The AMD Ryzen 9 9900X3D pairs 12 Zen 5 cores and 24 threads with stacked 3D V-Cache for strong gaming performance alongside solid content-creation muscle - a step down from the 16-core 9950X3D at a lower price. Base clock is 4.4GHz with boost up to 5.5GHz, and total cache reaches 128MB L3 plus 12MB L2. Runs on AM5 motherboards with integrated Radeon graphics for display-out without a discrete GPU. A 120W part, notably lower power than its 16-core sibling, making cooling requirements more manageable while retaining the gaming benefits of AMD's 3D V-Cache. No cooler included.
