The AMD Ryzen 7 3800X is a desktop processor with 8 cores, launched in July 2019. It is part of the Ryzen 7 lineup, using the Zen 2 (Matisse) architecture with Socket AM4. Thanks to AMD Simultaneous Multithreading (SMT) the core-count is effectively doubled, to 16 threads. Ryzen 7 3800X has 32MB of L3 cache and operates at 3.9 GHz by default, but can boost up to 4.5 GHz, depending on the workload. AMD is building the Ryzen 7 3800X on a 7 nm production process using 3,800 million transistors. 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 3800X, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.
