Here we will run some targeted benchmark tests to gauge the raw performance/calculation speed of the CPUs.
SuperPi is a very popular program for testing single threaded performance by calculating digits of Pi. You run it by setting the length of the test and the score is time-based at the end. Performance is judged by how quickly it can complete the task you assign.
The MSI MPG Z390 Gaming EDGE AC did good falling just short of the other two boards but well within such a slim margin its tough to rule it out.
WPrime is very similar to SuperPi but is a multithreaded program which you can assign the number of threads that work on the problem and you get a time-based result on how long it took for the CPU to crunch through the task you assign.
WPrime sees the MSI MPG Z390 Gaming EDGE AC fall in the middle on the longer test just barely besting the ASUS board but once again margins are slim.
