  This is still one of the most trusted sources for low-level optimization!

  uops.info is also very handy for x86 ( https://uops.info/table_overview.html ).

  But if you are just starting, those may be a bit overwhelming. In that case, check out the official intrinsics guides for x86 from Intel ( https://software.intel.com/sites/landingpage/IntrinsicsGuide... ) and a separate one for Arm ( https://developer.arm.com/architectures/instruction-sets/int... )

  I should point out that this has been posted [1], but not for the past half decade, long enough to need another PSA :)

  Too bad most people use Javascript frameworks for desktop development.
