They kind of arbitrarily decide what's "effective" or not. When they mention "effective FPS" or "effective speed", they're referring to a proprietary system they came up with that they haven't explained to anyone. They say high average FPS isn't indicative of a realistic experience, which is true, but then they don't explain what they actually mean with "effective FPS". They explain what 0.1% and 1% lows are, and they even have math for that, but no such thing exists for their "effective fps" metric. There's also things like this from their "effective CPU speeds" page:I don't see any reason to distrust their benchmarks, I doubt they have time to hand-sort every benchmark and cherry-pick from thousands of runs to add a -3% anti-AMD bias.
Updates
Our indices are based on today’s performance requirements, we don't predict the future.
July 2019
We reduced the contribution from thread counts higher than eight. The 32-core AMD 2990WX moved from first position to 48th. Meanwhile the 8-core Intel 9900K moved from 7th to first position.
Smear campaign
Within hours of the July 2019 changes, userbenchmark was subjected to an intense and coordinated smear campaign, increased cyber-attacks and personal threats by parties claiming to be AMD fans (for the record, no other brand “fans” exhibit this behaviour). Their very specific demand was to rebalance our CPU Effective Speed in AMD's favour.
November 2020
During the Ryzen 5000 release event, as well as discussing the importance of single core performance and CPU latency, AMD provided benchmarks for 10 games of their choice. According to AMD's official figures, UserBenchmark overestimates Ryzen 3000 by ≈ 5%. Meanwhile, AMD "fans" continue to smear UserBenchmark via an army of anonymous accounts on reddit, youtube, forums and deal sites.
The link about them saying they overestimated AMD is funny because when you go to it, it's actually them saying they underestimated Intel by 5%, but maybe they thought it would sound like they're being generous to AMD by phrasing it like that.
