Intel leak details upcoming Core Ultra 400 Series desktop CPUs, including a 52-core model

A new report via VideoCardz, citing Intel's internal Nova Lake-S roadmaps as the source, has lifted the lid on specs and details for the company's upcoming next-gen Intel Core Ultra 400 Series desktop processors. According to the materials obtained, the new CPUs will be tile-based like Arrow Lake-S and will introduce lower-power E-cores called LPE-cores.

They'll also support the new LGA1954 socket but will retain the same cooler compatibility as the report, noting that the plan is for this socket to be forward-compatible with upcoming Intel CPU hardware, similar to how AMD's AM5 and AM4 platforms supported multiple generations of chips. The new Core Ultra 400 Series will also include dual-die processors, paving the way for higher core counts.

And with that, what makes this report interesting is that it offers what could become the entire lineup, from the new Core Ultra 3 to the new Core Ultra 9. This includes everything from a 6-core CPU to a 175W 52-core model, which may or may not be for the consumer market. That said, we'd love to see Intel release a Threadripper-style 52-core Core X CPU for enthusiasts.

Per the leak details, these new chips will sport Coyote Cove P-cores, Arctic Wolf E-cores, Intel NPU 6, and DDR5 memory support up to 8000 MT/s. In addition, Intel is set to include Wi-Fi 7 and CUDIMM and CSODIMM memory support, up to three PCIe 5.0 x4 lanes from the chipset, and multiple Thunderbolt 5 connections.

Here's the breakdown of Intel Core Ultra 400 Series 'Nova Lake-S' SKUs, which are reportedly in production for a planned Q4 2026 launch.
