Core i3-8100 Details

With a TDP of 65 W, the Intel Core i3-8100 stands out as an energy-efficient desktop processor designed for mainstream computing tasks. Launched in October 2017, this CPU is based on Intel's Coffee Lake architecture and built on a 14 nm process node, which was standard for its generation. Despite its age, the Core i3-8100 remains relevant for entry-level systems due to its balanced performance and integrated graphics. It features four cores and four threads, operating at a base frequency of 3.6 GHz with no turbo boost capability, reflecting Intel's strategy of offering stable performance over aggressive overclocking. The processor supports DDR4-2400 memory across a dual-channel interface, with a maximum capacity of 64 GB and a memory bandwidth of 35.76 GiB/s, making it suitable for general productivity and light multimedia applications.

The Core i3-8100 includes a 6 MB L3 cache and a 1 MiB L2 cache, supporting efficient data access for multi-threaded workloads. It is packaged in the FCLGA-1151 socket, compatible with 300 series chipsets, and supports PCIe 3.0 with up to 16 lanes directly from the CPU. The integrated UHD Graphics 630 GPU provides a base frequency of 350 MHz and can boost up to 1.1 GHz, supporting up to three displays and offering basic multimedia and light gaming capabilities. This makes the processor ideal for systems without a discrete graphics card, such as small form-factor PCs or office workstations.

In terms of features, the Core i3-8100 supports advanced instruction sets including AVX, AVX2, and AES-NI, enhancing performance in encryption, video encoding, and scientific computing. It also includes hardware virtualization technologies like Intel VT-x and VT-d, enabling efficient virtual machine operation, along with Intel Secure Key and TXT for enhanced security. ECC memory support adds reliability for mission-critical environments, although this is more relevant in server or workstation contexts.

Benchmark results place the Core i3-8100 with an Overall Score of 5,283, ranking it #630 out of 2,060 processors, and a Singlecore Score of 5,536, ranking #529. Its Multicore Score of 4,903 positions it at #720, indicating strong single-threaded performance relative to its class but limited scaling in multi-core workloads. Compared to similar processors, it slightly outperforms the Core i5-9400F and Core i5-8400H but falls behind the Core i7-6800K and Xeon E-2288G. While it is not a high-performance option by today’s standards, it remains competitive in entry-level and budget builds.

As of March 2026, the Core i3-8100 is best suited for users seeking a reliable, low-power CPU for everyday tasks such as web browsing, office applications, and media playback. Its integrated graphics reduce the need for a discrete GPU, making it ideal for compact or cost-sensitive systems. While newer generations offer significantly higher performance, the i3-8100’s longevity and efficiency ensure it remains a practical choice in legacy or value-oriented setups.
