9 Radeon HD 6850 Compared

jmke · 13th April 2011, 16:35

The Radeon HD 6850s are based on Barts, a GPU which is a sort of low-cost version of Cypress, used in the Radeon HD 5800s. A few small improvements have however been made, especially in terms of tessellation performance and support for DisplayPort 1.2 and MVC hardware decoding, the format used for 3D Blu-rays.

Barts is made up of 224 vec5 processing units (1120 ‘cores’) divided into 14 blocks, two of which are disabled in the version used for the Radeon HD 6850, bringing the number of vec5 processing units down to 192 (960 ‘cores’). The processing units are supplied by a 256-bit GDDR5 memory controlller, which has been simplified to reduce costs and which hasn’t been designed to clock very high.

In the end the Asus Radeon HD 6850 DirectCU is the card that’s probably closest to the very good reference card (not on sale) and which is the model we advise you to look at first. With a very slight factory overclocking, designed simply to justify the use of an extra logo on the box, this Radeon HD 6850 is well cooled, quiet and the manufacturing quality is better than average.

Just bought Radeon HD 6870

, from Asus
