I have a old HP Elitebook with 8GB ram with Windows 10 and even on Windows I don’t notice slowdowns for daily tasks. Yes the machine swaps but because of the SSD you don’t notice much performance decrease. However, because it’s constant swapping the lifetime of the SSD will decrease and that’s exactly the problem of 8GB machines these days. Yes the machine stays fast (Windows or OSX it really does not matter) but there is extra load on the SSD.

Don’t believe Apple marketing bullshit that 8GB is enough because of the “super duper advanced memory management” of OSX. If it really was enough then Apple would not release MacBooks with 16+ GB ram. The only reason that the 8GB MBP still exists is to sell more 16+ GB machines.

What about Windows 10?
