Built for modelling and AI workloads

This desktop workstation combines a 12-core AMD Ryzen 9 9900X3D processor with an Nvidia GeForce RTX 5090 graphics card. It ships with 192GB of DDR5 memory and a 2TB Samsung 990 PRO NVMe SSD. Windows 11 Pro is pre-installed on a liquid-cooled platform designed for rendering, video editing and machine-learning tasks.

PCI Express x16 and DDR5 ceiling

The graphics card occupies a single PCI Express x16 slot on the PRIME X870-P motherboard. System memory is capped at 192GB across four DDR5 slots, all of which are populated in this configuration. No additional DIMMs can be added without removing existing modules, and the board provides four M.2 connectors for further NVMe expansion.

192GB DDR5 decides fit

The 192GB memory capacity is the defining specification for buyers who need large datasets resident in RAM. Workloads that exceed this limit will require a different platform. Buyers who need less memory or a smaller form factor should look elsewhere.

Questions about this item

Should I pick the 192 GB DDR5 option or is there a smaller capacity that still hits the 128 MB L3 cache ceiling?

The board tops out at 192 GB across four slots and the Ryzen 9 9900X3D carries 128 MB L3 cache regardless of memory size, so the full kit is the only way to reach the platform maximum.

What does the 4.4 GHz base clock actually deliver once the CPU is under a sustained modelling load?

With the 240 mm liquid cooler the 12-core chip can boost up to 5.50 GHz, so heavy rendering threads run well above the 4.4 GHz floor while staying within thermal limits.

The GPU uses a PCI Express x16 slot — what bandwidth ceiling does that impose on the RTX 5090 32 GB?

The slot provides a full x16 electrical link, so the RTX 5090 32 GB operates at its native interface speed without any lane-width bottleneck.
