Undervolted 5700X3D uses less power after sleep?

Hi I just got a 5700X3D which i'm using on an old MSI B450M PRO-VDH MAX and undervolted it with -20 all cores in curve optimizer (PBO limits auto) and i noticed a small quirk when running cinebench r23, the CPU uses a package power of around 90w in the multi benchmark when i boot the PC up and if i let the PC sleep once it suddenly uses 8w less in the benchmark so around 82w which is also far below the 3600x i had bevore.

Temps are generylly pretty great 65C max and around 30 idle, i don't think it's a display error since it's also 2 or 3C less and sometimes gives a bit higher score, so it's not that i want to complain i just thought it was a bit stange that's all.
