Intel as part of its development process with industry partners and OEMs, allegedly released technical documents in a bare URL that's worded to confirm that its next desktop processor socket will in fact be the LGA1851. We've had some idea since June 2021 that LGA1851 will succeed LGA1700, but this can be taken as a confirmation. Although with a higher pin-count, the LGA1851 package will be physically of an identical size to LGA1700, with mostly identical socket mechanism, so the new socket could maintain cooler compatibility with its predecessor. The additional 151 pins come from shrinking the "courtyard" (the region of the land grid in the center that lacks pins and instead has some electrical ancillaries).

The new Socket LGA1851 platform is expected to power Intel's "Meteor Lake-S" and "Arrow Lake-S" microarchitectures. Whether "Meteor Lake-S" gets the 14th Gen Core branding is a whole different question. Leaked benchmarks suggest that 2023 will be a rather slow year from Intel in the area of desktop processors, and that toward Q3-2023, the company will release the so-called "Raptor Lake Refresh" processors. These chips are likely built on the same LGA1700 package, and as we've seen from "Coffee Lake Refresh," could warrant a new generational branding to 14th Gen Core (as CFL Refresh formed the 9th Gen Core). Intel could increase clock-speeds, E-core counts, and other process/packaging-level innovations to segment these chips apart from existing 13th Gen Core "Raptor Lake." LGA1851 processors like "Meteor Lake" could debut chiplets for Intel, as these have their CPU cores, iGPU, memory-controllers, and uncore components, spread apart on chiplets built on various foundry nodes.

That being said meteor lake desktop is going to be a dumpster fire with the rumor of only 6 P cores instead of 8. That'll go over well with the peanut gallery. Meteor lake mobile with a 128/192eu GPU is far more interesting.

Intel knows the socket tension is a problem, why not fix it with the new socket?

Gamers don't need 6+ P cores. I'll trade 2 cores for DDR5-12000

I mean If rt gets more and more the norm then yeah.....you do, what I more wonder is, will the refresh work on 600 series boards and will it be ddr4 compatible?

Personally I think it's not too bad with 3 processor ermm families? Coming to 1700 and if indeed the socket cooler compatibility remains the same and maybe also the retention plate thats not that bad imo

Aha, I am running 5900X on B450! Oh, look! Intel has a new socket!

If anything to be surprised of is the RL refresh, not the new socket.
It will, if true, counter some of the 'dead-end platform' argumentets, even if for just one more year.

So an KSS suffix is coming?

I might consider treading 2P cores to 8E cores. They are little magic.

I'm more surprised by a Raptor Lake refresh. It appears Intel is looking to get another generation out of that socket. I wonder if it'll be compatible with z690 or they'll pull another Coffee Fake again.

Good question. Maybe it will use the new socket even though it's still just a raptor lake.

Because Meteor Lake is delayed. They are struggling big time with FPGA fabric, the new node Intel 4, and chiplet design. RL has to soldier on another year at least until early 2024.

I still wonder if they'll continue support for DDR4 or drop it and at the same time if they switch to new socket with Raptor Lake refresh and continue to use that same socket for Meteor Lake and Arrow Lake plus they have a bit of a excuse to switch to a new socket anyway with the socket tension issue with LGA 1700.

Gamers need cache and at least for Intel, more cores = more cache (cash)
