Question Question about P-cores versus E-cores

In an Intel CPU with performance cores and efficiency cores, suppose you are running two computationally intensive tasks, How would performance on two E-cores compare to running them hyperthreaded on one P-core?

In the server world the all E-Core Xeon is said that each core is like a single thread of a P-Core. Overall the E-Core is about as fast as a Skylake CPU of equal clock speed.
