The i5-2500K is a second generation Sandy Bridge processor which is currently two generations old and nearly three years out of date. The many users that had the good sense to purchase this processor should feel in no hurry to upgrade as it's still no slouch, even by today's standards. The benchmark figures indicate that, even at stock clock rates, in terms of real-world performance this processor is approximately 20% slower than the best currently available, not bad considering its age. Given that the 2500K has an unlocked multiplier upping its performance by 10% with stock cooling should not pose much of a problem for the majority of owners. Here is a detailed performance comparison of the 2500K vs 4670K.  [Jul '13 CPUPro]

The Ryzen 5 1600X is the flagship processor from AMD's latest generation of Ryzen 5 processors which feature the Zen architecture. Following on from last month's release of the Ryzen 7 series, the Ryzen 5 series is positioned as a less expensive mid-performance alternative to Intel's i5 mainstream offerings. Once again, AMD excels in multi-core technology. Like the Ryzen 5 1600, the 1600X features 6 cores and 12 threads, but has roughly 11% higher clock speeds (out of the box) for a 14% premium. Like all Ryzen CPUs the 1600X is unlocked. The 1600X is the only Ryzen 5 CPU with a TDP of 95W, the 1600, 1500X and 1400 all have 50% lower power consumption of 65W. Due to its high thread count, UserBenchmarks show that at stock clocks the 1600X outperforms the i7-7700k on multi-threaded tasks by 23%, but it lags behind by 23% for single and 14% for quad-core performance. The 1600X is priced keenly at $249 so a more appropriate CPU comparison is the i5-7600k where the 1600X wins on stock multi-core by a whopping 81%. The 1600X does represent great value for workstation users that also game but its $30 cheaper sibling, the 1600 (non x version), which includes a cooler and has great overclocking potential out of the box is arguably the the value king in this segment. [Apr '17 CPUPro]
