Local AI Clustering with Dell's Pro Max GB10: Pairing Two Nvidia Grace Blackwell Systems for Home AI Compute
Tom's Hardware tested a pair of Dell Pro Max with GB10 systems, creating a local AI cluster with 256GB of unified memory using Nvidia's ConnectX 7 200Gbps NICs for RDMA over RoCE. Priced at $6,332 each (with 4TB SSDs), the cluster offers a cheaper, quieter, and more desk-friendly alternative to traditional GPU servers for running large language models that exceed 128GB. The systems feature Nvidia GB10 processors (10x Arm Cortex-X925 + 10x Arm Cortex-A725), Blackwell GPU with 6144 CUDA cores, 128GB LPDDR5X memory, and 280W USB-C power adapters. Dell's version adds a front power LED and improved grille design compared to the reference DGX Spark. The article concludes this is currently the cheapest way to access large local AI models with high-performance networking.
