Hello, We are currently selecting a high-performance computer for this Chrono project. There are now three CPU options available:
1. AMD 7773X, basic Frequency 2.4GHz, Max Turbo Frequency3.5G ， 64 cores，with 2 pieces; 2. AMD 5995WX， basic Frequency 2.7GHz, maximum Frequency 4.5GHz, 64 cores, with 1 piece; 3. Intel 8380, basic Frequency 2.3GHz, maximum Frequency 3.4GHz, 40 cores ,with 2 pieces. What I want to know is whether the current Chrono software supports dual CPU mode. As a software developer, based on your experience, which of the three CPUs above is the best choice?
