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.

It depends on task. In games my CPU is only 6,2% average slower than 13900K and is taking like half of energy, 7800X3D is squishing 13900K taking like 88W at max. Yes, it true, Intel CPUs are performing better, but at cost of insane energy usage.
Curious why i have not seen any Xeon with E-Cores :)
I really hope Intel doesn’t take 20 years to match amd on power/performance ratio. As costumers, we really need good coopetition

DDR5 on raptor lake only seems to work in gear 2 though, even at lower settings -- at least on my current mobo.
X3D are an outlier. Weaker than the regular chips in applicative, but much, much more efficient in gaming, because the design is just really optimized for gaming. Even the classic Ryzen seems massively inefficient versus their 3D counter part in gaming. But X3D chip are only attractive to gamers, other users will find a better price/performance with the classic Ryzen.
The comparison between a 13900k and a 5800x3D is only a thing because Intel doesn't sell a gaming focused chip, but the i9 happens to be the fastest intel chip for gaming. Still, those two products are meant for two radically different target. What's a 5800x3D is going to accomplish against the i9 in applicative ? And a pure gamer will ultimately benefit more from a 13600k/strong GPU combo. The i9 only give you 2% more performance.
Using the i9 as your reference in a pure gaming scenario is a bit disingenuous. Even in intel own line-up that's the least efficient CPU for gaming. The 13600k make it look bad in that specific scenario, just like it also make the 7900x/7950x looks bad in gaming if we are going to cherry pick.
Intel is indeed less efficient, just not as much as you try to paint it, once you look at the bigger picture. Look at the graphs on TPU, and you will see a few games in which a 13700K use less, or as much power as a 7900x.
Zen 2 for example had an exclusive bug in Maya:
AMD Ryzen and Unfold 3D Maya problem - Autodesk Community - Maya
I myself had an issue with shutter encoder who works well 1 out of 2 time with my 3700x, but works just fine on my intel laptop. I've seen a professional 3d artist say that he's sticking with Intel, even if it's slower for peace of mind. AMD still need to work on the mindshare aspect, to convince people that "it's safe to switch". I've heard a loooot of people (especially people outside the tech community) who don't see them as a safe option just yet
with a bit of tweaking like i did to my 12700k it should run fine on a good air cooler.
my 4090 is starved for more cpu power so a 14700k might not be much of an uplift in that sense.
by the time a 5090 is out we have a 15700k so why does this generation exist?
1 P-Core (With HT) R23-> ~2500
4 E-Cores -> ~4000
60% more performance for the same area
