At English speaking resource hardocp.com published the results of testing the newest video ATI Radeon HD 4870 X2, also known as R700, based on a pair of RV770 graphics chips from ATI / AMD. Immediately specify that an engineering sample and tested in serial ATI Radeon HD 4870 X2, may be used updated versions BIOS and drivers. But despite all this, the new test results “Double” card from ATI / AMD pleasantly surprised.

Recall that ATI / AMD embarked on the path different from NVIDIA - they have failed to develop new roads and high-performance graphics chip, but simply issued a video card with a pair of inexpensive RV770 working in the mode of CrossFire. Also in the HD 4870 X2 uses an updated bridge between graphics processors to achieve the speed of data exchange between GPU about 20 Gb / s and a hardware switch for PCI Express with support for PCI Express 2.0. Very large copper radiator contributes to a better cooling two hot chips ATI Radeon HD 4870 X2 and makes it much harder than the GTX 280.

Testing ATI Radeon HD 4870 X2 conducted in parallel with the BFG GeForce GTX 280, using a driver ForceWare 177.41. Most tests conducted with high resolution and maximum load on the video card. In the tests used gaming applications such as Crysis from EA and Age of Conan: Hyborian Adventures, as well as novelty was tested at capturing high-resolution screenshots of games Call of Duty 4 and Age of Conan.

In gaming benchmarks ATI Radeon HD 4870 X2 revealed itself as not good, especially when using high-level anti-aliasing. In Crysis confidently worked with the new mode settings “high” on solving 1920×1200 points, that is a very good result for such a demanding game like Crysis. In standby mode CrossFireX pair of new products showed excellent results during the regime of preferences “very high” on all the same permission 1920×1200 points. Only on resolving points of a pair of 2560×1600 HD 4870 X2 beginning to surrender, but it may have been caused by engineering software and BIOS.

In Age of Conan HD 4870 X2 also confident spared GeForce GTX 280 in normal mode and standby CrossFireX. At the big break permits increased even more dramatically.

All these results showed only significant superiority of hardware ATI Radeon HD 4870 H2 over the GeForce GTX 280, possibly using an updated version of the software (software and BIOS) the difference will become even more pronounced. And all this with the declared value at the producer level with its main competitor - GeForce GTX 280. The official publication of retail sales is scheduled for late summer this year.
