What Is the Main Difference Between NVIDIA H200 and NVIDIA L40S?

H200 and L40S serve different parts of the data-center GPU market. H200 is a Hopper accelerator built around 141 GB HBM3e and 4.8 TB/s bandwidth. L40S is an Ada Lovelace PCIe GPU with 48 GB GDDR6 and 864 GB/s.

H200 supports NVLink and MIG, which matter for scale-up and multi-tenant compute. L40S does not support either, but it adds RTX-class RT Cores and media engines that H200 is not designed to replace.

For large AI models and HPC, H200 is the stronger choice. For inference combined with visualization, rendering or video, L40S can be more practical.

Memory Capacity and Bandwidth

These specifications affect model fit, KV-cache headroom, batch size and memory-bound workloads.

H200 vs L40S for LLM Inference

H200 offers nearly three times the memory capacity and more than five times the listed memory bandwidth. L40S is still a strong FP8 inference GPU for models that fit inside 48 GB.

H200 vs L40S for Training and HPC

H200 is designed for large training and HPC, with HBM3e, NVLink and MIG. L40S can handle AI training at smaller scale, but its PCIe-only topology and GDDR6 memory system make it a different class of accelerator.

H200 vs L40S for Graphics and Media

L40S has the advantage when the same GPU must support rendering, visualization or media. It includes third-generation RT Cores and multiple NVENC/NVDEC engines. H200 is optimized around compute, AI and HPC.

Final Decision

Should You Choose NVIDIA H200 or NVIDIA L40S?

Choose NVIDIA H200 if:

  • You need 141 GB HBM3e or very high bandwidth.
  • You are training large models.
  • You need NVLink or MIG.
  • HPC or large-scale LLM serving is the primary workload.

Choose NVIDIA L40S if:

  • 48 GB is enough.
  • You need RTX rendering or visualization.
  • Video encode/decode is part of the workload.
  • A 350 W PCIe deployment better fits your infrastructure.

H200 vs L40S FAQs

Common questions about choosing between these NVIDIA GPUs.

Which is better, NVIDIA H200 or L40S?
Choose H200 for very large LLM inference, training, HPC and high-bandwidth multi-GPU workloads. Choose L40S for 48 GB inference, RTX graphics, rendering and media pipelines where a PCIe GPU with lower power is the better operational fit.
What is the main difference between H200 and L40S?
H200 uses Hopper with 141 GB HBM3e and 4.8 TB/s memory bandwidth, while L40S uses Ada Lovelace with 48 GB GDDR6 ECC and 864 GB/s. Tensor Core generation, precision support, interconnects and power can also differ.
Is H200 or L40S better for LLM inference?
H200 offers nearly three times the memory capacity and more than five times the listed memory bandwidth. L40S is still a strong FP8 inference GPU for models that fit inside 48 GB.
Which GPU is better for AI training, H200 or L40S?
H200 is designed for large training and HPC, with HBM3e, NVLink and MIG. L40S can handle AI training at smaller scale, but its PCIe-only topology and GDDR6 memory system make it a different class of accelerator.
How much memory do H200 and L40S have?
NVIDIA H200 provides 141 GB HBM3e, while NVIDIA L40S provides 48 GB GDDR6 ECC. Memory capacity alone does not determine performance, so bandwidth, precision support and workload behavior should also be considered.
Which is cheaper to rent, H200 or L40S?
Cloud rental pricing for H200 and L40S varies by provider, region, configuration and billing model. Check current provider pricing rather than assuming one GPU is always cheaper.
