Elite Bastards posted a review on the Sapphire Radeon HD 4650 HDMI 512MB video card
Generally speaking, Sapphire have stuck with AMD's reference Radeon HD 4650 design here, employing the same small, single-slot cooling solution and utilising the standard 600MHz core and 700MHz memory clock speeds to boot.Sapphire Radeon HD 4650 HDMI 512MB Video Card Review
Due to that small cooler, most of the memory modules on the board aren't actively cooled, although this isn't really a big deal for this level of card. As you'd expect, no external power is required for the Radeon HD 4650 HDMI, with the PCI Express slot capable of handling this board's requirements. The PCB is also bereft of any CrossFire inter-GPU connectors, thus limiting CrossFire connectivity to communication of data between GPUs over the PCI Express bus.
