When ATI presented the new generation of graphics cards based on the RV770 chip, first model was their Radeon HD 4850. This model despite few problems, became mega popular when it comes to the Radeon HD 4800 series of graphics cards that now consists out of so many models. Although it was first presented, the Radeon HD 4850 was far from the top performance model. Nevertheless even today its sale rates are high because its main advantage was price. For relatively a small amount of currency you will get GPU with 800 stream processors that was enough to run all new games.

The problems that the Radeon HD 4850 had were mostly the consequence of its single slot cooling solution that was used and that looked from day one, that it was mounted because someone said that a single slot cooler should be mounted without taking into account what engineers said. Of course, other manufacturers recognized this problem and almost all of them used custom cooling solution on their Radeon HD 4850 models. An unexpected twist in this story is that its main adversary comes from the same team. Now ATI presented the first GPU made in 40nm manufacturing process with idea to test new manufacturing process.

As we already mentioned the Radeon HD 4770 is based on new technology but is it enough to achieve almost the same performance levels as its older brother remains to be seen.
