Core i3-8300 Details

As of March 2026, the Intel Core i3-8300 remains a relevant entry in the desktop processor lineup, particularly for users prioritizing integrated graphics and efficiency. Launched in February 2018, this processor is based on the Coffee Lake architecture and features a 14 nm manufacturing process. With a base clock of 3.7 GHz and a locked multiplier, it delivers strong single-threaded performance despite its modest multicore capabilities. The chip is built on the LGA-1151 socket and operates at a 62 W TDP, making it suitable for mainstream desktop builds without demanding thermal solutions.

The Core i3-8300 features four cores and four threads, with a 8 MB L3 cache and 1 MB of L2 cache. It supports DDR4-2400 memory in a dual-channel configuration, delivering a maximum memory bandwidth of 35.76 GiB/s. The processor includes Intel’s UHD Graphics 630 integrated GPU, which offers up to 1150 MHz boost frequency and supports up to three displays. This makes it a viable option for light multimedia tasks and casual gaming, though discrete graphics are recommended for more intensive workloads.

In terms of supported features, the Core i3-8300 includes essential technologies such as AVX, AVX2, AES-NI, and Intel’s virtualization extensions (VT-x and VT-d), enabling efficient virtual machine performance and data encryption. It also supports ECC memory, a feature often found in business and server environments, highlighting its versatility. Despite lacking Hyper-Threading, the processor delivers competitive single-core performance, as evidenced by its single-core score of 5398, placing it at rank #643 among 2060 processors.

Benchmark results reveal a balanced performance profile. The Core i3-8300 achieves an overall score of 5136, ranking #763, and a multicore score of 4742, ranking #916. While it trails behind modern high-end processors, it competes effectively with several mid-range and older generation CPUs, including the Ryzen 3 2300X and Core i7-4700MQ. Its standout strength lies in single-core performance, which outperforms many of its contemporaries and remains competitive in applications that rely heavily on clock speed and instruction throughput.

Given its age, the Core i3-8300 is best suited for budget-conscious users, light office work, media consumption, and entry-level content creation. It offers a solid foundation for systems where discrete graphics are not required and energy efficiency is a priority. While it no longer represents cutting-edge performance, its enduring value stems from its reliability, integrated capabilities, and compatibility with mainstream 300-series chipsets.
