When sourcing Nvidia GPUs, you must verify the Architecture (e.g., Ada Lovelace, Ampere, or Hopper) to ensure it meets your performance needs. Key metrics include CUDA Core count, Tensor Cores for AI workloads, and RT Cores for ray tracing. For data center or AI applications (like the H100 or A100 series), pay close attention to HBM (High Bandwidth Memory) capacity and TDP (Thermal Design Power) to ensure your cooling infrastructure is compatible. Always request the exact Part Number (MPN) to avoid receiving lower-spec consumer variants instead of enterprise-grade chips.
