DonanimHaber is reporting that Nvidia will introduce its dual-GPU card at the PAX East 2011 event, which kicks off March 11.
The new card, designated GTX 590, packs two GF110 cores on a single PCB, but we still don’t know the details. It should pack 3072MB of GDDR5 on a double 384-bit bus, but there is no word on the clocks yet. The biggest concern, of course, is power consumption. There’s a good chance the GTX 590 will be the hottest and hungriest card of all time.
AMD is also working on its HD 6990 Antilles board and it should launch at about the same time. It appears neither Nvidia nor AMD will showcase the new boards to the general public at CeBit, but they should show up a couple of weeks later nonetheless.
