The advantages the HIS Radeon HD 7770 iCooler offers over the reference AMD design aren't immediately obvious, subtle are the changes made. The tweaked fan and shroud effectively increase the cooling capacity and reduce gaming load noise while being cost effective due to the minimal change from reference design. The colors and styling are conservative; well suited to mainstream desktops.

The perfect HD 7770 would feature a redesigned PCB with shorter length, higher default clocks, more power phases and tweaked Powertune limits to make the most of the 150W electrical potential of the card. This would all significantly add cost to a low margin part; especially one that needs to stay close to reference SEP or it's not attractive. The HIS Radeon HD 7770 is little high over the $109USD price point reference designs are selling for; it should be a little more competitive without relying on rebates although the game bundle is a nice touch even if it isn't a triple-A title, it's a nice value add.

We see some generally good scaling with Crossfire, but 1GB VRAM stops a pair of 7770s being able to really work for triple display gaming; if you're willing to forgo AA then you could give it a shot for a low cost, low power multi-screen rig. We were expecting to see micro-stutter problems with our uneven clocked cards, but stutter or judder wasn't perceptible in any of our interactive tests. Starting from scratch if you were considering dual 7770's, you'd be better off looking at a 7850 2GB or last gen HD 6950 for your $200USD unless the size of the cards is an issue.

The default clocks are clearly only a starting point for the Radeon HD 7770, and our sample unlocked more potential than the engineering sample we received at launch from AMD but as always, overclocking is never guaranteed and should always be considered a free performance boost - if you're happy with voiding the warranty. HIS offer a 2 year limited warranty in North America, and we'd really like to see the iCooler bumping up the engine and memory clocks out of the box. The overall value of the HIS Radeon HD 7770 iCooler is fair and we award 4 stars.
