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i5-2500K is a second generation Sandy Bridge processor which is currently two generations old and nearly three years out of date.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]

MORE DETAILS

The 8 core, 16 thread 2700X is AMD’s second generation Ryzen 7 flagship following in the wake of the Ryzen 7 1800X which continues to offer excellent multi-core value for money. This new Pinnacle Ridge processor features the Zen+ architecture with 12nm lithography compared to 14nm previously. Whilst there is no increase in the number of cores, the stock base / boost clocks appear to have received a bump up to 3.7 / 4.3 GHz from 3.6 / 4.0 GHz. The 2700X is compatible with both the new 400 series and 300 series of motherboards. Early benchmarks indicate that the 2700X has a slightly greater effective speed than the 1800X, although further benchmarks are necessary to quantify this. The expected launch price of $329 includes a Wraith Prism cooler and is in the same price bracket as the 1800X and Intel’s Coffee Lake i7-8700K. Whilst the 6 core, 12 thread 8700K beats the 2700X in single and quad core performance by about 10%, the 2700X wins on multi-core workloads. PC gaming and desktop performance is generally governed by four or less cores but the 2700X offers unbeatable value for money for workstation users. [Apr '18 CPUPro]
