With last week’s surprising release of the HD4850, ATI has come back into the fold as a price/performance leader in the graphics marketplace. The HD4850 was a success if nothing else in that it forced the prices of the 9800GTX to lower in relation to the prices before the launch and is an excellent card in its own right. ATI’s HD4850 changed the video card game in that the market for cards under $200 is defined by higher performance and was the first TeraFLOP video card to hit the market. Today, ATI has launched their second strike in the battle against their arch-nemesis NVIDIA, the HD4870. This is the bigger brother to the HD4850 and I’ll cover the specifications and performance of the new card in this review. ATI was kind enough to send a retail 4870 box from Visiontek, an ATI manufacturer that has been making ATI cards for several years now after splitting off from manufacturing NVIDIA cards in the past and then reemerging onto the scene.
