Core i5-8279U Details

For users seeking a balance of performance and power efficiency in a mobile platform, the Intel Core i5-8279U offers a compelling option from Intel's Coffee Lake-U lineup. Launched in April 2019, this processor is now over four years old, placing it in the category of mature technology, though it remains relevant for mainstream computing tasks. Designed for mobile devices, the i5-8279U features a 4-core, 8-thread configuration, enabled by Intel Hyper-Threading, and operates at a base frequency of 3.7 GHz with a turbo boost up to 4.1 GHz. Built on a 14 nm process node and using the FC-BGA1528 package, it integrates 6 MB of L3 cache and supports up to 32 GB of dual-channel DDR3/DDR3L memory running at 2133 MT/s, with a maximum memory bandwidth of 25.6 GB/s.

The Core i5-8279U is equipped with Intel's Iris Pro Plus 655 integrated graphics, which features a base frequency of 350 MHz and can burst to 1.3 GHz, supporting up to three displays. While not designed for high-end gaming or intensive graphics workloads, this GPU provides capable performance for office applications, media playback, and light creative tasks. The processor supports a wide array of instruction sets, including AVX, AVX2, SSE4.1/4.2, and AES-NI, ensuring compatibility with modern software and enhanced performance in computational tasks.

In benchmark testing, the Core i5-8279U achieves an Overall Score of 5468, ranking it #502 among 2060 processors. Its Singlecore Score of 5700 places it at #420, while its Multicore Score of 5120 lands at #554. These results place the i5-8279U in the mid-tier of desktop and mobile processors, outperforming older models like the Core i5-9600 and Core i5-8600 but falling behind newer generation chips such as the Core i7-1065G7 and Ryzen 5 4600G. Its strongest performance category is single-threaded workloads, where it ranks notably high, indicating excellent responsiveness for everyday applications and productivity software.

The processor's 84 W TDP reflects its focus on performance within a power-constrained mobile environment, and its support for Intel vPro and hardware virtualization technologies makes it suitable for business and enterprise use cases. With a transistor count of 2.3 billion and a die area of 126 mm², the i5-8279U demonstrates a mature yet capable design. As of March 2026, while it is no longer at the forefront of performance, the Core i5-8279U remains a reliable choice for users who require a balance of performance, efficiency, and integrated graphics in a mobile system, particularly in business laptops and thin-and-light devices.
