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 (2 e-cores is equal to 1 p-core in performance). Overall the E-Core is about as fast as a Skylake CPU of equal clock speed.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?
On older Intel CPUs, I used to believe that Hyperthreading increased perormance by roughly 20% in some apps, but I think I saw somewhere that Intel is getting rid of Hyperthreading on some modern CPUs.hyperthreaded on one P-core
That is correct. The newest Arrow Lake CPUs do not have hyperthreading on them anymore on the consumer side.Intel is getting rid of Hyperthreading on some modern CPUs
