Intel Meteor Lake-S CPUs will use the LGA 1851 socket

Intel CEO Pat Gelsinger highlighted upcoming products in the client and data center fields and shared next-generation chip production and process development during the third-quarter 2022 earnings call. Among them, the desktop Meteor Lake CPUs will be taped out in the fourth quarter of 2022, and the Intel 4 process it uses is moving towards mass production in an orderly manner.

According to Wccftech, Intel’s internal chart has been obtained, and the specific details of Meteor Lake-S and Arrow Lake-S have been learned. Intel is preparing a new socket called “V” (LGA 1851), which will be used by at least two generations of desktop processors, and is similar in size to the existing LGA1700 socket, more pins will be available to add support for new features.

Raptor Lake was Intel’s last single-chip desktop processor before it adopted a modular design. The latest news indicates that Meteor Lake-S will reduce the number of Performance Cores while retaining the same number of Efficient Cores, meaning the maximum number of cores is 22. The full configuration list 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
Meteor Lake-S uses the second-generation hybrid architecture technology, P-Core will enable the Redwood Cove architecture to replace the current Golden Cove architecture, and E-Core will use the Crestmont architecture instead of the Gracemont architecture. It adopts the Tile design and will have four different modules, namely the computing module, the SOC module, the I/O module, and the GPU module. These modules can be fabricated at different process nodes, then stacked, and then interconnected using EMIB technology and Foveros packaging technology.

In the computing module, SOC module, I/O module, and GPU module of Meteor Lake-S, the computing module adopts Intel 4 process, and the SOC module and I/O module adopt TSMC 6nm process. The GPU module uses TSMC’s 5nm process. According to the past, the GPU of Meteor Lake-S will be the Xe-LPG architecture to replace the Xe-LP architecture since the 11th generation Core, which can meet the requirements of DirectX 12 Ultimate. Since the graphics card has at least 4 Xe cores, that means there will be 64 EUs, which is two fewer Xe cores than the lowest-end Arc A310 graphics card.

Replacing Meteor Lake-S is Arrow Lake-S, the highest configuration is the same as the current Raptor Lake-S, with 8 P-Cores and 16 E-Cores, a total of 24 cores. The full configuration list includes:
  • Arrow Lake-S 24 (8P + 16E) / 4 Xe Cores / 125W TDP
  • Arrow Lake-S 24 (8P + 16E) / 4 Xe Cores / 65W TDP
  • Arrow Lake-S 24 (8P + 16E) / 4 Xe Cores / 35W TDP
Compared with Meteor Lake-S, Arrow Lake-S mainly adds 2 P-Cores. It is not clear whether the Xe core will adopt a new architecture. Intel will also introduce a new process. The computing module uses the Intel 20A process, and the GPU module uses the TSMC 3nm process. It is expected that the SOC module and I/O module will follow the TSMC 6nm process. In addition, it was previously reported that the P-Core of Arrow Lake-S will use the Lion Cove architecture, and the E-Core will be the Skymont architecture, which is still uncertain.
