How do GPU cloud costs compare between hyperscalers and GPU-specialized providers?

AWS p4d.24xlarge (8x A100) costs ~$32.77/hr on-demand. Google A2 UltraGPU (8x A100) is ~$29.39/hr. CoreWeave H100 instances start at ~$2.49/hr per GPU. Lambda Cloud H100 is ~$2.49/hr per GPU. For sustained training workloads, specialized GPU clouds can reduce costs by 50–70%.

What are the key considerations for multi-GPU distributed training infrastructure?

Distributed training efficiency depends on high-bandwidth GPU interconnects (NVLink, InfiniBand), network fabric (100/400 Gbps Ethernet or RDMA), cluster topology, and deep learning framework support (PyTorch DDP, DeepSpeed, Megatron-LM). H100 NVL and A100 SXM configurations offer 3.2 Tbps NVLink bandwidth.

What GPU cloud solutions are best for inference workloads versus training?

Inference workloads benefit from cost-optimized GPU instances (AWS G5/G6, Azure NCas_T4_v3) using NVIDIA T4 or L4 GPUs. Dedicated inference platforms like AWS Inferentia2, Google Cloud TPU v5e, and Azure Maia 100 offer 3–5x better inference price-performance than general-purpose GPU instances.
