Contemporary graphics cards surpass the older products across a number of parameters like speed, functionality, complexity and, alas, power consumption and heat generation. We would like to introduce to you a method of measuring power consumption – and heat dissipation, too – for modern graphics cards and will also share with you the results of the tests, for the card running at their nominal frequencies and after overclocking.
RADEON 9600 Pro
The RADEON 9600 Pro has a lower GPU frequency than the RADEON 9600 XT. Here’s a 9600 Pro card from PowerColor:
The memory on this card is not cooled at all – there’s only a GPU cooler:
The nominal frequencies of the card are 400/600MHz. I reached 450/740MHz at overclocking. Power consumption measurements:

The RADEON 9600 Pro has a lower power consumption that the RADEON 9600 XT, and there’s nothing wrong with it. The frequencies of the GPU and the graphics memory grew by 12.5% and 26.7% at overclocking, and the power consumption increased by 5.9% and 7.4% in the Idle and Burn modes, respectively.
