History
Arrow Lake-H represents Intel's second generation of tile-based mobile architecture, following the Meteor Lake foundation. The 235H introduces the Skymont E-core architecture to mobile platforms for the first time, paired with Lion Cove P-cores that bring significant IPC improvements over the previous Raptor Cove design.</br></br>What makes the 235H particularly interesting is its inclusion of Low-Power E-cores (LP-E), a concept carried over from Meteor Lake, designed to handle background tasks at extremely low power envelopes.
This tri-cluster approach allows Windows 11's Thread Director to dynamically allocate workloads based on performance and efficiency requirements.</br></br>The chip also features a substantially upgraded integrated GPU with Arc Graphics 140T, a major leap over the desktop Arrow Lake-S variants that still use the older Xe-LPG architecture. Intel positioned the 235H to compete in the premium thin-and-light segment where AMD's Ryzen AI 300 series has been gaining ground, offering a compelling mix of CPU performance, integrated graphics capability, and NPU-accelerated AI workloads.

Interesting Facts
The 235H is one of the few Arrow Lake processors to use LP-E-cores, a feature inherited from Meteor Lake but absent on desktop Arrow Lake-S.
Its Arc Graphics 140T iGPU has nearly nine times the TOPS rating (74) of the desktop Arrow Lake-S Xe-LPG 24EU graphics (6 TOPS).
The compute tile is manufactured on TSMC's N3B process, making it one of the first Intel-branded chips to use a sub-5nm node.
With 14 cores but no Hyper-Threading, the 235H has the same thread count as a 7-core CPU with HT enabled.
The chip uses four different TSMC process nodes across its tiles: N3B, N5, and N6 (twice).
LPDDR5X-8400 support provides 67.2 GB/s memory bandwidth, over 50% more than DDR5-6400 at 51.2 GB/s.
The 235H's NPU 3 is the same unit used across all Arrow Lake mobile and desktop processors.
Intel's Thread Director was specifically updated for Arrow Lake-H to manage the tri-cluster topology.
The cTDP range of 28W to 45W with a 115W PL2 gives OEMs unusually wide tuning latitude.
The 235H launched with the A1 stepping, suggesting early production maturity for the mobile variant.
