Hardware Bottleneck Analysis

Whether NVIDIA L40S is compute-bound (TFLOPS) or memory-bandwidth bound (GB/s) across workloads.

Bottleneck Classification

Severely memory-bandwidth bound โ€” 864 GB/s vs 733 TFLOPS FP8

Recommended Quantization

AWQ / GPTQ / GGUF โ€” INT4 essential for 30B+ models

Best Cluster Topology

PCIe Single Node โ€” no NVLink, 2-4 GPU max

Deep Analysis

L40S Ada Lovelace FP8 Inference vs Training Limitations: The L40S excels at FP8 inference โ€” Ada Lovelace's native FP8 Tensor Core support delivers 733 TFLOPS, making it the most cost-effective FP8 inference GPU below the H100 class. For Llama 8B FP8, the L40S achieves ~65 tok/s at batch=1 with 48 GB VRAM leaving 44 GB for KV-cache. However, the L40S has critical limitations for training: (1) No FP64 support โ€” scientific computing and double-precision gradient accumulation are impossible. (2) No NVLink โ€” multi-GPU training relies on PCIe 4.0 (64 GB/s), limiting tensor parallelism to 2 GPUs as communication overhead becomes significant. (3) 864 GB/s GDDR6 bandwidth is 4x slower than H100's 3.35 TB/s HBM3 โ€” batch inference scales poorly beyond batch=16. The optimal use case: production inference for 7B-30B models where FP8 precision provides the best tokens/dollar ratio. Not suitable for training or fine-tuning.

Frequently Asked Questions

How much does it cost to rent an NVIDIA L40S per hour?โ–พ
The lowest spot rate for NVIDIA L40S is $0.69/hr. On-demand pricing starts at $1.73/hr depending on the provider and region. Reserved commitments can reduce costs by ~15%.
What is the monthly reserved pricing for NVIDIA L40S?โ–พ
Monthly reserved pricing for NVIDIA L40S ranges from $1,059/mo to $1,246/mo depending on commitment level and provider.
Can an NVIDIA L40S run 70B parameter LLMs?โ–พ
NVIDIA L40S with 48GB GDDR6 VRAM cannot run 70B parameter models without significant quantization and CPU offloading. For 70B models, consider H100 SXM5 (80GB) or H200 (141GB).
Is spot pricing reliable for distributed NVIDIA L40S training?โ–พ
Spot pricing offers 30-60% savings but carries preemption risk. For distributed training, implement SIGTERM handlers with S3 checkpointing every 30 minutes. Vast.ai and RunPod provide 30-second eviction warnings. For critical workloads, reserved pricing eliminates preemption entirely.
