Today AMD released their second generation DirectX 11 video card with the Radeon HD 6800 series. The Radeon HD 6800 series consists of the Radeon HD 6850 and Radeon HD 6870 video cards and we have an in-depth review of them for you today. We also run them both in CrossFire to see how they scale and do all the usual tests that we throw at new video cards!
The AMD Radeon HD 6870 and Radeon HD 6850 proved to be two very solid performing mainstream video cards from what we saw in our initial testing with them. These cards are officially AMD's second generation DirectX 11 video card series, which is impressive as NVIDIA still has not released all of their first generation cards yet. When AMD designed the Radeon HD 6800 'Barts' series of GPUs they wanted to have Radeon HD 5800-class performance, but optimize the GPU to lower power use and the price tag. The cards do in fact have Radeon HD 5800-class performance in general and we saw much better power efficiency from the cards. This was done by lower the transistor count from 2.15 billion to 1.7 billion and as a result the die size went from 334mm2 to just 255mm2. Since both the Radeon HD 5800 and 6800 series are built by TSMC on the 40nm process we can see that AMD really cleaned things up inside the core and tuned this GPU for efficiency.
