The Radeon 4850 features a 625 MHz core clock and GDDR3 clock in excess of 2000MHz. Corporate documentation explains that the 480 stream processors on the RV770 processor offer considerable enhancements over the 320 stream processors found in the RV670 core, though AMD memos reveal little about how this is accomplished.
AMD partners claim the new card will not compete against the $600 GTX 200 just announced yesterday. Instead, AMD pits the Radeon 4850 against the recently re-priced NVIDIA GeForce 9800 GTX. Distributors claim the 4850 will see prices as low as $199 at launch -- well under the $299 MSRP for GeForce 9800 GTX. More expensive versions of RV770 will feature HDMI, audio pass-through and possibly the fabled Qimonda GDDR5 memory.
