A 16-core AMD Ryzen 9 9950X desktop with an Nvidia RTX A4000 16GB GPU, 32GB DDR5 memory, 4TB NVMe SSD and 10TB HDD in a liquid-cooled mid-tower running Windows 11 Pro
This workstation pairs a sixteen-core Ryzen 9 9950X processor with an Nvidia RTX A4000 graphics card carrying 16GB of VRAM. It targets engineers and designers running SolidWorks, CAD, CAM and CAE modelling tasks that benefit from high core counts and certified professional drivers. The system ships with Windows 11 Pro and 32GB of DDR5 memory.
Four memory slots support a maximum of 192GB of DDR5, so the fitted 32GB can be expanded when datasets grow. The 4TB NVMe drive handles active projects while the 10TB hard drive provides bulk capacity for archives and less-frequently accessed files. Both drives connect through standard SATA and PCIe interfaces on the X870 motherboard.
The Ryzen 9 9950X delivers 16 cores and 32 threads with a boost clock up to 5.70GHz and 64MB of L3 cache. That core count is the specification that determines whether this machine matches a workload; buyers who need more threads or a different socket must look elsewhere.
Measured against everything we stock in Gaming PCs, at today’s prices. Recalculated every night.
New to this? Buying a gaming PC with crypto — what to check, what it costs to pay, and what is never asked for.

Use the 4TB Samsung 990 PRO NVMe drive for active projects and the operating system; its sequential reads reach 7450 MB/s and writes 6900 MB/s. The 10TB HDD with 256MB cache is better suited for bulk archives and backups.
The 16-core, 32-thread processor boosts up to 5.70 GHz with 64 MB L3 cache, cooled by a 360mm liquid cooler, so sustained multi-thread workloads such as rendering or simulation stay at high frequencies without throttling.
The Samsung 990 PRO connects via PCIe 4.0 x4, limiting peak throughput to the drive's rated 7450 MB/s read and 6900 MB/s write; the motherboard provides four M.2 connectors, each wired for the same standard.
