12-Core Liquid-Cooled Workstation

This desktop pairs a twelve-core AMD Ryzen 9 9900X3D processor with a 240 mm liquid cooler and an Nvidia GeForce RTX 5070 graphics card. Thirty-two gigabytes of DDR5 memory and a four-terabyte NVMe SSD provide capacity for demanding creative and engineering workloads. Windows 11 Pro is pre-installed on the mid-tower chassis.

PCI Express x16 graphics and DDR5 memory limits

The RTX 5070 connects through a single PCI Express x16 slot, so a second discrete card cannot be added. The motherboard offers four DDR5 slots with a maximum supported capacity of 192 GB, leaving room for future upgrades. Builders who need more storage than the single M.2 drive provides must use the internal 3.5-inch or 2.5-inch bays.

Twelve-core CPU with 128 MB L3 cache

The Ryzen 9 9900X3D delivers twelve cores and twenty-four threads with a boost clock up to 5.50 GHz and a large 128 MB L3 cache. This combination determines whether the system suits heavily threaded compile, render or simulation tasks. Buyers who require higher core counts or larger cache should consider alternative configurations.

Questions about this item

Should I pick the 32 GB DDR5 or upgrade to the 192 GB maximum the board supports?

The system ships with 32 GB DDR5 across four slots; the X870 motherboard can accept up to 192 GB if you add more modules later.

What does the Ryzen 9 9900X3D's 5.50 GHz boost mean for actual gaming frame rates?

Twelve cores and 128 MB L3 cache let the CPU hit 5.50 GHz on light threads, keeping high frame rates stable in CPU-bound titles.

Does the PCI Express 4.0 x4 link on the 4 TB Samsung 990 PRO cap real-world transfer speeds?

The drive reaches 7450 MB/s read and 6900 MB/s write, which is the practical ceiling of the PCIe 4.0 x4 interface.
