The meltdown paper explains the same side channel race condition vulnerability exists on ARM and AMD CPUs. Their toy project shows all three architectures have the same flaw. However for unknown reasons it’s worse in Intel. They were not able to exploit the vulnerability to dump the kernel memory on AMD and ARM. So I find the whole “Intel you suck” really out of line. I would not be surprised someone clever will come and figure out a Meltdown style attacks which works on AMD and ARM CPUs. As Bruce Schneier says: “attacks always get better they never get worse”
