Look at your own post maybe…

What Jigger is referring to I believe here is that the E cores are clustered into micro-meshes of 4 which have a single connection to the ring bus, so scaling them up to replace P cores/hyper-threading doesn't really work - as then you get the worst of ring stop latency on top of the negatives of best case latency from the mesh side.
No idea why they've decided to make such a mess of discussing it though.

Which makes sense, except there doesn't seem to be any actual source (Intel or otherwise) that confirms that the E cores definitely are using a mesh (or ring or crossbar or indeed anything else 
)
)
Skylake release quickly made Haswell E obsolete though - as Skylake's IPC was noticeably higher and clocked higher thanks to a better process. Think it was less than a year that Haswell-E had the spotlight.
What’s your point, new stuff is better? X99 was a great platform, could even drop a 18 core Xeon in. I used it 7 days a week for > 7 years. P.S: Skylake sucked

I'm assuming most communication between them is via the shared L2 cache anyhow.
EDIT: Best I can find on that:

Which suggests the quad core clusters don't have an internal mesh topology.

Yes the 14700k is basically the 13900k for less money.

My point was pretty obvious, X99 was quickly eclipsed for gamers and those using productivity workloads that were lightly threaded, as Skylake had better clocks and IPC. Pretty average/sub standard platform to be eclipsed so quickly after release IMO.
The IPC change was like 2-4% (typical for Intel at that time). X99 was a great platform for users that do more than just game, and it was great for games too. Considering it was also priced not to far above the normal desktop stuff, it was a no brainer for me, 40 PCIe lanes, Quad Channel RAM (8 slots), lots of PCIe slots on the mb’s(that worked without disabling other stuff). Haswell E also overclocked well (4.2-4.6Ghz).
Are any of these CPUs released yet?
I am currently looking at an HP all in one system which comes with the Intel Ultra 5-125U
Under specifications it says
Processor - Intel Core Ultra 5
Processor Speed - Intel Core Ultra 5-125U (14 Cores, Up to 4.5GHz, 12M Cache, 18T)

Maybe but wont know for sure until its release

125U is Meteor Lake

Another hype train is danger of derailing like the Zen5 train before it.
Current estimates are all over the place still though with ST anything from 3% to 20% although the strong possibility of clock regression might explain some of that as being IPC vs ST score.
As for MT, Skymont looks very good but dropping HT does not. Skymont cores aren't that small anymore so the 8P/32E rumour seems very unlikely IMO. In fact, even 8P/16E might be too big long term if the E cores get even bigger.
Worst rumours ATM as far as I'm concerned is that some of those ES samples are running at way over 200W at stock again.
