AMD's upcoming RV790-based Radeon HD 4890 graphics card continues to make its appearance on the Internet, showing up in one form or another, before the Sunnyvale, California-based graphics maker had a chance to officially unveil it. According to the latest details, the company's upcoming 55nm-based single-GPU graphics card will
be capable of providing its users with an impressive performance level, one that will likely place it as a direct competitor to NVIDIA's current GeForce GTX 285 graphics card.
The guys over at ocheaven managed to score some screenshots of the 3DMark 06 and 3DMark Vantage results of the new Radeon card. As you can see in the pictures below, the RV790 GPU is good for an impressive score of 16096 and P10996, in 3DMark 06 and 3DMark Vantage, respectively. Unfortunately, we don't know what graphics drivers were used for the new card, but these scores could go higher with some improved drivers.
Aside from the early revealed 3DMark scores, the new card is expected to boast a core speed of 850MHz and an impressive memory clock of 3800MHz. The card should come with 1GB of GDDR5 memory and should be equipped with a 55nm GPU and 965 million transistors. It is meant to allow AMD to gain a better market share in the enthusiast and high-performance segment, where the company has no competitor for the newly released GeForce GTX 285 and GTX 295 cards from NVIDIA.
Unfortunately we still have no details on an official release date, but according to earlier reports, AMD's new single-GPU flagship model should make its debut sometime in early April. With the new card, there have been rumors about Advanced Micro Devices planning a new dual-GPU model based on the new RV790 GPU. This will potentially be titled Radeon HD 4890 X2 and compete with NVIDIA's GTX 295.
