Diamond Radeon HD 4870 X2 XOC Review

We like a good combo here at HotHardware, and we have a new one to add to the list. Right up there with peanut butter and jelly, Mario and Luigi, milk and cookies, we'd like to add dual GPUs and factory overclocks. If you are a regular reader, you probably already know we are fans of dual GPU video cards, and we have a strong affinity for factory overclocked video cards as well. And when a company combines the two, that's just fine in our book.

So, it goes without saying that we were excited to check out Diamond's overclocked Radeon HD 4870 X2 XOC graphics card (model number: 4870X2PE52GXOC). As you probably already know, the Radeon HD 4870 X2 employs two RV770 GPUs, each of which is complemented by 1GB of GDDR5 memory (for a total of 2GB frame buffer memory). The reference GPU clock speed for the 4870 X2 is 750 MHz, and the reference memory speed is 900 MHz. We are happy to report that Diamond boosted the XOC's clocks to 800 MHz and 950 MHz, respectively, making this one of the fastest 4870 X2 cards we've seen in the HotHardware labs. Speaking of the labs, we took the XOC for a spin with our benchmark suite and pitted it against a reference 4870 X2, an NVIDIA GeForce GTX 285, an NVIDIA GeForce GTX 295, and a pair of GeForce GTX 285s in SLI. Read on to see how the XOC fared in the comparison.
