Last month we published several leaked details about AMD's next-generation graphics card lineup, but as we get closer to the launch the folks over at TG Daily have managed to get the scoop on AMD's launch plan details for its upcoming HD 4800 series of graphics cards.

Contrary to last month's rumors, the series will apparently debut in mid-June after all in the form of the Radeon 4850, which will boast 512 MB of GDDR3 memory, single-slot cooling, CrossFireX support, and a price tag between $189 and $219. This will be followed by the dual-slot cooled GDDR5 bearing HD 4870 and the HD 4870 X2 in mid-July, both priced between $249 and $279. You can check out the rest of the report for more information on features, specs and performance claims regarding these cards.
