We checked out the new Sapphire Radeon HD 4850 X2 card and done some quick benchmarks on it using an Intel X58 platform with Core i7 processor. The cooler casing looks pretty nice and heatsinks beneath looks much like the Intel reference cooler. The air is drawn in by the dual fans and exhaust out from the top of the card, there is a hole at the top side of the cooler. This card is clocked at 625MHz for the core, a 1886MHz for the memories and has twice 800 stream processors. The card scores great, considering the fact that it has two RV770 GPU's on the same PCB, and it definitely looks great. This should bring some great extra performance in a single board product. - VR-Zone

Sapphire Radeon HD 4850 X2 Dual-GPU Card Preview

Several European retailers have jumped the gun and listed Sapphire's Radeon HD 4850 X2 card. The card packs 2GB of memory and it's clocked at 625MHz for the core and 1886MHz for the memory. It's not a reference design, as you can see by the dual fan coolers. The only trouble with it is that it's currently priced at Radeon HD 4870 X2 levels. The cheapest list price is $375, while the greedier retailers are going overboard with a plus $425 price tag. The cheapest Radeon HD 4870 X2 in Europe currently sell for $399. Of course, this is the initial launch pricing and you should probably expect it to and up near the $300 mark.
