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i5-2500K is a second generation Sandy Bridge processor which is currently two generations old and nearly three years out of date.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 Intel Core i9-10850K is one of the best valued high-end CPUs from Intel in the past few years. Essentially, the 10850K is a worse binned 10900K, meaning that it may be a hundred or two megahertz slower than the 10900K and may not overclock as well as a standard 10900K. Otherwise, the 10850K is nearly identical to the 10900K. The 10850K is a very strong gaming and workstation CPU. With a sub-$400 price-tag, the 10850K has a similar pricing to the Ryzen 7 5800X. Gamers who want the faster overall gaming performance should go with the Ryzen 7 5800X, while users who want the best overclocking and a slightly better workstation/multi-core performance may want to stick with the 10850K. Note that Intel will be switching to a new chipset with their 12th generation Alder Lake processors, so the upgrade path is limited to Intel's 11th generation Rocket Lake processors, which is mostly not worth the upgrade. Also, as of Q1 of 2020, the 10900K remains $75-100 more expensive than the 10850K. There is just not enough performance gain for most users to justify the extra cost, so most users would be better off with a 10850K. At the end of the day, the 10850K is still a very solid choice for anyone who wants a high-performing intel processor that will last for a good few years before really needing a upgrade.  [May '21 NorthStar]

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
