Even though the Core i9-9900K is the fastest processor of this generation, its high price makes it out of reach of most people. That is why the most popular LGA 1151 processor is the Core i5-9400F, which comes with six cores and six threads. It is a locked processor, which means that it cannot be overclocked, but the high clock rates of this processor are enough for most games. Moreover, it does not come with an integrated graphics card, so it costs lower than Core i5-9400.
