Don't be fooled by the "i7" name. It performs like a Core 2 Quad with Hyperthreading. Overall performance is fine, but the processor is so insanely power hungry that your power bill will actually take a small hit. Similar to FX processors, it is a glorified space heater with bad IPC. [Apr '20 Viriyena]

I have been running an i5-2550k since 2012. With modest overclocking it is only 20% slower in single core processing than the 8th Gen i5's, giving me no reason, even 5 years later, to upgrade. [Oct '17 usbserial]

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate countless reddit accounts. UserBenchmark’s data exposes their marketing spiel so they systematically attack our reputation.
Why don’t large PC brands support UserBenchmark?
PC brands profit greatly from flagship hardware like the 4090, 14900KS, and 7950X3D. We help users get similar real-world performance for less money.
Why don’t any youtubers promote UserBenchmark?
We don't sponsor youtubers, so they have no incentive to praise us. Moreover, brands pay youtubers extra to promote inferior products but UserBenchmark’s data exposes them.
Why does UserBenchmark have so many negative trustpilot reviews?
Trustpilot hosts user-generated online reviews. It's obvious that the 200+ UserBenchmark reviews, are mostly written by virgin marketing accounts. Real users aren't interested in promoting billon-dollar brands.
Why is UserBenchmark so popular with users?
Instead of pursuing lucrative sponsorships with billion-dollar PC brands, we have dedicated 13 years to publishing accurate real-world data. As a result, our users save millions every year and they keep returning.
The Best.
