Testing:

Testing of the Sapphire HD6850 1GB Vapor-X Edition will consist of running it and comparison cards through the OverclockersClub.com suite of games and synthetic benchmarks. This will test the performance against many popular competitors. Comparisons will be made to cards of equal and greater capabilities to show where they fall on the performance ladder. The games used are some of today's newest and most popular titles to give you an idea of how the cards perform relative to each other.

The system specifications will remain the same throughout the testing. No adjustment will be made to the respective control panels during the testing, with the exception of the 3DMark Vantage testing, where PhysX will be disabled in the NVIDIA control panel if applicable. I will test the cards at stock speeds, then overclocked in order to see the effects of any increases in clock speed. The cards are placed in order from highest to lowest performing in the graphs to show where the cards fall by comparison. The drivers used are the 11.7 Catalyst drivers for AMD-based cards and the 275.27 for NVIDIA-based cards.

Overclocking:

  • Sapphire HD6850 1GB Vapor-X Edition | GPU - 1030 MHz | Memory - 1249MHz

Well, I was already aware of what most HD6850s were capable of through overclocking, and I found that I hit a similar wall with this one. The core speed, while using a voltage of 1.225V, got stuck at 1030MHz. Everything after that began to artifact and show poor, unstable image quality. At 1030MHz, this card produced the highest core clock speed of all of the comparison cards! This is a slight improvement over the XFX HD6850 comparison card, which maxed out at 1020MHz. The memory, on the other hand, pulled ahead at 1249MHz where the comparison HD6850 stopped at about 1200MHz. With a cooler that is slightly improved over the reference, XFX version, this isn't to be unexpected. The results here are good, especially with the near 30% overclock on the core. The memory didn't do AS well, but still fared an approximate 15% overclock and rightfully obtained a 3rd place trophy. Hopefully, we'll see some similar scaling in our testing!

 

 

 

 

Maximum Clock Speeds:

Testing for the maximum clock speed consists of looping Crysis Warhead and Unigine 2.5 for 30 minutes each to see where the clock speeds will fail when pushed. If the clock speed adjustment fails, then the clock speeds and tests are rerun until they pass the full hour of testing.
