Intel Core i5-8400 2.8 GHz @ TechPowerUp
 

Core i5-8400 is Intel's most affordable option to go beyond quad-core on the desktop. With a price point of $190 it is only half the price of Core i7-8700K, but delivers nearly the same performance in games and can also compete with Ryzen 6c12t processors thanks to its good single-threaded performance and high boost clock.
