Performance Benchmark Amd Ryzen 2400G vs 5600G

My Promox server hit to performance issue.

Therefore I have decided to change my old CPU AMD Ryzen 2400G (4 cores, 8 threads) running on Promox to AMD Ryzen 5600G (6 cores,12 threads). 

Before i made a CPU swap, I did a benchmark & below is the result.

Tool: Sysbench

sudo apt install sysbench

AMD Ryzen 2400G


sysbench cpu --threads=8 run

Result: Refer to event per seconds. Total 7804.45

AMD Ryzen 5600G


sysbench cpu --threads=12 run

Result: Refer to event per second. Total 33266.27

The highest is the number of events per second, better is the CPU performance. 

The winner was AMD Ryzen 5600G (as expected) by 4x
