For >99% of people looking to compile code or render video on an M5 Laptop they are interested in the wall-clock time, running bare metal, assuming all IO is to a fast NVMe SSD, and even a large job will only thermally throttle for a bit then recover.

Most people looking to optimize Epyc compile or render performance care about running inside VMs, all IO to SANs, assuming the is enough work you can yield to other jobs to increase throughput, and ideally near thermal equilibrium.
