5 Best Motherboard for Ryzen 9 3900X in 2021 | AMD Desktop Processor

The AMD Ryzen 9 3900 X is the best performance-oriented motherboard in the market currently, it is much more powerful than its Rival the i9-9900k and it has 12-cores and 24-Threads which redefines our meaning of power and our expectations from all standard mainstream desktop PCs.

Whenever the concept of the best gaming processor comes to our mind the name of Ryzen 9 3900X also comes our mind. The main reason behind the Success of this Highly popular microprocessor is that it comes packed with 12 cores and 24 Threads that offer hyperthreading and immense power to the system whereas if we talk about its Rival the i9-9900k it still gets those old standard pack of 8 cores and 16 threads.

All the PC and enthusiasts can get this Ryzen 3000 series CPU as they are now widely present on almost all online platforms as well as at retailers. The AMD Ryzen 9 3900X CPU is a zen2, 7nm fabrication-based processor.

Driving more into its technical Complications this zen 2 CPU offers an upgraded L2 Tag brand predictor and a bigger cache that makes twice the maximum size of the L3 cache and doubles the AVX point performance. If you compare the CPU from all previous-gen Ryzen models, you will notice that this CPU has packed with more density of performance and power, better efficiency, higher cores, and much more cache is given in a smaller case.

AMD had revealed their ultimate Zen architecture brand CPU many years ago and also made the way for their ‘Matisse of ryzen 3000’ series, and since that time they have been doing immense work and launched many Masterpiece microprocessors. After that when the company decided upon the exertion with 2nd-generation Technology-based ryzen processors they included a quicker interaction that matched with the similar 1st-generation Zen plan.

The AMD’s organization planned to grow forward with their Zen-2 design, which AMD stated that presents 15% more directions per cycle that all matched with the benefits of 7nm interaction and more centers in the microprocessor. Also, AMD’s exploration of the PCI-e 4.0 interface on the PC platforms, the ryzen 3000 series chips guarantee a hazardous advancement forward in terms of power and performance.

For the production of top-notch processors like the 3900X AMD has wrapped up everything in a 7nm bow by shifting the storage controller out of the main CPU chipset directly in the second i/o shield and putting both of them into a unified system that ultimately gave way for the dual microprocessor system. If you look at the previous generation models and current-gen ones, you will notice that AMD has made some fairly good changes in terms of L3 sizes and clock speeds. Also the main thing that was changed is pricing.


  • Prices: $480-$485
  • Cores: 12
  • Threads: 24
  • Base frequency: 3.8 GHz
  • Boost frequency: 4.6 GHz
  • Cache (L3): 64 MB
  • Total cache (L2): 6 MB
  • Cooling system: Prism 105 W

During single-threaded workloads, the 3900X can pull to the frequency of 4.6 GHz, and if there are some chances of launching some updates in the firmware system that can show some improvement in the power and performance with an increase of about 50-100 megahertz in the clock speed of the system on single-threaded caseloads.

In 2021 if you are thinking to buy an Intel’s Core i9-9900k it would be a bad choice, seeing the current case scenario the Ryzen 9 3900X is the best deal to go for as it offers much more power and performance and it is more subtle and stable in bearing high-end PC tasks without burning out. The 3900X can handle all modern and triple-A titles of games at 1080p, 1440p, and at 4K as well, but for that, you would need to pair this beast microprocessor with an equally compatible motherboard so that you can enjoy its power to the fullest. With that being said, we have made a list of the 5 best motherboards for ryzen 3900X ranging from the most high-end motherboard to the most budget-friendly ones.


  • More cores and threads.
  • Efficiently fabricated architecture of 7nm
  • Supports PCIe Gen4


  • Most of the applications don’t even require these many cores.
  • It is not that much efficient in terms of overclocking.
