AMD R600 Architecture and GPU Analysis

 

ATI Radeon HD 2900 XT – AMD's long awaited R600 DX10 GPU arrives

 

"AMD's Radeon HD 2900 XT is going to cost between US$350 - US$399, closer to the latter in most places. That makes it at least US$150 cheaper than most GeForce 8800 GTX 768MB cards. Sure, Nvidia's 8800 GTX green champ won most of our tests in the 1280 x 1024 to 1920 x 1200 range but not by as bigger margins as we expected. What is interesting are our results at the 2560 x 1600 resolution – both products have their share of driver issues (which need to be sorted out quickly!) but from our testing at this point in time, the HD 2900 XT makes a really good showing at the 2560 x 1600 resolution. In games like Prey, Company of Heroes and Far Cry, the more expensive 8800 GTX really only has a small lead over the XT. In real-world terms, both offer basically about the same level of game play experience in terms of smoothness and we put that down to the massive 106GB/s of memory bandwidth from the R600, which is able to be properly utilized at this ultra-high resolution. With some overclocking of the core and memory, the HD 2900 XT could probably match or better the more expensive 8800 GTX and that is with 256MB less memory. This in turn tells us that the engineers of the R600, while slow and indecisive, were smart and produced a GPU which is very efficient – but at the right settings."

elmor overclocks Radeon HD 2900 XT CrossFire - New 3DMark 05 world record

 

"Overclocker elmor has now shown that Radeon HD 2900 XT CrossFire is the king of 3DMark 05. It wasn't long ago when Kinc managed to set a new single-card 3DMark 05 world record, but elmor has now broken the overall world record with a CrossFire system, using only air cooling for the cards! While the CPU was enjoying some cool liquid nitrogen, the Radeon HD 2900 XTs was still sweating with the stock coolers. Kinc has earlier posted a number of results in the forum that showed what kind of potential there is with these cards and elmor has now given us a taste of what is about to come."
