In a laptop the bottleneck will not be a single stick of 16GB/8GB RAM (unless your exceeding RAM usage which is not what the topic is about) it will likely be the weak low clocked CPU that can't boost to it's supposed high boost state for more than a second at a time before throttling back down again due to power, the cooling solution... usually inadequate and contribute to the previous point and then there's the GPU, it will either be too weak being a mobile variant or again the cooling isn't adequate to enable it to hit and sustain peak performance. Of course that's assuming there's an SSD in said laptop as most 2.5" HDD's unless you go for higher end are pretty poor so HDD is more of an afterthought IMO though I would be looking at the things I mntioned before worrying about running dual or single channel RAM imo anyway, not fact.
If ya buying ya laptop at BestBuy on sale for $5990, this will likely be the case. But like the desktop, building what you need is going to best serve your needs. You could opt for a mail order gaming laptop and pay a price premium ... or you can just have the laptop custom build you your specifications for less money.
Pick your screen, pick your CPU, pick your GPU, pick your RAM ... pick desktop components if ya like:

With the mobile PUs / GPus, most Clevo distributors preconfigure CPU / GPU / Sceen "base builds" (i7-9750H / i7-8750H .... 1660 thru 2080 ) and you add the options from there. But what is important today is that CPU and GPU performance differs little from their non mobile counterparts.

Yes, agree that the typical buyer who picks out a PC in Best Buy doesn't know this kinda stuff. But I'd be surpised if 1 in 20 of TPUs reguars do not. One thing i do not understand why most techies will build their own custom desktop, why that don't entertain buying custom made laptops when one is needed. For me a lappie is a necessity for jobsite and on the road work ... most don't have this requirement. But after working hours, (live in a 200 year old dairy barn w/ office in the hayloft) I will often sit at my desk and fire up a game for a while ... but after dinner or after I get buttsore from sitting in the office chair all day, going downstairs and streaming a movie or continuing the game in a Lazy-Boy is a better option ... and I lose very little on the change.
It's not like it costs more to do so. The Clevo distributors are not permitted to **advertise** pricing below a set bottom price, they will negotiate with you ... and those discounts can be substantial.
And yes, I can overclock and run Furmark / RoG Real Bench w/o issue.
