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]
