Graphic Chip Comparison And Test Configuration

How Much Power Does Your Graphics Card Need?
By

This overview shows the graphics cards and the standard frequencies of their graphics processors (GPUs), shaders, and graphics memory (with AMD, shader and GPU frequencies are identical). If you use an overclocked graphics card (OC), it will differ from the values listed, and will have a somewhat higher power consumption. You should include this increased power consumption in assessing the necessary power supply wattage, and can add half the percentage of overclocking to the power consumption as “insurance.” For example, if the graphics card (GPU) is overclocked by 10%, then you should add 5% to the maximum power consumption of the graphics card. If you don’t know the clock rates of your video card, you can use the tool GPU-Z to read the values.

Memory clock speed=DDR-Clock rate doubled, physical frequency is cut in half

DDR5-clock rate quadrupled, physical frequency is one fourth

SPs=Stream-Processors; P and V=Pixel shader and Vertex shader

TC=Turbo Cache HM=Hyper Memory

OC=overclocked (clock frequency higher than standard) <br>

SLI=Parallel operation with 2 Nvidia cards

3SLI=Parallel operation with 3 Nvidia graphics chips

4SLI=Parallel operation with 4 Nvidia graphic chips

CF=CrossFire parallel operation with 2 ATI cards

3CF=CrossFire parallel operation with 3 ATI graphic chips

4CF=CrossFire parallel operation with 4 ATI graphic chips

R680=2xRV670

R700=2xRV770

Shader 2.0=DirectX 9.0; 3.0=DirectX 9.0c; 4.0=DirectX 10; Shader 4.1=DirectX 10.1

This is the standard configuration of the graphics card test system, and is the basis by which the power consumption of a complete system was determined.

The power consumption is given in watts; 1,000 watts (1 kW) is used as a baseline for the electricity used. The cost of a kilowatt hour differs depending on the region and electricity supplier. We used 20 cents (the price at the Munich utility company Stadtwerke München) for the electricity calculation. PSU stands for the power supply unit.
