Testbed and Methods

We tested the ASUS Extreme N7800GT/2DHTV graphics card on the following testbed:

• AMD Athlon 64 4000+ CPU (2.40GHz, 1MB L2 cache)
• ASUS A8N-SLI Deluxe mainboard (NVIDIA nForce4 SLI chipset)
• OCZ PC3200 Platinum EL DDR SDRAM (2 x 1GB, CL2-3-2-5)
• Samsung SpinPoint SP1213C (Serial ATA-150, 8MB buffer)
• Creative SoundBlaster Audigy 2 sound card
• Cooler Master Real Power 450 power supply (RS-450-ACLY, 450W)
• Dell P1130 and Dell P1110 monitors (21”, 1800x1440@75Hz max display mode)
• Microsoft Windows XP Pro SP2 with DirectX 9.0c
• ATI CATALYST 5.9 (8.173.1-050921a-026915E) for all games and ATI CATALYST 5.10a for Doom III and Quake 4;
• NVIDIA ForceWare 81.85

We set up the ATI and NVIDIA drivers in the following way:

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 81 .85 :

• Image Settings: Quality
• Vertical sync: Off
• Trilinear optimization: On
• Anisotropic mip filter optimization: Off
• Anisotropic sample optimization: On
• Gamma correct antialiasing: On (for GeForce 7 only)
• Transparency antialiasing: Off (for GeForce 7 only)
• Other settings: default

We select the highest graphics quality settings in each game, identical for graphics cards from ATI and NVIDIA. If possible, we use the games’ integrated benchmarking tools (to record and reproduce a demo and measure the reproduction speed in frames per second). Otherwise we measure the frame rate with the FRAPS utility. If it is possible, we measure minimal as well as average fps rates to give you a fuller picture.

We turn on 4x full-screen antialiasing and 16x anisotropic filtering in the “eye candy” test mode from the game’s own menu if possible. Otherwise we force the necessary mode from the driver. We don’t test the “eye candy” mode if a game engine doesn’t support FSAA.

ASUS was kind to offer us two samples of the Extreme N7800GT/2DHTV, so we had an opportunity to test them in the SLI mode. Besides the ASUS Extreme N7800GT/2DHTV, the following graphics cards took part in this test session:

• GeForce 7800 GTX (G70, 430/1200MHz, 24p, 8v, 256-bit, 256MB)
  for details see our article called NVIDIA GeForce 7800 GTX: Monstrous Gaming Performance Unleashed
• RADEON X1800 XT (R520, 625/1500MHz, 16pp, 8vp, 256-bit, 512MB)
  for details see our article called ATI RADEON X1800 XT and XL Performance: Crushing NVIDIA's 7800?
• RADEON X1800 XL (R520, 500/1000MHz, 16pp, 8vp, 256-bit, 256MB)
