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 Palit HD4850 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 Palit HD4850 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.

While trying to overclock the HD4670 I was pretty much stifled at each turn. Even moving up 20MHz would cause a driver crash and require a reboot. Trying to scale the memory upwards was almost as bad. The initial driver was the source of some of the issue. Upgrading to the 8.10 Catalyst suite allowed the card to post a 10MHz gain on the core and and 35MHz on the GDDR3 memory. Temperature was not an issue at all during the overclocking of the card. Those in fact, stayed a respectable 59 degrees Celsius maximum. Since this card gets all of its power through the PCIe slot, it's not a barn burner by any means. On a percentage basis, this represent gains on the core of less than 2% and 3.5% on the memory. Numbers that would truly not show an increase under the benchmarking suite, so this card was not run overclocked.
