AMD Radeon RX 560 4GB Review: 1080p Gaming On The Cheap

Temperatures, Clock Rates & Overclocking


Manual overclocking got us all the way to 1460 MHz under The Witcher 3. This represents a respectable 134 MHz boost. We also increased the memory clock rate by 200 MHz without any stability problems over an hour-long session in the same game.

At a glance, that doesn't seem like a lot of headroom. But depending on the game, it could mean anywhere from 7- to 10%-higher frame rates. The temperatures don't climb out of control, either.

Temperatures & Frequencies

First, we compare temperatures and clock rates before and after overclocking.

In Depth: Temperature vs. Clock Frequency

Our infrared temperature analysis shows that the VRM area and a spot close to the GPU package get very hot. All of these values are still in an acceptable range, though. Ultimately, the 100W consumed by this card doesn't pose much of a challenge for its thermal solution.
