AMD Unveils Latest Dual-Chip Graphics Card

Advanced Micro Devices (NYSE: AMD) on Tuesday introduced a dual-processor graphics card for gamers that the company claims is capable of more than 2 trillion operations a second.

Along with the ATI Radeon HD 4870 X2, AMD unveiled the slower HD 4850 X2. Both cards, which slip into a PCIe slot on the PC's motherboard, comprise two HD 4800 series GPUs. The HD 4870 X2 delivers 2.4 teraflops, or about three times the processing power as a single-GPU HD 4870 card. A teraflop equals a trillion floating point operations per second.

In addition, the card includes 2 GB of ultra-high bandwidth GDDR5 memory, and its GPUs are clocked at 750 MHz.
