The Ryzen 9 9900X3D is a 12-core, 24-thread desktop CPU on the AM5 socket built on Zen 5 with second-generation 3D V-Cache. Its 128 MB of L3 cache and 5.5 GHz boost make it a strong pick for gaming and streaming at high frame rates while still handling creation work. It is unlocked for overclocking and supports EXPO memory tuning and Precision Boost Overdrive. Unlike the 16-core Ryzen 9 9950X3D, it trades two cores for lower power draw and heat, and it ships without a cooler, so plan on a strong liquid or air cooler.
