The ASRock Rack 1U4G-ROME is a 1U GPU server barebone for AI/ML and HPC deployments, with a single AMD EPYC 7002/7003-capable socket and four full-height, dual-slot PCIe 4.0 x16 expansion positions. It suits data-center teams building compact multi-GPU systems; CPU and memory are not included, and GPUs with top-edge power connectors are unsupported.

Recommended For

  • AI and machine-learning teams deploying several supported PCIe GPUs in a rack, where fitting four dual-slot accelerators into 1U is more important than maximizing performance per GPU.
  • Data-center operators running AI inference or analytics who want multiple GPU workloads and fast local storage in one dense server; ServeTheHome tested four A100 cards and describes GPU partitioning as useful for inference.
  • HPC and technical-computing teams that need an EPYC-based GPU server with PCIe expansion, IPMI remote management, and up to eight E1.S or M.2 storage positions.
  • Server builders with compatible GPUs and rack infrastructure who want to trade a small amount of GPU performance against a more compact four-GPU deployment; ServeTheHome measured slightly lower performance than the comparable 2U system.
