Today, we’re excited to introduce the NVIDIA L40S to our lineup, a powerful contender in the realm of AI and professional workloads. But how does it stack up against the popular RTX 4090? Let’s dive into the comparison.

NVIDIA RTX 4090 vs. L40S: A Detailed Comparison

The NVIDIA RTX 4090 is a powerhouse in the gaming world, renowned for its exceptional performance in rendering and real-time ray tracing. However, when it comes to professional applications, particularly in AI, the L40S brings a unique set of strengths that make it a superior choice for specific workloads. Below is a comparison of the key specifications:

Performance in AI and Deep Learning

1. CUDA and Tensor Cores:
2. • The L40S boasts 18,176 CUDA cores and 568 Tensor Cores, compared to the RTX 4090's 14,592 CUDA cores and 456 Tensor Cores. This makes the L40S significantly more capable in handling complex AI and deep learning tasks, offering up to 24% more FP32 performance.
2. Memory Capacity and Bandwidth:
3. • The L40S is equipped with 48 GB of GDDR6 VRAM, double the 24 GB available in the RTX 4090. This larger memory capacity is crucial for handling larger datasets and more complex models, which is essential for advanced AI research and professional-grade simulations.
   • Although the RTX 4090 has a higher memory bandwidth at 1008 GB/s, the L40S’s 864 GB/s is still substantial for most professional workloads, particularly where higher memory capacity is more beneficial than bandwidth.
3. Energy Efficiency:
4. • The L40S operates at a lower TDP of 300W, compared to the 425W of the RTX 4090. This lower power consumption makes the L40S more suitable for data centers and prolonged operations, where energy efficiency is crucial.
4. Versatility and Application:
5. • The RTX 4090 is primarily designed for gaming and high-end rendering, making it an excellent choice for gamers and creative professionals. However, the L40S is engineered for a broader range of professional tasks, including AI model training, HPC, and complex simulations. Its versatility allows it to handle multi-modal workloads with ease.

The Ideal Choice for AI: L40S

When it comes to AI and professional workloads, the NVIDIA L40S stands out as the superior option. Its combination of high CUDA and Tensor Core counts, large VRAM, and energy efficiency make it the ideal GPU for those working in AI research, 3D rendering, and data-intensive simulations.
