That's not the case. A 5060 has a 145W TDP, which is borderline feasible. A 5090 is 575W, which is approaching furnace territory.

Thanks, fixed. I intended the 5090 indeed but haven't had a coffee.

Anyway, even the 145W of a 5060 are... an ugly challenge to meet. The 2019 16-inch MacBook Pro for example can happily guzzle 90W when you max out the i9 CPU and the dGPU and gets uncomfortably warm after a few minutes once the aluminium case goes into thermal equilibrium.

Add in even just a 60W CPU to match with a 5060 and you're looking at double that heat to be dissipated!

Weren't those MacBooks relatively thin – the same as the OG retinas of 2012-2013?

A friend of mine has an Asus with some Nvidia GPU (3070? not sure), a 5th gen ryzen 9 and a 200+W power brick.

That thing is twice as thick as my 2013 MBP and the case is plastic. It also has more vents than my mbp, each of which has more surface area than all those on the mbp combined. I also suspect the fans are bigger.

He actually bought it to play games on it and never complained about performance dropping after a while. So I suppose it manages to move the 200 W of heat somehow.

That’s still about two orders of magnitude less than an electric furnace (100A at 240V single-phase is 24kW)

Resistive heat is really crappy, a 7-8kW heat pump could replace the hypothetical 24kW furnace.
