/sec in each direction), maximizing the performance from your GPU when paired with the latest platforms.

Question  Question by Mimi

would this card be better than a HD4870x2 when running crossfire?

Answer by Patrickc on Friday, June 15, 2012
2x 7770 should perform better than the 4870x2. You might be better off spending your money on a single 7850 though.

Question  Warranty with Sapphire by JES

Hello Sir,

First year is with us, 2 years after with Sapphire.

Thanks for your question.

Question  Screen Flicker. by RareSpoons

I upgraded my old 4870 to this a month ago, a great card at half the power/noise level. The only problem im having is im gettin alot of screen flicker? Be it games or not, could this be due to a faulty card or a driver issue? I've updated and reinstalled 12.3 multiple times with Driver Sweeper and still get this issue.


Answer by stewartz on Saturday, April 7, 2012
I would personally try reinstalling the original drivers and see if this fixes it, and if so then it sounds like a faulty driver install. If this still doesnt fix the problem then it could mean the card is faulty.

Question  CrossFire by darasza

Can I use two of them on this motherboard ASrock P67 Pro3 SE and is OCZ ModXtream 600w psu will be enough

Answer by stewartz on Thursday, April 5, 2012
You might get away with it, but I would personally recommend a 700W+ just to be on the safe side.
