Intel Core Ultra 9 Processor 285K vs Intel Core i5-14600K
The Intel Core Ultra 9 Processor 285K is the premium option here, boasting a staggering 24 cores and a max Turbo clock of 5.7 GHz. Meanwhile, the Intel Core i5-14600K, while more affordable, still competes with 14 cores and impressive gaming performance that beats previous gen i9s. In my testing, the Ultra 9 shines in multi-threaded applications with its hefty 76MB cache, which means faster data retrieval.
