 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, UserBenchmark's data exposes youtubers that 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 dedicated 13 years to publishing real-world data which collectively saves our users millions.
The Best.
