AMD has just dropped us word of their latest graphics card release, the ATI Radeon HD 4890, which they’re claiming is the most powerful graphics processor in the world.

The beast runs at 850MHz, has 1.36 TeraFLOPs of processing power, as well as 1GB of GDDR5 memory and the functionality to cram four of these things in the same machine, using ATI’s Crossfire technology.

It’s notably faster than its predecessor, the HD4870, but slower than the dual core X2 variant. Pricing reflects that, with the card retailing between £185 and £200. It’s not a massive leap, just an evolution of existing cards, but it’s certainly a solid upgrade if you’re running a graphics card that’s a couple of years old.
