Our Verdict on Each
M3 Max pairs exceptional multi-core performance with massive memory capacity and an efficient 3nm design, making it a top choice for pro creators and developers who need workstation-level capability in a MacBook Pro.
Best for: Used or open-box MacBook Pro with M3 Max for creators and developers needing high RAM capacity and multi-core performance at a lower price than M4 Max.
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.
