Testbed and Methods

We are going to investigate the performance of Radeon HD 4890 graphics card on our universal testbed with the following configuration:

  • Intel Core i7-965 Extreme Edition processor (3.2GHz, 6.4 GT/s QPI);  
  • Asus P6T Deluxe mainboard (Intel X58 Express chipset);
  • Corsair XMS3-12800C9 (3x2GB, 1333MHz, 9-9-9-24, 2T);
  • Maxtor MaXLine III 7B250S0 HDD (250GB, Serial ATA-150, 16MB buffer);
  • Enermax Galaxy DXX EGX1000EWL 1000W power supply;
  • Dell 3007WFP monitor (30", 2560x1600@60Hz max display resolution);
  • Microsoft Windows Vista Ultimate SP1 64-bit;
  • ATI Catalyst 9.3 for ATI Radeon HD;
  • Nvidia GeForce 182.08 WHQL for Nvidia GeForce.

The graphics card drivers were configured in the same way as before: to provide the highest possible quality of texture filtering and to minimize the effect of default software optimizations. As a result, our ATI and Nvidia driver settings looked as follows:

ATI Catalyst:

  • Smoothvision HD: Anti-Aliasing: Use application settings/Box Filter
  • Catalyst A.I.: Standard
  • Mipmap Detail Level: High Quality
  • Wait for vertical refresh: Always Off
  • Enable Adaptive Anti-Aliasing: On/Quality
  • Other settings: default

Nvidia GeForce:

  • Texture filtering – Quality: High quality
  • Texture filtering – Trilinear optimization: Off
  • Texture filtering – Anisotropic sample optimization: Off
  • Vertical sync: Force off
  • Antialiasing - Gamma correction: On
  • Antialiasing - Transparency: Multisampling
  • Multi-display mixed-GPU acceleration: Multiple display performance mode
  • Set PhysX GPU acceleration: Enabled
  • Other settings: default

The list of benchmarks includes the following gaming titles and synthetic tests:

First-Person 3D Shooters

  • Call of Duty: World at War
  • Crysis Warhead
  • Enemy Territory: Quake Wars
  • Far Cry 2
  • F.E.A.R 2: Project Origin
  • Left 4 Dead
  • S.T.A.L.K.E.R.: Clear Sky

Third-Person 3D Shooters

  • Devil May Cry 4
  • Prince of Persia


  • Fallout 3
  • Mass Effect


  • Race Driver: GRID
  • Tom Clancy’s H.A.W.X.


  • Red Alert 3: Uprising
  • World in Conflict

Semi-synthetic Benchmarks

  • Futuremark 3DMark06
  • Futuremark 3DMark Vantage

We selected the highest possible level of detail in each game using standard tools provided by the game itself from the gaming menu. The games configuration files weren’t modified in any way, because the ordinary user doesn’t have to know how to do it. We made a few exceptions for selected games if that was necessary. We are going to specifically dwell on each exception like that later on in our article.

Besides PowerColor HD4890 Plus we have also included the following graphics accelerators to participate in our test session:

  • ATI Radeon HD 4850 X2 (2xRV770, 625/625/2000MHz, 1600sp, 80tmu, 32rbe, 2x256-bit, 2x1024MB GDDR3)
  • ATI Radeon HD 4870 1GB (RV770, 750/750/3600MHz, 800sp, 40tmu, 16rbe, 256-bit, 1024MB GDDR5)
  • Nvidia GeForce GTX 285 (G200b, 648/1476/2484MHz, 240sp, 80tmu, 32rbe, 512-bit, 1024MB GDDR3)
  • Nvidia GeForce GTX 260 Core 216 (G200b, 576/1242/2000MHz, 216sp, 72tmu, 28rbe, 448-bit, 896MB GDDR3)

Since it is the first Radeon HD 4890 that we have received so far, PowerColor graphics card was tested as a regular non-overclocked model (without the “OC” in the name) at 850/975 (3900) MHz frequencies and at maximum overclocked speeds of 1000/1200 (4800) MHz.

We ran our tests in the following resolutions: 1280x1024, 1680x1050, 1920x1200 and 2560x1600. Everywhere, where it was possible we added MSAA 4x antialiasing to the standard anisotropic filtering 16x. We enabled antialiasing from the game’s menu. If this was not possible, we forced them using the appropriate driver settings of ATI Catalyst and Nvidia GeForce drivers.

Performance was measured with the games’ own tools and the original demos were recorded if possible. We measured not only the average speed, but also the minimum speed of the cards where possible. Otherwise, the performance was measured manually with Fraps utility version 2.9.8. In the latter case we ran the test three times and took the average of the three for the performance charts.
