So I have a laptop with a 1060 and i was overclocking and I find my self limited to 1700-1750 MHz core clock. I am not complaining about my overclock because I am getting great performance. But it is GPU boost limiting me. I can set it to 2200 MHz and it will still limit it self to 1700-1800 with 99% core load. Now my question is how do some people with the same card get it to go to 2000+ MHz? I am stumped on how they do it. Because this card is power limited that is why mine stops at 1700-1800 because i'm pulling 75-80 Watts which is the cards power delivery limit. But on 3DMarks website people are getting 2000+ and I just can figure it out. If anyone has Ideas for why they can push it that far with out limits please let me know because I am stumped. PS here is a link to some of the results I am seeing.

As stated, if the GPU is power limited as you are saying, it comes down to the laptop manufacturer's design and safety features. I could theorize a hardware modification you could make which would defeat the power limit by bridging the current sensing shunt resistor(s) using either solder or a rear-window defog trace repair pen (if low enough resistance and painted on heavy enough), but it would void your laptop's warranty and may not be safe for your laptop's video card, laptop motherboard, laptop battery, or laptop power supply. Decreasing the core voltage (if possible and if stable) should lower your video card's power draw and may allow a bit more GPU boost (as long as you don't hit vrel limit right away instead due to to lower core voltage). There is likely a software workaround as well, but no one may have yet discovered or distributed it.

Keep in mind your laptop's price and marketing. It may score lower due to design constraints, compromises, and pricing. It looks like you are comparing a Dell to a MSI gaming laptop.
