Considering that we've already seen AMD's ATI Radeon HD 4850 benchmarked
, it's not like we really needed some official verbiage to cement our belief that the unit was real. Nevertheless, said verbiage certainly doesn't hurt, and that's precisely what's been delivered this morning. The HD 4850 is a single-slot PCIe 2.0 card featuring 512MB of DDR3 RAM, a 625MHz clock speed, 993MHz memory speed, 480 stream processors and support for CrossFireX
/ DirectX 10.1. We're also told that at least Diamond Multimedia's HD 4850 is available as we speak from a number of fine retailers, thus we presume everyone else's version of the card shouldn't be too far behind.
