Gaming laptops are notorious for dying from overheating. These things need to be meticulously maintained if you want to use them for their intended purpose for long.

You’re missing the point:

4090 with 7900x3d and 850w psu running games at max will generally use about 550w. The same build swapping in a rx 7900xtx is ever so slightly more economical at around 520w. Getting into pissing matches about brand loyalty (when they’re both companies that will ultimately fuck you over for another cent) is stupid, and doesn’t change that this box, if accurate to advertising, does 80% of the work they do at 140w under load (essentially 1/4 the power of your precious amd, which you’d still be using here btw).

It would matter more for the environment if tons of gamers actually had these GPUs but based on what valve is saying here (and the fact that as others have said they likely have very good statistics on the machines accessing steam) they likely don’t. Most fancy GPUs probably go to crypto farms and llm bullshit, which is dumb and means this doesn’t really matter I guess
