> RAM and fan has nothing to do with it, the cheapest low-end Windows laptops can do this with ease, it doesn't stress the RAM, CPU or GPU at all. - M-series uses unified memory, the ram does in fact matter. - Heat also matters, because throttling. The Air uses a fanless, heatsink system. - Whatever cheapest low-end PC you’re imagining is not fanless and not running an external 6k monitor at 60Hz. - None of those systems are optimised to maintain performance while possessing an 18 hour battery life. None of those even have an 18 hour battery life. The Air serves a clear market segment. It’s their entry level laptop, the problem isn’t the laptop.
