The Intel's specially binned i9-9900K, featuring 5GHz all core boost and base clock of 4GHz. This CPU is one of the most powerful Intel CPU in term of day-to-day and gaming performance but with TDP of 127W, bulky air cooler or 240mm AIO is recommended to make sure the CPU doesn't overheat, and open loop liquid cooling if you want to OC. [Jun '20 ColdSpy]

MORE DETAILS

The Intel Core i5-4590 is a slightly upgraded version of the i5-4570. The two processors are identical apart from a 100 MHz increase in base and turbo frequencies. Needless to say the two processors have almost identical effective speeds which is a little disappointing as Intel has simply re-released a near identical product. From a value for money perspective the 4590 does fare reasonably well although it probably has more multi-core horsepower than most use cases demand. For the majority of users, at stock clocks, the G3258 provides comparable performance but with a few simple BIOS adjustments the G3258 can be clocked up to 4.3 GHz where, even at half the price, it destroys the i5-4570 in single and dual core workloads. [Sep '14 CPUPro]
