Sapphire HD4850 Dual Slot Heatsink Review

» Discuss this article (4)


At OverclockersClub.com, we use a set of benchmarks to stress the graphics card. We will use a series of newer gaming benchmarks, as well as some that are more seasoned, to show how well the Sapphire HD4850 Dual Slot compares to some of the other enthusiast video cards on the market. We'll be using single GPU models exclusively, to show just how much the Sapphire HD4850 Dual Slot brings to the table. All driver settings and clock speeds will be left at factory defaults for both the CPU and GPU in an effort to minimize or eliminate any variables that could impact the results. The test system used in this review is listed below. After testing the card at stock speeds, I'll overclock it to see what kind of performance can be gained. All testing is performed with the default settings in the respective control panels, as well as default settings in the BIOS of the motherboard used in this test. For this round of testing, our drivers have been updated to the 177.79 for the Nvidia cards and the Catalyst 8.8 for the ATI video cards used in this review.

With the large overclock the custom cooled MSI HD4850 gave up with the lower temperatures the cooler delivered I figured I may as well give that kind of overclock a shot on this Sapphire custom cooled card.. Bumping the GPU core up 10MHz at a time until I started having lockups got me to 674 MHz on the core and 1062MHz on the memory. I was kind of dissapointed with the results, considering I was running much cooler than the ATI reference design allows. You have that and the non-reference design of this card. But when you come down to it this really is close to the levels that the reference design Sapphire HD4850 reached. The big plus is that this card does it over 20 degrees Celsius cooler. No two components are the same, so overclocking is not really a one size fits all proposition. Just because one video card may reach a higher performance level than another can be attributable to one or more components. So, with that said, your mileage may vary. 49MHz worth of overclock on the GPU core and 69MHz on the GDDR3 Qimonda memory equates to a free performance increase, for the price of your time to go after it.
