Intel Core Ultra 7 255H
Arrow Lake-H's upper-mid 16-core chip pairs 6 Lion Cove P-cores and 10 Skymont/Crestmont E-cores with a 24MB cache and Arc 140T graphics, aimed at demanding laptops that need both CPU muscle and light gaming performance.
Pros
- 16 cores (6 P-cores, 8 E-cores, 2 low-power E-cores) give strong multi-threaded throughput
- Lion Cove P-cores boost up to 5.1GHz for fast single-core response
- Arc 140T iGPU (8 Xe cores, up to 2.25GHz) runs modern games at 1080p on low-to-medium settings
- Supports fast LPDDR5X-8400 or DDR5-6400 memory, up to 128GB
- 24MB of L3 cache helps with multitasking and content-creation workloads
Cons
- No Hyper-Threading, so thread count matches core count instead of doubling
- 13 TOPS NPU misses the 40 TOPS Copilot+ PC certification threshold
- TDP can reach 115W under sustained turbo, requiring larger cooling
