Definitely better than desktop GPU for ETH.
Ergo it gives about 162MH/S.
Have to test on other algos yet.
How much is the cost of your laptop OP? In my country a laptop with rtx3070 onboard costs over 2000$ where as it's same with a desktop RYX3070 too but buying two laptops with gtx1660 ti reduced the money alot cos I can get that for around 750$ each
Cost is same in my country as well $2k.
Efficiency wise RTX 3070 laptop would be better.
