Intel Core i3-8100 vs Intel Core i5-9600K

Last updated:
The Intel Core i3-8100 is an eighth-generation desktop processor with the "Coffee Lake S" architecture, aimed at the mainstream market.

It was designed for users who need a solid foundation for everyday computing tasks and light productivity. Manufactured using a 14 nm process, this processor features 4 cores and 4 threads. Its single-core performance is sufficient for typical applications, while multi-core performance supports basic multitasking.

The maximum memory bandwidth is 38 GB/s, and it is compatible with PCIe Version 3.0. With 6 MB of Level 3 Cache and integrated Intel UHD Graphics 630, it offers functional features. It is less suitable for demanding games or computationally intensive applications. However, its moderate power consumption makes it an energy-efficient choice for office and home entertainment systems.

The Intel Core i5-9600K is a ninth-generation desktop processor based on the "Coffee Lake S Refresh" architecture.

It appeals to users with higher performance demands, especially in gaming and for more demanding productivity tasks. The "K" in the name indicates an unlocked multiplier for overclocking, which can enable additional performance. Also manufactured using a 14 nm process, this processor offers 6 cores and 6 threads.

It delivers significantly higher single-core performance and noticeably improved multi-core performance compared to the Intel Core i3-8100. The maximum memory bandwidth is 43 GB/s, and it also supports PCIe Version 3.0. With 9 MB of Level 3 Cache and integrated Intel UHD Graphics 630, it is well-equipped.

Its high clock speeds and overclocking capability make it an excellent choice for gaming. However, its higher performance requires a more robust cooling solution.
