Benchmarks & Throughput

Multi-GPU Scalability

Scaling Efficiency

Single GPUThe RTX PRO 6000 Blackwell Server Edition PCIe Gen 5 offers high single GPU efficiency with PCIe Gen 5 providing up to 64GB/s bandwidth.
2-GPUScaling between two GPUs is limited by PCIe lane contention, but can achieve reasonable performance with direct PCIe communication.
4-GPUFour GPU scaling is constrained by PCIe bandwidth, with diminishing returns due to increased contention and lack of NVLink.
8-GPUScaling to eight GPUs is significantly limited by PCIe bandwidth, leading to sub-linear scaling due to contention and absence of NVLink.
64+ GPUAt 64+ GPUs, InfiniBand or Ethernet overhead becomes significant, requiring careful network topology design to mitigate latency and bandwidth issues.

Scaling Characteristics

Cross-Node LatencyCross-node latency is minimized with GPUDirect RDMA support, allowing for efficient data transfer across nodes using InfiniBand or RoCE v2.
Network BottlenecksThe primary bottleneck is the Host-to-Device bridge due to PCIe limitations and lack of NVLink, which affects data transfer rates and latency.
ParallelismSupports Data, Model, Pipeline, and Tensor Parallelism, compatible with frameworks like DeepSpeed and Megatron for distributed training.
