After two of its partners broke the news prematurely, AMD has finally given the Radeon HD 2900 Pro an official introduction. The card is launching in 1GB and 512MB variants, which both feature 320 stream processors and a 512-bit memory bus. The 512MB model is clocked at 600MHz with 800MHz GDDR3 memory, and an AMD spokeswoman tells us the 1GB variant runs at 742MHz with 800MHz GDDR4 RAM.
For reference, AMD's Radeon HD 2900 XT is clocked at 742MHz and has 512MB of 825MHz DDR3, with the same 320 stream processor count and 512-bit memory bus width. The Radeon HD 2900 XT 1GB, meanwhile, has 1GB of 1000MHz GDDR4 memory.
AMD says the new Radeon HD 2900 Pro 512MB is launching at $249, and that the 1GB flavor is rolling out at a pricier $299. Of course, even $299 is considerably cheaper than even the most affordable Radeon HD 2900 XT listed on our price search engine, which still costs $383.99.
