Testbed and Methods

We measured the performance of the Gigabyte GV-NX76T256D-RH on a testbed that was configured like follows:

  • AMD Athlon 64 FX-60 CPU (2 x 2.60GHz, 2 x 1MB L2 cache)
  • ASUS A8N32-SLI Deluxe mainboard (nForce4 SLI X16) for Nvidia GeForce cards
  • ASUS A8R32-MVP Deluxe mainboard (ATI CrossFire Xpress 3200) for ATI Radeon cards
  • OCZ PC-3200 Platinum EL DDR SDRAM (2x1GB, CL2-3-2-5)
  • Maxtor MaXLine III 7B250S0 hard disk drive (Serial ATA-150, 16MB buffer)
  • Creative SoundBlaster Audigy 2 sound card
  • Enermax Liberty 620W power supply (ELT620AWT)
  • Samsung SyncMaster 244T monitor (24”, 1920х1200@75Hz max display mode)
  • Microsoft Windows XP Pro SP2, DirectX 9.0c
  • ATI Catalyst 6.6
  • Nvidia ForceWare 91.31

ATI’s and Nvidia’s drivers were set up in our standard manner:

ATI Catalyst:

  • Catalyst A.I.: Standard
  • Mipmap Detail Level: Quality
  • Wait for vertical refresh: Always off
  • Adaptive antialiasing: Off
  • Temporal antialiasing: Off
  • Quality AF: Off
  • Other settings: default

Nvidia ForceWare:

  • Image Settings: Quality
  • Vertical sync: Off
  • Trilinear optimization: On
  • Anisotropic mip filter optimization: Off
  • Anisotropic sample optimization: On
  • Gamma correct antialiasing: On
  • Transparency antialiasing: Off
  • Other settings: default

We select the highest graphics quality settings in each game, identical for graphics cards from ATI and Nvidia. We do not modify the games’ configuration files and do not use the drivers’ profiles optimized for specific games. The frame rate is measured with the game’s own tools or, if not available, with the Fraps utility. We also measure minimum frame rate where possible.

Since we gave up testing in the 1024x768 resolution, and in higher resolutions with enabled FSAA the performance of mainstream graphics cards is often below the acceptable level, we decided to stick to testing in two work modes: with maximum level of anisotropic filtering and with full-screen anti-aliasing (FSAA 4x) enabled at the same time. Besides the standard 1280x1024 and 1600x1200 resolutions we have also added the tests in 1920x1200 widescreen resolution for those games that support it.

We turned on FSAA and anisotropic filtering from the game menu. If such options were unavailable, we forced FSAA and AF through the appropriate options of the ATI Catalyst and Nvidia ForceWare driver.

Besides the Gigabyte GV-NX76T256D-RH, the following graphics cards took part in the tests:
