No. It is not why. As I said, show me. Prove it. If you SAY this is how it is, there must be proof and if there is proof, then show it to me and I will agree with you. Otherwise, stop saying it. Period. It's nothing against you. It is simply, well, we have a policy that has stood since the beginning of this forum and that is, if you can't prove it, it is Fing BS. So, show me the money, or don't.
And so far, you haven't. Well, you've tried, but it's definitely not conclusive. Cinebench? Don't make me laugh. But even there, if you look at the MUCH more trustworthy Anandtech results, it's not even in the ballpark. FULL multi suite comparisons only please. ANY CPU can beat the piss out of another CPU in some specific benchmarks. Doing it across the board, is completely different. Granted, I 100% agree that the primary benefit of any of the x3D processors is gaming, and the most recent ones don't get even as much of a clear win as they did last generation, however, to say that the multithreaded performance, in general, meaning specifically across the board, is double, is ludicrous and we both know it.
Here are the REAL, FULL suite results, and nowhere is there anything even remotely approaching twice the multithreaded performance. In fact, it's so far from it that your premise is entirely laughable. Sorry. Again, it's not really against you, just against the misguided idea of what you are trying to say. I know you want to help, that is not in doubt, but you should reconsider some things you take for fact when in fact they are not.

And your statement about "when you are not comparing fully MT workloads the 14700k won't score double, but it's twice as fast" makes absolutely no sense, at all, at all, at all. Period. If it does not score double, then it IS NOT twice as fast. Again, period. Stop trying to use Trump logic to make points that simply don't exist. It's BS and this kind of reaching really looks bad on somebody that ought to know better.
And for the record, Blender uses, FULLY, more cores and threads as they are available, than almost any other piece of software that exists, and the 14700k definitely beats the 7950x3d but it's like closer to 17% better and if you look CLOSELY at the charts, which I trust WAY more than I do other posted benchmarks, you will see that even in Cinebench R23, which you MAINLY referenced, it not even close to their results. It's literally only 4% faster in the multithreaded Cinebench R23 results so your convictions are skewed beyond the realm of believability, for me at least.
