Multi-GPU Scalability

Scaling Efficiency

Single GPUThe Instinct MI200 series offers high single GPU efficiency due to its advanced architecture and high memory bandwidth.
2-GPUScaling between two GPUs is efficient, leveraging PCIe Gen4 interconnects with a bandwidth limit of 32GB/s.
4-GPUScaling to four GPUs is feasible but limited by PCIe lane contention and bandwidth, impacting P2P communication.
8-GPUScaling to eight GPUs is constrained by PCIe bandwidth, leading to diminishing returns in performance gains.
64+ GPUAt large scales, InfiniBand or RoCE v2 networking overhead becomes significant, requiring careful tuning to minimize latency.

Scaling Characteristics

Cross-Node LatencyCross-node communication is supported via GPUDirect RDMA, reducing latency and improving throughput for distributed workloads.
Network BottlenecksThe primary bottleneck is the Host-to-Device bridge due to the absence of NVLink, impacting inter-GPU communication.
