1080 Mobile vs 1070 desktop

[RMFLB]

Not that it matters too much, but I recently bought a 144hz monitor. I have an Asus Gl702Vi laptop with a 7700hq and gtx1080 in it. Even on the lowest settings of BO4 I can only sometimes hit towards that mark with the majority being in the low 100's to 120fps. My buddy that I play with everyday has a 7700 and gtx 1070 in an actual desktop and consistently hits over 180. When I was researching the mobile version of the gtx 1080, pretty much all sources said that it would still compete with the desktop gtx 1070 version. I am asking some of you guys that may have a bit more knowledge than me, is this the case, or am I missing something somewhere with settings possibly? Pubg on low settings I hit 60-90fps. Overwatch on medium I hit about 160fps.

Your GTX 1080 is better than a 1070, but your mobile CPU is probably what's holding you back.

I would say that if that’s the trend with other games too, then you can assume his system is superior in some way. Either specwise or due to the thermal limitations you face using a laptop.

You are probably cpu bottlenecked in terms of clocks.
