Description of the processor

The AMD Ryzen 9 3900X is a 12-core processor and uses the new AMD ZEN 2 technology and is manufactured in 7 nm. The processor has 64 MB L3 cache and fits into the AM4 socket from AMD.

Its base clock frequency is 3.80 GHz, but the processor can accelerate one core up to 4.6 GHz. If all 12 cores are loaded, it is still enough for 4.2 GHz. Thanks to the hyperthreading technology, which can address each core of the processor twice per clock, it offers the operating system 24 logical cores.

Like all current AMD ZEN processors, the AMD Ryzen 9 3900X can also be overclocked. Then significantly higher clock rates are possible. For overclocking, however, a sufficiently dimensioned air cooler such as the be quiet! Dark Rock 4 Pro is recommended. An AIO water cooling system such as the CORSAIR Hydro Series H150i is also well suited for this. The AMD Ryzen 9 3900X is classified in the 105 watt TDP class.

The memory controller of the AMD Ryzen 9 3900X has two channels and officially supports RAM up to the DDR4-3200 specification. With a suitable XMP memory profile, however, significantly higher clock rates can also be achieved very easily. The so-called memory timings are particularly important here. These determine in what time (in nanoseconds) the main memory can be read or written.

As one of the very first processors, the AMD Ryzen 9 3900X supports the PCIe 4.0 standard with up to 16 lines. This doubles the maximum speed with which graphics cards and fast SSDs can be connected. This requires at least one mainboard with a Z570 chipset, the older chipsets only support the previous PCIe 3.0 standard.

Modern virtualization functions (AMD-V, SEV) are supported by this processor.
