12-Core Ryzen 9 Workstation

This desktop pairs a 12-core AMD Ryzen 9 9900X3D processor with 128GB of DDR5 memory and a GeForce RTX 5070 Ti graphics card. It targets professionals who need strong multi-threaded compute for modelling, rendering and AI workloads alongside high-end gaming performance. Windows 11 Pro is pre-installed on a 4TB NVMe SSD.

PCI Express 4.0 Storage Interface

The Samsung 990 PRO SSD connects through a PCIe 4.0 x4 link, delivering sequential reads up to 7450 MB/s and writes up to 6900 MB/s. That bandwidth ceiling is set by the interface generation, so the drive cannot exceed those speeds even if newer controllers arrive. The motherboard provides four M.2 connectors for future expansion.

128GB DDR5 With 192GB Ceiling

The system ships with 128GB of DDR5 installed across four slots, leaving no free slots for simple additions. The platform supports a maximum of 192GB, so reaching that limit requires replacing all modules with higher-capacity kits. Buyers who anticipate needing more than 192GB of memory should consider a different platform.

Questions about this item

Should I pick the 128 GB DDR5 kit or plan for the 192 GB maximum the board supports?

The system ships with 128 GB DDR5 across four slots. The PRIME X870-P motherboard can take up to 192 GB, so you can add more later if workloads demand it.

What does the Ryzen 9 9900X3D 4.4 GHz base clock deliver once the chip is cooled by the 240 mm liquid cooler?

The 12-core CPU runs at 4.4 GHz base and can boost to 5.50 GHz with 128 MB L3 cache, giving strong multi-thread throughput for modelling, rendering and AI tasks under liquid cooling.

How fast is the 4 TB Samsung 990 PRO over the PCIe 4.0 x4 link on the X870 motherboard?

The drive is rated for up to 7450 MB/sec read and 6900 MB/sec write on the PCIe 4.0 x4 interface, so large project loads and asset streaming stay quick.
