Sapphire debuts fastest Radeon HD 4670

Sapphire has just made the Radeon HD 4670 faster.

The twist is an interesting one - replacing the GDDR3 memory with faster, more power efficient GDDR4. While the GPU speed remains fixed at 750MHz, the 512MB of GDDR4 runs at 2,200MHz, 200MHz faster than the GDDR3 reference models.

The card also offers a 128-bit memory interface, 320 Stream Processors and comes equipped with D-Sub, DVI and HDMI connectors. The eagle-eyed out there will alos notice the custom cooler with Sapphire claim has a noise output of less than 20 dBA.
