Our Verdict on Each
A highly capable 14-core mobile CPU offering excellent value and overclocking potential, though the basic iGPU is a drawback.
Best for: Mid-to-high-end gaming laptops with RTX 4060 or 4070.
Read the full reviewA strong performer in the thin-performance category, offering excellent multi-core capabilities and strong integrated graphics.
Best for: If you are a content creator, programmer, or moderate gamer seeking a laptop that balances power and portability, the Core Ultra 5 135H is a smart investment. Its 14-core design and 96EU integrated graphics handle video editing and 1080p gaming admirably. Ensure the laptop has adequate cooling, as the processor can draw up to 115W during sustained loads. Avoid this chip if you strictly need all-day battery life in a thin chassis; the U-series would be more appropriate. For users wanting to future-proof their purchase for AI-enhanced applications without paying for a higher-tier Core Ultra 7, the 135H strikes an excellent price-to-performance ratio in the premium mobile space.
