You are thinking of bitcoin mining on gaming laptop in 2022 which is not at all possible but if you have been into this at earlier days when it was launched then you might be able to do it but now when the ASIC machines are deployed for mining bitcoin with so much computation powers you Rtx don't stand a chance against them.
There are big mining farms with heavy equipment into mining using ASIC machines like this and we are talking about laptop mining which could not help us at all :
The consequences of laptop mining you have seen above also as mining would require your laptop to run for 24x7 without any disruption which will heat it up eventually even it's RTX 2080 single card also which will then cause internal damage to your laptop and most probably within few days only.One of my friend tried it with Alien predator back two years and then it has to be repaired as it was under insurance.
You think of dedicating your laptop to mining so suppose it's $1000 and additional cost of RTX 2070 8gb but what will you gain on daily basis? Few satoshis worth $1-$2 per day so is it profitable according to you?
The Bitmain have been continuously making more improvement to ASIC machines for mining increasing the TH/s for fast hashes calculation and the last post i made about them have this machine
The mining machine will have a hashrate of 198 TH/s, power efficiency (@ 35°C) of 27.5 joules per terahash (J/TH) and will consume 5445 watts of power, according to a tweet.
In comparison, the previous top-of-the-line Antminer, S19 XP, has a hashrate of 140 TH/s, power efficiency (@ 25°C) of 21.5 J/TH and consumes about 3010 watts.
The new model will also incorporate the “latest liquid cooling technology” and is designed for use with Bitmain's Antspace HK3 mining container.
The adoption of liquid cooling has been increasing in recent years as an alternative to traditional air-cooling, which allows mining machines to be immersed in a synthetic hydrocarbon compound liquid that has no electrical conductivity and is fully biodegradable.
This specialized liquid can reduce heat, power consumption and noise stemming from the computers, as well as prolong the lifespan of the machines, allowing miners to maximize profit in an increasingly competitive market.
So it's not advisable to you to go through this way and best is to find some altcoins for the same purpose but then also the question is how much profitable it would be as you are spending some amount on it including electricity, maintanence cost of your hardware.
