Had your eyes on the world's first DirectX 11 compliant graphics card? Your wait is now over with the launch of Advanced Micro Device's ATI Radeon HD 5800 Series graphics card series. Reportedly, the HD 5800 series is one of the world's most powerful GPU series ever created, supporting the newest generation DirectX 11. According to AMD, its newest video card series boast up to 2.72 TeraFLOPS of compute power, effectively doubling the value consumers can expect of their graphics purchases, delivering twice the performance-per-dollar of previous generations of graphics products. Currently the firm unveiled two cards under HD 5800 series: the ATI Radeon HD 5870 and the ATI Radeon HD 5850, each with 1GB GDDR5 memory.

With the ATI Radeon HD 5800 series of graphics cards, PC users can expand their computing experience with ATI Eyefinity multi-display technology, accelerate their computing experience with ATI Stream technology, and dominate the competition with superior gaming performance and full support of Microsoft DirectX 11, making it a “must-have” consumer purchase just in time for Microsoft Windows 7 operating system.

Both of them features 2.15 billion 40nm transistors, 1600 stream processing units (1440 units in case of HD 5850), GDDR5 interface with 153.6 GB/sec of memory bandwidth, PCI Express 2.1 x16 bus interface, DirectX 11 support, Shader Model 5.0, OpenGL 3.2 support.

The HD 5870 boast of engine clock speed of 850 MHz, processing power (single precision) of 2.72 TeraFLOPS, processing power (double precision) of 544 GigaFLOPS and 1.2GHz memory clock speed.

On the other hand the HD 5850 provides engine clock speed of 725 MHz, processing power (single precision) of 2.09 TeraFLOPS, processing power (double precision) of 418 GigaFLOPS and 1GHz memory clock speed.
