Intel Core i7-3517U vs Intel Core i7-3667U
A side-by-side comparison of specs, performance and value. The Intel Core i7-3517U is an ultra-low voltage mobile processor launched in June 2012 as part of the Ivy Bridge family. Designed primarily for the burgeoning Ultrabook market, it operates at a 17-watt TDP, striking a balance between performance and battery life. Built on Intel's 22nm process, it features 2 cores and 4 threads. The processor runs at a base clock of 1.9 GHz and can dynamically boost up to 3.0 GHz using Intel Turbo Boost Technology. It includes 4MB of L3 cache and supports dual-channel DDR3 memory. The integration of Intel HD Graphics 4000 provided a noticeable improvement in graphical capabilities over the previous generation's HD 3000, allowing for basic 1080p gaming and smooth hardware-accelerated video decoding. While its dual-core architecture limits its multi-threaded potential by modern standards, the 3517U was a highly capable chip in its era, powering countless thin-and-light laptops and ultrabooks.

Our Verdict on Each
A capable 2012 ultrabook chip, but its dual-core design is too slow for modern multitasking.
Best for: If you are considering a laptop with the Intel Core i7-3517U today, it should only be purchased in the used market at an extremely low price. It remains capable of very basic web browsing and document editing, but its 2-core design is a major bottleneck for modern multitasking. 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. For any primary computing needs, investing in a newer platform is strongly recommended for better efficiency, security, and performance.
