The i7-2600K Sandy Bridge processor is two generations old and nearly three years out of date. The numerous owners of this superb processor should feel in no hurry to upgrade as it's still one of the fastest consumer processors, even by today's standards. The benchmark figures indicate that in terms of real-world performance this processor is only 5% slower than the third generation Ivy Bridge i7-3770K, not bad considering its age. That said new buyers will find both better energy efficiency and marginal performance improvements elsewhere. [Feb '12 CPUPro]

I originally wanted an i5-12600 but unfortunately, it was not available so I settled for a 12400. It's really affordable and the performance is great. [Nov '22 arvinjason]

 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.
