Just trying to get my head around this and this is only a example of a specific cpu. I was looking at the Intel i9 7920x and i9 9920x both are 12 cores but one has a TDP (Thermal Design Power) of 140W (7920x) and other one has a TDP of 165W (9920x) both are skylake-x 7th and 9th gen. My question is if both are overlocked to the same frequency and same voltages are applied say 4.6ghz at 1.23v for both obviously everything else stays the same cooler, case etc..... wouldn’t the 7920x run more cooler because of the 140 TDP ? the only thing the 9920x has more is the cache which is 19.25mb compared to the 7920x which has 16.50mb. I mean what are the real advantages except for more heat?

Same cores BUT higher TDP, more heat?

The i9 has a higher base frequency which is why the TDP is higher as the two are related.

As for your supposition, I think it's false as TDP doesn't work that way.
If that i7 had the same base frequency as the i9 the TDP could be higher or lower than that of the i9.
Too many factors to consider such as are they using the same 14nm version and the same chip binning.
