No, they have only about 60% the integer performance of a P-core running 1 thread. Where the E-cores are faster is to load them instead of putting a second thread on a P-core.

My point is that what you're talking about is a low-clocked, in-order Larrabee core. You cannot compare that to a high-clocked out-of-order, general-purpose CPU core. Even 2016 was too soon for Intel to deploy AVX-512 on general-purpose cores @ full width. It was a big mistake, due to all of the clock-throttling problems it caused. Possibly 10 nm ESF (AKA "Intel 7") is the first time it really makes sense.
