CPU Comparison
Intel Core i7-3687U vs Intel Core i7-3689Y
A side-by-side comparison of specs, performance and value. The Intel Core i7-3687U is an ultra-low voltage mobile processor launched in January 2013 as a refresh within the Ivy Bridge ULV family. Designed for premium thin-and-light laptops, 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 2.1 GHz and can boost up to 3.3 GHz, making it one of the highest-clocked Ivy Bridge ULV chips. It includes 4MB of L3 cache and supports dual-channel DDR3 memory. The integration of Intel HD Graphics 4000 provides capable multimedia performance. While its dual-core architecture limits multi-threaded performance by modern standards, the 3687U was a top-tier performer in 2013, offering snappy single-core responsiveness for premium ultrabook users.

Our Verdict on Each
A top-tier 2013 ultrabook chip, but its dual-core design is too slow for modern multitasking.
Best for: When considering the Intel Core i7-3687U today, it is crucial to recognize its age and 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 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 on a very tight budget. For any primary computing needs, investing in a newer platform is strongly recommended for better efficiency, security, and overall performance.
Read the full reviewA pioneering 13W chip for 2013 tablets, but its dual-core design is far too slow for modern multitasking.
Best for: If you are considering a device with the Intel Core i7-3689Y today, it should only be purchased in the used market at an extremely low price for very specific legacy needs. Its 2-core, 4-thread design is a massive bottleneck for modern multitasking, and its 13W TDP, while low for 2013, is easily outclassed by modern 5W ARM processors. It is suitable for basic web browsing, document editing, and light media consumption, but it will struggle with any modern productivity workload. Avoid this processor if you need to run modern applications, do video editing, or play games. It is best suited as a cheap, secondary machine for light duties or for collectors of vintage mobile hardware.
