Core i3-8109U Details

Ranked #779 of 2060 in overall performance, the Intel Core i3-8109U sits in the mid-tier of consumer processors as of early 2026. While it's no longer a flagship chip, its performance remains relevant for basic productivity tasks and light multitasking. Launched in April 2018 as part of Intel’s Kaby Lake-U Refresh lineup, the i3-8109U is built on a 14 nm process and features a Coffee Lake U architecture with two cores and four threads thanks to Intel Hyper-Threading. Its base frequency of 3.0 GHz can boost up to 3.6 GHz, offering responsive single-threaded performance in everyday workloads.

The processor integrates the Iris Plus Graphics 655 GPU, which operates at up to 1.05 GHz and supports up to three displays. With 4 MB of L3 cache and 0.5 MB of L2 cache, the i3-8109U benefits from a balanced cache hierarchy that improves data access speed. It supports DDR4-2400 and LPDDR3-2133 memory, with a maximum of 32 GB and dual-channel bandwidth of 35.76 GB/s. The TDP of 28 W, down to 20 W in efficiency mode, makes it suitable for thin and light laptops where power consumption and thermal management are critical.

In benchmark testing, the Core i3-8109U earns a Singlecore Score of 5,469, placing it at #577 in the single-core rankings—outperforming many older and mid-range CPUs like the Core i5-7260U but falling short of modern high-performance processors. Its Multicore Score of 4,582 ranks it #1,113, indicating that while it can handle basic multi-threaded applications, it’s significantly outpaced by today’s mainstream and high-end CPUs. The overall score of 5,114 positions it well within the mainstream mobile segment, with competitive performance against processors like the Core i5-6287U and the Core i7-7660U.

The i3-8109U supports a wide range of Intel technologies, including Intel Speed Shift, Turbo Boost 2.0, Intel VT-x, and AES-NI, which enhance system responsiveness, virtualization, and encryption performance. It also includes support for AVX and AVX2 instruction sets, allowing for improved performance in media encoding and scientific computing. However, it lacks AVX-512 and does not support ECC memory, which limits its appeal in professional or server environments.

As of March 2026, the Core i3-8109U remains a viable option for users who prioritize battery life and portability over raw performance. It's well-suited for web browsing, office applications, and casual multimedia use in ultrabooks and budget laptops. While it may not compete with today’s high-end mobile processors, its longevity and efficiency make it a reliable choice for entry-level computing needs.
