Best GPU Servers for Deep Learning: Deep Learning Server Requirements

Here are the core components of an effective deep learning training server:

GPUs (Deep Learning Accelerators)

NVIDIA H100 & H200: The H200 offers up to 4.8 TB/s bandwidth and outperforms H100 by up to 45% in LLM benchmarks.
NVIDIA GH200 Grace Hopper: Combines Arm CPU and H100-class GPU in one module, excellent for memory-bound or large parallel workloads.
AMD MI250 & MI300: With up to 180 GB HBM2e, MI250 is a solid alternative to H100/H200 for large AI training.

CPU & Memory

Dual-socket AMD EPYC (Genoa/Bergamo) or Intel Xeon (Emerald Rapids).
32–192 cores and up to 4 TB RAM, depending on tier.
High memory bandwidth and PCIe Gen5 lanes are key.

Interconnects

NVLink 4.0 and NVSwitch for intra-server GPU-to-GPU bandwidth.
InfiniBand NDR (400 Gb/s) or HDR (200 Gb/s) for multi-node clusters.

Storage & I/O

PCIe Gen4/Gen5 NVMe SSDs – 8 to 24 bays common.
Storage speed is essential for feeding large model datasets.

Power & Cooling

High-end GPUs draw 400–700 W each.
Enterprise servers use dual 3 kW PSUs and liquid/advanced air cooling.
