GTX 275 versus HD 4890
Continuation: Review: Ati Radeon HD 4890 versus Nvidia Geforce GTX 275


For this review we used brand new drivers delivered by AMD and Nvidia. The Catalyst we were given has the internal serial number 8.592 - The Catalyst 9.3 WHQL is tagged with 8.591. For the Nvidia cards we got the Geforce 185.63.

The test system was based on the following components:

• CPU: Intel Core i7-920 @ 3.500 MHz (175x20)
• Motherboard: Asus P6T (X58 chipset)
• RAM: 3 x 2.048 MiByte DDR3-1400 (7-7-7-20)
• PSU: Enermax Modu 82+ (625 Watt Nennleistung)
• Display: Dell Ultrasharp 3008WFP (30 inch LCD, 2.560x1.600 Pixel)

Geforce graphics cards (clock speeds: GPU/Shader/VRAM)
• Geforce GTX 285 (648/1.476/1.242 MHz, 1.024 MiByte)
• Geforce GTX 275 (633/1.404/1.134 MHz, 896 MiByte)
• Geforce GTX 260-216 (576/1.242/999 MHz, 896 MiByte)
• Geforce 8800 GTX (576/1.350/900 MHz, 768 MiByte)
• Geforce 8800 GT (602/1.512/900 MHz, 512 MiByte)

Radeon graphics cards (clock speeds: GPU/VRAM)
• Radeon HD 4890/1G @ 950/2.200 MHz, 1.024 MiByte ("Average OC")
• Radeon HD 4890/1G (850/1.950 MHz, 1.024 MiByte)
• Radeon HD 4870/1G @ HD 4890 (850/1.950 MHz) (for RV790 vs. RV770 at the same frequencies)
• Radeon HD 4870/1G (750/1.800 MHz, 1.024 MiByte)
• Radeon HD 4870/512M (750/1.800 MHz, 512 MiByte)
• Radeon HD 4850/512M (625/993 MHz, 512 MiByte)

Drivers
• Geforce 185.63 Beta (default settings with VSync off)
• Catalyst v8.592; 9.3 based (default settings with VSync off)

All FSAA setting have been applied in-game and anisotropic filtering is either activated in the game or forced via the driver.

Benchmark selection
GTA 4: New benchmark
 
GTA 4: New benchmark [Source: view picture gallery]
We tested the graphics cards in the following games:
• Call of Duty World at War v1.3
• Crysis Warhead v1.1
• Fallout 3 v1.0.4.6 + HD-Texture pack
• Far Cry 2 v1.02
• GTA 4 v1.030
• Half-Life 2: Episode 2 + Fakefactory Cinematic Mod v9.51
• Stalker: Clear Sky v1.0008
• Race Driver: Grid v1.2


The games have been tested with maximal detail settings and the following screen resolutions:

• 1.280 x 1.024, 4x MSAA/16:1 AF
• 1.680 x 1.050, 4x MSAA/16:1 AF
• 1.920 x 1.200, 8x MSAA/16:1 AF
• 2.560 x 1.600, 8x MSAA/16:1 AF

We reserved the right to leave out irrelevant seetings (like Crysis at 2,560 x 1,600) and FSAA isn't always active (in GTA 4 for example). See the individual benchmark charts for more details.
