CPU Comparison
Intel Core i5-7500 vs Intel Core i5-8400
A side-by-side comparison of specs, performance and value. The Intel Core i5-7500 is a mid-range desktop processor launched in early 2017 as a core component of the 7th Generation Kaby Lake family. Featuring four physical cores without Hyper-Threading, it operates at a base frequency of 3.4 GHz and can boost up to 3.8 GHz. Manufactured on Intel's 14nm process, it fits within a standard 65-watt TDP, ensuring broad compatibility with mainstream cooling solutions. The processor was a popular choice for budget gaming builds and office PCs, offering a slight frequency bump over the i5-7400. It integrates Intel HD 630 graphics, capable of hardware-accelerated 4K video decoding, and supports dual-channel DDR4 memory at 2400 MT/s. While it provides snappy single-thread performance for everyday applications, the lack of Hyper-Threading limits its capability in heavily multi-threaded modern workloads. Utilizing the LGA 1151 socket, the i5-7500 remains a viable option for upgrading older systems, though it is outclassed by newer architectures in both efficiency and core count.
