Mainstream Attack - The ATI Radeon HD 5770


The Cards

The HIS Radeon HD 5770

As is the case with early releases, the HIS Radeon HD 5770 comes with ATI's reference cooler and PCB design. The design of the cooler follows that of the Radeon HD 5870, with two vents at the top end which helps suck in cool air to blow over the core. The HIS card also has ATI's reference clock speeds, which means 850MHz at the core and 4800 MHz DDR at the memory.

The HIS Radeon HD 5770 comes bundled with a free copy of Dirt 2, which can be redeemed when the game is released in December later this year.

The HIS card comes with ATI's reference cooler and PCB design.

The PowerColor Radeon HD 5770

Like the HIS card, the PowerColor Radeon HD 5770 also sports ATI's reference cooler and PCB design. As such, the two cards look identical except for the stickers which the respective vendors have pasted on them. Expect performance to be the same too, because the PowerColor Radeon HD 5770 also sports ATI's reference clock speeds.

The PowerColor Radeon HD 5770 comes in a nice compact package, and the cover features their new warrior mascot.

The PowerColor features ATI's reference designs, and as such, looks exactly identical to HIS's offering.

Here's what else you can expect from reference design Radeon HD 5770 cards:

The Radeon HD 5770 features ATI's Eyefinity technology and comes with two DVI, a single HDMI port and a DisplayPort. It can drive up to three monitors with the DisplayPort and any combination of DVI and HDMI ports.

The Radeon HD 5770 requires a single 6-pin PCIe power connector. It is hidden in the vents under the cooler casing.

The two card are using Hynix H5GQ1H24AFR GDDR5 memory which are capable of 7 GigaTransfers/second.
