The leak comes from the ever-inquisitive InstLatX64, who dug up a Chipzilla document apparently outlining future silicon for both desktops and mobile devices. On paper, there’s a fair bit: Nova Lake in S and U variants, the rumoured P-core-only Bartlett Lake-S family for LGA1700, and some grist for the Time Coordinated Computing mill.
As is typical for Chipzilla, the whole thing has a sizeable disclaimer saying it’s not a Plan Of Record. That means it’s a nice set of ideas someone in a lab is hoping to build, but don’t hold your breath for delivery.
Still, Panther Lake is shaping up to be more than vapourware. Chipzilla reckons these mobile chips will hit High Volume Manufacturing later this year and land on shelves in early 2026. The company even wheeled out a few Reference Validation Platforms at Computex. Official die shots show five tiles, though only the Compute, GPU, and Platform Controller bits seem set to be active.
The monolithic Bartlett Lake chips are in the mix. While the hybrid siblings showed their faces at CES, this version is being eyed for a Q3 2025 release, possibly between July and September. It’s supposed to bring 12 P-cores and 24 threads in a format that slots into current 600- and 700-series LGA1700 motherboards without a fuss.
Then there’s Nova Lake, Chipzilla’s next big architecture swing for 2026, following Arrow Lake. The S variant might boast up to 52 hybrid cores, but will likely require a jump to the LGA1954 socket. Anyone hoping to cling to their old kit might be out of luck.
Some earlier Linux kernel patch whisperings hinted at a high-performance mobile Nova Lake-H, but the slide suggests Chipzilla is also playing with U-class low-power chips. Whether they actually share the same architecture as the desktop versions or just wear the same badge is still anyone’s guess.
