Radiance PC CoreIA 128 Dual 5090

Radiance PC CoreIA 128 Dual 5090

The Radiance PC CoreIA 128 Rack 2×5090 is a 4U rack-mountable workstation designed for the most demanding professional workloads in local AI, GPU computing, rendering, and production. Designed for rack integration (studio, business, lab), it combines high computing density with a stable and scalable platform.

At the heart of the system, the Ryzen 9 9950X3D provides excellent CPU power and high responsiveness for multitasking, data preparation, and heavy workflows. For acceleration, the presence of two NVIDIA GeForce RTX 5090 32 GB offers massive GPU capacity, ideal for advanced inference, simultaneous execution of multiple models, multi-GPU pipelines, and compute-intensive workloads.

With 128 GB of DDR5 memory, fast NVMe storage, and a 2000 W Platinum power supply, this configuration aims for stability under continuous load and reliability in a professional environment. The SilverStone SST-RM42-502 4U chassis facilitates rack deployment while maintaining convenient accessibility for maintenance.

Like all Radiance Systems PCs, this model is fully configurable (memory, storage, GPU, OS, etc.) to precisely adapt the machine to your use: AI, creation, computing, virtualization, or production.

Workstation configurator: what options to choose?

By default, all our configurations are already optimized for computation and local artificial intelligence.

All available options are compatible with each other, tested, and assembled by our technicians so that your workstation is delivered ready to use.

Collapsible content

1. Case

Role: ensure efficient airflow, maintain stable temperatures over time, and protect components.

Key takeaways:

A well-ventilated case improves stability for long workloads (computation, inference, data processing) and reduces noise. More compact form factors require stricter thermal management.

The case also influences the overall aesthetics of the machine.

2. Processor

Role: Manage overall system responsiveness, multitasking, data preparation, and certain computation tasks.

Key takeaway:

The higher the number of cores, the more comfortable the system is with:

  • running multiple applications simultaneously,
  • preparing data for AI,
  • compiling, encoding, or processing CPU loads.

3. Processor Cooling

Role: maintain consistent performance over time and avoid any frequency drops related to temperature.

  • Air cooling: reliable, quiet, and durable solution.
  • Water cooling (AIO): better temperatures under continuous load and more compact integration.

Key takeaway: good cooling is essential for the prolonged loads typical of AI.

4. Motherboard

Role: Ensure the compatibility, stability, and scalability of the workstation.

Key takeaway:

More comprehensive motherboards offer:

  • more ports (USB, USB-C),
  • more SSD slots,
  • better power delivery to components,
  • often integrated Wi-Fi and Bluetooth.

This facilitates future upgrades.

5. Random Access Memory (RAM)

Role: Temporarily store data being processed and enable smooth work on large volumes of information.

Key takeaways:

  • 32 GB: Recommended baseline for local AI, development, and inference
  • 64 to 96 GB: High comfort for RAG, computer vision, and more complex projects
  • 128 to 192 GB: Suitable for heavy loads, large datasets, and advanced professional use

High memory capacity allows you to process more data simultaneously and avoid slowdowns during intensive loads.

6. Graphics card (GPU)

Role: Accelerate AI calculations (inference, generation, vision, parallel computing).

Key takeaways:

Video memory (VRAM) is crucial:

  • the higher it is, the more complex models you can run locally,
  • the GPU directly influences AI performance, much more so than the CPU in most cases.

7. M.2 NVMe SSD (main drive)

Role: host the system, applications, and ensure fast data access.

Key takeaways:

  • 1 TB is a recommended minimum,
  • 2 TB or more offer more comfort for projects, models, and datasets.

High speeds primarily improve copying and loading of large files.

8. Second M.2 SSD

Role: Add fast storage dedicated to projects, AI models, or working data.

9. Additional Disk/SSD (SATA)

Role: secondary storage.

  • SATA SSD: silent and responsive for secondary data
  • HDD: large capacity at a lower cost, but slower

10. Power Supply

Role: Provide stable and reliable power to the entire system.

Key takeaways:

The selected power supply is always sufficient for the chosen configuration.

If you are considering future upgrades (more powerful GPU, adding components), it is recommended to anticipate a power margin.

Gold certified power supplies are more efficient, quieter, and more durable.

11. Wi-Fi & Bluetooth

Role: Wireless connectivity for the network and peripherals.

Key takeaways:

A PCIe card is more stable and performs better than a USB dongle.

There's no need to add a solution if the motherboard already has these features.

12. Operating System (Windows)

Role: software work environment.

By default, Windows 11 Professional is installed and activated.

You can also choose:

  • the system language,
  • a dual boot Windows 11 Pro + Ubuntu LTS,
  • Ubuntu
  • or an installation without a system.

Frequently Asked Questions

What is the purpose of a local AI workstation compared to the cloud?

A local AI workstation allows you to run and develop artificial intelligence applications directly on your machine, without relying on external cloud services.

It offers several key advantages: data privacy, total cost control, low latency, and offline operation.

It is an ideal solution for businesses, developers, and professionals who want to keep their data in-house and have a stable and predictable working environment.

Can I train AI models with this PC?


Yes, it is possible to train lightweight AI models or perform fine-tuning on this type of configuration.

The Radiance PC CoreAI 32 is primarily designed for inference, development, and experimentation, rather than for the extensive training of large models.

For intensive training loads or very large models, more powerful configurations or distributed solutions will be more suitable.

What are the delivery times for this PC?

Expect an 8-day preparation period followed by 48 hours for shipping, making a total of 10 business days. Alternatively, you can pick it up directly from our location in Auriol (13) once the PC is ready.

I want to pick up my PC on-site in Auriol (13), how does that work?
