Performance impact of Android Image x86 Atom vs x86_64 Atom on x64 host

Question

I am using Android studio for android development and in the SDK manager I can see different flavors of System images. My question here is particularly about x86 Atom Image and x86_64 Atom image.

Also does the x86_64 Image mean the instruction set within the android is 64 bit or does it imply that this particular x86_64 image should be used on x64 bit host/development environment.

If I am on an x64 intel computer I can use both of the images, I wonder what difference will either of the images will have if any when I run them on x64 host/development machine.

Answer 1

I've measured it and x86 is 10% faster than x86_64:
