 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate countless reddit accounts. UserBenchmark challenges their narrative so they attack our reputation with a co-ordinated charade.
Why don’t PC brands endorse UserBenchmark?
PC brands make a lot of profit on flagships like the 4090, 14900KS, and 7950X3D. 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 exposes the youtubers that are paid to promote overpriced/inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ reviews on trustpilot are mostly written by virgin marketing accounts. Real users aren't incentivized to back brands.
Why is UserBenchmark popular with users?
Instead of chasing sponsorship with billion-dollar PC brands, we've spent 13 years publishing real-world data which collectively saves our users millions.
The Best.
