The Intel Core i3-9300 was a desktop processor with 4 cores, launched in Q2 2019. It is part of the Core i3 lineup, using the Coffee Lake Refresh architecture with Socket 1151. The Core i3-9300 operates at a base frequency of 3.2 GHz and does not support Turbo Boost technology. Intel manufactured the Core i3-9300 on a 14 nm++ production process, offering improved power efficiency and performance over previous generations. With a TDP of only 35 W, this processor is energy-efficient and suitable for compact systems with basic cooling solutions.

The Core i3-9300 features 8 MB of Intel Smart Cache (L3 cache) to enhance performance in multi-threaded workloads. It supports DDR4 memory with a dual-channel interface, running at speeds up to 2400 MHz. ECC memory is not supported, as this is primarily a consumer-grade processor. For communication with other system components, the Core i3-9300 uses a PCI-Express 3.0 connection.

Unlike higher-end Core i5 and i7 models, the Core i3-9300 does not support Intel Hyper-Threading, meaning it has 4 cores and 4 threads. Additionally, the multiplier is locked, restricting overclocking capabilities. Integrated Intel UHD Graphics 630 is included, eliminating the need for a discrete graphics card for basic display output. Hardware virtualization (Intel VT-x) is supported, improving virtual machine performance, though advanced virtualization features like VT-d are not available.

This processor is ideal for general computing, office tasks, and light multimedia use, offering a balance of efficiency and performance in an affordable package.
