Subsequent-Gen Intel Arrow Lake-S CPU Pinout & LGA 1851 Socket Detailed, New Mounting Required?

Full particulars concerning the Intel LGA 1851 socket which shall be supporting the next-gen Arrow Lake-S Desktop CPUs have been revealed by Igor’s Lab.

Intel LGA 1851 Socket Detailed: Designed For Subsequent-Gen Arrow Lake-S CPUs & Past

We first got here to know in regards to the Intel LGA 1851 “V1” socket by official paperwork posted by tech outlet, Benchlife. Now, we now have much more information obtainable on the next-gen socket due to Igor’s Lab. However beginning off with the fundamentals, the Intel LGA 1851 socket will largely be much like the prevailing LGA 1700 socket with some minor adjustments. The largest change would be the bump within the variety of contact pads which can go up from 1700 to 1851, a rise of 151 contact pins (+9% enhance). Along with that, the socket itself will measure the identical at 37.5mm x 45mm.


Along with that, the Z-height which is the gap from the highest of the motherboard to the highest of the CPU IHS will stay nearly the identical with just a few minor peak variations which is one thing that may simply be sorted out through the use of washers although it’s not concluded if that would be the case as correct contact between the IHS and the CPU cooler is one thing that was a significant level of concern when Intel launched its Alder Lake CPUs. The brand new processors would require extra stress from the coolers for optimum performance (923N vs 489.5N).

Igor explains that Intel has already despatched out the required paperwork that listing the adjustments we’ll see with Arrow Lake-S Desktop CPUs and the LGA 1851 socketed platforms to producers reminiscent of CPU coolers and AIO makers. This offers OEMs and producers loads of time to work on new merchandise and supply added help for current merchandise reminiscent of mounting kits (if wanted).

The explanation why Intel Arrow Lake-S requires a brand new platform and socket is defined as a way to meet up with AMD’s I/O capabilities. Whereas Intel’s 600 and 700-series platforms supply a big array of I/O performance, they nonetheless lack inside the SSD division. AMD’s AM5 platform is absolutely compliant with Gen 5 SSDs with CPU lanes reserved particularly for the newest storage gadgets. In the meantime, Intel companions have to separate Gen 5 lanes from PCIe x16 graphics in the event that they wish to supply Gen 5 help on the present motherboards. That is one thing that Intel desires to alter within the upcoming era of 800-series motherboards.

It’s acknowledged that Intel’s Arrow Lake-S Desktop CPUs will supply devoted Gen 5 x4 lanes for SSD and that’s along with the usual Gen 4 x4 lanes. The Arrow Lake-S Desktop CPU lineup is deliberate to launch in late 2024 and shall be supported by the LGA 1851 socketed motherboards inside the 800-series household. The corporate has an Innovation occasion deliberate for nineteenth September so we will count on extra particulars then.
