i removed tdp from my post, I see you saw it before my edit (look in history, I sometimes miss revert).
Both will boost to max speed if given chance, and the f is 200mhz faster at max. which suddenly changes the ball game

Who wins exactly?
The f wins. For one thing, if you wouldn't ignore it, I listed cost right there at the beginning, as it's my primary concern. I only allotted myself so much for this, which is the amount of the CD that I created 18 months ago and the interest it accrued (which I mentioned here at the time). On Amazon, which gives me a 5 percent discount so I bought everything there, the F was $155 cheaper. Who wins exactly?
But furthermore you are incorrect on which is most power efficient. How did you decide that the 9800x3D doesn't have an increase in power during heavy usage? That's nonsense. Instead of the 120 above, it should be 162, and the 120 is as low as it gets. Given that the computer will rarely be under heavy load, I'd say that the 14700f uses less power over the course of a year, and every single tech spec site says the same thing.
As to why it recommended a 1000 watt PSU to me, I believe that when I wrote this up, that I was incorrectly remembering what it said, and I was actually remembering when I was goofing around and put the 9900x3D in. I put in a bunch of AMD CPUs, so it's not strange that I misremembered, but sorry for the confusion.
I asked CoPilot this question about annual power usage, and it gave me the exact same answer as PassMark and everyone else. it said this:
______
The
AMD Ryzen 7 9800X3D would consume more power overall compared to the
Intel Core i7-14700F in a desktop PC that is never turned off.
- Estimated yearly power consumption for the Ryzen 7 9800X3D is 87.6 kWh, whereas the Intel i7-14700F consumes 47.5 kWh.
- This translates to an estimated annual running cost of $21.90 for the Ryzen 7 9800X3D, compared to $11.86 for the Intel i7-14700F.
So, if power efficiency is a priority, the Intel i7-14700F would be the better choice. But if performance is your main concern, the Ryzen 7 9800X3D might be worth the extra power draw. What’s your main priority—efficiency or raw performance

Notice that I included that last paragraph? If you had found similar information in favor of Intel, I doubt you would have included it. But I also mentioned, previously, that the single core advantage of the 9800X3D would win out. But even in this paragraph, as all the tech sites confirmed, the 14700f is more efficient, which since the performance of the two is similar, makes it a better buy.
