GPU clock speed "spike"



I have a Ryzen 3 2200G APU with no discrete graphics card.  I am not overclocking either the CPU or the GPU.  I notice that occasionally the GPU clock speed will "spike" occasionally up to 1600 MHz, when it normally runs at 1100 MHz.  The spike appears to happen for a fraction of a second.  I have not been able to replicate the problem, but it appears to happen more when I wake up the monitor.  The computer is not in sleep mode, it is running but locked.

My computer seems to run just fine, so I am not sure if this is just a false reading or if it truly is happening.  Can you provide any insight?

PS - Sorry, this is my first post, and the debug file is not attaching, will try in next post.
