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i5-2500K is a second generation Sandy Bridge processor which is currently two generations old and nearly three years out of date.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 Ryzen 7 3800X is an 8-core, 16-thread high end desktop Zen 2 processor, built on AMD’s seminal 7nm manufacturing process. It has a boost clock speed of 4.5 GHz, overtaking the previous Zen+ flagship, the Ryzen 7 2700X, by 200 MHz and around 16% in terms of effective speed. The 3800X is available at launch for $399 USD alongside four other new Zen 2 processors, including the similarly specified Ryzen 7 3700X. The main differences between the 3800X and 3700X being an extra 100 MHz of boost clock frequency on the 3800X and extra TDP headroom (105W for the 3800X versus 65W for the 3700X) for a $70 USD premium. The 21% higher release price translates to just a 2% higher effective speed over the 3700X. The 3800X is in direct competition with Intel’s i7-9700K, benchmarks show that, when overclocked, the 3800X is 10% worse for gaming but 30% faster for 64-core processing. The 3800X is also 15% ($50 USD) more expensive than the i7-9700K. Additionally, the 3800X's memory controller, although significantly improved over previous Ryzen iterations, still has limited bandwidth and high latency which can also impact gaming. Like the other third generation Ryzen processors, the 3800X is compatible with the new PCIe 4.0 enabled X570 chipset as well as the 400 and 300 series motherboards. At $380 USD, the 3800X offers reasonable value for purely workstation tasks such as film production but streamers should look elsewhere. Streaming with dedicated hardware such as NVENC or a separate stream PC will nearly always result in fewer dropped frames. [Jul '19 CPUPro]
