ATI Radeon HD 3870 X2 reviewed

By on January 27, 2008, 11:38 PM
AMD has officially launched their new high-end flagship graphics card today and this one has a pair of graphics processors on a single PCB. The Radeon HD 3870 X2 was codenamed R680 throughout its development. Although that codename implies the card is powered by a new GPU, it is not.

The Radeon HD 3870 X2 is instead powered by a pair of RV670 GPUs linked together on a single PCB by a PCI Express fan-out switch. In essence, the Radeon HD 3870 X2 is “CrossFire on a card” but with a small boost in clock speed for each GPU as well.

Reviews: Hothardware, Anandtech, Hardocp.
Expect TechSpot's own take on the Radeon HD 3870 X2 later this week. Unfortunately we were unable to secure a card earlier.

Why GDDR3 over GDDR4 though? I thought that would have been ATi AMD's selling point maybe a dual GPU is, but this card would have such powerful memory at 1GB GDDR4 rather than 1800Mhz it would be around 2000Mhz, imagine through crossfire quad GPU's and a Core2Quad 4GB of RAM, 2GB graphics memory and Win Vista ultimate 64bit hmmm power.

Cutting costs probably... remember Nvidia will soon launch their own dual GPU (in a single board) product, so AMD has better staying within a competitive pricing range. I assume makers will be able to use higher clocked memory in the near future and charge a bit extra.
