Lenovo ThinkSystem GPU Module NVIDIA L40S 48GB PCIe

The Lenovo ThinkSystem GPU Module NVIDIA L40S 48GB PCIe brings the full capability of NVIDIA's Ada Lovelace architecture to validated ThinkSystem server platforms, delivering a purpose-built solution for organizations deploying large-scale generative AI inference, high-performance computing, and professional visualization workloads. Built on the third-generation Ada Lovelace GPU architecture, the L40S integrates 18,176 CUDA cores, 568 fourth-generation Tensor Cores, and 142 RT Cores within a 48GB GDDR6 frame buffer, yielding up to 91.6 TFLOPS of FP32 compute and 733 TOPS of INT8 inferencing throughput. The high-capacity onboard memory, paired with 864 GB/s memory bandwidth, ensures that large language models, diffusion models, and complex simulation workloads remain resident in GPU memory without costly data staging overhead.

Validated as a Lenovo ThinkSystem add-in card, the L40S is fully integrated into Lenovo's system firmware, management tooling, and thermal designs, ensuring predictable performance characteristics in rackmount server environments. The module supports PCIe Gen 4 x16 connectivity and is compatible with multi-GPU configurations via NVLink bridge (where platform topology allows), enabling scaling of AI inference capacity proportionally with deployment needs. Its 300W TDP is managed through active cooling solutions validated by Lenovo engineering, maintaining stability across sustained enterprise workloads.

Launched in Q2 2025, this ThinkSystem-validated module targets enterprises that require a single-slot, PCIe-native accelerator without the overhead of NVSwitch fabric infrastructure, making it particularly attractive for inference-optimized server clusters, virtual workstation infrastructure via NVIDIA vGPU software, and hybrid AI-plus-visualization deployments. The combination of Ada Lovelace Tensor Cores, dedicated AV1 hardware encode/decode engines, and NVIDIA's mature ecosystem of AI frameworks — including TensorRT, Triton Inference Server, and CUDA — positions the L40S as a versatile, production-grade accelerator within Lenovo's enterprise AI portfolio.

Ideal for

• Generative AI inference serving for large language models (LLMs) such as LLaMA, Mistral, and GPT-class architectures requiring large on-device memory footprints up to 48GB per GPU
• Enterprise GPU virtualization using NVIDIA vGPU software to provision multiple concurrent virtual workstation or virtual compute instances from a single physical card
• Scientific computing and HPC simulation workloads including molecular dynamics, computational fluid dynamics, and finite element analysis benefiting from high FP32 and FP64 throughput
• Professional visualization rendering for CAD, digital twins, and media production pipelines where RT Core-accelerated ray tracing and large frame buffers reduce iterative render times
• AI-assisted video transcoding and content processing leveraging dedicated AV1 hardware encode/decode engines in broadcast, media, and streaming infrastructure
• Multi-model AI inference consolidation in data center environments where multiple inference workloads are co-located on ThinkSystem servers to maximize GPU utilization and reduce per-inference operational overhead
