The new LGA-1851 socket is the latest replacement for the LGA-1700. In terms of size, it’s identical to the LGA-1700, retaining dimensions of 45 x 35.7 mm, but it features more pins than its predecessor: 1851 compared to 1700, an increase of 151.
In summary, the new Intel® Core™ Ultra processors use the LGA-1851 socket, which, while sharing the same physical size and dimensions, is not compatible with older sockets like the LGA-1700. However, when it comes to cooling solutions, those designed for the LGA-1700 remain compatible with the LGA-1851, meaning existing thermal solutions created for the LGA-1700 can still be used without any modification.
With advanced support for the PCIe 5.0 standard for ultra-fast connections and compatibility with DDR5 memory, these processors deliver exceptional responsiveness for professionals and passionate gamers.
The socket supports Intel 14th generation Core processors, Intel Core Ultra 200 processors, and a maximum of up to 24 cores. It also supports DDR5 RAM (up to 6400 MHz) and DDR4 RAM (up to 3200 MHz).
So, if you’re looking for the perfect motherboard for your new Intel processor, make sure to check out those with the LGA-1851 socket!
