PowerColor HD4850 Review

Lowest Prices


So how will ATI's new weapon stand up? To test the HD4850, I will be running a series of video benchmarks to measure frames per second and scoring based on how well the card performs. In addition, I will pit the card up against other current video cards on the market to compare performance. All hardware will be set to stock speeds, voltages, and timings to keep any variables from interfering with the testing and throwing off the scores. For a head to head comparison of the latest and greatest, I am including the new Nvidia GTX 280 to see how the HD4850 stacks up with other cards released at the same time. I am also including an HD3850 to see the improvements from last generation to this generation.


Comparison Video Cards:



Overclocked settings:

  • PowerColor HD4850 645/1045MHz

During testing, I was having issues with the card overheating. Due to this overheating, the overclocking suffered and I was not able to get what I expected. The final speeds were 645MHz on the core and 1045MHz on the memory (2090MHz effective), and these are the speeds that I will run the overclocking tests on. With proper cooling, I feel that this card could go further, and I plan on re-visiting the overclocking tests on the HD4850 in the future, when aftermarket cooling solutions become available.
