The HD 6870 DiRT 3 edition is a beast. While we did not particularly love DiRT 3 as a game, a free copy is more than welcome for fans to experience the power of the AMD Sapphire Radeon HD 6870 DiRT 3 edition. While we already reviewed the HD 6870 base samples through AMD, and then add-in contact reviews including Sapphire’s 6870 line, this special OCed edition was worth a look for the people who have been e-mailing regarding Sapphire products on top of VisionTek lines.
First off, the packaging itself is beautiful. Sapphire at this point has shown us that they create packaging that is amazing in terms of their quality of build and the fan structure. We also popped it open for good measure, and loved the consistency of the thermal compound, which most video cards kind of skim (NVIDIA sometimes).
The OC comes at 920MHz which is 20MHz up on the default 900MHz HD 6870 clock while the clock rate of the RAM remains the same at 4200 QDR (DDR on 2 channel bits). Admittedly, there is not much to say about this card that has not necessarily been said. Is it worth the slight increase in price? This is really up to someone to decide. From a mathematical point of speaking, higher Hz means higher clock frequencies. 20Hz can make all the difference every second for every minute (1800Hz/min). Should consumers want something that is quiet while being a little faster, this is definitely a step up from a normal 6870 even if not by a lot.
