Radeon HD 4000-series revised launch dates
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.
Specifications from Diamond Multimedia marketing material claim the new Radeon will require a 450 Watt power supply for single card support; or 550 Watt power for CrossFire mode.
