AMD reclaims performance crown with HD 4870 X2
The new Radeon HD 4870 X2 proved to be a top performer, whether running in a single-card configuration or in a dual-card, four-GPU, CrossFireX configuration. 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.
Make no mistake, the new Radeon HD 4870 X2 marks ATI’s return to the top of the 3D graphics food chain. It took a few years, but through steady improvements in multi-GPU software support, and a new strategy regarding the design and manufacture of high-end graphics cards that utilizes two mid-sized chips in lieu of a single monolithic one, AMD was able to produce a graphics card capable of outpacing the best NVIDIA currently has to offer.
