Sapphire HD 4830 - ATI Graphics Card Review

This is part 1 of a 2 part review of Sapphire's recent addtion to the HD 4000 series graphics cards, brings us the HD 4830. It is a mainstream card that by looking at the specs alone suggest great performance possibilities for the exceptional price point compared to other higher end cards.

The HD 4830 uses the same architecture of Radeon HD 4850 and Radeon HD 4870, but with 640 graphics processors instead of 800 and up from other models. Clocks are also different with the HD 4830 running at 575Mhz which is a little less than the HD 4850 but more than the GeForce nVidia 9800 GT.
