Refurbished 12-core Zen 5 desktop processor

The AMD Ryzen 9 9900X is a refurbished desktop processor built on the Zen 5 architecture. It delivers 12 cores and 24 threads with a 4.4 GHz base frequency and up to 5.6 GHz max boost. The chip includes integrated Radeon graphics and fits the Socket AM5 platform.

Suits builders needing high thread counts on AM5

This processor suits users who want 24 threads for rendering, compilation or heavy multitasking on a modern AM5 motherboard. It supports DDR5-5600 memory in dual-channel mode up to 192 GB and offers 24 usable PCIe 5.0 lanes. Buyers who require a bundled cooler or a lower thermal design power should evaluate alternatives.

120 W thermal design power guides cooling choice

The 120 W TDP is the key specification that determines the cooling solution and power delivery required. No cooler is included in the box, so a compatible aftermarket cooler rated for at least 120 W is mandatory. Motherboard VRM quality and case airflow must match this heat output for stable operation.

Questions about this item

Does the processor come with a cooler or do I need to buy one separately?

The Ryzen 9 9900X is sold as a processor only; no cooling device is included, so a compatible AM5 cooler must be purchased separately.

Which DDR5 speed does the 9900X officially support and what is the maximum memory capacity?

The CPU officially supports DDR5-5600 in dual-channel mode and can address up to 192 GB of system memory.

What does the 5.6 GHz max boost frequency mean for everyday workloads?

The 5.6 GHz max boost is the highest single-core frequency the processor can reach under load; sustained all-core speeds will be lower and depend on cooling and motherboard power delivery.
