We'd like to thank Unigine for helping us set up their benchmarks.

The card is factory-overclocked, but the extra 25 MHz do not provide any significant bonuses. To get the idea about card performance, you might as well take a look at the results of a regular Radeon HD 6850.

Final thoughts

We've recently switched to a simpler rating system and now we only have two of those: capability and usability. The capability rating compares each graphics card with GeForce GT 430 which is considered a baseline, or 100%. The rating is based on both synthetic and gaming results and shows, as the name implies, what a product is capable of.

The usability rating is obtained by dividing each card's capability rating by its price. It basically shows whether a given product is over or underpriced, considering what it can do, and thus how reasonable it is to buy it.

The complete ratings can be found in our i3Dspeed. Below are just the parts relevant to today's review.

Sorted by capability (high to low)

According to our results, Radeon HD 6850 outdoes GeForce GTX 460 in its immediate price range (about 170-175 USD).

Sorted by usability (high to low)

As you can see, Radeon HD 6850 is almost at the top of our usability rating and has a very attractive price/performance ratio.

Sapphire Vapor-X HD 6850 1GB GDDR5 has a quiet and very efficient cooler and comes with a nice package. Essentially, it has no drawbacks, although factory overclocking leaves much to be desired.
