Average Bench: 88.7% (154th of 1456)

Based on 16,922 user benchmarks.  Device: 178BFBFF00870F10 Model: AMD Ryzen 9 3900XT 12-Core Processor

The XT series of Ryzen CPUs barely outperform their cheaper X and non-X counterparts: 3600, 3600X, 3800X, 3900X. Outside of encoding workloads such as UserBenchmark 64-core, Cinebench, Blender-CPU and Handbrake-CPU the Ryzen architecture remains limited by relatively high latency and the associated gaming bottleneck (frame drops). Dedicated hardware such as NVENC or QuickSync remains far more efficient than CPU cores for encoding. CPU based encoding is akin to using hair clippers on a lawn. The best value CPU amongst the Ryzen range is the 3300X which is the first design to focus on delivering lower latency, and therefore better performance where users need it, rather than “Moar Coars”. Aside from the army of anonymous influencers on social media (reddit, forums, youtube etc.), users will be hard pressed to find rational arguments that favor the XT variants over their cheaper predecessors. [Jul '20 CPUPro]

 Frequently Asked Questions

 Best User Rated

Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. 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, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
