What is the differnce in AMD cpus that make them less effected by spectre/meltdown?

Surely AMD also uses similar technology such as speculative execution so why are AMD less affected ?

The Meltdown flaw is caused by letting a user-level program speculatively execute on supervisor-level data (which is a permission failure). Most processors (like from AMD) immediately stop executing past the failure, but Intel apparently doesn't check the failure occurred until later.
