Built to Perform. Designed to Win.

The World’s Most Powerful 16-Core Desktop Processor*

Everyone deserves a powerful processor. Uncompromising features and smooth performance are finally the standard for every gamer- and artist-oriented system. Powered by the amazing Zen 2 architecture and manufactured using 7 nm process technology, the Ryzen 9 3950X has 16 cores and 32 threads, offering exceptional parallel computing power to handle demanding tasks and multitasking. PCIe 4.0 allows you to take full advantage of the new generation SSDs and next generation graphics cards.

Please note: Cooler Not Included, Liquid Cooling Recommended.

* Testing by AMD performance labs on 09/15/2019, comparing the AMD Ryzen 9 3950X (AMD's fastest 16-core) to the Intel Core i9-9960X (Intel's fastest 16-core), Using the Cinebench R20 single-core benchmark score and Cinebench R20 multi-core benchmark score to measure single-core and multi-core performance for each processor. Performance results may vary. RZ3-72

Amd Ryzen 9 3950x—The New 16-core Desktop Performance Leader
3rd Gen AMD Ryzen Technology

Zen 2—Setting the Bar for High Performance

AMD’s high-performance x86 Core “Zen 2” architecture enables 3rd Gen Ryzen Processors to deliver the highest single-thread and multi-thread performance of any mainstream desktop processor. For gamers and creators alike, that’s mission-critical performance built to help you win.

Compute Efficiency by Design

The "Zen 2" core is a significant update to the historic "Zen" architecture. Now featuring:

  • Up to 15% more instructions-per-cycle
  • 2X L3 cache capacity (up to 32MB)
  • 2X floating point throughput (256-bit)
  • 2X OpCache capacity (4K)
  • 2X Infinity Fabric bandwidth (512-bit)
  • New TAGE branch predictor

Performance and Efficiency for Next-Gen Applications

Cloud computing, enterprise productivity, immersive visual experiences, gaming and streaming all demand increasing computing performance with optimal energy efficiency. From the very beginning, AMD engineers designed the new “Zen 2” core to meet those demands with more core throughput, larger caches, and powerful multi-threading capabilities.

AMD StoreMI Technology*

SSDs are fast, but expensive, and offer minimal capacity. Mechanical hard drives boast large capacity for a low price, but are much slower than an SSD. AMD StoreMI technology combines these two types of storage into a single drive and automatically moves the data you access the most to the SSD, so you get the best of both worlds: SSD responsiveness, and mechanical hard disk capacity with its low price.

* AMD StoreMI Technology is included with every motherboard that features an AMD X399 or 400-series chipset. If you have an AMD X399 or 400-series chipset, you can download AMD StoreMI software for free. If you have a socket AM4 motherboard with a 300-series chipset, you can still enjoy the benefits of storage acceleration with Enmotus FuzeDrive software, exclusively for AMD, for an additional fee.

AMD SenseMI Technology. Technology That Thinks.

AMD introduces SenseMI technology, a set of learning and adapting features that help the AMD Ryzen processor customize its performance to you and your applications. Finally: performance that thinks.

AMD Ryzen Master Utility for Overclocking

Every AMD Ryzen processor is multiplier-unlocked from the factory, so you can personalize performance to your taste. AMD provides the AMD Ryzen Master utility to access this powerful advantage.

AMD Ryzen Master provides up to four profiles to store custom clocks and voltage adjustments for both the Ryzen CPU and DDR4 memory. You can park cores and adjust memory timings, too.

Note: AMD product warranty does not cover damages caused by overclocking, even when overclocking is enabled via AMD hardware.

CPU is a beast 2/22/2020 7:37:58 AM

Pros: -Still using AM4 socket, so current CPU water block was compatible
-Stock clock speeds run nice a cool, even while bench marking. (Using 360mm loop)

Overall Review: If you have the budget, you will not regret this CPU. It's an utter beast of a CPU at 16 cores. My system is so much more stable on this that my old i7. Render times are night and day compared to my old i7. (They obviously should be). Even during some 3DMark bench bench marks, the animations are so much smoother with just the upgrade to this CPU. (With a nice bump in physics score)

Forget the so-called 'Gift' 2/9/2020 4:55:50 PM

Overall Review: Before you can claim your games, you have to have the CPU installed in a working system! No provision for those of us who are buying parts for a new system!

If you can find it, buy it. 1/19/2020 8:41:10 PM

Pros: It is amazingly fast.

Cons: None

Overall Review: TLDR: If you can afford it and actually use the cores but don't need the core count or PCIE lanes of Threadripper then this will serve you well. I have had Ryzen since day one. Upgrading from Ryzen 7 1700 to this was easy since I could drop it into my current motherboard which was already on the latest bios for Ryzen 3000. I have had no issues at stock or PBO. Simply the best mainstream CPU you can buy.

Clock Speeds:
My CPU will occasionally boost to 4.7Ghz when gaming but mostly sticks between 4.3-4.6Ghz. When rendering videos in Davinci resolve the cores that are being loaded are running at 4.1-4.2Ghz. The CPU is only at 50-60% load with my rendering workload so the cores are running rather quick and the voltage is slightly above 1.3v. When rendering videos in resolve I get about 75c on a Noctua NH-D15S with the fans at 1,000RPM. When running Cinebench the cores were at 3.9Ghz and when I did a prime95 test they were at 3.4Ghz (likely due to the AVX workload). Generally the higher the load the lower the voltage and temps. When running the prime95 load it was down to 64c with voltage just under 1v.

RAM:
I have 32GB of DDR4 3000Mhz Corsair Dominator Platinum RAM. With my Ryzen 7 1700 I set the DOCP (XMP) profile and it ran no problem. Trying for 3200MHz on my Ryzen 7 1700 would cause a crash after a while on a hard load. With my Ryzen 9 3950x I was able to keep all the DOCP (XMP) settings that came with the ram and simply set it to 3200Mhz and it has run with no issues. I'm sure I could push it harder with manually timings and whatnot but I care more about stability and have never had much luck overclocking...anything.

Gaming:
It is the fastest Ryzen 3000 CPU you can buy. While hopefully no one buys this solely for gaming, it gets the job done very well in the games I have played. It has made my city simulation speed in cities skylines quick again. I play other games but they are old and I generally run V-Sync or some other capped framerate so it serves me well enough.

Streaming/Recording:
I record gameplay videos from my Xbox One X at 4K with the Aver Media Live Gamer 4K. Recording settings are as follows: 4K 60fps with the YUY2 Decode format, 10Bit, Expanded Colors (0-255), H.264, 240Mbps (240,000Kbps) and it is locked 60 the entire time. When streaming I use OBS 1080p60, Slow Preset, 9000Kpbs to YouTube. Never drops a frame. I can even render videos out in Davinci Resolve and Record at the same time and not max it out with the settings I use.

You really shouldn't have any regrets buying this CPU unless you absolutely cannot find a way to utilize it with your workload or you only game. If you only game you should probably buy a Ryzen 5 3600/Ryzen 7 3700x.

Motherboard was an ASUS Prime B350 Plus bought in 2017 so if you are upgrading from a previous generation Ryzen CPU you can plop it right in assuming your motherboard has the right bios.
