Why is AMD Ryzen 7 CPU so slow in Fitter in Quartus Prime Lite 18.1?

Hi,

​

We appreciate for the thread submission here. This is really an abstractive question to be address by making comparison in terms of CPU's Core's as the focus. Each units of CPU listed in the photo attachment has the own best performance and also the limitations.

This more on performance bench-marking where more requirement of your systems used need to taking into consideration in terms of memory, hardisk space, speeds (RAM/HDD), processing thread configured, cache and so on.

Beside this, the operating system used also one of the factors along with the utilization running on the background. There are several configuration set you can try out to getting better performance using Quartus as below:

1. How can I improve the compilation time performance of the parallel compilation feature in the Quartus II software?
