Core i5-8300H Details

Ranking #654 of 2060 in overall performance, the Intel Core i5-8300H presents a compelling case for mid-range mobile computing, particularly for users who prioritize single-core efficiency over raw multicore throughput. Launched in April 2018, this processor belongs to Intel’s Coffee Lake-H family, built on a 14 nm process and designed for high-performance laptops. While no longer cutting-edge by today’s standards, its single-core score of 5531 places it in a competitive tier, ranking #533 in single-core performance across over 2,000 processors. This suggests it remains capable for tasks like web browsing, office productivity, and light content creation, especially when paired with its integrated UHD Graphics 630 GPU.

At the heart of the Core i5-8300H are four cores, enhanced by Hyper-Threading to deliver eight logical threads, a feature that significantly boosts multitasking and multi-threaded application performance. The processor operates at a base frequency of 2.3 GHz, with a maximum turbo frequency of 4.0 GHz under full load—ideal for handling demanding workloads on a transient basis. The 8 MiB of L3 cache helps reduce memory latency, while the 1 MiB of L2 cache and 0.25 MiB of L1 cache ensure fast access to frequently used data. The chip is manufactured on a 14 nm node and is packaged in the BGA1440 format, which limits its upgradeability but allows for a more compact design.

The Core i5-8300H is built with a range of advanced technologies, including Intel’s Turbo Boost 2.0, Enhanced SpeedStep, and Intel VT-x and VT-d virtualization extensions, which are beneficial for developers and users running virtual machines. It supports DDR4-2666 and LPDDR3-2133 memory across two channels, with a maximum capacity of 64 GB and a theoretical bandwidth of 39.74 GB/s. The processor’s TDP is rated at 45 W, with a downclocking option to 35 W, offering flexibility in power management for laptops with varying thermal constraints.

Performance benchmarks reveal a balanced but not exceptional profile. In multicore tests, the Core i5-8300H achieves a score of 4830, placing it #807 in the multicore ranking—just behind several modern Intel and AMD processors, including the Ryzen 5 2400G and the Xeon E3-1230 v5. However, its single-core score of 5531 is notably stronger, surpassing many higher-TDP desktop and server chips, including the Core i7-8559U and the Xeon E5-1630 v4. This suggests that while the i5-8300H is not a powerhouse for intensive rendering or simulation tasks, it excels in applications where single-threaded performance is critical.

The integrated UHD Graphics 630 GPU, while not suited for modern gaming, provides solid basic graphics performance for office applications, video playback, and light photo editing. It supports up to three displays and can boost to 1.0 GHz when needed. With features like Intel’s Advanced Vector Extensions (AVX and AVX2), it offers enhanced performance in compute-heavy applications such as scientific simulations and video encoding.

As of March 2026, the Core i5-8300H remains a viable option for users seeking a reliable, energy-efficient mobile processor for everyday computing, particularly in older laptops or budget-friendly systems where upgrading to a newer platform is not feasible. While it no longer competes with modern high-end mobile CPUs, its combination of strong single-core performance and integrated graphics makes it a durable workhorse for general productivity.
