AMD Ryzen 9 9900X3D

AMD Ryzen 9 9900X3D overview

The Ryzen 9 9900X3D is a 12-core, 24-thread Zen 5 AM5 desktop processor with second-generation AMD 3D V-Cache. This is an official-source product record, not a BYT01 hands-on review; no independent performance, temperature, power or noise measurements are claimed.

Cores, clocks and cache

AMD specifies a 4.4 GHz base clock, boost up to 5.5 GHz, 960 KB L1, 12 MB L2 and 128 MB L3 cache. Maximum boost is conditional rather than a guaranteed sustained frequency.

Platform and memory

The processor uses AM5 and supports PCIe 5.0 with 28 native and 24 usable lanes. AMD lists A620, X670E, X670, B650E, B650, X870E, X870, B840 and B850 chipsets subject to motherboard BIOS support. It supports two DDR5 channels, up to 256 GB UDIMM and DDR5-5600 with two modules.

Power and graphics

Default TDP is 120 W, Tjmax is 95°C and no cooler is included; AMD recommends liquid cooling. Integrated Radeon Graphics has two cores at a published 2200 MHz.

Identity and buying checks

Boxed ID is 100-100001368WOF and tray ID is 100-000001368. AMD lists launch on March 12, 2025 and global availability. Match the exact SKU, BIOS, cooling and seller warranty before purchase.

Evidence limit: this is a product record, not a hands-on review or numeric rating. Future measurements must disclose the sample source, method, conditions and repeatable results.

Same-category records to compare

These records share a category; this alone does not establish suitability for your needs or budget. Compare intended use, configuration and upgrade limits before choosing. Prices, when shown, are dated snapshots, not current offers or stock confirmation. A price difference is not a performance or value verdict.
