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i5-2500K is a second generation Sandy Bridge processor which is currently two generations old and nearly three years out of date.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

Intel’s tenth gen, six-core i5-10600K is one of the fastest consumer CPUs currently available. Out of the box, its maximum all core frequency is 4.5 GHz, but a simple overclock allows all 12 threads to hit 5.0 GHz. Although a new Z490 (LGA1200) motherboard is required, Intel have indicated that LGA1200 will remain compatible with Rocket Lake CPUs which are due later this year. The eight-core Ryzen 3700X currently competes in the 10600K’s price bracket. CPU based encoding is akin to using hair clippers on a lawn but If dedicated hardware such as NVENC or QuickSync is not an option, the 3700X can outperform the 10600K in encoding workloads such as UserBenchmark 64-core, Cinebench, Blender-CPU and Handbrake-CPU. Meanwhile, the 10600K is better for almost everything else. Currently, the real problem with the 10600K, and much of the Comet Lake line up, is availability. Whilst there was a paper launch in Q2 2020, at the time of writing, the 10600K is still largely unavailable for purchase. In order to achieve better value for money, without compromising on gaming performance, it is necessary to consider the older generation 9600K which is 26% cheaper and offers similar gaming performance. [Jun '20 CPUPro]

 Frequently Asked Questions

 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.
