CPU Comparison

Intel Core i7-3517U vs Intel Core i7-3689Y

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.

A 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.
