Our take on the AMD Ryzen 9 5900X AM4 Desktop Processor

The AMD Ryzen 9 5900X is a 12-core, 24-thread desktop processor for the AM4 socket, built on Zen 3. It has a 3.7 GHz base clock and boosts up to 4.8 GHz, with 64 MB of L3 cache. It suits gamers and creators who want strong multi-threaded performance without moving to a new platform. Compared with Intel's 12th and 13th Gen chips, it trades some single-thread speed for efficiency and cache, and it needs a graphics card since it has no integrated graphics.
