Performance Notes
NVIDIA B200 SXM on Vast.ai unleashes Blackwell's potential, with expectations of 20 petaFLOPS FP4/40 petaFLOPS FP8 for inference/training, leveraging 192GB HBM3e at 8 TB/s bandwidth. Performance varies by host: data center rigs offer 400GbE/NVLink for multi-GPU scaling (up to 8x B200), while others provide 100Gbps Ethernet and NVMe storage (2-30TB). Multi-node distributed training works via NCCL; check host interconnects. Emerging DLPerf benchmarks guide selection, but real-world data is limited post-launch—prioritize verified hosts for consistency. Limitations: consumer setups may cap at PCIe bandwidth or lower uptime; no uniform SLAs like hyperscalers.
