About the ASRock Rack 4U8GPU-EPYC/2T
The ASRock Rack 4U8GPU-EPYC/2T is a purpose-built 4U GPU server chassis supporting eight full-height, full-length, double-slot GPU accelerators connected via PCIe 4.0 with optional NVLink bridge accessories for NVIDIA SXM and PCIe NVLink configurations. The 4U form factor provides superior thermal management over 1U and 2U GPU designs, enabling sustained 300-400W TDP operation per GPU slot across the full 8-GPU array — critical for extended training runs where GPU throttling would degrade training iteration time and model convergence.
The system is built on the AMD EPYC 7003 (Milan) SP3 single-socket platform, providing 128 PCIe 4.0 lanes that are distributed to all eight GPU slots via a dual-tier PCIe 4.0 switch topology, ensuring each GPU maintains 16 lanes of Gen4 bandwidth to the switch fabric. A high-bandwidth NVMe RAID array of four U.2 Gen4 drives provides local training dataset scratch storage, while dual 100GbE HDR InfiniBand (optional) or 25GbE Ethernet connects nodes in multi-node training clusters.
The 4U8GPU-EPYC/2T is ASRock's flagship enterprise AI training platform and competes directly with Dell EMC PowerEdge XE8545 and HPE Apollo 6500 in the GPU server segment. Its availability as a barebone allows/ODM integrators to configure GPU, storage, and memory to customer specifications, making it the highest-volume professional GPU server SKU in ASRock's catalog.
Ideal for
- Large-scale deep learning model training (GPT, diffusion models, transformers)
- Enterprise private AI cloud GPU pool nodes for multi-tenant training workloads
- HPC scientific simulations requiring sustained multi-GPU floating point throughput
- Genomics and drug discovery requiring large-scale parallel GPU compute
- Autonomous vehicle simulation and sensor fusion model training
- National laboratory and academic research HPC cluster GPU nodes
