HIS Radeon HD 7770 GHz edition review

Back ins February AMD released new GPU's under codename Cape Verde, and the graphics cards deriving from that GPU family where the Radeon HD 7750 and 7770 One GHz edition. This is not a refresh it really is a completely new GPU based of the same technology family that powers the R7900 series, the GCN architecture.

And that's interesting, as with less shader processors AMD will make this product a notch faster. They benefit from the GCN architecture but also have a trump card at hand, as this is the first ever reference card that is clocked at 1 GHz - hence AMD will give all these cards a 'GHz edition' extension. See, the 28nm node allows them to place a good 1.5 billion transistors onto the GPU 123 mm2 die, and that should make the card a good 25% faster opposed to the popular R5770.

AMD  has been focusing on three primary features and key selling points ever since the series 5000 products have been released. First off, the new graphics adapters are of course DirectX 11 ready. With Windows 7 and Vista being DX11 ready all we need are some games to take advantage of DirectCompute, multi-threading, Hardware Tessellation and new shader 5.0 extensions.

Another big feature of the product that you already learned about is of course Eyefinity, the ability to connect many monitors (depending on AIC/AIB choices in outputs) to your videocard and use it in a desktop environment, or to create an incredibly wide monitor resolution to play games in. The third big and prominent feature is of course performance for money.

HIS recently released an updated Radeon HD 7770 1GHz edition with their own custom model. They use their own custom 4-layer PCB and equipped it with a dual slot all silent cooling solution.

Over the next few pages we'll walk you through the standard reference technology and then place our focus on the HIS Radeon HD 7770 GHz edition. But not before you have had a peek alright. Next page please.
