|Up until at least March of 2007, the spearhead of the ATI Radeon HD 2900-family is the upcoming ATI Radeon HD 2900 XTX. This model is the big daddy of AMD’s DirectX 10 lineup, poised to take on NVIDIA’s GeForce 8800 GTX and upcoming 8800 Ultra. |
ATI Radeon HD 2900 XTX video cards feature 1GB of GDDR4 video memory, besting the GeForce 8800 GTX’s 768MB of GDDR3 video memory. GPU manufacturers often wait to set the exact clock frequencies of bins until just weeks before launch. Our Radeon HD 2900 XTX sample was released to board partners in the second week of April, features memory clocked at 2.02 GHz and a core clock of 750 MHz.
Physically, the Radeon HD 2900 XTX core is identical to the Radeon HD 2900 XT core. Both feature 320 stream processors, but the XTX differs by bringing GDDR4 to the package.
