Overview

The 4 GPU RTX 5090 server puts four GeForce RTX 5090 cards, 128 GB of GDDR7 in total, into a 4U air cooled chassis on a single or dual socket AMD EPYC 9005 or Intel Xeon 6 host. It is the lowest cost per GPU in our catalog for inference, fine tuning of small and mid size models, image and video generation, rendering farms and development clusters.

Each card has 21,760 CUDA cores, fifth generation Tensor cores with FP4 support and 1.8 TB/s of memory bandwidth, so one node serves four independent replicas of a model up to the 30B class at FP4, or one larger model split across the cards over PCIe. Hardware AV1 encode and decode on every GPU suits media generation pipelines. There is no NVLink and no ECC on the GPU memory.

GeForce cards are consumer products: NVIDIA does not license the GeForce driver for data center deployment, and the GPU memory is not ECC protected. The server suits buyers who accept those terms for a lab, an office server room or a development cluster, and we ask you to confirm the intended use on the quotation. For ECC, MIG and professional drivers, the 4 GPU 4U PCIe server with RTX PRO 6000 Blackwell Server Edition is the step up.

Use cases

  • Low cost inference
  • Fine tuning small and mid size models
  • Image and video generation
  • Render farms
  • Development clusters
