Average Bench: 88.9% (42nd of 1257)

Based on 576 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]

AMD are great at selling junk. They pee in the well with fake comments, glorified cheerleaders on youtube and paid magazine reviews. My POS PC still crashes randomly. Everybody needs to call the rats out instead of letting them get away with it.
