Dual RTX 5090 Threadripper Pro Workstation

Dual RTX 5090 Threadripper Pro Workstation – Built in the UK

The Dual RTX 5090 Threadripper Pro Workstation is a high-end dual-GPU workstation for AI and machine learning, GPU rendering, simulation and demanding content creation.

The Dual RTX 5090 Threadripper Pro Workstation is built for professionals who need flagship GPU compute, plenty of PCIe expansion and room to grow. It pairs a 32-core AMD Ryzen Threadripper Pro 5975WX on the proven WRX80 platform with two NVIDIA GeForce RTX 5090 graphics cards, each with 32GB of GDDR7 memory. Using DDR4 memory on WRX80 rather than a newer DDR5 platform keeps the cost sensible for workloads where the GPUs do most of the work, such as AI, GPU compute, simulation and rendering. It is built to order, so you can change parts in the configurator to suit your workload.

The Dual RTX 5090 Threadripper Pro Workstation is built on an AMD Ryzen Threadripper Pro 5975WX with 32 cores and 64 threads, fitted to an ASRock WRX80D8-2T motherboard. It has two NVIDIA RTX 5090 graphics cards with 32GB of GDDR7 each, 64GB of DDR4 3200MHz memory and a 1TB WD Black SN7100 PCIe 4.0 NVMe SSD. An Arctic Freezer 4U-M air cooler cools the processor, an FSP Cannon Pro 2000W 80 Plus Gold power supply feeds the system, and everything sits in a Phanteks ENTHOO PRO 2 full tower. It comes with genuine, pre-installed Windows 11 Professional and a 3-year parts and labour warranty.

Threadripper Pro 5975WX processor

The AMD Ryzen Threadripper Pro 5975WX has 32 cores and 64 threads, with a 3.6GHz base clock, a 4.5GHz maximum turbo and 128MB of L3 cache. In a GPU-led workstation it handles data preparation, scene setup, simulation and the host side of AI pipelines, and the thread count gives you headroom to run several virtual machines alongside your main work. It uses the sWRX8 socket and has no integrated graphics, so a dedicated graphics card is required and every monitor connects to the graphics cards. An Arctic Freezer 4U-M 350W server-class air cooler looks after the processor.

Dual RTX 5090 graphics for AI and rendering

Two NVIDIA RTX 5090 cards give this workstation 64GB of GDDR7 in total, 32GB on each card, with 21760 cores and a 575W rating per card. That capacity suits machine learning, LLM inference, GPU rendering, scientific computation and simulation. You can run separate jobs on each card, or split a single job across both in software that supports multiple GPUs. The second card is liquid cooled (AIO), and pairing it with an air-cooled first card helps stop two physically large cards restricting each other’s airflow, which supports stable clocks under sustained load. The graphics card provides 3 x DisplayPort 2.1b and 1 x HDMI 2.1b outputs, for up to 4 monitors (layout may vary by card brand).

64GB DDR4 memory and NVMe storage

The workstation has 64GB of DDR4 3200MHz memory fitted as 4 x 16GB. The ASRock WRX80D8-2T has 8 DIMM slots, with 4 used and 4 free, and supports up to 2TB of memory, so large datasets and scenes have room to grow. The operating system and applications sit on a 1TB WD Black SN7100 M.2 PCIe 4.0 NVMe SSD rated at 7250MB/s read and 6900MB/s write, which gives quick application loading and fast scratch space. A second M.2 PCIe 4.0 x4 slot is free, along with 12 SATA 6Gb/s ports and case mounts for 10 x 3.5in and 11 x 2.5in drives, so dataset and project storage can be added as you need it.

Phanteks ENTHOO PRO 2 case, cooling and power

The Phanteks ENTHOO PRO 2 Black is a full tower with a tempered glass panel, measuring 560mm deep, 240mm wide and 580mm high. It has no fans pre-installed, so this build adds 3 x be quiet! PureWings 2 PWM 140mm black fans for case airflow. The processor is air cooled rather than liquid cooled. An FSP Cannon Pro 2000W 80 Plus Gold fully modular ATX power supply provides the power, leaving headroom for two 575W graphics cards and the rest of the system.

10GbE networking, USB and expansion

Networking is wired only. 2 x 10GbE LAN from an Intel X710-AT2 controller gives fast, stable access to shared storage, render nodes and data servers, and there is no Wi-Fi in this build. The rear panel includes 2 x Type-A 10Gbps ports, and the front panel has 1 x USB 3.2 Gen 2 Type-C, 4 x USB 3.2 Gen 1 Type-A and a headset combo jack. The motherboard’s VGA output is not active because the processor has no integrated graphics. There are five PCIe 4.0 x16 slots, two used by the graphics cards, which leaves three free for storage controllers, networking cards and other add-in cards. The default build has no onboard audio and no sound card, so choose a sound card in the configurator if you need one.

What is the Dual RTX 5090 Threadripper Pro Workstation best for?

The Dual RTX 5090 Threadripper Pro Workstation is primarily a GPU compute machine for AI and machine learning, 3D rendering and scientific simulation, where the two RTX 5090 cards do the heavy lifting. The 32GB on each card suits LLM inference and model work that fits within a single card, while the second card lets you run another job alongside it or use software that spreads work across both. The Threadripper Pro processor and 10GbE networking support the rest of the pipeline, from data preparation to shared storage.

Applications that suit it include Stable Diffusion and ComfyUI for local image generation, Blender for GPU rendering, Unreal Engine 5, DaVinci Resolve and Premiere Pro for high-resolution video work, After Effects for visual effects, Topaz Video AI for AI upscaling and HandBrake for transcoding. Work that depends mainly on CPU speed is a weaker fit, because the platform is built around the graphics cards.

Where does the Dual RTX 5090 Threadripper Pro Workstation sit in the range?

Among its neighbours in the range, this is the system with two graphics cards and the Threadripper Pro platform. The High End Video Editing Computer uses an Intel Core Ultra 7 270K Plus with a single RTX 5070 12GB and 48GB of DDR5 memory, and suits editors who do not need multi-GPU compute. The V-Ray / 3ds Max Workstation – Ryzen 7 9700X / RTX 5070 Ti pairs an 8-core Ryzen 7 9700X with a single RTX 5070 Ti 16GB and 64GB of DDR5 memory, and suits single-GPU rendering. If your AI, rendering or simulation work needs two 32GB cards and the expansion of WRX80, this is the system to choose.

Frequently Asked Questions

What software does the Dual RTX 5090 Threadripper Pro Workstation support?

It is built for GPU-accelerated software, and it runs Windows 11 Professional (genuine, pre-installed). That includes Stable Diffusion and ComfyUI for local image generation, Blender for GPU rendering, Unreal Engine 5, DaVinci Resolve, Premiere Pro, After Effects, Topaz Video AI and HandBrake. The two 32GB RTX 5090 cards and 32 processor cores give large scenes, AI models and video projects plenty of capacity.

Is the Dual RTX 5090 Threadripper Pro Workstation good for AI and LLM work?

Yes, it is designed for machine learning, LLM inference and GPU-accelerated data processing. Each RTX 5090 has 32GB of GDDR7, 64GB across the two cards, so you can run separate jobs on each card or split work across both in software that supports multiple GPUs. The WRX80 platform has five PCIe 4.0 x16 slots, so storage and network cards can be added later.

Why does this workstation use DDR4 instead of DDR5?

For most GPU-accelerated workloads the memory on the graphics cards does the heavy lifting, so system memory speed matters less than GPU capacity. DDR4 on the WRX80 platform keeps the overall cost lower than a DDR5-based alternative. The ASRock WRX80D8-2T supports up to 2TB across 8 DIMM slots when you need more for memory-intensive jobs.

Can I add more memory, storage or cards to it later?

Yes. The build has 4 free DIMM slots, one free M.2 PCIe 4.0 x4 slot, 12 free SATA 6Gb/s ports and 3 free PCIe 4.0 x16 slots. The case has mounts for 10 x 3.5in and 11 x 2.5in drives. If you want a larger configuration, call 0151 317 9860 to discuss it with our team.

Who is this PC best suited for?

It is best suited to AI researchers, machine learning developers, 3D and visual effects studios and simulation professionals who need two flagship GPUs in one machine. It also suits anyone who runs several virtual machines or wants fast wired networking to shared storage and render nodes. It is not aimed at buyers whose software uses the CPU alone.

Is it suitable for CPU-only workloads?

This system is optimised for GPU-accelerated work. The Threadripper Pro 5975WX still has 32 cores and 64 threads, but if your applications are mainly CPU-bound, a newer TRX50 or WRX90 platform may suit you better. Our team can advise on the best configuration for your software.
