Since the various turbo technologies are becoming more and more advanced, sufficient cooling to keep clock speeds at a high level is becoming more relevant for the actual performance of the cards during gaming sessions. If a card were to start thermal throttling after a couple of minutes, the performance would naturally decrease as well. For this reason we're now also performing a throttling test, that will determine whether the performance of a card stays consistent, even after a long period of gaming.
The throttling test consists of our F1 2015 benchmark, looped seventeen times, which takes about 30 minutes. In the meantime we monitor the clock speeds and temperatures by writing them off to a log file each second. Afterwards we analyze the data, to make the graph below.
Clock speed and temperatures
After three and a half minutes the Gigabyte Aorus Xtreme reaches a temperature of 69 degrees Celsius. The clock speed then varies between 1915 and 1880 MHz, which means that the graph will look similar to the one from the Founder Edition - however the line is a bit higher.
Comparison with Founder Edition
If we put the Aorus and Founders Edition in one graph, we find that both card indeed show similar behavior. The difference between the two is that the Founders Edition stabilized at about 1733 MHz, whereas the Aorus Xtreme did this just under 1900 MHz. This is a difference of nearly 10 percent.
