Testing:

Testing of the Sapphire HD6870 Vapor-X 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 it falls 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 all of the testing (which is listed below for your convenience). There will be no adjustments 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. I will begin all of the testing at stock clock speeds, then go through and overclock the video card and re-run the testing to see how much additional performance is available. We did recently change the way that our graphs are going to be displayed and setup, again for your convenience. I will show you the highest scoring cards all the way to the left hand side of the graph with the lower performing cards on the right hand side. Due to the fact that there is a large amount of cards being displayed in each graph, to make it easier for you to determine which card is which, I will keep the same color code for each graphics card throughout the article.

Overclocking:

  • Sapphire HD6870 Vapor-X 1000/1200MHz

When it came down to overclocking the Saphire HD6870 Vapor-X video card, things were pretty straight forward, I used MSI Afterburner to overclock the card as high as I possibly could by increasing the Core Clock by 10MHz at a time until I reached 1000MHz which is the limitation of Afterburner. Once I hit the wall of the application, I began to wonder if the card would be able to go any higher and decided to try out the Sapphire TRIXX software which after I downloaded and installed it, found out that the maximum allowed Core Clock in the software was 1500MHz. However, I could not seem to get the card to stay stable enough for benchmarks past 1000MHz. I was disapointed in the fact that I could not adjust the GPU voltage with either the MSI or Sapphire software. However, if I would have been able to, I'm sure that I could have seen much higher core clock speeds. Once the core clock was nailed, it was time to overclock the memory. I used the same technique for the memory overclocking as I did with the core clock. Raise by 10MHz then test and if it passed stability testing I would raise until it wouldn't. The maximum that I could get out of the memory was 1200MHz. So I was able to get a maximum of 11% increase on the core clock and 14% on the memory clocks, not too shaby when you are able to hit 1 GHz on your GPU core!

 

Maximum Clock Speeds:

In the past, I had used MSI's Kombuster utility to check for stability coupled with the ability to run through the entire test suite. I have found that some game tests would still fail with this utility, so I have moved to testing with several games at maximum settings through several resolutions to verify the clock speeds that are listed below. Why the change? I have found some cards will play fine at a 4xAA setting, but fail when using 8xAA due to the increased graphics load. If it fails, then the clock speeds and tests are rerun until they pass.
