Sapphire RX VEGA 64 Limited Edition Review

Fan noise, Temperatures and Overclocking

For all benchmarking, the i7 7700k was overclocked to 5.0 GHz. The overclocked was validated using CPU-Z. The GPU was overclocked using ASUS GPU Tweak II. Compared to the RX 400 and RX 500 series, the RX Vega card overclocked very well. With the 400 and 500 series, I struggled to at 40 MHz to the core with certain cards. However, with the RX Vega 64 LE, I added 210 MHz to the core, hitting 1840 MHz. The memory was a different story. For some reason, I GPU Tweak II would only allow for a +18 on the memory, getting the memory clock to 1908 MHz. I tried AMDs WattMan, and it would just crash. GPU Tweak II was the only tuning utility that would work with this card. The card hit its max temp in FurMark at 87°c. While gaming, the card stayed in the upper-60s. The card idles around 57°c. This being a blower style card, higher temps and a louder fans was expected. I left the fans on auto mode. Even at the cards max temperature of 87°c, the fans never went above 58% and ran at about 40 decibels. When I put the fan to 100%, it hovered around 46 decibels. Not too bad.
