I have a Macbook Pro with a i9 Processor and running Macos Catalina. I run CPU extensive tasks daily, but it never utilizes 100% of the CPU. I use Intel Power Gadget to check out my CPU performance. Screenshot of Intel Power Gadget Utilization never reaches 100%. Yet when I run the Cine-bench Bench-mark it reaches 100%. Can I know why this doesn't happen when I run any other regular app which must consume 100% utilization in order to actually run faster. I also made sure the software I am running is optimized in a way it can acquire many cores as possible. Hope you can share any configuration files that must be changed to in order for all processes capable of utilizing 100% of the CPU.

  • "I also made sure the software I am running is optimized in a way it can acquire many cores as possible." I assume the process(es) you're running completely reside in user space. The kernel scheduler is ultimately responsible for distributing CPU resources among threads. A process that lives in user space does not have the ultimate say in how many CPU resources it can absorb for a given chunk of time. So what do you really mean by "optimized?" – Synoli Nov 6 '19 at 11:14
  • Are you sure that the process you are trying to run is sufficiently compute-intensive to use 100% of the CPU? It must be multi-threaded in a way that does not cause one thread to ever wait for a resource held by another thread, it cannot access the network or file system, etc.? – jalynn2 Nov 6 '19 at 18:56
