Intel's website has content not accessibly available for public viewing, but ComputerBase located information on the sitemap disclosing information regarding Intel's next-gen Meteor Lake desktop CPUs which will get support on the latest LGA 1851 socket. The data lists information linking to a new CPU socket for the Meteor Lake desktop lineup & verifies the support for LPDDR5X-7500 memory.
Intel LGA 1851 Socket For Meteor Lake-S Desktop CPUs Confirmed Along With LPDDR5X-7500 Memory Support
The new LGA 1851 socket will house the new Intel Meteor Lake-S desktop CPUs. The socket is the exact dimensions as the LGA-1700 socket, with one slight difference. The IHS of the socket protrudes higher than previous sockets, which could ensure adequate room for Intel's new multi-tile technology. Another reason could be to avoid issues seen before with Intel's Alder Lake CPU deflecting and overheating due to strain from warping.
The information in the sitemap shows the following information, with a few highlighted areas showing the mentioned new socket.
There is also some valuable information from some of the links in the image above, such as (via Videocardz):

With this information, we can conclude that Intel has verified the existence of the new LGA 1851 socket and the preparation that it will be compatible with Meteor Lake and Arrow Lake desktop processors, as signified by the "S" labeling used. Also, with the information listed, we can conclude that the company will support LPDDR5X-7500 memory. Intel's Arrow Lake CPU lineup is anticipated to support LPDDR5X-8400 memory and DDR5 UDIMM and SO-DIMM versions with support for ECC.
Intel 14th Gen Meteor Lake Desktop CPU Lineup (2024)
Intel's 14th Gen Meteor Lake-S Desktop CPUs will take a step back and reduce the number of P-Cores while retaining the number of E-Cores. The lineup listed in leaked charts includes five different SKU configurations with the top variants featuring up to 22 cores in a combination of 6 P-Cores and 16 E-Cores. The P-Cores on the Meteor Lake CPUs are based on the brand-new Redwood Cove architecture while the E-Cores will utilize the Crestmont design. Both of these are new and improved architecture as reported by Coelacanth-Dream a few weeks back.
The full list of configurations includes:
- Meteor Lake-S 22 (6P + 16E) / 4 Xe Cores / 125W TDP
- Meteor Lake-S 22 (6P + 16E) / 4 Xe Cores / 65W TDP
- Meteor Lake-S 22 (6P + 16E) / 4 Xe Cores / 35W TDP
- Meteor Lake-S 14 (6P + 8E) / 4 Xe Cores / 65WTDP
- Meteor Lake-S 14 (6P + 8E) / 4 Xe Cores / 35WTDP
In addition to the SKUs, we also get to learn that all SKUs will feature at least 4 Xe Cores for the iGPU and that's going to offer 64 Execution Units or 512 ALUs. That's 2 Xe Cores less than the DG2-powered Arc A310 graphics card which is the lowest-tier discrete board in the family but an integrated GPU with this much capability will be on par or even better than the RDNA 2 iGPU on AMD's Ryzen 7000 Desktop CPUs. Only the top die configuration will have a 125W "Unlocked" SKU range while the rest will come in the standard "Non-K" and "T" series with 65W and 35W TDPs.
The one thing to note here is that the 14th Gen Meteor Lake CPUs will only be available in up to Core i7 parts and there will be no Core i9 part due to the lowered core count. The CPU will retain the Intel 4 (CPU) + TSMC N5 (tGPU) + TSMC N6 (SOC) process nodes.
