The Intel Core i5-7600K and i5-8400 are Intel equivalents to the Ryzen 5 1600, though performance varies; the i5-7600K was initially faster in games, while the i5-8400 was similar or slightly faster, with the Ryzen 5 1600 offering superior multi-threaded performance and better value

The Intel Core i5-10400/10400F and Intel Core i5-9600K are considered equivalent to the Ryzen 5 3600 in terms of performance, but with some key differences. The Ryzen 5 3600 offers a significant advantage in multi-threaded tasks due to its 12 threads, compared to the 6 threads of the 9600K. However, the 9600K was faster for gaming upon release, though the 3600 has since shown better gaming performance in newer titles. 

The closest Intel equivalents to the AMD Ryzen 5 5600 are the Intel Core i5-12400F and the Intel Core i5-13400F. The i5-12400F is a strong competitor, offering similar core/thread counts and comparable performance in many scenarios, especially at lower resolutions. The i5-13400F is a newer and faster option, though the Ryzen 5 5600 is more power-efficient. 

The Intel Core i5-13400/F and Intel Core i5-14400/F are the most comparable Intel equivalents to the Ryzen 5 7600, offering similar multi-threaded performance thanks to their hybrid architectures, though the 7600 generally provides superior single-core and gaming performance, especially in esports titles. The Ryzen 5 7600 is newer, more power-efficient, and uses the AM5 platform for better future upgradability, while the Intel options offer platform flexibility with both DDR4 and DDR5 support and more total cores
