Dual Radeon HD 4870 X2’s get Vantaged
AMD?s team in Austin managed to use two R700 dual-GPU graphic cards (four RV770 chips) to get a score of X12515. This was done with four GPUs, while Nvidia uses three GTX280 boards to achieve a similar score. The R700 boards were clocked at 778 MHz, while the GDDR5 memory was clocked at 980 MHz QDR (that’s 3920 “MHz”, or just 3.92 GigaTransfers/sec), we were told. This brought the total on-board video bandwidth to an impressive 250.8 GB/s.
R700 boards are planned for introduction within the next seven weeks and if we trust our sources, then we should expect the Phenom 9950 in a similar timeframe. The 790GX chipset will ship with two new Southbridge chips – the SB700 and SB750 will also arrive in time for these new products. So, we are taking note: AMD will have an overclockable graphics card, an overclockable processor and an overclocker-friendly chipset.
