Intel Core i3-10100 vs Intel Core i5-11400

The Intel Core i3-10100 (Comet Lake S, Q2 2020) and the Intel Core i5-11400 (Rocket Lake S, Q1 2021) are Intel desktop processors, both manufactured using the 14 nm process.

The Intel Core i3-10100 is aimed at basic applications and offers 4 cores, 8 threads, 6 MB Level 3 Cache, 43 GB/s memory bandwidth, and PCIe 3.0 with Intel UHD Graphics 630. The Intel Core i5-11400 targets the mainstream segment and features 6 cores, 12 threads, 3 MB Level 2 and 12 MB Level 3 Cache, 51 GB/s memory bandwidth, and the newer PCIe 4.0 standard with Intel UHD Graphics 730.

In benchmarks, the Intel Core i5-11400 shows significantly more than 10 percent higher values in both single-core and multi-core performance, making it superior for multitasking and more demanding software. For gaming, the Intel Core i5-11400 clearly has an advantage due to its core count, improved single-core performance, and PCIe 4.0.

Both CPUs have a base TDP of 65 watts, although the Intel Core i5-11400 can consume more power under load and may require more robust cooling. The Intel Core i3-10100 is the more cost-effective option for systems with basic requirements. The Intel Core i5-11400, with its significantly higher overall performance, offers a better price-performance ratio for more demanding users who engage in gaming, content creation, or intensive multitasking.
