The consistent discrepancies between real-world, reputable benchmarks for AMD CPUs and GPUs, and what gets reported on UserBenchmark, has fascinated me for years.
Beyond their heavily biased descriptions of AMD products, I can prove that it's deliberately manipulated and perhaps other keen eyes noticed it too. I was there the hours/early days of the 9070/XT launch and early results, though varying based on system configs, GPU manufacturer, etc, definitely had the 9070XT in the realm of the 5070ti.
That is, until the results were all removed from UserBenchmark completely - leaving just one extremely anecdotal "benchmark" of each GPU for others to compare, deliberately misleading the public and no doubt affecting opinions and sales. I could hypothesize the kept result for each GPU was among the lower of the benchmarks, but I didn't keep any receipts - maybe next time.
The best we can do is keep spreading the word about the AMD-directed abuse the website spews. Some sort of AMD-lead litigation would be tremendous as proof of deliberately misleading statements should be available and deemed damaging to the brand, given the high level of promotion the site receives overall.
