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i5-2500K is a second generation Sandy Bridge processor which is currently two generations old and nearly three years out of date.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 AMD Ryzen 7 1700 is the least powerful of three new Ryzen 7 CPUs. The 1700 model has base and turbo clocks of 3.0 and 3.7 GHz respectively. Both of its more expensive siblings, the 1700X and 1800X, have higher clocks but they also have TDPs of 95 watts whereas the 1700 is rated at just 65 watts. Comparing IPC between Ryzen and Kaby Lake shows that Kaby Lake leads by a maximum of 9% which is great news for workstation users as this allows the 1700 to beat Intel's 6850K in multi-core workloads at almost half the price. Although the 1700 has great IPC it's somewhat limited by its relatively low (by Kaby Lake standards) clock speed which holds it back a little in both gaming and desktop workloads. For multi-core workstation use, the Ryzen 7 1700 represents the best value for money we have ever seen. [Mar '17 CPUPro]
