ATI Radeon HD 5970 Dual-GPU Powerhouse Review
Introduction and Specifications
It began with the RV670, which powered the single-GPU based Radeon HD 3870 and dual-GPU Radeon HD 3870 X2--hence the X2. Then came the RV770, which powered the Radeon HD 4870 and eventually the Radeon HD 4870 X2. The strategy has obviously paid off, as AMD is once again a price/performance leader in the GPU space, after some not-so-great performances like the R600, better known as the Radeon HD 2900 XT. Knowing their strategy, it should almost come as no surprise that the graphics card we'll be showing you today, the Radeon HD 5970, has come to fruition. Although it doesn't follow the same naming convention as AMD's previous dual-GPU powered cards, the Radeon HD 5970 is nonetheless powered by a pair of ATI "Cypress" Radeon HD 5800 series GPUs, linked together on a single PCB by a PCI Express bridge, very much like previous X2 iterations.
Considering the fact that the Radeon HD 5870 is undeniably the fastest single-GPU powered graphics card currently on the market, this dual-GPU powered Radeon HD 5970 should offer performance that completely outclasses any other single graphics card on the market currently. In addition to killer performance, the Radeon HD 5970 also boasts all of the same features of the Radeon HD 5800 series, like full DirectX 11 support, ATI Eyefinity support, top-notch image quality and power efficiency.
We've got a Radeon HD 5970 in house, in full retail trim, courtesy of HIS that we've run through and array of benchmark tests. Read on to see how AMD's new flagship fares in light of competing single and dual-GPU powered solutions...

AMD's release schedule with their latest barrage of DirectX 11 capable GPUs is outlined on the slide above. Of course, a lot of groundwork had to be laid over the years before the company could produce this line-up of products. As the above list of specifications and features show, the new Radeon HD 5970 is quite advanced in comparison to other current GPU products. But the chip does leverage technologies already implemented in previously released GPUs, so it's not all new. As such, we'd recommend perusing some recent HotHardware articles to brush up on a few of the technologies and features employed by the new Radeon HD 5970...
