Shortly after last month's release of the Radeon HD 4890, which set a new performance record for ATI as the fastest single GPU to date, the company has another new graphics card for us today, this time targeting the under $ 100 market .
The new Radeon HD 4770 is the world's first 40 nm graphics processing unit. While not designed for speed records like the flagship 4890, the 4770 is meant to deliver the best possible value in a neat, affordable package.
It is common practice for both ATI and Nvidia to do the initial migration to a new design process with a mid-range or even lower-priced GPU in order to have time for improvements before moving them over to high-performance parts. The Radeon HD 4770 is not an easy proposition, however, as the GPU has 826 million transistor counts, or just 14% fewer than the Radeon HD 4890, ATI's most complex ATI GPU to date.
Since we often enjoy testing the latest and greatest products like the Radeon HD 4890, it's easy to forget that the demand for graphics cards priced at over $ 300 is relatively low. While ownership gives the achievement crown boastful rights, it is likely more successful in providing the best mainstream solutions possible.
As already mentioned, ATI will aim for the price range of 100 US dollars with the Radeon HD 4770 and will thus be in direct competition with the Nvidia GeForce 9800 GT. AMD claims that the GeForce 9800 GT ($ 115) delivers 5.1 GFLOPS per dollar based on current prices, while the Radeon HD 4770 delivers an incredible 8.8 GFLOPS. In addition, the Radeon HD 4770 achieves 12.0 GFLOPS per watt, while the GeForce 9800 GT only offers 4.8 GFLOPS.
But of course they would never say anything else, so of course we will examine how these two graphics cards compare in real-world scenarios. Before we look at the numbers, we'll also take a closer look at the Radeon HD 4770's card design …
