If indeed the supposition that the less variable and more predictable performance of the ARM CPU mattered for the observed system behavior is right, then using an x86 server CPU, e.g. an Epyc CPU, instead of a desktop CPU would provide similar benefits to the ARM CPU, because server CPUs have a lower range of variation for the clock frequency and they use less aggressive clock frequency boosting policies. This could be tested even on the existing desktop hardware, by disabling "Turbo" in the BIOS settings, so that the Intel CPU would run at the base clock frequency, providing a lower, but stable and predictable performance. |
