Powered by the Juniper XT chip, the Radeon HD 5770 sits just under ATI's powerful Cypress-powered Radeon HD 5800 series and is ATI's answer to the mid to high-end market.
When we reviewed it back in October, we were a tad disappointed to find that while it is largely similar to the older RV770 and RV790 chips- in that it has the same number of stream processors, texture mapping units and raster operating units - it has to make do with a narrower 128-bit memory bus interface, which inevitably hampered performance. In the end, we found that the new Radeon HD 5770 is a tad slower than even the old Radeon HD 4870.
Nevertheless, the new Juniper XT chip does bring about improvements such as support for DirectX 11, EyeFinity, and much lower operating temperatures and power draw. And truth be told, the Radeon HD 5770 is only a smidge slower than the Radeon HD 4870. These are reasons enough for an upgrade for those who needed performance characteristics of the 4800 series but with the improved characteristics of the 5700 series.
The MSI R5770 Hawk and PowerColor HD 5770 PCS+ are two of the first customized and factory-overclocked Radeon HD 5770 cards to hit the market.
So if you are looking to upgrade to the latest Radeon HD 5770, we are pleased to say that vendors today are slowly releasing their customized editions on the Radeon HD 5770. And to help you make an informed decision, we've round up two of the latest Radeon HD 5770 cards from MSI and PowerColor for a head-to-head no holds barred showdown.
