Testbed Configuration and Testing Methodology

All participating graphics cards were tested in the new 3DMark 2013 in a system with the following configuration:

So, we have six graphics accelerators on AMD GPUs and six on Nvidia GPUs. The “red” camp is represented by products from three manufacturers: HIS, Sapphire and AMD. Here they are:

  

  

  

  

The honor of the “green” camp will be defended by six graphics cards from another three makers: Nvidia, Asus and Gigabyte:

  

  

  

  

As you may have already noticed, ten graphics cards out of twelve have increased default frequencies. However, we decided not to lower them to the nominal reference values, because the performance difference will be insignificant, and besides, most of the currently selling graphics cards are exactly the ones with slightly increased speeds anyway. So, we will test all the products “as is”.

In order to lower the dependence of the graphics cards performance on the overall platform speed, I overclocked our 32 nm six-core CPU with the multiplier set at 37x, BCLK frequency set at 125 MHz and “Load-Line Calibration” enabled to 4.625 GHz. The processor Vcore was increased to 1.49 V in the mainboard BIOS:

Hyper-Threading technology was enabled. 16 GB of system DDR3 memory worked at 2 GHz frequency with 9-11-10-28 timings and 1.65V voltage.

The test session started on February 7, 2013. All tests were performed in Microsoft Windows 7 Ultimate x64 SP1 with all critical updates as of that date and the following drivers:

All tests were run with standard settings. We did not adjust the benchmark launch settings in any way. Let’s check out the obtained results.
