The processor with 12 cores and 24 threads belongs to the advanced Ryzen 9 Matisse line, in which AMD has collected its best mid-2019 solutions designed for the mainstream Socket AM4 platform. The CPU is the carrier of the Zen 2 microarchitecture, created using a 7nm process technology. In the base mode, the core clock speed is 3.8 GHz, and due to the Precision Boost 2 technology, it increases by 800 MHz, reaching 4.6 GHz.
The AMD 3900X BOX processor also received an unlocked multiplier, which leaves room for experimentation for overclocking enthusiasts. The advantages of the model include increased to 64 MB cache memory of the third level, support for the accelerated version of the PCI Express 4.0 bus and DDR4-3200 format "RAM", which allows you to assemble a high-performance and omnivorous computer. The heat dissipation of the CPU reaches 105 W, and the included Wraith Prism cooler, supplemented by RGB LED lighting, is designed to protect the system from overheating.

Long live the king!
The 3900X processor with 12 cores and 24 threads belongs to the advanced Ryzen 9 Matisse line, in which AMD has embodied its best practices. Besides the fact that this is one of the most powerful processors on the market, it is also attractive because it runs on a regular AM4 socket, like most other AMD chips. Recall that the record-breaking powerful AMD "stones" of the past generation belonged to the Threadripper family and worked with expensive and rare motherboards based on TR4 logic.
Old logic in a new way
Together with the new Zen 2 microarchitecture, AMD presented a new topology. Processors are no longer a monolithic crystal, but are assembled from several components. This allows the company to offer new powerful chips with 12 and 16 cores within the old Socket AM4 ecosystem. Each such chipset combines two CCX-complexes containing four cores and 16 MB of L3 cache. Given that the Ryzen 9 3900X is a twelve-core processor, it is constructed from three semiconductor crystals at once. All this, instead of using the Zen 2 architecture, allowed AMD to make the processor omnivorous and almost universally high-performance: it performs well under almost any kind of load. Detailed application testing has shown that AMD's new mainstream flagship is much faster than the slightly cheaper eight-core i9-9900K and, moreover, often outperforms even the 12-core Core i9-9920X, the official price of which is $1,200, but for which in stores from — for the deficit ask for much more.
Not for enthusiasts
Now for the disadvantages. AMD was in a hurry with the release of this processor and literally rewrote drivers, changed overclocking-power consumption ratios and updated firmware for socket AM4 literally on the go. All this resulted in a strange situation that, being an enthusiast processor, the 3900X began to behave strangely as soon as you climbed under the hood: either the arithmetic performance between cores changed, or it simply did not respond to changes in BIOS frequencies or voltage increases. As a result, it turned out that its stable frequencies are 4.7 – 4.8 GHz. Powerfully and stably, only memory overclocking is kept here. It turns out that out of the box the processor works like clockwork, just turn on XMP and you're good to go. For overclocking, you need to either wait for a stable firmware, or wait until the Ryzen 9 3950X goes on the market.
