Core i7-3687U Details

The Intel Core i7-3687U stands as a mid-range mobile processor from Intel's 3rd generation Core series, released during a period when the company was transitioning to more efficient architectures. While it is now considered an older device, having been launched several years ago, it still holds relevance for users seeking a balance between performance and power efficiency in lightweight laptops. As of March 2026, the processor remains part of the broader landscape of consumer-grade CPUs, though it is no longer competitive with modern high-end offerings.

Built on a 22 nm process and based on the Ivy Bridge microarchitecture, the Core i7-3687U features two cores and four threads, enabled by Intel's Hyper-Threading technology. It operates at a base frequency of 2.1 GHz, with a maximum turbo frequency of 3.3 GHz, allowing it to handle demanding workloads with reasonable responsiveness. The processor supports up to 32 GB of DDR3/L/RS 1333/1600 memory across two channels, delivering a maximum memory bandwidth of 25.6 GB/s. With a TDP of just 17 W, it is designed for low-power laptops and ultrabooks, where thermal constraints are a key consideration.

The integrated Intel HD Graphics 4000 GPU provides a modest level of graphics performance, featuring a base frequency of 350 MHz and a burst frequency of up to 1.2 GHz. It supports up to three displays and is capable of handling basic multimedia tasks, light gaming, and video playback, though it lacks the power needed for modern AAA titles. The processor also includes support for a wide range of technologies, including AES-NI, AVX2, SSE4.1, and SSE4.2, ensuring compatibility with both legacy and modern software. Virtualization features such as VT-x and VT-d are present, making it suitable for light virtualization tasks.

In benchmark testing, the Core i7-3687U achieves an overall score of 4647, ranking #1150 among 2060 processors. Its single-core performance scores 4777, placing it at #1083, while its multicore performance totals 4451, ranking #1319. These results indicate that the CPU excels in single-threaded applications but trails significantly in multi-threaded workloads. When compared to modern processors, it is outperformed by nearly all contemporary CPUs, including even entry-level models like the Core i3-7100U and Pentium Gold 4415Y, which share similar or higher scores despite being newer.

The Core i7-3687U is best suited for users who prioritize portability and battery life over raw performance. It remains viable for general office tasks, web browsing, and light content creation, but is not ideal for intensive applications such as video editing, 3D rendering, or gaming. While its age and limited scalability make it outdated by today's standards, it still offers adequate performance for users who do not require the latest technological advancements.
