At CeBIT there was some discussion as to what the new high-end products from ATI will be like. ATI is working on a release for ASIC name RV790 for sure.  First off, everybody agrees .. there will be a release in April from ATI.

Based on the feedback we got back from AIBs it does look like there will be a card called ATI Radeon HD 4890 (a single GPU card). This card will be released to compete the GeForce GTX 260 (not the GTX 285). As it seems the two things different will be the frequencies of the GPU. Rumors are that 850 to 900 MHz is a possibility for the new RV790 GPU (4870 is clocked to 750 MHz). Secondly expect a memory frequency increase compared to the Radeon HD 4870.  Memory wise we expect a slight bump from 3600 MHz towards ~4000 MHz GDDR5.

Of course if you talk about RV790, the conversation quickly jumps towards a possible Ati Radeon HD 4890 X2, and as it seems ... it doesn't look like we'll be seeing a new X2 anytime soon based on RV790 as as released by ATI. Board partners are however free to build an X2 card, but the last time this happened that policy ended up to be a drama as Sapphire really was the only one offering a 4850 X2 board.

We expect an April release of Radeon HD 4890 with a sales price of roughly
