Sapphire and other board partners are now shipping R580 based Radeons

ATI today announced its new Radeon X1900 series of graphics cards. The chips are built on a 90 nanometer process and feature a whopping 384 million transistors. The X1900XT and X1900 Crossfire Edition share core/mem clock speeds of 625MHz/725MHz while the X1900XTX clocks in at 650MHz/775MHz. All other core features are shared among the three cards including 48 shader units, 256-bit memory interface, 512MB of memory and support for DX9 SM 3.0.

We have already given you a little preview of what the Radeon X1900XT can do, and it's no slouch in the benchmark arena. Seeing as how this is launch day, AnandTech, Beyond3DBjorn3D, Hard|OCPHot Hardware, Legit Reviews and t-break are just a few of the many sites that have reviewed ATI's new R580 architecture. Here's a little of what AnandTech had to say about ATI's new cards:

The numbers really do speak for themselves: the X1900XTX is an incredible part. In the end, the difference in performance between the X1900XT and XTX versions was so small that it's hard for us to see how anyone could justify spending another hundred dollars to have someone at a factory eek out that extra little bit of performance. ATI's justification for the X1900 XTX is that it is a pre-overclocked X1900 XT with a $100 manufacturers stamp of approval.

Sapphire has also announced three new R580 based video cards today and are shipping now (hopefully this means no more paper launches for ATI). You can see its product offerings on the right. Alongside, PowerColor has also announced availability of its X1900XTX series which offers a lifetime warranty for US customers.
