That extra 8GB of RAM is probably doing a lot of the heavy lifting to make general use smoother. More RAM = less swapping to the drive when memory fills up (which on 8GB means ~5 tabs in a browser before it starts slowing down haha).
Left a comment as a reply to one of yours about the laptops themselves.
The way I can tell if a game does/should run on my PC is kind of a multi-prong approach
And then check protondb to see if it can run on linux (most likely will)
Integrated graphics may have some gotchas but the general rule I follow is “if it came out within a console generation, it can’t run that console’s games. Last gen can be serviceable. 2 generations back run pretty well.”
FWIW I think the Surface is the more powerful machine.
I wouldn’t bother with any 3D AAA that came out after ~2010 on the Mac and even then you’re looking at 720p 30FPS
The Surface looks like it might be a solid light indie game machine. I doubt it’ll struggle too much with anything 2D and may even be able to run late PS3/super early PS4 era (before 2015) 3D games at reasonable framerates.
I wonder how many of the best emulator devs 5 years from now will have started off out of spite because of Nintendo being cunts about emulation and Sony taking down the Bloodborne 60fps mod
