The AMD Ryzen 7 5800X is a desktop processor with 8 cores, launched in November 2020. It is part of the Ryzen 7 lineup, using the Zen 3 (Vermeer) architecture with Socket AM4. Thanks to AMD Simultaneous Multithreading (SMT) the core-count is effectively doubled, to 16 threads. Ryzen 7 5800X has 32MB of L3 cache and operates at 3.8 GHz by default, but can boost up to 4.7 GHz, depending on the workload. AMD is making the Ryzen 7 5800X on a 7 nm production node, the transistor count is unknown. The silicon die of the chip is not fabricated at AMD, but at the foundry of TSMC. You may freely adjust the unlocked multiplier on Ryzen 7 5800X, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.
With a TDP of 105 W, the Ryzen 7 5800X consumes a good deal of power, so decent cooling is needed. AMD's processor supports DDR4 memory with adual-channel interface. The highest officially supported memory speed is 3200 MHz, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the system, Ryzen 7 5800X uses a PCI-Express Gen 4 connection. This processor does not have integrated graphics, you will need a separate graphics card.
Hardware virtualization is available on the Ryzen 7 5800X, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) can run on this processor, boosting performance for calculation-heavy applications. Besides AVX, AMD is including the newer AVX2 standard, too, but not AVX-512.
