Our Verdict on Each
An exceptionally fast mobile CPU that bridges the gap between desktop and laptop performance with high base clocks and massive core counts.
Best for: High-end desktop replacement laptop
Read the full reviewA true desktop replacement CPU delivering elite multi-core performance and overclocking headroom, provided the laptop can cool it.
Best for: The Core Ultra 9 285HX is highly recommended for users in the market for a top-tier gaming laptop or mobile workstation who need extreme multi-core performance without stepping up to a desktop. If your workflow involves software development, 3D modeling, or streaming while gaming, the 24 cores will handle the load effortlessly. However, prospective buyers must be aware of the thermal requirements; this chip demands a laptop with exceptional cooling to maintain its 160W turbo power. It is not suitable for students or professionals needing long battery life, as the 55W base power ensures it will deplete batteries quickly when unplugged. Ensure the laptop pairs this CPU with an RTX 4080 or 4090 class GPU to avoid a performance bottleneck. If you value overclocking and raw compute over portability, the 285HX is an excellent, future-proof investment.
