Mobile
The Intel Core Ultra 5 235HX is a 14-core unlocked mobile processor delivering high clock speeds and substantial PCIe Gen 5 connectivity for flagship gaming laptops.
The 235HX features the same 6 P-Core and 8 E-Core configuration as its higher-tier sibling but drops the base clock to 2.9 GHz. It maintains the 160W turbo power limit and fully unlocked multiplier for enthusiast tuning.
Specifications
Performance
Slightly lower base clock results in a minor drop in sustained multi-threaded tasks.
More than capable of handling local development environments.
Delivers nearly identical gaming FPS to the 245HX due to the same 5.1 GHz boost clock.
Shares the same poor battery life characteristics as other HX-class chips.
- •5.1 GHz boost clock ensures high frame rates
- •Unlocked multiplier can optimize performance per specific game
- •Best paired with an RTX 4070 or 4080 mobile GPU
- •13 TOPS NPU is insufficient for modern AI PC standards
- •Requires a discrete GPU for meaningful AI workloads

History
The Core Ultra 5 235HX was introduced as the price-performance champion of Intel's initial Arrow Lake-HX lineup. By taking the exact same silicon as the 245HX and slightly reducing the base clock, Intel created a chip that appealed to OEMs looking to build more affordable overclockable gaming laptops. <br>This strategy allowed gamers to access the new Lion Cove and Skymont architectures, along with the unlocked multiplier, without paying the premium tax associated with the top-tier SKU.
It solidified the HX line as the go-to for mobile enthusiasts who prioritize frame rates over battery life.
Improvements over Previous Generation
- New Lion Cove and Skymont core architectures
- 3nm process node
- Unlocked multiplier (vs locked on 14500HX)
- Introduction of PCIe Gen 5
