GeForce GTX 570. Is memory overclocking necessary?

The influence of memory clock rates to performance of graphics card with GPU overclocking

Aliens vs Predator D3D11 Benchmark

Aliens vs. Predator — first person Shooter, that is laid in distant future where people stand against aliens. The benchmark can evaluate the level of performance of graphics cards supporting DirectX 11 API and includes latest possibilities of 3D graphics of modern games: tessellation, advanced shadows and SSAO (screen space ambient occlusion) technology.

  • Version: 1.03
  • API: DirectX 11
  • Graphics settings, as follows:

    • Texture Quality: Very High
    • Shadow Quality: High
    • Anisotropic Filtering: 16
    • Screen Space Ambient Occlusion: On
    • Vertical Sync: Off
    • DX11 Tessellation: On
    • DX11 Advanced shadow sampling: On

Another test, clearly demonstrating how memory clock can limit performance of an overclocked GPU.

Colin McRae: Dirt 2

The second part of well-known race simulator Colin McRae: DiRT, where the best of auto simulators is coupled with awesomeness of modern technologies. We used built-in benchmark tool for graphic card tests.

  • Version: 1.1
  • API: DirectX 11
  • Graphics settings: Ultra

Dirt2

And again we see that GeForce GTX 570 @950/1050 beaten by the same card with lower GPU clock but higher memory clock. GTX 570 @950/1250 confirmed the fact that memory was the bottleneck in that case.

Metro 2033

Aerial first person shooter based on Dmitriy Gluhovskoj’s bestseller. Metro 2033 is a game with actions taking place in destroyed underground of post-apocalyptic Moscow.

The game widely uses capabilities of DirectX 11 API, including physics, by mean of graphic cards. We used an integrated benchmark tool that becomes available after game update.

  • API: DirectX 11
  • Graphics settings: Very High
  • Texture Filtering: 16x
  • Tessellation: On
  • DOF: On
  • Advanced PhysX: Off
  • Demo record: Frontline

Metro 2033 turned to be the application in which GPU overclock can be restricted by memory clock too.

S.T.A.L.K.E.R.: Call of Pripyat Benchmark, SunShafts

The last part of popular game series now supports DirectX 11. Official benchmark was used for tests. SunShafts test was chosen as the most resource-intensive.

  • API: DirectX 11
  • Graphics settings:

    • Preset: Ultra
    • Renderer: Enhanced Full Dynamic Lighting (DX11)
    • SSAO Mode: HBAO
    • SSAO Quality: High
    • DX 10.1: On
    • Tessellation: On
    • Contact Hardening Shadows: On
    • In Anti Aliasing mode: MSAA for A-tested objects: DX10.1 Style [Higher Quality]

Call of Pripyat Benchmark

Finally, a test run of S.T.A.L.K.E.R.: Call of Pripyat Benchmark was sensible both to memory and GPU overclocking. This is a kind of game that can’t get full up, no matter how well you feed it.
