CPU Comparison
Intel Core i5-4670S vs Intel Core i5-9400F
A side-by-side comparison of specs, performance and value. The Intel Core i5-4670S, launched in June 2013, is a quad-core desktop processor designed for users who need strong performance within a constrained thermal envelope. As part of the Haswell generation, it features a 65-watt TDP, making it significantly more power-efficient than the standard 84-watt i5-4670. Operating at a base frequency of 3.1 GHz and turbo boosting up to 3.8 GHz, it delivers snappy single-threaded performance suitable for gaming and demanding applications. Built on a 22nm process, it houses 1.4 billion transistors and 6MB of L3 cache. The inclusion of Intel HD 4600 graphics ensures smooth 4K video playback and basic gaming capabilities. This processor was highly sought after for small form factor builds and home theater PCs where heat and noise reduction were priorities. It remains a capable chip for legacy systems and budget gaming setups.
