The AMD Ryzen 9 9900X3D is a desktop processor with 12 cores, launched in January 2025. It is part of the Ryzen 9 lineup, using the Zen 5 (Granite Ridge) architecture with Socket AM5. Thanks to AMD Simultaneous Multithreading (SMT) the core-count is effectively doubled, to 24 threads. Ryzen 9 9900X3D has 128 MB of L3 cache and operates at 4.4 GHz by default, but can boost up to 5.5 GHz, depending on the workload. AMD is building the Ryzen 9 9900X3D on a 4 nm production process using 16,630 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 9 9900X3D, which simplifies overclocking greatly, as you can easily dial in any overclocking frequency.

With a TDP of 120 W, the Ryzen 9 9900X3D consumes a lot of power, so good cooling is definitely needed. AMD's processor supports DDR5 memory with a dual-channel interface. The highest officially supported memory speed is 5600 MT/s, but with overclocking (and the right memory modules) you can go even higher. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the system, Ryzen 9 9900X3D uses a PCI-Express Gen 5 connection. This processor features the Radeon Graphics integrated graphics solution.
