New Details Emerge for Intel’s Future Meteor Lake and Arrow Lake CPU Generations: New LGA-2551 Socket Coming Next Year

Intel‘s latest generation of desktop processors is right around the corner. Raptor Lake, aka 13th Gen Core series is expected to launch in the fourth quarter of this year with incremental improvements over the current-gen Alder Lake CPUs. The biggest upgrade comes in the form of maximum core count, jumping from 16 cores to 24 cores at the top-end.

Despite that, we already have rumors for generations succeeding this year’s launch and today’s report reveals some interesting new things. According to Moore’s Law Is Dead, there are some big changes planned for Meteor Lake and Arrow Lake. While on the GPU side of things, it seems like Intel is not experiencing a smooth sail.

Meteor Lake and LGA 2551 socket

For starters, Meteor Lake, aka 14th Gen Core series, is supposed to launch in Q4 2023 and will compete with AMD‘s Zen5 architecture. The maximum core count will remain same at 24 cores for the flagship offerings. However, the titular leaker reports on one major change that contradicts what we’ve previously known about Intel’s next lineup of processors.

MILD reports that Intel will introduce a new socket with Meteor Lake. This goes against current leaks that suggested Intel would stick with LGA 1700 for at least three years. For those who don’t remember, LGA 1700 was launched alongside Alder Lake, around a year ago. The upcoming Raptor Lake family will still use the LGA 1700 platform, but apparently Meteor Lake will bring LGA 2551 to the market.

That means LGA 1700 will become outdated in just two years after Meteor Lake launches in 2023. As for the specifics, LGA 2551 socket is only slighly larger than LGA 1700 in physical size, though it does include around 50% more pins as suggested by its name. MILD says the socket measures at 38 x 46 mm. For context, the current LGA 1700 socket is 37.5 mm x 45 mm, so you can see how close they are.

Attached below is allegedly a real picture of the LGA 2551 socket, provided by MILD:

Moreover, MILD also confirms some other rumors that were reported on by various leakers these past few weeks like the 12-21% uplift in Instructions Per Clock (IPC), and “Crestmont” being the new Small Core (E-Core) architecture for Meteor Lake. On top of that, Meteor Lake will utilize a new node design incorporating three different nodes into one CPU for maximum potential.

All that being said, while most leakers have said Meteor Lake would launch in 2024, MILD says Intel is planning a Q4 2023 release, which falls right in-line with the release pattern Intel has been and will follow for its desktop CPUs.

Arrow Lake

If it seemed like Meteor Lake news was hear sooner than expected, you’ll be blown away by how much we know about Lunar Lake, the follow-up to next year’s 14th Gen Core series. MILD reports that Intel might debut Lion Cove P-Cores and Skymont E-Cores with Arrow Lake, aka 15th Gen Core series. Before, it was expected that Lion Cove and Skymont will launch with Lunar Lake, successor to Arrow Lake.

Interestingly enough, even four generations in, MILD does not expect Intel to bump up the P-Core count on its desktop processors. Though, there will be a massive increase in E-Cores with the maximum number jumping to 32-cores this generation. That constitutes a 2x increase over Raptor Lake. All in all, that means a total of 40 cores (8 P-Cores and 32 E-Cores) at the top-end for Arrow Lake. 

Lastly, MILD mentions that LGA 2551 socket will be compatible with Arrow Lake, which means the platform will at least live for two years before being replaced by its subsequent follow-up. Arrow Lake desktop processors are rumored to launch in the second half of 2024, once again, most likely in the last quarter of the year. Given their release schedule, these CPUs will be going up against Zen6 and whatever AMD has to offer at the time.

You can check out MILD’s full video breaking down these leaks here. Keep in mind MILD is sort of a divide in the community as a source, but even regardless of that take any rumor, including this one, with a pinch of salt. These products are years away at this point and anything can change between now and then. But if you like to take part in the future ahead of time, these leaks are plenty to keep us well-fed. 

Intel themselves released an official roadmap for processors to come that you can check out here.
