Minimum processor state in power plan

Hi All

 

What will the minimum processor state do if we set to 5% in balanced power plan(Which is already set)

 

1. Will the CPU lower the Power & Voltage to 5% when its Idle?

2. Will it affect under heavy load. I heard setting the 5% min state will affect the performance regardless of 100% max processor state?

3. Will minimum processor state will be active when CPU will be under load for heavy application?

 

And in High/Ultimate power plan, Why the CPU min state is set to 100% by default.

 

1. Will power and voltage always be at 100% if the CPU is at idle?

 

I just want to know in details. When should we set min processor 5% and 100%? In which scenario? Do we really need min processor state to 100% (even while playing games)

 

I guess it will increase just electricity bill regardless of no performance boost

Hello Rishav, 



Thanks for your patience. I will respond to your questions:


1. Will the CPU lower the Power & Voltage to 5% when it is Idle? 

  • A/ The default minimum processor state value in Windows 10 and 11 is 5%; however, Intel cannot confirm that will be a permanent number, it can fluctuate based on what your system is running (what is in the background)

2. Will it affect under heavy load? And, 3. Will the minimum processor state be active when the CPU will be under load for heavy applications?

  • A/ Numbers can vary and increase under a high workload. 

4. Will power and voltage always be at 100% if the CPU is idle?

  • A/ There is no exact value that I can provide you for each processor. The processor has a few internal voltage regulations (FIVR, Digital Linear voltage regulator(DLVR) to support internal power rails. In each processor datasheet Technical Resources: Intel Core Processors there is a section called"electrical specifications" You can see average voltage ranges and specifications and understand how volts work on the CPU depending on different stages and based on Intel technology. 


Bear in mind that these ranges will depend on system requirements and those are average based on tests, not necessarily exact values.



If you have any questions, please let me know.
