TL;DR
A selection guide for enterprise GPUs, focusing on memory, interconnect, stability, and sustainable rental capacity.
A800, A100, and H20: selection logic for large-memory training and enterprise inference
Enterprise GPUs are designed for longer jobs, larger models, shared team workloads, and production services that need stable operation. Their value comes from memory capacity, data-center reliability, and the ability to reduce engineering workarounds.
Why it matters
Large memory can save more than it costs when it prevents repeated out-of-memory failures, excessive quantization, complex model splitting, or long debugging cycles. For training and enterprise inference, stability and predictable runtime often matter more than the lowest card price.
How to apply it
For training, compare memory size, memory bandwidth, multi-card communication, storage throughput, and checkpoint behavior. For inference, compare latency, concurrency, cold start time, and monitoring coverage. Use real test traffic before moving business workloads onto a long rental.
Next steps
Run a short validation cycle, record utilization and failure data, and then choose the card that solves the current bottleneck with the lowest total cost. Keep image versions, logs, metrics, and recovery steps documented before scaling the workload.
