Here we present the average clock speed for each graphics card while running the 3DMark Fire Strike Ultra stress test for 30 minutes. We use GPU-Z to record the GPU core frequency during the Fire Strike Ultra runs. We calculate the average core frequency during the 30 minute run to present here.
While the margins are certainly not at all big, we did see the EVGA SC Ultra coming in marginally slower than our other two 1660 SUPERs throughout our game testing. This is explained when looking at the card's clock speed under load, with an average core speed of 1895MHz. This is 33MHz slower than the Palit GamingPro OC and 52MHz slower than the Gigabyte Gaming OC. Do bear in mind, however, that the card is still exceeding its rated boost clock (1830MHz) by about 65MHz.
