AMD's second generation DirectX 11 Radeon HD 6800 is not completely re-elaborate graphics processor. Instead, AMD has the ATI Radeon HD 5800 predecessor trimmed for efficiency and added new features.

Drastic changes in the graphics chip architecture, The Radeon HD 6800 now stand, the five video outputs in the eye: the two mini-display port and HDMI DVI and once in the current version 1.4a. Maximum of five outputs can be on the six screens simultaneously connect up to.

Made possible by the two mini-display port, version 1.2, the pairing of up to three monitors in a row allow it. However, the controller can display still the HDMI and two DVI outputs drive the same, since the active-automatically a DVI-HDMI output is disabled.

The Series 6800er AMD can still at TSMC in a 40-nanometer process to manufacture. Compared to previous 5800 graphics processor, the Radeon HD 6800 but failed by about 20 percent less. The chip area is now 334 instead of only 225 square millimeters and the number of transistors is reduced from about 2.2 to 1.7 billion .

In spite of this Radeon HD 6800 performance level of his predecessor reach - and that with restrained power hungry. Reason for the increase in efficiency: According to AMD, intermediate calculations buffers of the graphics processor and effectively utilized the various shaders using a second execution unit (dispatcher) is better also.

In addition to the tessellation unit works efficiently go by polygon number of objects dynamically to adjust the viewing distance. The AMD Radeon HD 6850 is a very good value for money and provides a real alternative to graphics cards with the Nvidia chip Geforce GTX 460 768MB
