AMD is getting ready to update their graphics card lineup with the introduction of the RV790-based Radeon HD 4890 which we recently received and were able to confirm the specs. While no pricing information has been confirmed yet, the card is expected to debut on April 9 for about $250, and as mentioned over the weekend Nvidia plans to fire back that same day with the GeForce GTX 275.


According to reports, the new card is going to have the same amount of stream processors as the GTX 280 and GTX 285 (240) but it will have 896MB GDDR3 on a 448-bit memory interface. It is built around the 55nm G200b GPU and will boast a core speed of 633MHz as well as 1404MHz for the Shader and 1161MHz for the memory. Likewise, the company is aiming for a $229 to $279 price range for the card. It should be interesting to see how these two perform when they hit the bench we already have a Radeon HD 4890 in our hands and are expecting to get the GTX 275 soon.
