Verify CPU specifications
I’m confirming the Intel G3930 is indeed a 6th generation CPU. Let me know if you need more details!
It's not Skylake. You can find more info in Intel ARK.
It appears on the same roster as the other 7th generation processors.
Yes, a CPU with Skylake architecture is generally considered to be around the 6th generation of processors.
For Celeron models, use G3900 or G3920. For Pentium, select G4400.
