AMD recently released their Raden HD 4650 and Radeon HD 4670 cards which are based on the AMD RV730 graphics processor. The cards are targeted at the sub-$100 segment and which is also where the NVIDIA GeForce 9600 GT and GeForce 9600 GSO are positioned. While other board partners have designed their own PCB's to reduce cost or optimize it to their own design goals, Sapphire has chosen to use ATI's reference board design. Unlike the reference design, the clock and memory speeds are increased to 650MHz and 1800MHz, far from the maximum as our overclocking tests will show later. This certainly should be a great card with a good price to performance ratio. - techPowerUpSapphire Radeon HD 4650 512MB OC Version Review (http://www.techpowerup.com/reviews/Sapphire/HD_4650_OC/)
