The Core i7-4770K is Intel's fourth generation (codename Haswell) flagship processor in the hugely successful Core range. It's not surprising that the 4770K sets a new Real World Performance index record, besting its predecessor by just over 9%. The 4770K also tops out in the remainder of our benchmarks setting new highs of 10020 and 2164 in the PassMark and PassMark Single Thread tests which equates to roughly an 8% overall performance increase over the 3770K. With a TDP of 84 watts, power consumption has increased slightly over the 3770K. The new Core i7-4770K demonstrates around an 8% performance increase over its predecessor the 3770K but it costs 12% more. As a result, at least until prices drop, this processor represents marginally worse value for money than the 3770K. [Jun '13 CPUPro]

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]
