Thank you for contacting the Intel community.
Well, you can try going down to the bottom right corner of the screen and looking for an icon that shows a battery and click on it. Chances are it is set to Power Saver. If that is on, it will turn your clock speed down. So when you are on it, look for one called "High Performance mode". If it is not there click on, "More Power Plans". And click on an arrow that will allow you to click on that power plan. Therefore that will boost your clock speed.
Also, make sure your BIOS is running at default settings and that is up to date and as well as all of your drivers from your computer manufacturer website. Check in your BIOS that all cores are enabled.
If that does not work, try removing you video card and use only the graphics from the processor, if you need the graphics driver for the processor you can download it here:
Try that troubleshooting if you could and do your tests to see how it goes.
I hope that can help.
Thank you for the information, being that the case, you can download the Intel® Extreme Tuning Utility (Intel® XTU), run a stress test with it and check the CPU usage.
I will appreciate if you can attach a picture of the result.
Also, you can install the latest graphics driver, you can download it here:

Make sure the maximum processor state for the active power scheme says 100%.
Please let me know.
Being that the case, try the Intel® Processor Diagnostic Tool, the purpose of the Intel® Processor Diagnostic Tool is to verify the functionality of an Intel® Microprocessor. The diagnostic checks for brand identification, verifies the processor operating frequency, tests specific processor features, and performs a stress test on the processor.
