RTX 5090 AI Workstation
Professional single-GPU AI development, sourced and configured to your specification.
Overview
The RTX 5090 AI Workstation gives individual developers and small teams desktop-class AI compute built around NVIDIA's flagship RTX 5090 and 128GB of ECC memory. Nexus Compute specifies, sources, and configures each unit to your exact software stack so it arrives ready for production work rather than as a box of parts to assemble. The number that decides whether this machine fits your work is VRAM. 32GB holds a 7B to 13B parameter model at BF16 with room left for a working context, or a 30B to 70B model once it has been quantized to 4-bit. Beyond that the weights spill into system memory and generation slows to the speed of the PCIe link rather than the card. If your models already exceed that today, the honest answer is a second GPU, a larger-VRAM professional card, or a rack server. We will tell you that before you buy rather than after. Treat it as a single-user tool: one person training or serving at a time, on a tower that wants a dedicated mains circuit and a location where fan noise under sustained load is not a problem.

Typical Use Cases
- ·Local LLM inference and fine-tuning on mid-scale models
- ·Image and video generation pipelines (Stable Diffusion, FLUX, ComfyUI)
- ·Computer vision model training and dataset preprocessing
- ·Rapid prototyping before scaling to GPU servers or clusters
- ·Retrieval-augmented generation (RAG) development and testing
- ·Quantized inference on mid-to-large open-weight models that fit inside 32GB
- ·LoRA and QLoRA fine-tuning where full-weight training would not fit in VRAM
- ·Local development against a model that will later be served from a GPU server
