Radeon HD 2900 PRO
Radeon HD 2900 Pro graphics cards based on the chip codenamed R600 Pro fit under 150W TDP
The Radeon HD 2900 Pro graphics processor runs at 600 MHz and contains 160 stream processors. For comparison, in the Radeon HD 2900 XT there are twice as many of them, and in the Radeon HD 2600 a little less - 120. Unfortunately, there are only eight rasterization units, however, the number of texture units has not changed in relation to the older Radeon HD 2900 XT.
The Radeon HD 2900 Pro was designed for the mid-range and was faster than almost any video card based on the GeForce 8600 GTS.
