Hd 5850 For Mac



The ATI Mobility Radeon HD 5850 is a high-end DirectX 11-capable graphics card for notebooks by AMD based on the desktop HD 5770 (RV840) chipset. Essentially, the HD5850 is a Mobility Radeon HD 5870 that has been underclocked by about 11 percent. In contrast to the HD 5870, the 5850 is sometimes equipped with slow DDR3 graphics memory.


Futuremark released 3DMark Vantage, on April 28, 2008. It is a benchmark based upon DirectX 10, and therefore will only run under Windows Vista (Service Pack 1 is stated as a requirement) and Windows 7. For today we will be testing focusing on both Performance and Extreme resolutions. The default setting that most people use to compare their scores world wide is 12801024 which is referred to as the Performance level. As the HIS 5850 iCooler V Turbo is one of the higher performing cards today, we will also focus on the Extreme settings. This setting uses the resolution of 19201200 and puts far more strain on the GPU then the default settings.


Both of our cards scored reasonably well at both resolutions we used for our testing. The numbers clearly show that the Extreme preset is by far the more demanding test. The higher clock speed of the HIS 5850 iCooler V gave it the edge in all tests when we compare it against the reference clocked 5850. 350c69d7ab
