Innovative video cards only come along every once in a while. When ATI launched the HD 4870 last year, they took the lead in the price/performance category of video cards. Their HD 4870 had a less expensive stablemate in the form of the Radeon HD 4850. This had the same specifications in terms of SPs, ROPs and other specs but was clocked slightly lower and used GDDR3 memory instead of GDDR5 on the HD 4870.
Late last year ATI released the Radeon HD 4870 x2 to compete with the GeForce GTX280 cards from NVIDIA. This combined two HD 4870s on a single PCB, improving performance versus a single chipped card. Board manufacturers like Sapphire have gone a different route. The HD 4850 was a great card for its price why not combines two of them on a single card like the HD 4870 x2 using the HD 4850 chip? Sapphire is a manufacturer of ATI based video cards and today's review is on the HD 4850 x2 video card from them.
