Specs compared

How we chose these

We started with a pool of 20 desktop PCs listed with 48GB of dedicated graphics memory. All picks feature the NVIDIA RTX PRO 5000 GPU, which provides 48GB of VRAM. We shortlisted 10 configurations from Adamant Custom, focusing on different processor choices (AMD Ryzen Threadripper PRO 9985WX, 9975WX, and 9980X) and storage capacities (1TB to 8TB). All units run Windows 11 Pro. Prices shown are live from the store listing and may change. We have not tested any of these units; selections are based on published specifications.

What to look for

CPU: Threadripper PRO vs. Threadripper

The pool includes two families of AMD processors: the Threadripper PRO 9985WX and 9975WX, and the Threadripper 9980X. The PRO series offers higher boost clocks and additional PCIe lanes for more expansion cards. The 9980X is a strong performer but may have slightly lower single-threaded speeds. Choose a PRO chip if you need maximum bandwidth for multiple GPUs or NVMe drives.

System RAM: 512GB across the board

All picks in this list come with 512GB of DDR5 system memory. This is a very high capacity suitable for large in-memory databases, complex simulations, and multi-layer video editing. If your workload does not require this much RAM, these configurations may be overkill, but they ensure you have headroom for the most demanding tasks.

Storage: 1TB to 8TB options

Storage is the main differentiator among these picks. Configurations range from 1TB to 8TB of SSD storage. If you work with large datasets, 8K video files, or multiple virtual machines, opt for 4TB or 8TB. If you use network-attached storage or external drives, a 1TB or 2TB configuration can save money.

GPU: NVIDIA RTX PRO 5000

Every pick features the NVIDIA RTX PRO 5000 GPU with 48GB of VRAM. This is a professional-grade graphics card designed for AI training, 3D rendering, and video processing. It supports NVIDIA CUDA and is certified for many professional applications. For gaming, a GeForce RTX 50-series card may be more suitable, but the RTX PRO 5000 excels in workstation tasks.

Cooling and chassis

All configurations use liquid cooling for the CPU, which helps maintain performance under sustained loads. The chassis is not specified in the listings, so consider the physical size and airflow requirements for your workspace. These are large workstation towers designed for high-power components.

Operating system: Windows 11 Pro

All picks come with Windows 11 Pro. This version includes features like BitLocker encryption, Remote Desktop, and Hyper-V virtualization, which are useful for professional and enterprise environments. Windows 11 Home lacks these features. If you need a different OS, you may need to reinstall.

Questions

What is 48GB of graphics memory used for?

48GB of VRAM is used for large-scale AI model training, rendering complex 3D scenes, 8K video editing, scientific simulations, and running multiple virtual machines with GPU passthrough. It allows you to work with datasets and models that would not fit in the memory of a consumer GPU.

Is the RTX PRO 5000 good for gaming?

The RTX PRO 5000 is a workstation GPU. While it can run games, it is optimized for professional applications and certified for stability in CAD, DCC, and scientific software. For gaming, a GeForce RTX 50-series card with DLSS and higher clock speeds would provide better frame rates at a lower cost.

How much RAM do I need with a 48GB GPU?

All picks in this list include 512GB of system RAM. This is a high amount that complements the 48GB GPU for tasks like loading large datasets into memory. For many AI and video workloads, 128GB or 256GB may be sufficient, but 512GB ensures you have headroom for the most demanding projects.

Can I add more storage later?

Yes, these workstations typically have multiple M.2 and SATA slots for adding more SSDs or hard drives. The exact number of slots is not stated by the seller, but the Threadripper platform supports many PCIe lanes for storage expansion. You can usually add drives yourself.

What is the difference between Threadripper and Threadripper PRO?

Threadripper PRO processors offer more PCIe lanes (128 vs. 80 on standard Threadripper), support for 8-channel memory, and higher boost clocks. They are designed for professional workstations that need maximum bandwidth for multiple GPUs and NVMe drives. Standard Threadripper is still very powerful but has fewer lanes and supports 4-channel memory.
