ATI to launch four Radeon X1900 cards?

ATI is planning to introduce four R580 GPUs to completely replace the current R520 (Radeon X1800) lineup, The Inq writes.

These new GPUs will be branded as Radeon X1900XL, X1900XT and X1900XT CrossFire Edition. Although there's also a rumour of another naming convention, with the names X1900XT ("T" instead of an "L"), X1900XTX (The Boss, King, Macho) and X1900XTX CrossFire Edition.

Besides this plain vanilla 3D boards, ATI will also rollout the refresh of All-in-Wonder product, which actually - was the reference board ATI is actually using to demonstrate the R580 chip to its valuable customers and partners. We haven't been able to confirm the clockspeeds of the product, but since we learned that new All-in-Wonder demo boards come with 1.26ns GDDR-3 memory, it isn't too hard to figure that possible memory clock for X1900XL(T?) is 1.5 GHz, giving out 48GB/s of bandwidth. That would be clear 16 GB/s wider than current AiW model, based on R520XL chip.

The Radeon X1900 is expected to arrive on January 24, 2006.
