I5 4460 boots slower than Pentium G3420

[Six66]

I have replaced my G3420 with i5 4460.
I have recorded boot speed on Windows 10 (several measurements).
i5 average is 16 seconds, while the weaker Pentium booting time is about 10.5 seconds.

Anyone any ideas why is this so?

I assume that's the only thing that changed?

I can see no good reason for it. The i5 is not slower than the Pentium in any metric, but boot time doesn't have a lot to do with the CPU anyway; A long time back I wondered why Windows98 booted so much faster on a Pentium III 500 than on my Athlon 1400 - the difference was 3-4x.

Yes, I have changed only the CPU. I don't care that much about boot time (both are good), I'm interested in the phenomena why this is the case.

I'd check to make sure you're seeing all 4 logical processors in task manager. Chances are good Windows is only running on 2 cores. This is usually fixed by uninstalling the CPU from task manager and allowing Windows to rediscover it.
