After months of delays and much anticipation, ATI has finally come up with the Radeon HD 2900 XT, a DirectX 10 capable GPU meant to compete with Nvidia"s GeForce 8 series, and the first big introduction in the PC enthusiast market since AMD acquired the company.
Today we have in our hands a Radeon HD 2900XT board, which is of course based on the R600 core using an 80nm design process. This version features just 512MB of onboard GDDR3 memory clocked at 1656MHz using a 512-bit wide memory bus. Combined with a core clock of 757MHz, the Radeon HD 2900XT can theoretically produce a memory bandwidth of 102.4GB/s, which is greater than that of the GeForce 8800 GTX.
