Performance in Synthetic Benchmarks
The overall score of the PowerColor card is such as you could expect it to get after viewing the results of the previous tests. It is somewhat slower than the ordinary ATI Radeon HD 2600 Pro – the reduced memory frequency proves to be a weightier factor than the doubling of its amount.
It’s all predictable in the first and third tests but the PowerColor HD 2600 Pro 512MB makes a sudden rush in the second test, outperforming the reference card by 20%! Unfortunately, RivaTuner cannot track the graphics memory usage in the Windows Vista environment, so we don’t know how much data is used in the second test. It can be over 256 megabytes due to the dynamically generated vegetation (and shadows) which determines the victory of the PowerColor card.
