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.
Looking at the card's clock speed under load, after a 30min Fire Strike Ultra stress test we saw the clock speed average 1774MHz, almost 60MHz faster than the Founders Edition. Both cards do have the same rated boost clock (1645MHz) but as we will see on the next page, the PNY XLR8 runs quite a bit cooler allowing GPU Boost to push clock speed further.
