AMD's R700 to embrace both GDDR3 & GDDR5

If everything goes smooth, AMD will unleash its dual-GPU R700 boards before this cruel summer ends. Hot on the heels of the Radeon HD 4850 and 4870 cards, R700 will feature two RV770 GPUs on one board and it seems that, unlike what happened with earlier this year, both the HD 4850 X2 and HD 4870 X2 come pretty much simultaneously.

The HD 4850 X2 and HD 4870 X2 will naturally come with similar features like PCI-Express 2.0, DirectX 10.1 support, 960 Stream Processors and 2x256-bit memory interfaces but will differ through working frequencies and the memory used. The Radeon HD 4870 X2 will go for GDDR5 with clocks likely to be lower than those of the single-GPU-ed HD 4870 while the HD 4850 X2 will utilize GDDR3 memory. No word on actual clocks though. We'll live.
