The 3950X is the 16 core, 32 thread Ryzen 3 flagship. Although this CPU offers server levels of multi-core encoding performance, there are relatively few, if any, consumer use cases for the 3950X. Streamers are better off using dedicated hardware such as NVENC which encodes far more efficiently than any CPU. Gamers are better served by low latency gaming CPUs such as the 9600K for a fraction of the price. For example, comparing these two PCs shows that the 3950X build offers less than half the gaming performance. The only rational reason to put a 3950X in a gaming build is in exchange for sponsorship money. [Feb '21 CPUPro]

This CPU is incredibly well-placed for a refresh. The i9 14900k(640 euros) offers similar performance to the i9 13900KS(800 Euros) while being available for much less money. The new gen motherboards are also much better. So if you were thinking about getting the 13th gen i9 then the 14th gen is a no-brainer since it offers flawless performance for both gaming and productivity tasks. This is especially true since AMD's "equivalent" 7950x3d is haunted by software bugs and "features" such as needing to have Xbox game bar open 24/7 and having their motherboards overvolt and kill the CPUs. [Oct '23 MrNukes]

 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 the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
