Intel confirms switch to LGA 1700 socket for Alder Lake CPUs

Forward-looking: It seems there’s nothing Intel loves more than launching new sockets. With LGA 1200 only recently released alongside the 10th-gen Comet Lake chips, more evidence has emerged that the 12th-gen Alder Lake processors will switch to a new, LGA 1700 socket.

Soon after the Core i9-10900K CPU was revealed back in April, we got confirmation that the new 400-series motherboards would also support the 11th-gen Rocket Lake CPUs, which are due to arrive next year.

In May, a Taiwanese company that provides voltage regulation test tools to Intel in the Asia-Pacific market suggested that the LGA 1200 socket will only be used for two generations of processors. It listed several future Intel CPUs, including the codename for Alder Lake-S with a description revealing it supports the LGA 1700 socket.

Now, a leaked Intel document from twitter user @momomo_us seemingly confirms it: those who want an Alder Lake CPU will need a new motherboard with an LGA 1700 socket. Alder Lake-S refers to the desktop chips, but it’s unclear what Alder Lake-P might be.

While the LGA 1200 socket brought few changes over its LGA 1150 predecessor, LGA 1700, which is expected to launch in early 2022, will reportedly be a lot different to what's come before. In addition to the 500 extra pins, we’ve heard that the socket will be a rectangular shape (45mm × 37.5mm) rather than the usual square. We’ve also heard that Alder Lake will use a BIG.little design similar to Arm's, combining eight high-powered cores with eight energy-efficient ones. It will also support DDR5 RAM and PCIe 4.0—later versions might support PCIe 5.0.

Alder Lake is expected to use the 10nm++ process node and will likely feature Intel’s Xe integrated graphics, which we recently saw running Battlefield V at 30fps on a laptop without a dedicated graphics card.

LGA775 wants to speak to you.
Well...

"LGA775 v1" supported single core Pentium 4 CPU's
"LGA775 v2" supported dual core Pentium 4 CPU's
"LGA775 v3" supported Core 2 CPU's with 266 MHz FSB or less
"LGA775 v4" supported Core 2 CPU's with 333 FSB and more

Yeah, socket is "same" but who cares?

LGA1151 also "supports" following:

Skylake, Kaby Lake, Coffee Lake

Too bad, compatibility was broken between Kaby Lake and Coffee Lake.

Again, socket is "same" but nobody cares.

Does 1700 pins indicate a big jump in performance?
It has 41% more pins than i9-10900K has. So performance is expected to be up same amount.

Just kidding. Alder Lake is supposed to have 8+8 configuration and that explains high pin count. Software support is likely be abysmal at start, because 8 cores are "strong" and 8 "weak". And current Windows software usually handle all cores equal.

The bulk of a CPU’s socket pins are split roughly equally between connections for the system memory and PCI Express lanes, and power supply lines. So the jump from 1151/1200 to 1700 suggests that future platforms will support an increase PCIe lanes and power consumption, the latter being due to more cores and cache. This is why AMD designed AM4 to have 1331 pins, even though the first Ryzen chips were at most 8 cores.

" The socket had an unusually long life span, lasting 7 years until the last processors supporting it ceased production in 2011. "

That's 9 years ago :)
I consider socket life span end when true successor is released. Because using that "production stopped" logic, for example Intel 486 had lifespan of 18 years! Intel made them for spaceships long time.

LGA775v4 supported everything the previous versions had to offer. Can't say that for any of the new Intel sockets now.
