Intel LGA 1851

The LGA-1851 socket represents a significant leap in technology for Intel’s chipset motherboards. LGA1851 will be the socket that Intel’s Arrow Lake launches on – so to use Intel’s 15th generation processors, you will need to upgrade to an LGA-1851 motherboard. Let’s dive into what this socket is all about, its features, and why it’s essential in the landscape of modern computing.

Introduction to LGA-1851 Socket

What exactly is the LGA-1851 socket? It’s a cutting-edge socket designed for Intel’s 800-series chipset motherboards, likely debuting with the Z890 series​​. The name ‘LGA-1851’ gives a hint to its novel design: it features 1,851 pins, which is 151 more than its predecessor, the LGA1700 socket​​.

When Do LGA-1851 Motherboards Come Out?

LGA-1851 motherboards will launch alongside the release of Intel’s Arrow Lake CPUs in late 2024.

Technical Specifications

Pin Layout and Compatibility

The LGA-1851 socket maintains the same physical dimensions as the LGA1700 socket, measuring 45×37.5 millimeters​​. This consistency in size is crucial because it ensures compatibility with cooling solutions designed for the LGA1700, offering users a degree of backward compatibility and ease of upgrade​​.

Designed for Future Processors

Intel’s LGA-1851 socket is tailored for the 15th generation Arrow Lake S CPU, marking it as a forward-thinking component in Intel’s lineup​​. It’s also intended for use with Meteor Lake, Arrow Lake-S, and Lunar Lake-S desktop processors, which are set to release in 2024​​.

Advancements in Performance

Enhanced Pin Count

The increased pin count to 1,851 plays a pivotal role in enhancing the socket’s performance. This 9% increase in pins compared to the LGA1700 socket allows for improved I/O interfaces, enabling the socket to close the performance gap with its AMD counterparts​​.

Consistent Pin Pitch

Despite the increase in the number of pins, the LGA-1851 maintains a consistent pin pitch with its predecessor. This design choice is critical for maintaining compatibility with existing cooling solutions and ensuring a smooth transition for users upgrading their systems​​.

Compatibility and Future-Proofing

Socket and Processor Size

The LGA-1851 socket and its compatible processors will maintain the same size as the LGA1700, a strategic decision by Intel to ensure a wide range of compatibility with existing hardware and cooling solutions​​. This compatibility is essential for users who wish to upgrade their systems without the need for a complete overhaul.

Supporting Next-Generation CPUs

Being tailored for Intel’s 15th gen Arrow Lake S CPU, the LGA-1851 socket is positioned at the forefront of technology, ready to support next-generation CPUs. This future-proofing is a key factor in its design, ensuring that users investing in this technology are prepared for upcoming advancements in computing power​​.


In conclusion, the LGA-1851 socket is a pivotal component in Intel’s chipset motherboard lineup. Its increased pin count, backward compatibility, and readiness for future processors make it a key player in the next generation of computing technology.
