Opening up GPU-Z, the XFX RX 5700XT shows a default GPU clock of 1670MHz with a boost clock of 1925MHz and a memory clock of 1750MHz which is 14 GHz effective.
While monitoring with GPU-Z, running a Timespy benchmark with its stock settings we see the THICC II have a max boost over 1900MHZ with it averaging around 1860MHz which is fairly close to the 1925MHz boost clock. Opening up MSI Afterburner and running the heaven benchmark it boosted a little better hitting around 1935MHz.
After spending some time with the THICC II overclocking, we were able to push the core to 2100MHz and the memory to 1900MHz which is 15.2 Gbps effective. Running our Heaven benchmark we see the XFX RX 5700XT THICC II settling in at about 2040-2060MHz core clock.
With everything maxed out, we see an impressive 6.9% increase in performance with us scoring 9659 in Timespy, which is over 600 points from our stock run.
To measure how much power the XFX RX 5700XT THICC II pulls under load, we used a combination of GPU-Z and Kill-A-Watt. GPU-Z reporting the number of watts used by the THICC II where Kill-A-Watt will report power usage from the wall. Our system idle usage settled in at 52W, during the run we saw a peak power draw of 374W giving us a difference of 322W. Surprisingly this is slightly less than the RX 5700 we reviewed previously which peaked at just over 400W. Looking at our GPU-Z logs. we hit GPU power draw of 222.0W which seems a little seeing the difference we were getting from Kill-A-Watt. Again, this was a similar situation as we seen on the RX 5700, so it possible that GPU-Z isn’t reporting the wattage correctly.
Running all our benchmarks, the XFX RX 5700XT THICC II was extremely quiet with the default fan profile with it peaking at 58C with 70C hotspots. While overclocking thevTHICC II we set the fans to 100% but after running the Timespy benchmark the fans spun down to about 55%. I’m guessing this may be a driver/BIOS issue that may be fixed in a future version. Even with the fans at 55% the THICC II still managed to stay quite cool only hitting a maximum temperature of 66C with a hotspot of 85C.
