Intel Core i3-7100U Details

The Intel Core i3-7100U, released in 2016, is a dual-core mobile processor built on the Kaby Lake microarchitecture using a 14 nm process. Despite its age, it remains relevant for basic computing tasks due to its integrated HD Graphics 620 GPU and low 15 W TDP, making it suitable for thin and light laptops. The processor features a base clock of 2.4 GHz with a maximum turbo frequency of 3.0 GHz, supported by 3 MiB of L3 cache and 0.5 MiB of L2 cache. It supports up to 32 GiB of DDR4-2133 or DDR3L-1600 memory across two channels, with a maximum memory bandwidth of 31.79 GiB/s.

In terms of performance, the Core i3-7100U scores 4652 in the overall benchmark, ranking #1148 out of 2060 processors. Its single-core performance is slightly stronger, with a score of 4735, placing it #1126 in the single-core category. The multicore score stands at 4528, ranking #1180. These results indicate that the processor performs comparably to older mainstream mobile CPUs, but it trails significantly behind modern high-end and even mid-tier offerings. The most notable performance gap appears in the multicore domain, where the processor is outpaced by nearly every modern CPU in the market.

The integrated HD Graphics 620 GPU operates at a base frequency of 300 MHz and can boost up to 1.0 GHz, supporting up to three displays and offering decent performance for light multimedia and office applications. The CPU includes a range of modern features such as AVX2, AES-NI, and Intel Speed Shift, which improve efficiency and responsiveness. It also supports ECC memory, although this is typically limited to server or workstation configurations. The processor is designed for low-power environments and can reduce its TDP to 7.5 W at 800 MHz, enhancing battery life during idle or low-load scenarios.

As of March 2026, the Intel Core i3-7100U is best suited for users seeking a lightweight, energy-efficient device for web browsing, document editing, and media playback. It is no longer competitive in demanding applications such as video editing or gaming. However, its low power consumption and reliable integrated graphics make it a practical choice for entry-level notebooks and business laptops where performance is secondary to portability and battery life. While it has been surpassed by generations of more powerful and efficient CPUs, it remains a viable option in budget-oriented or legacy systems.
