Intel's next-gen LGA-1851 socket has finally surfaced, and will support both Meteor Lake-PS & Arrow Lake-S "Core Ultra 200" CPUs.
Intel's LGA-1851 Shows High Resemblance With Its Predecessor, With Changes Made To The Mounting Mechanism: Supports Meteor Lake-PS "Core Ultra 100" & Arrow Lake-S "Core Ultra 200" CPUs
The LGA-1851 platform has set high hopes for consumers looking to switch to new standards, as the socket type will house Intel's Arrow Lake-S CPUs.
Still, interestingly, Intel has disclosed that the LGA-1851 will debut with the Meteor Lake-PS series, which is a lineup intended for the embedded segment, as discussed in a previous post. For a quick recap, the Meteor Lake-PS SKUs are made for emerging AI workloads in edge environments, which are getting a boost in performance due to the onboard Arc iGPU and the dedicated NPU engine.
Initial images of the LGA-1851 socket type, which was found in the MI1002 motherboard designed for the Meteor Lake-PS series, show that the socket is identical to the LGA 1700, mainly in terms of the overall dimensions, which are 45mm x 37.5mm. However, Intel has included more contact surfaces and attached dedicated shifting locking lugs to prevent older CPUs from mounting into the newer platform.
To quickly summarize the details, the rumors indicate the following features for Intel's LGA 1851 socket and Arrow Lake family:
- LGA 1851 Socket Longevity Planned Uptill 2026
- DDR5 Only Compatibility, No DDR4 Support
- Kicks off With 800-Series Motherboards
- Support For Up To DDR5-6400 Memory (Native JEDEC)
- Increased PCIe Gen 5.0 Lanes Through CPU & PCH
- Arrow Lake-S First Desktop Family Supported
- Arrow Lake-S CPUs feature 3 MB L2 Cache Per P-Core
- Arrow Lake-S CPUs feature refreshed Alchemist iGPUs
- Arrow Lake-S CPUs feature integrated LLC "Adamantine" for GPU Tile
- Arrow Lake-S CPUs feature 8+16, 8+0, 6+8 CPU SKUs
- Launching In 2H 2024
While the debut of LGA-1851 in the Meteor Lake-PS series is engaging, the more intriguing element is how the embedded markets are evolving, mainly because just recently, AMD announced their own Versal Gen 2 Adaptive chips, specifically designed to capture the growing interest the embedded AI.
With the debut of Intel's new Meteor Lake-PS & Arrow Lake-S Desktop CPUs, things will indeed get more competitive, and it will be interesting to see which architecture surpasses to be the superior one,
