ATI Radeon HD5770 ConclusionThe performance of the HD5770 is pretty amazing, considering the modest looking hardware resources that make it all possible. One way of showing this objectively is to look at the power required to deliver the performance. The 5770 offers roughly the same performance as an HD4870 for approximately half the power, and that's at full load, without all the power saving tricks that are used to get the idle power below 20 watts. Performance is more than just frames-per-second, though; the ability to run 2-3 monitors with Full ATI EyeFinity Support counts, too. Plus, we've been measuring performance with Beta drivers. If you've read some of my recent video card reviews, you've got a better understanding of why driver performance on launch day is not a good measure of the final product. So, while the raw performance numbers are good enough for the target price point today, I predict even better things to come for both price and performance.
The appearance of the product itself is both retro and futuristic at once. The red hood scoops may have been lampooned as Batmobile wannabees, but for the most part, the design is clean and sleek; a perfect canvas for the partners to display their best artwork. There may be some non-reference designs in the works, but the usual motivation for that effort is usually improving the thermal performance. I don't see that as a real necessity with this card/chip combo. The reference design has plenty of cooling capacity for the tiny Juniper GPU. The build quality of the Radeon 5770 is a bit hard to assess. I've already noted some unique characteristics of the engineering sample I received, like DIP switches that don't appear on production versions, so I hesitate to pass judgment on something that a consumer will never see. Overall, the parts were all high quality, and while the PC board may have had a few rough edges, the cooler section was manufactured and assembled perfectly. The features of the HD5770 are also amazing, having been carried over in full measure from the HD5800 series: DirectX 11, Full ATI Eyefinity Support, ATI Stream Technology Support, DirectCompute 11 and OpenCL Support, HDMI 1.3 with Dolby True HD and DTS Master Audio. We've barely scratched the surface in this review, focusing almost exclusively on gaming performance, but the card has other uses as well. As of October 13, at launch, ATI is aiming at a price point of $159 for the HD5770. A quick look at Newegg shows this to be right in the mix between the HD4870 and the GTX260-216. ATI priced this card right in the middle of the pack, performance-wise, but it has advanced features that the other cards can't match. Many ATI partners will also be bundling the card with a free download of DiRT 2, the latest version of an action-packed favorite, in order to showcase the new DirectX 11 capability. Once prices come down ten or twenty dollars, this card is going to be a screaming value. The ATI Radeon HD5770 earns a Golden Tachometer Award, because it's a game-changing package for the middle ground. Perfectly timed to match up with the launch of Windows 7 and its DirectX 11 interface, it's the card to get if you are putting a system together in its price range. Pros:
