Our Verdict on Each
A breakthrough mobile chip that brought console-like integrated graphics to thin-and-light laptops, though limited to 4 cores.
Best for: Buying a mid-range ultrabook for everyday use and light gaming.
Read the full reviewA top-tier 2012 ultrabook chip, but its dual-core design is too slow for modern multitasking.
Best for: When considering the Intel Core i7-3667U today, it should only be purchased in the used market at a rock-bottom price. It remains capable of basic web browsing, document editing, and media consumption, but its 2-core design is a major bottleneck for modern multitasking and heavy web applications. Avoid purchasing a laptop with this CPU if you need to do any modern productivity work, video editing, or gaming. It is best suited for budget-conscious buyers who need a cheap, secondary machine for light web browsing or for students who need a basic word processor on the go. For any primary computing needs, investing in a newer platform is strongly recommended for better efficiency, security, and overall performance.
