Leak Points to Intel Nova Lake-S With NPU6 Up to 74 TOPS and Slimmer Xe3-LPG iGPU

The unconfirmed specs suggest a desktop platform shift aimed at meeting Windows AI PC goals.

Overview

  • The claims were posted by leaker @jaykihn0 on X and reported by BenchLife and IT Home, describing Intel’s next desktop line targeted for 2026–2027, with no official confirmation from Intel.
  • The NPU6 is said to deliver up to 74 TOPS, a sizable jump from Arrow Lake-S at about 13 TOPS and from Lunar Lake and Panther Lake at roughly 48 and 50 TOPS, which outlets say could satisfy Windows 11 AI+/Copilot+ PC thresholds.
  • Integrated graphics reportedly move to Xe3-LPG, with some configurations limited to 2 Xe cores compared with Arrow Lake-S’s 4Xe, leaving real-world graphics performance to be determined.
  • Platform details point to 900-series motherboards and a new LGA1954 socket, with current LGA1851 coolers purported to remain compatible according to the leak.
  • A separate report the same day adds that unlocked Core Ultra 400K models are rumored to feature a 144MB big last-level cache, a claim that also remains unverified.
