Best SmBios for energy save

Question

I remark that when I change smbios my CPUPackageCore change too,

for example when I use MacMini6,2 ?my minimum CPUPackageCore in idle is 0,14W

whereas others like MacBookPro 9,2 my minimum in idle is 0,21

I remarked too a increasement of batery life in macmini6,2.

?

my question is what is the best smbios for better energy save, please?

The best SMBIOS isn't chosen based on energy saving, it must simply be the most approximate to your system. In my case a laptop with a 2nd generation core i5, so I use MacBookPro8,1 because it has a 2nd generation core i5.

What is your processor? If it's an Intel, search for it on Ark Intel, and your idle frequency should be half of your base frequency. This frequency related stuff is defined on the SSDT, so the best option for energy save is having a custom one.

My proc is 3rd Gen Ivy Bridge i5-3230m, I have a custom ssdt with ssdtPRGen and my based(non turbo frequency) is 2,57GHz, my idle frequency is 1,19GHz.

But I don't talk about my idle frequency but my idle CPU Package Core who is by Watt, is it related, please ?

It is related...

?

The lower the clock rate, lower will be the power consumption...

?

For example, using Macmini, you may reach more P-States than using MacBookPro SMBIOS...

?

Even in idle state, there are services running... This will consume more power to keep the clocks a bit higher...

?

I've already saw, Ivy Bridge users with lowest clock of 800Mhz, this will consume much less power than yours

1.2Ghz....

?

So, let's assume that using Macmini SMBIOS you have...

?

12 > 14 > 16 > 18 > 20 > 22 > 24 > 26Ghz

?

And with MacBook Pro...

?

12 > 18 > 19 > 20 > 23 > 24 > 25 > 26Ghz

?

This gap between your lowest and next P-State will make you CPU consume more power (watts)...

How you've made your SSDT??? Could you attach your "clean" ACPI Tables extracted from

Windows, Linux or Clover and patched DSDT/SSDT here???

?

How you are checking your P-States???

I made my ssdt with?ssdtPRGen.app.

I check my P-State with AICPMInfo.kext

?
