Low GPU clock on integrated 3700U

[Corbula]

I'm using a 3700u APU (it has a vega rx 10) on a HP CW1 laptop, I'm trying to run Civilization Vi and getting around 28fps on lower settings.

The 3700u gpu is meant to be clocked at 1400mhz according to the amd site but according to monitoring software ( hwinfo and afterburner) I can't get it above 700-800mhz.

I've taken a screenshot and a video of the benchmark in Civilization VI that shows the CPU clocks and GPU.

I've got drivers up to date as far as I'm aware. 

Any ideas what I can do to get it to run at 1400mhz like its designed for and hopefully some more fps? Thanks.

No there's no gtx, it's an APU so internal graphics.
