The Radeon HD 4870 X2 arrives today, two RV770 GPUs running in tandem, for what is effectively a Radeon HD 4870 CrossFire configuration on a single PCB. Expect Radeon HD 4870 X2 cards to be available immediately for about $549:
In the games and applications we tested, the Radeon HD 4870 X2 outperformed every other single graphics card, including the GeForce GTX 280. Generally speaking, the 4870 X2 was on-par with or marginally faster than a Radeon HD 4870 CrossFire setup and somewhat faster than a GeForce GTX 260 SLI configuration in most benchmarks, although the GTX 260 SLI rig did catch up with it a couple of times. Depending on how well the Radeon HD 4870 X2 CrossFireX configuration scaled, it too was one of the fastest multi-GPU configurations available, but a pair or trio of GeForce GTX 280 cards were faster in a few instances.
Welcome back to ultra high-end AMD. It’s obvious you have worked hard, and your efforts have paid off. The Radeon HD 4870 X2 is a 3D graphics tour de force.
