New ATI Radeon HD 3850 and HD 3870

Last month AMD introduced the ATI Radeon HD 3800 series as “enthusiast gaming performance for the masses” through the Radeon HD 3850 and Radeon HD 3870, which are both sub-$250 graphics cards. While rudimentary, the Catalyst 7.11 Linux driver (also released last month), supports these two RV670 GPUs with better support coming through the Catalyst 7.12 Linux driver this month. To see how well these two PCI Express 2.0 graphics cards are able to perform under Linux, ASUS had sent out their EAH3850 TOP and EAH3870 TOP. We have tested both of these graphics cards using Ubuntu 7.10 and have compared the results to other products using the fglrx driver, including the ATI Radeon HD 2900XT 512MB. These are the world’s first Linux benchmarks of these new mainstream ATI graphics processors.

The ATI Radeon HD 3850 and 3870 are designed to be affordable GPUs and direct competition for NVIDIA’s recently released GeForce 8800GT, which we should be showcasing here under Linux shortly. These two ATI graphics cards use the RV670 core and are built using a 55nm TSMC process, which results in a smaller die size and a more energy efficient graphics processor. However, as this is an “RV” GPU, it does have a reduction in memory bandwidth and the internal ring bus compared to the flagship Radeon HD 2900XT.
