Specs compared

How we chose these

We pulled every desktop from our catalogue that lists the NVIDIA RTX PRO 4000 GPU, which yielded 4 machines from Adamant Custom. We then compared each on CPU core count, RAM, storage, and the 24GB of VRAM common to all. No unit was tested or measured by us; we rely solely on the specifications provided by the seller and the manufacturer's public pages. Prices shown are live and read from the store listing at the time of viewing, so they may change.

What to look for

CPU: cores and clock speed

All four desktops use AMD Ryzen Threadripper processors, but they differ in core count and frequency. The 64-core 9980X excels at highly parallel workloads like rendering and simulation, but it runs at a lower 3.2GHz base. The 24-core PRO 9965WX has a higher 4.2GHz clock, which can improve single-threaded tasks like some 3D modeling operations. The 32-core 9970X at 4.0GHz sits in between. Choose cores if your software scales well, and clock speed if you rely on faster single-thread performance.

RAM: more is better for professional apps

Memory capacity directly affects how large your projects can be. 128GB is a solid baseline for 4K video editing, complex CAD, or multiple VMs, while 256GB is essential for in-memory databases, large machine learning models, or massive terrains. The 64-core model only has 32GB, which may become a bottleneck if your software needs to hold large datasets. Consider the amount of memory your primary applications require and whether you plan to expand later.

Storage: balance speed and capacity

All these machines come with NVMe SSDs, but capacities range from 1TB to 4TB. For professional work, 4TB is comfortable if you keep large project files locally, whereas 1TB is workable if you rely on external or network storage. If you edit 8K video or store large 3D libraries, lean toward 4TB. If you're mostly running compiled code or smaller assets, 1TB might suffice.

GPU: the RTX PRO 4000

Every pick in this list is built around the NVIDIA RTX PRO 4000, which comes with 24GB of GDDR6 memory. This GPU is designed for professional applications like rendering, AI inference, and CAD. The 24GB frame buffer handles large 4K textures and large neural network models without running out of memory. Since all desktops share this GPU, your choice among them depends on the CPU, RAM, and storage rather than graphics horsepower.

Operating system: Windows 11 Pro

All four desktops come with Windows 11 Pro, which adds features like BitLocker device encryption, group policy management, and Remote Desktop, compared to Windows 11 Home. For professional environments, Pro is usually the right choice because it provides better security and manageability. Check that your favourite applications support Windows 11; the OS meets the minimum requirements of a 64-bit CPU, 4GB RAM, 64GB storage, and TPM 2.0, all of which these systems far exceed.

Expansion and future-proofing

Since these are full tower workstations, they typically have room for additional storage drives and memory modules. The 64-core model's 32GB RAM can be upgraded, and the 1TB storage option likely has spare M.2 slots. Look for models that allow you to add RAM or storage later if you think your needs will grow. If you plan to expand, favor configurations with more free slots, though not all sellers list that detail.

Questions

What is the RTX PRO 4000 GPU good for?

The RTX PRO 4000 is a professional workstation GPU with 24GB of video memory. It's suited for 3D rendering, video editing with large timelines, AI model inference, and scientific visualisation. The 24GB framebuffer lets you work with larger textures and datasets than typical consumer cards, making it a fir for advanced tasks where memory is critical.

Is Windows 11 Pro worth the extra cost?

Windows 11 Pro adds features like BitLocker, Group Policy, and remote desktop that are often essential in business or advanced workstation setups. If you need these enterprise-grade capabilities, Pro is worth it. For casual users, Home might suffice, but all these desktops ship with Pro, so you're already covered.

Do these desktops support ECC memory?

The 24-core and 64-core models are described with 'ECC' in the name, indicating they include error-correcting memory that is important for long-running, data-sensitive computations. The 32-core models do not mention ECC in the listing, so we cannot confirm whether they use ECC RAM. If data integrity is critical, choose an ECC-equipped model.

Can I upgrade the RAM on the 64-core model later?

Technically, most Threadripper platforms support additional memory, so upgrading is possible. However, the 64-core model comes with only 32GB, and you would need to purchase and install new DIMMs. Since we haven't physically inspected the machine, we recommend checking with the seller for available memory slots and maximum supported capacity before buying.

How does the RTX PRO 4000 compare to a GeForce RTX card?

RTX PRO GPUs are designed for professional workloads, with certified drivers for applications like CAD and scientific computing, plus potentially better support for ECC memory and larger frame buffers. GeForce cards are aimed at gaming and may not have the same level of certification. The RTX PRO 4000 here offers 24GB VRAM, which is high for a professional card, while a GeForce RTX 5090 has 32GB but is a consumer card.
