How can I monitor frequency of integrated GPU (Intel HD 620)?

Various benchmark programs say that my GPU is performing very, very poorly for what it is (which is a fairly-weak-to-begin-with integrated Intel HD 620 graphics). So I'm wondering if it is kicking its frequency up when under load as it's supposed to, or is somehow throttled to stay at base frequency. What utility can I use to watch the GPU frequency while I am putting it under load? HWinfo just has a blank square where it is supposed to show GPU frequency, and HWmonitor doesn't display GPU frequency at all.

Okay, Duck Duck Go didn't know the answer, but Google did ... and the answer, for anyone interested, is GPU-Z from Techpowerup. Confirmed that my GPU is indeed ramping up frequency when under load. Though, interestingly, not to its full advertised max frequency, even when undergoing a graphics benchmark test.

You're using a laptop. Most low end or entry level laptops have mediocre graphics due to the APU.

Yeah, I get that; I'm not expecting high-end or even middle-end performance. But HD 620 graphics are only used in mobile processors, so if my system's benchmarks are being compared against other HD 620 systems, well, they all are going to be laptops. And yet NovaBench and UserBencharks says that my GPU performance is terrible compared to comparable HD 620 systems. It's actually working fine for my uses, but I'm just curious about that benchmark comparison so am trying to understand it. I suppose when I have time I will try running some graphics-focused benchmarks programs.
