Intel's upcoming Alder Lake-S line-up of desktop processors is expected to make a debut in the very near future. To host these processors, we are about to see a major socket change in the form of the LGA 1700 CPU socket, which got pictured today.

According to the Bilibili forums, and reported by VideoCardz, we have one of the first pictures of Intel's LGA 1700 socket, codenamed 15R1, for upcoming Alder Lake-S processors. This new socket is taller than the previous LGA 1200 socket powering the current generation of Core processors codenamed Rocket Lake.

Intel has adjusted the height by adding an additional 2.5 mm, as the LGA 1700 socket has to make room for additional pins, resulting in a bigger design. It has markings noting "LGA-17XX/LGA-18XX", which alludes to this socket being able to accommodate processors with 1700 and 1800 pins. The upcoming Alder Lake-S generation is supposed to utilize 1700 pins, while the next-next generation of processors codenamed Raptor Lake will use 1800 pins. It looks likely that this socket will work for two generations of processors.

Below, you can find the table of specifications for the upcoming LGA 1700 socket, and some further details about the installation force that is listed.

Intel LGA 1700 Socket Details
IHS to MB Height (Z-Stack, validated range):6.529 – 7,532 mm
Thermal Solution Hole Pattern:78 x 78 mm
Socket Seating Plane Height:2.7 mm
Maximum Thermal Solution Center of Gravity Height from IHS:25.4 mm
Static Total Compressive Minimum:534N (120 lbf), Beginning of Life 356 N (80 lbf)
End of life maximum:1068 N (240 lbf)
Socket Loading:80-240 lbf
Dynamic Compressive Maximum:489.5 N (110 lbf)
Maximum Thermal Solution Mass:950 gram

As you can note, the height change from the CPU IHS to the cooler cold-plate has been changed, forcing cooler manufacturers to ship accommodating brackets for the new LGA 1700 socket. Mostly, manufacturers have been announcing that they will be providing new mounting brackets free of charge for customers who demand them.

As we await the launch of Alder Lake processors, it is important to remember that this change is one of the biggest changes that Intel has made to its platform in recent years. Primarily because the company is now using a hybrid CPU core setup of big and little cores, where the system operates similar to Arm's big.LITTLE principle. The Alder Lake generation will feature a maximum of 8 "Golden Cove" big cores with Hyper-threading and 8 small "Gracemont" cores without Hyper-threading enabled. The generation that replaces Alder Lake, called Raptor Lake, will be based on 8 big "Raptor Cove" cores, and as many as 16 "Gracemont" energy-efficient cores.

    Wooo new motherboard, ram (depending on the motherboard model), and a new cooler for intels new cpu's. Eh I guess they have been using the same cooler mounting layout since LGA 1156.

    My next upgrade. It has been a long while since I did 3 i9-9900K upgrades for my sons and me. This has everything I have been waiting for, new PCI-E upgrade, new memory upgrade, new WiFi upgrade, and new Thunderbolt upgrade. I don't care that much about the extra cores unless they actually make some sort of difference in a regular user like me. I am already running Win 11 and the Alder Lake scheduler will (hopefully) take advantage of the OS. Not going to be cheap and this will be my most expensive CPU ever. STILL waiting for EVGA to stock the 3080 Ti and since NVidia is going to release a new family next year, might be reasonable to just say no.

    Long while??? It can't be more than about three years?!?

    Me on 3600 for quite sometime already...haha, itching for an upgrade....lets see how this compares with AMD. If its faster, I will get it.

    "It looks likely that this socket will work for two generations of processors."

    This is typical of Intel. And hopefully, they won't say that H6xx series will not be supported with next gen CPUs, even though the pin count is the same.

    If you call 3 years a "long while", I wonder what adjective you use for my upgrade cycle: Sandy Bridge in 2011 to Ryzen 3000 in 2019?

    Haha, I think of my 3600 as brand-new! I'll probably end up with a 6900X in there in two years and ride it until 2027.

    Hey, I'm just impressed that they plan for it to work with TWO generations at this point. That's one of the many reasons I won't be going back to Intel.
