The History of AMD RYZEN 9 3900x: What to Know
The AMD Ryzen 9 3900X is the best mainstream processor available. You won’t find a better processor without stepping up to the HEDT market, with multi-threaded performance that destroys everything in its path and PCIe 4.0 support.
This processor has 12 cores and 24 threads. In applications with many threads, the extra cores make a big difference. The Ryzen 9 3900X has a boost frequency of 3.8GHz to 4.6GHz. It operates at a 3.8 GHz base frequency and a 4.6 GHz boost frequency. If you use your PC for work, content creation, or any other productivity task that requires a fast CPU, the Ryzen 9 3900X delivers, and the power efficiency improvements are incredible.
The AMD Ryzen 3rd Generation and the Zen 2 architecture are notable for being the first to bring 7nm processors to the mainstream. But there’s much more to it than just a smaller manufacturing node under the hood.

The most significant and straightforward improvement is the massive increase in IPC, or instructions per clock. AMD claims that it was able to boost IPCs by up to 15% in its 3rd Generation Ryzen chips, which helps to explain why single-core performance sees such a boost over something like the AMD Ryzen 7 2700X.
Because of the increased IPC improvements and the massive turbo boost of 4.6GHz, AMD’s processors are now competitive in single-core performance, which has long been a weak spot for the company.
Between the cIOD and CCD, the interconnecting Infinity Fabric (Fclk) has been decoupled from the memory controller (Uclk), allowing significantly increased memory capabilities with 3rd Gen Ryzen. Over 4,200MHz DDR4 is rated “with ease,” and even 5,133MHz kits are available. The sweet spot, however, is around 3,600/3,733MHz. Beyond that, Uclk switches from a 1:1 Uclk/Flck ratio to a 2:1 Uclk/Flck ratio, increasing overall latency.
The switch to 7nm silicon, on the other hand, has allowed for a larger cache size. Because the 7nm CPU cores are contained within their chipsets, AMD was able to cram a lot more in – 64MB of L3 and 6MB of L2, for a total of 70MB of cache. This is a huge deal because it enables much faster performance. Another benefit of AMD Ryzen, and specifically the X570 chipset, is the long-awaited addition of PCIe Gen 4 support.
The AMD Ryzen 9 3900x is a fantastic all-arounder, and AMD has made significant improvements in some of the areas where it previously lagged. While AMD still has work to do in the future to improve total single-threaded performance and memory performance, they’re hot on Intel’s tail.
The chip outperforms Intel’s mainstream desktop designs in multi-threaded performance, but it can also compete with the lowest rung of Intel’s more specialized HEDT platforms. Even AMD’s Threadripper line of processors is rendered obsolete below 16 cores.
The Public Response
With the introduction of the first Ryzen 9 processors in 2019, AMD increased its ability to compete with Intel’s Core i7 and Core i9 chips. The Ryzen 9 and Core i9 are both compelling options if you’re looking for the ultimate high-performance, consumer-grade desktop CPU. However, new second-generation Ryzen 9s in the Ryzen 5000 Series (led by the ferociously powerful 16-core AMD Ryzen 9 5950X) have fought back against the latest Core i9s in 2021.

The Ryzen 9 3900X has 12 cores compared to the Core i9-9900K’s eight, so it has an advantage right away, at least in terms of raw specs for multi-threaded workloads. If all other factors are equal, the more cores a chip has, the better it can handle complex workflows from modern software applications, often designed to assign tasks to as many CPU cores and threads as possible.
The most popular and publicly loved features of the AMD Ryzen 9 3900x include its compatibility with X470 motherboards, and that it has PCIe 4.0 support. It also comes with exceptional performance, and at the same price, it outperforms Intel, thus giving it an edge over Intel. In AMD Ryzen 9 3900x, a desktop platform, there are 12 cores and 24 threads!
