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.

Cons: -Price

Overall Review: If you want to do video rendering or anything that can use 32 threads this processor is the best around.

What a beast 4/1/2020 3:02:54 PM

Pros: Many cores
Many threads
High clock rate

Cons: A bit pricy but very cheap compared to team blue

Overall Review: I hesitated at first between the 3950x and 3800x and finally went for the 3950x and dont regret it. I was able to easily overclock all cores at 4.3 ghz and can hold it for ever

I reused the Rosewill VIPER Z case and Corsair HX750 power supply from a previous build. I replaced all of the case fans and needed to buy an extra cable for the second 4-pin CPU power connector, The Roswell case has seven 2.5"h disk drive slots. I choose the motherboard because it had 8 6GB SATA ports for the seven drives and one DVD drive.

Incredible CPU! 3/26/2020 3:40:40 PM

Pros: 16C / 32T. Mic drop.

Cons: At present, it's a bit of a budget buster.

Overall Review: No problems as a drop-in upgrade into my existing MSI X370 Gaming Pro Carbon. I did require the latest BIOS update, of course. However, after updating my BIOS it was a simple, drop-in upgrade that I've been super pleased with since. Nice to see AMD on top again these days.

Is what it is... Amazing! 3/24/2020 8:42:16 PM

Pros: Amazing cpu!
"it just works"

Cons: 0
it's not hot
it's not slow
It's not the 3970X?

Overall Review: To those that believe this is too much cpu In monster hunter I have seen as much as 70% usage spikes and as we progress forward in games this only going to become more the norm. This is while using a 14 cas trident Z neo 16gb kit. This thing is freaking amazing! 100/10 would buy again! we live in the era of threads now!

Outstanding Performance! 3/22/2020 10:33:55 PM

Pros: You pay a pretty penny, but it’s worth it if you’re looking for processor that can provide performance for gaming and for streaming/rendering.

Cons: My first one had to be RMA’d because it wouldn’t even boot. Newegg was fast at replacing it though.

The price is high, but it’s kinda expected at this point.

Overall Review: I would definitely recommend this for anyone who works and games on their rig, but for strictly gaming I’d say stick to a 3600 or better.
