Average Bench: 87.5% (69th of 1316)

Based on 36,581 user benchmarks.  Device: 178BFBFF00870F10 Model: AMD Ryzen 9 3950X 16-Core Processor

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]

Let me get this straight, the 3950x is NOT a CPU a gamer or a streamer would want. The 3950x is made for video editing, running VMs, servers and even mining. It has the most powerful multi-core performance for a consumer processor. For streamers, the new NVENC encoder on the latest Turing GPUs is able to match CPU x264 quality so having a high core count CPU for streaming is no longer a requirement. With NVENC, you can stream smoothly even with the 6c/6t 9400F. Running two or three programs in the background while gaming is hardly demanding for multi-threaded, multi-core CPU these days. If most of your daily usage consist of gaming and streaming, look elsewhere, such as the 9900k or 9700k where they will give you more headroom for a faster GPU if you happen to upgrade in the future while also being much cheaper. The 3950x also makes lots of sense if you plan to edit and render videos all day long.—Jan '20

most powerful am4 processor 2019 year . 16 core

Offered pretty much what was previously regarded as HEDT grade (16 core 32 thread, huge amount of cache and high clock) at lower prices, is more accessible to high end market and can be slotted to mainstream socket.

Honestly, this is lookin to be the best one by Ryzen yet

Like it or not, but this is the best CPU so far. It has perfect all-round performance and for those who want future proof...next 5 to 10 years the regular consumer or even prosumer will be just fine or better. 4 years ago 4 cores were super and 8 cores were "You don't need it, nothing will use their capabilities". Right now the same story, but 8 cores to 16 cores. Even Intel's flagship 10900K is 10 cores already. Hugely recommendation to everybody, who hasn't decided yet. Gaming is flawless with 2080 Super and on 4K res everything is silky smooth. It just works great with everything.
