That’s the problem. They are not massively parallel. In fact, don’t use more than two cores efficiently. Therefore the i9 will perform better than Xeon due to higher clock speed with lower cores. Also, this software uses Intel MPI libraries. A new i7 runs it 30% faster than a new Ryzen 7 with same clock speed. So Intel is tweaking their compiler for their processors.
