Core i3-10300 Details

The Intel Core i3-10300 stands out for its strong single-core performance, ranking #366 in single-core benchmarks with a score of 5784. This places it among the top tier of mainstream desktop processors for tasks that rely heavily on individual thread performance, such as gaming and general productivity. Despite being a mid-tier part, its single-core score exceeds that of several high-end desktop CPUs from the same era, including the Core i7-4790K and Xeon W-2155.

Launched in April 2020, the Core i3-10300 is based on Intel’s Comet Lake architecture and built on a 14 nm process. It features four cores and eight threads thanks to Intel Hyper-Threading, allowing it to handle multithreaded workloads efficiently. The processor operates at a base frequency of 3.7 GHz and can boost up to 4.5 GHz, depending on the workload. It includes 8.583 MiB of L3 cache, 0.244 MiB of L2 cache, and 0.061 MiB of L1 cache, ensuring fast access to frequently used data.

The Core i3-10300 is designed for the Socket 1159 platform, with a TDP of 62 W, making it power-efficient for a desktop CPU. It supports DDR4 memory with a maximum speed of 2666 MT/s over a dual-channel memory bus, delivering a memory bandwidth of 42.7 GB/s. The processor also supports PCIe 3.0 with 16 lanes directly from the CPU, enabling fast connectivity to storage and expansion devices.

Integrated into the Core i3-10300 is Intel’s UHD Graphics 630, a capable GPU for light gaming and multimedia tasks. While not intended for high-end graphics, it supports up to three displays and offers decent performance for everyday use. The processor also includes support for advanced technologies such as AVX, AVX2, AES-NI, and Intel Virtualization Technology, making it suitable for virtualization, encryption, and media encoding.

In multicore performance, the Core i3-10300 scores 4996, placing it at #646 overall. While this is competitive with mid-range processors like the Xeon E3-1280 v5, it trails behind modern high-end CPUs. Its overall score of 5469 ranks it #501, indicating it is well-suited for entry-level to mid-range desktop systems where balanced performance is needed. It is a capable choice for budget builds, office computing, and light content creation.

As of March 2026, the Core i3-10300 remains relevant for users who prioritize single-threaded performance and cost-effective computing. While newer processors offer better multicore capabilities and higher efficiency, the Core i3-10300 holds its own in single-core workloads and offers solid value for everyday use.
