The source reports some details of the chip ATI code-named Cypress, which is known as the RV870. The internal code name for this chip generation Evergreen, and this name represents all the chips for graphics cards ATI-generation DirectX 11. New high-performance chip is called the Radeon HD 5870, but the manufacturer plans to release two versions, one with 2GB of memory, and the other with 1GB. According to the source, these chips will be presented to the United States and in Europe on September 23. Manufacturer says that graphics chips have already been prepared, but AMD is still needed some time to debug the driver and the video card itself. Pity, but will have to wait a bit.

Chip Radeon HD 5870 is made on the basis of core RV870, it operates at a frequency 825MGts and has a 1600 shader, which is two times greater than that of RV770. Probably, the new chip will be twice faster than last year's RV770. The new chip has 2.1mlrd transistors, it is more than twice the number of transistors RV770, in which they "only" 956 million. HD 5870 uses GDDR5 memory at the frequency 1.3GGts (5.2GGts mode Quad) and can provide a throughput of more than 150Gb / s. Power consumption cards on this chip is 180W, and in idle mode it will consume just 27W, three times less than the HD 4870, consuming 90W.

Based on rough estimates of characteristics can be assumed that the Radeon HD 5870 may ultimately prove to be two times faster than the Radeon HD 4870. In any case, 60% performance increase can be expected with certainty.

As you know, the chip for the ATI Radeon HD 5850 is a slow and a little cut-down version of the chip Radeon HD 5870, and this slow chip has 1440 shaders and is clocked at 725MGts. This chip Radeon HD 5870 has shader 1600 and is clocked at 825MGts. The frequency of GDDR5 memory in the chip 5850 is 1000MHz, which is considerably less 1300MGts memory chip 5870, and as a result of memory bandwidth HD 5850 is 136Gb / s, however, is more than the HD 4870. Just as the Radeon HD 5870, HD 5850 will have 32 ROP, its maximum power consumption is 170W under load and 27W in idle mode.

Map, code-named R800, the one that AMD plans to launch under the brand Radeon HD 5870 X2, should appear in about a month after the release of single-chip version of the Radeon HD 5870, code-named Cypress. As in the case of HD 5870, Issue Radeon HD 5870 X2 is delayed not because of the chips, but because of the attendant problems.
