Sapphire HD 4670 Review

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 HD4670 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 HD4670 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 8.11 for the ATI video cards used in this review.

Overclocked settings:

  • Sapphire HD4670 775/1065 MHz

This version of the HD4670 was much more overclocking friendly that the Powercolor version I tested. Whereas that card did not want to give up any additional clock speed, the Sapphire version easily eclipsed the marks set by that card. The memory on this card just kept scaling upwards and finally gave up the ghost at 1070MHz. I backed down the clock speed 5MHz and I was ready to go. The Core speed increase was not all that substantial, but it is easily 15MHz faster than the Powercolor card. With this additional clock speed, there should be an increase in the performance delivered without a big noise penalty as the fan spools up.
