For training 70B+ parameter models, prioritize SXM5 form-factors with NVLink. For real-time inference serving, PCIe GPUs like NVIDIA L40S and RTX 4090 deliver 3x better token throughput per dollar.
Avoid standard Ethernet for distributed multi-node clusters. Ensure providers like CoreWeave, Lambda Labs, or Nebius provide non-blocking Quantum-2 InfiniBand (NDR 400Gbps) for linear AllReduce scaling.
GPU training engines stall when dataset loaders bottleneck on disk. Demand direct local NVMe cache (10,000+ MB/s) paired with parallel network filesystems (Ceph, Lustre, or WekaFS).
Hyperscalers charge up to $90/TB to download trained model checkpoints. Choose providers like Lambda Labs, RunPod, and Hyperstack with unmetered or near-zero data egress fees.
Specialized GPU clouds (neoclouds) are purpose-built for AI compute. They deliver raw bare-metal GPU performance without hypervisor jitter, provide InfiniBand networking by default, and offer on-demand hourly rates that are 40% to 70% cheaper than legacy hyperscalers.
For solo developers and bootstrap startups, RunPod and Vast.ai provide the highest value. Vast.ai offers community spot instances from $0.25/hr for an RTX 4090, while RunPod provides 1-click template pods with persistent storage and zero configuration hassle.
Spot instances can be revoked when another client bids higher or when cluster demand spikes. To avoid losing progress, configure automated checkpointing to external object storage (S3 / Cloudflare R2) every 100–500 training steps.
During distributed backpropagation, GPUs must synchronize billions of parameter gradients via collective operations like AllReduce. Standard Ethernet introduces microsecond latency and packet drops that cause GPUs to idle. NVIDIA Quantum-2 InfiniBand provides 3.2 Tbps sub-microsecond RDMA data transfer, maintaining linear 95%+ scaling efficiency.
