Sometime it is really frustrating because I can't use the full potential of my Mac. This performance drop occurred back to the time I upgraded my OS from High Sierra to Mojave.
Therefore I believe there is something limiting the CPU performance.Īs I didn't recorded the CPU power draw before, and I noticed this issue recently, I wonder if Apple is lowering the CPU performance of older Macs?Īn early review article on Internet ( ) even said that the CPU is limited to 32 Watts, which is higher than the Intel rate.
The CPU on my MacBook Pro 12,1 (i5-5257U) would only use up to 18 Watts of power and the system total power usage is well below 35 Watts with a 60 Watt PSU connected and CPU Core temperature under 85 Degrees C (fan speed 80%) while running Cinebench R23. I already posted this on Apple Community but it seems no-one saw my post. I am pretty new here, because of some strange performance issues of my Mac I decided to write here asking for some help.
