Lower than average performance.

Disclaimer : Laptop model is Lenovo Ideapad 320-14IKB, specs are i5-8250U with 4gb ddr4 & MX110. The benchmark was ran with the laptop plugged in.

 

I reformat my laptop and was interested on how to improve my laptop's performance using this YouTube video. Before following the guide from the video, i benchmark the laptop twice to get a baseline score using Cinebench R20. The score that my laptop get is 812 and 795. The score i got is quite low compared to other scores that i looked online on this website and this YouTube video which got 1509 and 1653 respectively.

 

Seeing that my score is considerably low compared to online results, i did some digging to find the issue. I fired up Intel's Extreme Tuning Utility and using the stress test I found that my cpu boost clock of 3.40GHz would drop down to the base clock of 1.60GHz  after 5~10 seconds of stress testing. Even after I increase the power limit of the cpu in XTU the clock speed will drop to 1.60GHz. I do know that the boost clock of 3.40GHz is only for 1 core and not 4 which what the stress test is using.

 

The cpu is also not thermal throttling because it does not hit the thermal limit and will max out ~72c. The only warning that intel XTU gives is the "Power Limit Throttling" but increase the power and the offset voltage of the cpu does not fix the issue.

 

Right now i'm lost and have no idea on how to solve and what cause this issue.
