Sapphire's Radeon HD 4730 makes use of a 750MHz core clock speed on its reduced RV770 core, coupled with 512MB of GDDR5 clocked at 900MHz.

In keeping with its choice of GPU core, the Radeon HD 4730 features the same PCB length as other RV770-based parts. The usual pair of CrossFire inter-GPU connectors are present on the board, while power is provided by two six-pin PCI Express power connectors. Sapphire have strapped their own dual-slot cooler to the board - A cooling solution that we've seen on a couple of other Sapphire graphics boards in the past.
