ATI Radeon HD 4850 and 4870

The announcement of the ATI Radeon HD 4800 architecture has enabled AMD’s graphics department to claim technological superiority after a long while.

The developer has proved he is not only alive and well but has plenty of resources to develop best-in-class graphics solutions.

As a dramatic change in the company’s development strategy, ATI now focuses on creating mainstream rather than ultra-performance top-class GPUs.

The RV770 processor, the heart of the new ATI Radeon HD 4800 series, has been created according to this new strategy.

Within ATI’s approach, increasing the new chip’s performance must be accompanied with a meticulous optimization of its architecture.

It may sound paradoxical, but developing a best-in-class mainstream GPU that would combine high performance with low power consumption is a more difficult task than developing a new monster of the ultra-high-end class.
