AMD Ryzen 9 9900X 9th Generation Processor ( 4.4 GHz / 12 cores / 24 Threads )

The AMD Ryzen 9 9900X is a high-performance desktop processor built on AMD's Zen 5 architecture, codenamed Granite Ridge, and designed for the AM5 platform. With 12 physical cores and 24 simultaneous threads enabled by Simultaneous Multi-Threading (SMT), this processor is engineered for demanding workloads including content creation, 3D rendering, game streaming, and multitasking-intensive computing. At its heart, the Ryzen 9 9900X runs at a base clock of 4.4 GHz and can reach a maximum boost frequency of up to 5.6 GHz via AMD's Precision Boost 2 technology, which continuously monitors thermals, power draw, and workload characteristics to opportunistically raise clock speeds. Precision Boost Overdrive (PBO) extends this further on compatible motherboards, allowing sustained higher frequencies without manual tuning. Curve Optimizer Voltage Offsets provide per-core fine-tuning for users who want deeper control. Memory support is fully DDR5-native — no DDR4 compatibility — with dual-channel operation supporting up to 192 GB via UDIMM modules. Validated speeds reach DDR5-5600 in a 2-DIMM configuration. AMD EXPO technology enables one-click memory overclocking for compatible kits. Storage connectivity benefits from PCIe 5.0 (28 total lanes, 24 usable), with NVMe support including RAID 0, 1, 5, and 10 configurations. The CPU cores are fabricated on TSMC 4nm FinFET technology, while the I/O die uses TSMC 6nm FinFET, balancing compute density with efficient I/O throughput. Integrated AMD Radeon Graphics (2 compute units at up to 2200 MHz) provide basic display output without a discrete GPU. The processor carries a 120W default TDP and supports a maximum junction temperature of 95°C. No cooling solution is included — a premium aftermarket air cooler or liquid cooler is strongly recommended. Compatible chipsets span AMD's full 600- and 800-series AM5 lineup: A620, B650, B650E, X670, X670E, X870, and X870E. ECC memory is supported subject to motherboard compatibility. The product code is 100-100000662WOF. **Verified Specifications** - Architecture: Zen 5 (Granite Ridge) - Cores / Threads: 12 / 24 - Base Clock: 4.4 GHz | Max Boost: Up to 5.6 GHz - L1 Cache: 960 KB | L2 Cache: 12 MB | L3 Cache: 64 MB - TDP: 120W | Max Temp (Tjmax): 95°C - Socket: AM5 | Memory: DDR5 (up to 192 GB, DDR5-5600 dual-channel) - PCIe Version: PCIe 5.0 (28 lanes total, 24 usable) - CPU Process Node: TSMC 4nm FinFET (cores), TSMC 6nm FinFET (I/O die) - Integrated Graphics: AMD Radeon Graphics (2 CUs, 2200 MHz) - Cooler: Not included - Warranty: 3 Years
