'Radeon HD 4800' graphics board pictured

AMD has been eerily quiet about its next-generation graphics processors, but according to rumors we've heard over the past few weeks, next-gen Radeons are on the way nonetheless. In fact, a report posted on a German website last month said Radeon HD 4000 graphics cards are scheduled for June.

The report might have only been a rumor, but the folks at VR-Zone have spotted a picture that suggests AMD may indeed be pretty far along on its upcoming GPUs. The picture, which was originally posted by Chinese site ChipHell, shows what's said to be an RV770 graphics board. The PCB doesn't look too different from existing RV670 boards used by Radeon HD 3870 and Radeon HD 3870 cards, but there are a few differences, namely in the placement of the memory chips and the PCI Express power connector. The area on the board that's meant to play host to the actual RV770 GPU is empty, however.

According to VR-Zone, RV770 graphics processors will be clocked "above 1GHz" and will be paired with GDDR5 memory. Reportedly, yields of RV770 chips are high, and the current GPU revision (A11) is the same one AMD will end up using on retail cards when they hit stores. This information checks out with Hartware.de's report, which said the forthcoming RV770-based Radeon HD 4870 would run at up to 1050MHz and would feature 1GB of 1100MHz GDDR5 memory.
