Right off the assembly line
AMD finally released a competitor to nVidia’s GeForce 8800 family, ATI Radeon HD 2900 XT (formerly known by its codename, R600).
The New ATI Radeon HD 2900 XT runs at 740 MHz and access its 512 MB GDDR3 memory at 1.65 GHz (825 MHz x 2), using a new 512-bit memory interface, with boosts the memory maximum theoretical transfer rate to 105.6 GB/s – Radeon X1950 XTX has a memory maximum transfer rate of 64 GB/s and GeForce 8800 GTX, of 86.4 GB/s, but the new GeForce 8800 Ultra reaches 103.6 GB/s.
Since it is based on Shader 4.0 (DirectX 10), this video card uses a unified shader processing architecture, i.e. instead of having separated units for processing pixel shader, vertex shader, physics and geometry, it has several generic units, called “stream processors”. This model has 320 processing units, against 128 on GeForce 8800 GTX and Ultra.
The Radeon HD 2900 XT requires two extra power connectors – as its chip is still manufactured under 80 nm process, it has a typical power consumption of 215 W and AMD recommends at least a 500 W power supply for this baby (750 W if in CrossFire configuration) – however AMD certified some 400 W units to be used with this new video card.
