PostgreSQL on ARM-Based AWS EC2 Instances

I think what they mean is that there are enough non-CPU differences that you can't make this an accurate comparison. That being said at the end of the day the ARM instances are cheaper and better performing—whatever the reason may be.

But the non CPU differences (compiler / linker / OS optimizations), number of drives etc - all seem to favor x86?

The SSD is clearly different. Are there other differences, or are people just assuming?
