New Intel LGA 1954 Socket Keeps Dimensions, Cooling Compatibility with Predecessors

Users considering Intel's future top-tier Nova Lake processors should prepare to buy a new motherboard, but not a new cooler. According to shipping documentation uncovered in NBD service logs, the Nova Lake-S lineup will debut with the LGA 1954 socket. The crucial news is that the socket's physical dimensions remain unchanged: 45x37.5mm. This matches the size of current LGA 1700 (Alder Lake, Raptor Lake) and upcoming LGA 1851 (Arrow Lake) sockets exactly.

The Nova Lake-S series will be Intel's first mainstream offering to break the 50-core barrier. The flagship chip, sources suggest, will feature a hybrid layout: 16 high-performance cores, 32 efficient cores, and 4 ultra-low-power (LPE) cores, totaling 52 cores. This more than doubles the core count of the current flagship Arrow Lake-S (Core Ultra 9 285K).

Manufacturing will utilize Intel's cutting-edge 14A node for key components and TSMC's 2nm process for supporting chiplets. The readiness of Intel's 18A-PT process for complex 3D packaging (3DIC) paves the way for Nova Lake variants with increased cache capacity, potentially providing a serious competitive edge against popular rival solutions.

The processors are expected to carry the Core Ultra 400S branding. Rumors indicate the Core Ultra 300 designation is reserved for mobile Panther Lake chips slated for late 2025. Desktop Intel Nova Lake-S processors are anticipated to arrive next year. So while users will need to budget for a new motherboard, their existing coolers should very likely remain compatible, as the report concludes.
