Firing Squad writes: "It's been an extraordinary summer for ATI graphics. Without a doubt, their revolutionary RV7xx graphics architecture delivers an unprecedented level of performance per square millimeter. This allows cards like the Radeon 4850 and 4870 to compete very favorably with NVIDIA's GeForce 9800 GTX+ and GTX 260 GPUs despite their smaller die size: RV770 measures just 260 square millimeters versus GT200's 412 square millimeters.
With these cards competing favorably against NVIDIA in the mainstream graphics segment, and the Radeon HD 4870 X2 sitting as the king of the hill in the high-end graphics market as the world's fastest graphics card, tactically ATI's strategy now shifts to the budget segment of the graphics market. It's been said that ATI is aiming for 50% share of the discrete graphics market by the end of this year; in order to get there ATI has to win this crucial segment, as budget cards ship in far larger volumes than mainstream and high-end cards."
