>> PowerColor Radeon HD 4850 512MB and CrossFire performance review
As we mentioned in our introduction, PowerColor's take on the Radeon HD 4850 uses AMD's reference clock speeds, making for a 625MHz core and 993MHz GDDR3 memory clock.
The board also sports a reference, single-slot cooler, while featuring all of the other usual accoutrements of your typical AMD graphics board. CrossFire support is available in the usual fashion via a pair of inter-GPU connectors, and power is provided to the board through a six-pin PCI Express power connector.
