Our Verdict on Each
A 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.
Read the full reviewA perfectly balanced 45W processor that delivers desktop-like responsiveness in portable form factors, bolstered by strong iGPU and AI capabilities.
Best for: The Core Ultra 9 285H is highly recommended for users seeking a premium, thin-and-light laptop capable of handling heavy workloads without sacrificing portability. If you are a content creator, software developer, or gamer who values battery life and a lightweight chassis, this processor strikes the perfect balance. Its 45W base power ensures it runs cooler than the HX series, making it ideal for laptops under 5 pounds. The inclusion of Arc 140T graphics means you can even do light gaming or video editing without a discrete GPU. However, if your primary use case is rendering complex 3D scenes or running sustained compiles for hours, you might be better served by a thicker HX-class laptop. Ensure the laptop utilizes LPDDR5X to maximize battery life, and consider pairing it with a mid-range discrete GPU if you plan on serious gaming. It is the ultimate choice for a do-it-all premium ultrabook.
