 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. UserBenchmark exposes their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make lots of money on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our 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 don't care about big brands.
Why is UserBenchmark popular with users?
Instead of pursuing sponsorship with billion-dollar brands, we've spent 13 years publishing real-world data.
The Best.
