Intel Core i7-14700K has an 8P+12E Core Configuration
The upcoming Core i7-14700K "Raptor Lake Refresh" processor has a core configuration of 8P+12E. That's 8 "Raptor Cove" performance cores, and 12 "Gracemont" efficiency cores spread across 3 E-core clusters. Compared to the i7-13700K, which has been carved out of the "Raptor Lake-S" silicon by disabling 2 out of the 4 available E-core clusters and reducing the L3 cache size to 30 MB from the 36 MB present; the i7-14700K gets an additional E-core cluster, and increases the shared L3 cache size to 33 MB, besides dialing up the clock speeds on both the P-cores and E-cores in comparison to the i7-13700K.
The processor likely has a P-core base frequency of 3.70 GHz, with a 5.50 GHz P-core maximum boost. In comparison, the i7-13700K tops out at 5.40 GHz P-core boost. An alleged i7-14700K engineering sample in the wild has been put through Cinebench R23, where it scores 2192 points in the single-threaded test, and 36296 points in the multi-threaded test. The processor also scored 14988.5 points in the CPU-Z Bench multi-threaded test. Intel is expected to release its 14th Gen Core "Raptor Lake Refresh" desktop processors some time in October 2023.

As for AMD TDP has never been equal to power consumption since Zen debuted, don't remember about Dozer & don't care either! From the link the other poster shared, these are power consumption numbers ~
Needless to say if you do go back to the old BIOS, that'd be at your own risk so take care about that.
(follow up question)
So where are 12th and 13th (and 14th) gen cores used in server farms and how is that working out for Intel? In the efficiency conversations this element doesn't seem to come up much in discussion.

This would probably top the efficiency charts next year!

Intel sapphire rapids are the latest intel server cpus and they use 12th gen cores. They dominate in AI workloads due to on chip accelerators but are kinda average or even flat out bad on other workloads.
Basically, the reason amd dominates in servers is the same reason their CPUs aren't that compelling in desktops. The ring bus intel is using is just better for home users, consuming much less power on idle and light loads which are the majority of what home users do with their pcs. My zen 3 chip consumes 30 to 40w just browsing the web while intel just needs 5. Ring bus superiority.

I also have a 7700X, but I can't test it now, as I'm about 1,500 miles away from home until the end of next week.
I also have several other CPUs besides the two that I've mentioned, they're all Intel (various 1st, 4th, 7th and 11th gen Core). I think that's exactly the case, although without having a 12th or 13th gen Core i7 at hand, I can't know for sure.
A 12900k with 2 P cores off scores 17988, with the full 8+8 configuration 20250.
13th gen should be 10% above that I haven't tested every possible power level, so I can't say yes, but in general -- I don't think it's' a close contest in any power level. For starters, with the i7 at 100w, it scores way way higher than what is possible for the R7 to achieve, even with ln2 cooling. So for anything above 90-100w, the i7 demolishes the R7. Below that range, I don't see the R7 doing much honestly
For example, my 12900k @ 125w scores 25k to 26k (that's with undervolting) and 24k at complete stock. No R7 on planet earth, no matter how much power you push through it can get that score.
I remember while I had the 7700X installed, I saw barely any difference at lower power limits.
But still, like for example, 12900k @ 35w = 15200 cbr23 score. Don't think a 7700x can match that.. in fact I don't think any CPU besides 13th gen Intel can match that.
