Thread: Sapphire Radeon HD 5850 graphics card

The Sapphire Radeon HD 5850 is based on the DirectX 11 graphics chip AMD ATI Radeon HD 5870 Unlike the top graphics chip, the 5870 version works 5850 with a nearly 15 percent reduced to chip clock (725 instead of 850 MHz). Also of GDDR5 graphics memory of the Sapphire Radeon HD 5850 runs at a lower clock speed of 1000 instead of 1200 MHz (minus 17 percent). AMD has cut red tape in the streaming processors (SP) was used also in comparison with top model 5870 with 1600 of these processing units are the Radeon HD 5850 only 1440 SP active.



The graphics card design of the Sapphire Radeon HD 5850 differs from the Sapphire Radeon HD 5870: Instead of 27 is the 5850 model only 24 inches long. Moreover, the two 6-pin PCI Express power connectors are moved from the side back into the right vent. Is identical, however the overall height - the graphics card occupies two slot plates - and the fan, fan noise with a sone in the desktop mode and 2.1 Sone in 3D mode is somewhat below the 5870 peak model. Remained the same at the Sapphire Radeon HD 5850 is the graphics memory capacity of one gigabyte and the 256-bit wide interface.

Despite the compromise on the clock speeds and processing units developed the Sapphire Radeon HD 5850 test, a powerful 3D performance. In the ultimate test with the game Crysis the card provided at 1920 x 1200 pixels and the highest image quality just yet fluid 29 frames / s. the Sapphire Radeon HD 5850 to date in the seventh-fastest card Crysis benchmark. Compared with the 5870 model of the Sapphire Radeon HD 5850 was 15 percent slower. Compared to the Nvidia competition, the Radeon HD 5850 in Crysis placed between the GeForce GTX 285 and 295
