About Intel Core i3-8350K

The Intel I3-8350K, also known as the Core i3-8350K or simply the i3-8350K, is a quad-core, non-hyperthreaded CPU from Intel’s Coffee Lake lineup that punches above its weight for budget builds. With a solid base clock of 4.00 GHz and no turbo boost, it delivers consistent single-threaded performance ideal for gaming and everyday tasks. In real-world usage, the Intel I3 8350K handles 1080p gaming smoothly with modern titles when paired with a decent GPU, though it may struggle in heavily multithreaded applications. Thanks to its 14 nm process and 91W TDP, it runs hot under load but remains manageable with proper cooling. The locked multiplier (despite the 'K' suffix) is a letdown for overclockers, but the high base clock compensates somewhat. Benchmark results show it scoring around 824 in Cinebench R23 single-core and 1,506 in Geekbench single-core, proving its strength in day-to-day responsiveness. While not built for heavy multitasking, the i3-8350K remains a capable option for entry-level performance rigs. For workstation use, the Intel Core i3-8350K is best suited for light productivity like web browsing, office apps, and media editing at smaller scales. Its lack of hyperthreading limits it to 4 threads, resulting in lower multicore scores around 5,837 in Cinebench R23 and 4,342 in Geekbench multicore compared to modern mid-range CPUs. However, the 8 MB of shared L3 cache and high clock speed help it stay responsive in lighter creative workflows. Cost effectiveness is where the i3-8350K shines, especially considering its original $168 launch price and availability on affordable 300-series motherboards.
  1. It supports Intel Socket 1151, compatible with B360, H370, and Z370 chipsets, giving users flexible motherboard options.
  2. Despite being a few generations old, the Intel I3-8350K remains a smart pick for budget-conscious builders needing reliable 1080p gaming performance.
  3. While newer CPUs offer better efficiency and core counts, the Core i3 8350K still holds up as a no-frills, high-clocking workhorse for entry-level systems.
