 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketing teams operate large numbers of reddit accounts. Because UserBenchmark’s data often contradicts their marketing spiel, they systematically attack our reputation.
Why don’t large PC brands support UserBenchmark?
PC brands make a lot of money on flagship hardware sales: 4090, 14900KS, 7950X3D etc. We help consumers get comparable real-world performance at a fraction of the cost.
Why don’t any youtubers promote UserBenchmark?
We don't sponsor youtubers, so they have no incentive to praise us. Additionally, brands spend more on marketing weaker products which puts their youtubers at odds with UserBenchmark.
Why does UserBenchmark have so many negative trustpilot reviews?
Trustpilot hosts user-generated reviews in an online community. 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 the last 13 years to providing comprehensive and accurate data to our users. As a result, most of our users return over and over again and collectively save millions every year.
The Best.
