Buying a new CPU, Motherboard? I could just do a video on what is Amdahl's Law, but with all the new CPUs coming out with more cores, more threads and higher CPU Frequencies. It's time to take a page from Enterprise Computing, because "Toto, we aren't in Kansas anymore". The rules you learned back in the quad core days are out the window now. And you need to understand how to predict and measure performance to get the most out of these new CPUs. Sadly, I do not have a Windows machine to show you but you can run GeekBench on it to get the measurement you need Serial processing means strictly sequential, without overlap of the successive processing times on objects or distinct subsystems. In a standard type of serial system, each object takes the same average amount of time to process and the next object begins processing only when the previous one is completed. Parallel processing signifies simultaneous processing on several objects or subsystems at the same time, however processing may finish on different objects at different times. BTW, Neural networks do not predict well using Amdahl's Law either, as cores are added to a neural net, the system will grab more data, similar to the HPC problem Gustafson points out.
