AMD company presented the Radeon HD 5970 card with two RV870 graphics chips, each of which contains 1600 shader. Because they operate at a frequency 725 MHz, the new card can achieve theoretical performance of 4.64 trillion floating point operations per second (TFlop / s) at single precision. By contrast, the double-precision Radeon HD 5970 graphics card as the first one breaks a barrier TeraFLOPS (1.088 TFlop / s).

On each of Shading GPU cores are arranged in 20 SIMD units consisting of 16 sets of five pieces. For each SIMD unit is also included a quad cluster texture, so the Radeon HD 5970 has a total of 2 x 80 texture units. Furthermore, compared with the model of Radeon HD 5870 doubled the number of raster operations - now it's 2 x 32 piece. GDDR5 memory with a capacity of 2 x 1 GB works with a frequency of 2000 MHz (Write Clock) and communicates with the RV870 chips using 256-bit bus, so the total transfer speed reaches 256 GB / s.
However, due to the fact that for processing graphic data must be permanently stored in the memory of the two chips, the efficiency we have only 1 GB of graphics memory. According to AMD, the power Radeon HD 5970 in the so-called. organic mode is 42 watts, which is very little like the graphics card with two GPU units. Fan test our reference model generated from a desktop background noise of a magnitude 0.5 sona. When operating a photo-realistic 3D scenes, the volume has already reached 1.7 sona, and the test was unbearable Furmark sona 2.7. According to data at maximum load the AMD Radeon HD 5970 uses up 294 watts. For this reason, the manufacturer uses a six-and ośmiopinowe outlet. The length of the card is 31 inches, so it does not fit into some covers.

In the first tests in accordance with DirectX 11 ATI Radeon HD 5970 model left behind with the two flagship Nvidia GPUs - the GeForce GTX 295 If, for example, the card HD 5970 was able to handle the game Crysis at a resolution of 1920 × 1080 and a double anti-aliasing at a speed of 56 frames per second (fps), it has been the GeForce GTX 295 with identical settings, only 38 fps. Connectors via two Dual-Link DVI and one slot Mini DisplayPort card Radeon HD 5970 will handle up to three monitors. Additionally, the main processor UVD2 assisted when playing movies in high definition.

ATI Radeon HD 5970 is expected to cost around 500 euros, but can be problems with their purchase. Finally, AMD is unable to produce even the series, announced in September 5800 a sufficient amount of HD RV870 chips, which are also used in the latest dual-GPU card.
