Sapphire Radeon HD 4670 512MB

On the backside of the graphics card the four screws are visible that hold the GPU heatsink in place along with the four remaining Hynix memory ICs. The PCB on the Sapphire Radeon HD 4670 is blue, compared to the reference version being red. The Radeon HD 4670 graphics card requires no external PCI Express power connector.

Two DVI and one TV connector makeup the outputs on the Radeon HD 4670. However, Sapphire does include a DVI to HDMI adapter (with 7.1 channel audio support) and DVI to VGA adapter.

Below is a photograph comparing the Sapphire Radeon HD 4670 512MB to the previously reviewed Sapphire Radeon HD 3650 512MB graphics card. As you can see, both graphics cards are similar but the RV730XT is just a few millimeters longer.
