ATI HD 5870 Vs HD 5850 Vs HD 5830 Reviews & Benchmark

Here is a comparative review I select it for you from some of the best reviewer websites between the latest ATI HD 5000 series , the ATI HD 5870 , ATI HD 5850 and the ATI HD 5830 .

HD 5800 series:

Codenamed Cypress, the Radeon HD 5800 series was announced on September 23, 2009. Products included Radeon HD 5850 and Radeon HD 5870. The launching model of Radeon HD 5870 can support 3 display outputs at most. An Eyefinity edition of Radeon HD 5870, with 2 GiB GDDR5 memory, supporting 6 simultaneous displays to be connected to the mini DisplayPort outputs, was released recently. The Radeon HD 5870 has 1600 usable stream cores, while the Radeon HD 5850 has 1,440 usable stream cores, as 160 out of the 1,600 total cores are disabled during product binning which detects potentially defective areas of the chip. A Radeon HD 5830 was released on February 25, 2010. The Radeon HD 5830 has 1,120 usable stream cores and a standard core clock of 800 MHz.
