Embedded World 2024 in Nuremberg offered exciting insights into the future of embedded systems. In addition to the official presentation of Intel’s Meteor Lake-PS platform by iBase, there was the first concrete information on the upcoming LGA 1851 socket and the Arrow Lake-PS CPU series based on it, according to a report by ComputerBase.
Meteor Lake-PS and Arrow Lake-PS: CPUs without chipset
A central point of the new platform is the lack of a dedicated chipset. Meteor Lake-PS are notebook CPUs of the Meteor Lake class (Core Ultra 100) with an integrated chipset on the package, which are “transplanted” into an LGA package. This solution enables more compact designs, but is also accompanied by limitations in the number of PCIe lanes compared to classic desktop mainboards with a dedicated chipset. iBase presented the first LGA 1851 mainboard with Meteor Lake-PS, the MI1002, at the trade fair.
Roadmap for the LGA 1851 socket
Intel is building on the continuity of its embedded roadmap with the LGA 1851 socket. After Alder Lake-PS (12th core generation) and Raptor Lake-PS (new core generation), Arrow Lake-PS will follow at the end of 2024 as “Core Ultra Series 2”. This CPU generation will also use the LGA 1851 socket and will also appear in the desktop segment as the “Intel Core Ultra 200 Series”.
LGA 1851 and LGA 1700: Identical dimensions, different compatibility
Although the LGA 1851 socket looks identical to the LGA 1700 socket (from 12th Core Gen Desktop) at first glance, the two are not compatible. The identical dimensions of 45 mm x 37.5 mm are deceptive: Intel has changed the arrangement of the contact surfaces in the package to prevent incorrect assembly.
In this context, it is of course interesting that we had already published all the information about the socket exclusively almost a year ago, including the pin-out. Now it’s more or less official:

Desktop roadmap for the LGA 1851 socket
The LGA 1851 socket will be introduced in the desktop segment in the second half of 2024 with the “Arrow Lake-S” series. The first concrete details on this could be presented at Computex 2024 at the beginning of June. However, the focus of the trade fair is likely to be on Intel’s “Lunar Lake” platform, which is designed as a response to Qualcomm’s Snapdragon X Elite. The LGA 1851 socket marks the next step in Intel’s embedded roadmap and brings new, compact and energy-efficient CPU options with Arrow Lake-PS. Desktop users can look forward to the powerful “Arrow Lake-S” series in the second half of 2024.
Additional details:
- Performance increases: Specific performance details on the new CPU series are not yet available.
- Pricing: The pricing of LGA 1851 motherboards and CPUs should be competitive compared to their predecessors.
- Availability: The first LGA 1851 motherboards with Meteor Lake-PS are available immediately, Arrow Lake-PS and Arrow Lake-S will follow at the end of 2024.
With the introduction of the LGA 1851 socket and the Arrow Lake-PS CPU series, Intel is further expanding its leading position in the embedded market. The new platforms offer an interesting mix of performance, compactness and energy efficiency and should convince both existing and new customers.
