Specifications, part numbers, and configurations for seven upcoming Intel Nova Lake-S desktop processors emerged in an October 2026 leak from LC Tech Leaks, led by the Core Ultra 9 4970K BFC.
- Seven total SKUs using a four-digit Core Ultra naming scheme
- Flagship Core Ultra 9 4970K BFC with 28 cores and 125W base power rating
- Additional lineup models include Core Ultra 9 4950K, Core Ultra 9 4900 BFC, Core Ultra 7 4870K BFC, Core Ultra 7 4850K, and Core Ultra 5 SKUs
- Processors require new LGA 1954 socket and 900-series chipsets
Core and Cache Layouts
The leaked flagship configuration combines eight performance cores, sixteen efficient cores, and four low-power efficient cores. This 28-core setup also integrates 32 graphics execution units alongside a big last-level cache.
Platform Requirements
Upgrading to the new processors demands a hardware shift. The components utilize the LGA 1954 socket architecture and require matching 900-series motherboards for installation.
Competitive Architecture Strategy
The inclusion of the BFC suffix and the big last-level cache hardware indicates Intel's structural approach to competing directly against AMD processors utilizing 3D V-Cache technology.
