The Intel Core Ultra 7 270HX Plus is a refreshed iteration of the Arrow Lake-HX mobile processor family, scheduled for release in March 2026. Building upon the foundation of the 255HX, this 'Plus' variant offers slightly higher clock speeds while maintaining the same 20-core, 20-thread hybrid architecture. It features 8 'Lion Cove' P-Cores and 12 'Skymont' E-Cores, but boosts the maximum turbo frequency to 5.3 GHz. Manufactured on TSMC's 3nm process, the chip retains the 243 mm² die size and 17.8 billion transistor count. With a 55W base power and 160W turbo power, it targets the highest-end gaming laptops and mobile workstations. The package includes Arc Xe-LPG Graphics 64EU and a 13 TOPS NPU. This refresh aims to provide a moderate performance bump to stay competitive in the rapidly evolving mobile enthusiast market, offering an unlocked multiplier for extreme tuning.
Intel's Core Ultra 7 270HX Plus refines the Arrow Lake-HX formula with a higher 5.3 GHz turbo clock. Retaining the 8 P-Core and 12 E-Core design, it targets premium gaming laptops.
While the NPU remains at 13 TOPS, the unlocked multiplier and increased frequencies make it a compelling choice for enthusiasts needing maximum frame rates.

Architecture Overview
The Arrow Lake-HX Refresh architecture maintains the core tenets of the original design, prioritizing raw physical core count over Hyper-Threading. The 270HX Plus utilizes the same 'Lion Cove' P-Cores and 'Skymont' E-Cores, leveraging TSMC's 3nm node for optimal performance density. The architecture supports dual-channel DDR5 memory up to 6400 MT/s, delivering a memory bandwidth of 102.4 GB/s. A standout feature is the expansive PCIe support, offering 20 Gen 5 lanes and 4 Gen 4 lanes, facilitating multi-GPU setups and ultra-fast storage configurations. The integrated Arc Xe-LPG Graphics (64 EU) operates at dynamic frequencies up to 1900 MHz, providing capable display output and basic rendering capabilities. The NPU 3 delivers 13 TOPS, pushing the total platform AI capabilities to 33 TOPS when combined with the CPU and GPU, though the primary focus of this architecture remains raw compute power and discrete GPU synergy.

History
The Core Ultra 7 270HX Plus arrives in 2026 as a strategic refresh to Intel's Arrow Lake-HX lineup. Historically, Intel has utilized mid-cycle refreshes to maintain competitive parity against rival AMD's product stack. As the original Arrow Lake-HX began to age slightly in the fast-paced mobile market, the 270HX Plus was introduced to inject higher clock speeds and refined silicon maturity.
This processor represents Intel's commitment to the BGA 2114 socket, offering OEMs an easy upgrade path to market newer laptop models without requiring a full motherboard redesign. By bumping the turbo frequency to 5.3 GHz, Intel aimed to improve single-threaded performance and gaming frame rates.
The 'Plus' moniker signifies this incremental step, ensuring that Intel's enthusiast mobile segment remains highly competitive until the next major architectural overhaul arrives, extending the lifespan of the Arrow Lake platform.
Improvements over Previous Generation
- 100 MHz higher max turbo frequency
- Improved GPU dynamic frequency (up to 1900 MHz)
