CPU Comparison
Intel Core i7-3667U vs Intel Core i7-4500U
A side-by-side comparison of specs, performance and value. The Intel Core i7-3667U is an ultra-low voltage mobile processor launched in June 2012 as the premium tier of the Ivy Bridge ULV family. Designed for high-end ultrabooks, it operates at a 17-watt TDP. Built on Intel's 22nm process, it features 2 cores and 4 threads. The processor runs at a base clock of 2.0 GHz and can boost up to 3.2 GHz. It includes 4MB of L3 cache and supports dual-channel DDR3 memory. The integration of Intel HD Graphics 4000 provides a significant graphical uplift over previous generations, capable of handling 1080p video decoding and light gaming. While its dual-core design limits multi-threaded performance, the 3667U was one of the fastest mobile dual-core processors available in 2012, offering excellent single-core responsiveness for demanding ultrabook users.

Our Verdict on Each
A 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.
