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.
With the Sapphire 5500 XT 4GB averaging 1804MHz under load in our testing, this is 24MHz slower than the ASRock 5500 XT we have also reviewed for launch. While far from a big gap, this does explain why – where memory limitations are not a factor – we saw the Sapphire card performing ever so slightly slower in our games.
Still, this clock speed is well above the rated game clock of 1717MHz, so we have little cause for complaint.
