My R9 M375 in my lenovo y700 laptop seems to have a problem, while in game and under load, the GPU keeps going from 820mhz to 1005mhz, this manifests as stutter in games and annoys me quite a lot.
Here is a picture of gpu-z while playing a game.
And also why does the gpu usage vary that much under the same load
It is supposed to stay at a 1005 mhz at all tims under a game.

Thanks for using the Lenovo forums.
Seems like the GPU gets too hot to maintain work properly, but honestly it`s not a very strong GPU anyway, so I would suggest you try to invest in a cooling pad or see if running the games at a lower settings can make any difference for you.
Hope this helps, let us know how you get on.

I have tried it and I have found out that the GPU power throttles which means that it hits the 75watt limit and steps down the gpu speed to compensate for it. If only I could increase the power limit to 90watts...

This sounds similar to the issue that I am having. My drop is much lower than yours, but do you think it could be possible that there was a Driver Issues that could be causing this? I have tried re-installing the current drivers, but have not tried to roll back drivers. With mine, it was working fine for a while, then just started get FPS Drops all of the sudden.

It could be that, although I have tried rolling back to older AMD drivers, with no luck.
Other things I have seen is that instead of running at pci ekspress 3.0 it runs at pci-e 2.0 even though the gpu is capable of pci-e 3.0 which is strange.
One more thing is that why won't Lenovo let us use official intel drivers for the intergrated graphics?

Intel does outline the OEM customization of the driver, though I cannot say if Lenovo adds or removes features to the core driver.
From Intel, there are instructions to bypass this: https://www-ssl.intel.com/content/www/us/en/support/graphics-drivers/000005469.html
But I do it the old-fashioned way: Extract the EXE, then manually update the driver, and install it from the /Graphics folder.
