Last month, AMD released by far the world's fastest single-GPU graphics card, the Radeon HD 5870. A slightly watered-down version called the Radeon HD 5850 followed shortly afterwards. The latter has proven itself to be very competitive, only play second to its bigger brother and at just $ 260 it's hands down the best high-performance offering out there right now.
AMD continues the successful launch of its Radeon HD 5000 series and is now targeting the under $ 200 market. He hopes to keep the momentum going with the Radeon HD 5770 and 5750. Code-named Juniper XT and Juniper LE are the first to cost just $ 160, while the lower 5750 costs between $ 110 and $ 130 depending on the memory configuration.
We were particularly interested in the ATI Radeon HD 5770 as the last generation Radeon HD 4770 was one of our most popular budget graphics cards of all time. Although it was late in the game, it was rated "Outstanding" for its great performance and operational efficiency, making it the top choice in the $ 100 range. We certainly expect this new series to meet these standards.
Before we get into banking, however, there are a few things to consider about the Radeon HD 5770. First off, at $ 160, it's 38% cheaper than the Radeon HD 5850, but it also has 40% less memory bandwidth available. This is mainly due to the fact that the memory bus width is halved. The core configuration of the 5770 is also about 46% lighter and has fewer stream processor units, texture addressing and rasterization operator units.
With raw data only, we expect the Radeon HD 5770 to be around 40% slower than the Radeon HD 5850. In other words, the Radeon HD 5770 should work close to the former high-end 4870.
This should be good news for gamers looking for an inexpensive upgrade. However, it's not the previous generation Radeons that the 5770 has to worry about. The GeForce GTX 260 with a similar price competes. Despite the obvious drawbacks that this annual card brings with it, such as higher power consumption and lack of DirectX 11 support, the GeForce GTX 260 is still a very worthy competitor. How will the 5770 compare?
