Anybody who cares about performance on multi-threaeded workloads.

Wrong.

Much more in desktop version of Alder lake

Anybody who cares about performance on multi-threaded workloads.

Taking advantage of more than 8 threads does not require the workload to be embrassassingly parallel.

Medium cores server a very useful purpose of improving throughput performance.

Often you have one thread where you want maximum performance, and the factor of the computer does not affect that. Not wanting at least single big core for that is pure stupidity or ignorance.
