Higher vcore makes less performance?!

Islam Ghunym · October 28, 2020

So I have my hands on an old CPU which is the intel pentium D 945 as I remember. It is 2 in 1 CPU uses a 95W of power on a Gigabyte EP41-UD3L motherboard.

It is a quite old stuff and I decided to see how well this would overclock and what are the possible gains out of it.

What I noticed is that the performamce of this CPU in general in every bench drops down by increased Vcore. This looks strange to me because this CPU has no thermal throtling and it actually runs at max clocks all the time, but why performance drop is something I didn't guess yet so hopefully I get an answer here.

there's a difference between thermal throttling and power throttling, it's likely you're overheating the VRMs or simply asking too much out of it

also, TDP ≠ power consumption

Nope, power goes up with vcore going up and there is no power limit scenario and my VRM temps are too low + I never said TDP = Power consumption.

Be sure if the answer is that simple I wouldn't be asking ☺
