Navigating the world of GPUs often means choosing between groundbreaking performance and manageable costs. NVIDIA aims to bridge that gap with its latest addition, the L40S GPU. Designed with both powerful AI workloads and intensive graphical tasks in mind, the NVIDIA L40S combines an impressive 48GB of video memory and advanced architecture to deliver exceptional value without sacrificing essential performance. Who Should Consider the L40S The NVIDIA L40S is a versatile GPU based on the Ada Lovelace architecture, delivering impressive performance for both artificial intelligence tasks and visualization solutions like rendering and 3D graphics. Its defining feature is a substantial 48GB of GDDR6 ECC video memory, particularly essential for neural networks. Even mid-sized AI models, consisting of billions of parameters, require significant memory for training and deployment. For larger models exceeding 100 billion parameters, the memory demands grow exponentially. When dealing with substantial language models or generative networks like LLaMA or Stable Diffusion, limited video memory can severely restrict fine-tuning processes and routine tasks. The L40S provides ample memory to comfortably handle large models while remaining within a reasonable budget — especially when compared to top-tier GPUs costing two or three times more but offering comparable memory capacity. Machine Learning and Neural Networks The L40S features 568 fourth-generation Tensor cores, significantly enhancing performance in AI-driven tasks. FP8 computations and mixed-precision support (FP8, FP16) facilitate rapid processing of vast data arrays, directly boosting training and inference speeds. With its ample memory preventing quick saturation, the L40S excels in applications such as computer vision and natural language processing (NLP). Although the H100 remains NVIDIA's flagship, the L40S provides approximately 1.7 times better inference performance than the trusted A100 — a robust GPU solution released in 2020, which still maintains its relevance today. Graphics and Rendering Like many NVIDIA GPUs, the L40S incorporates 142 third-generation RT cores, making it highly suitable for rendering and creating high-quality 3D graphics. If your workflow includes visualization or virtual production alongside neural networks, this GPU seamlessly handles such tasks. Thanks to its 48GB memory and third-generation RT cores, the L40S doubles ray tracing performance compared to the A100, enabling real-time rendering of realistic 3D scenes. Importance of Video Memory Returning to the standout feature — the 48GB of video memory — the amount directly influences how much data you can process per training iteration or inference. Insufficient memory can extend training tasks into weeks. The L40S delivers adequate capacity for effectively training and evaluating medium to large-scale models. This advantage is especially pronounced for generative models like large language models (LLMs) or diffusion models, notorious for their memory demands, particularly when parameters number in the tens of billions. With the L40S, you'll accelerate model training and inference without sacrificing speed due to resource limitations. Practical Testing Results Performance testing of the L40S across various use cases demonstrated compelling results. When running the LLaMA 3.1 70B in INT4 configuration, two L40S GPUs outperformed a single A800, delivering nearly a 1.8-fold increase in processing speed (1,475.08 vs. 852.55 tokens per second over 1,000 prompts). With an expanded dataset of 10,000 prompts, the advantage persisted at 1,556.16 vs. 948.93 tokens per second. The difference was particularly noteworthy during tests with Qwen 2.5 14B. When processing 1,000 prompts, two L40S GPUs achieved 3,943.29 tokens per second, only slightly behind the A800’s 4,003.48 tokens per second. However, under heavier loads of 10,000 prompts, the L40S configuration outperformed the A800, reaching 4,248.22 tokens per second, underscoring its stable scalability. Testing a lighter Qwen 2.5 7B model involved running two instances — one on each of two L40S GPUs versus two instances on an A800. The L40S GPUs delivered a combined throughput of approximately 12,331.42 tokens per second (6,126.35 + 6,205.07), compared to 7,249.81 tokens per second on the A800. Despite slightly trailing, these results highlight the L40S's excellent price-to-performance ratio for medium-scale parallel tasks. Wrapping Up If you require a powerful yet affordable GPU solution for neural networks and visualization tasks, the NVIDIA L40S effectively addresses most of your needs. While its performance doesn't quite reach flagship levels, the 48GB of video memory and robust throughput make it an exceptional choice for AI-related workloads. By 2025, as AI memory requirements continue to grow, the L40S offers sufficient resources to work efficiently without needing costly top-tier solutions like the H100.
