CPU Comparison
Intel Core i7-3537U vs Intel Core i7-3667U
A side-by-side comparison of specs, performance and value. The Intel Core i7-3537U is an ultra-low voltage mobile processor launched in January 2013 as a minor refresh within the Ivy Bridge family. Designed for thin-and-light laptops and 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, offering a slight frequency bump over the older i7-3517U. It includes 4MB of L3 cache and supports dual-channel DDR3 memory. The integration of Intel HD Graphics 4000 provides capable multimedia performance for a chip of its era. While its dual-core architecture is a major bottleneck by modern standards, the 3537U was a reliable performer in 2013, bringing snappy single-core responsiveness to premium portable systems.

Our Verdict on Each
A capable 2013 ultrabook chip, but its dual-core design is too slow for modern multitasking.
Best for: When considering the Intel Core i7-3537U today, it is crucial to recognize its age and severe limitations. It should only be purchased in the used market at a significant discount. It remains capable of basic web browsing, document editing, and media consumption, but its 2-core, 4-thread design is a major bottleneck for modern multitasking and 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 on a very tight budget who only need to write papers. For any primary computing needs, investing in a newer platform is strongly recommended.
