Any Intel/AMD mobile processor is going to get hot doing simple things - new or old. It has always been this way.
M1/M2 is the way to go if you want cool operation on virtually all workloads.
Oh baloney. Doing the same thing on my Ryzen 5650U won't crack 50 C, it regularly idles around 30-40 C whereas the MBP I don't think I ever saw below 45. And my prior Skylake system was way cooler too. Usually was around 70 C gaming. The 2018 15" MBP chassis is particularly terrible for the chips they put in there. The i9 infamously would perform worse than the i7 in benchmarks for long duration tasks.
What do you mean? There was no M1 system in 2018. Only the Intel machine with cooling problems.
My MBP M1 Pro is usually compiling big chunks of software. (Granted, not as intense as rendering video but definitely more challenging than most games) three to four times as fast as my desktop i9, and after almost 2 years, I have yet to see it reach 40°C. It’s got some hefty fans that simply never have turned on yet, as far as I’m aware.
