Latest trends in GPU technology

Perugia - March 9th, 2025


The latest trends in GPU technology for fluid simulation highlight significant advancements in performance, scalability, and cost efficiency.

GPU Acceleration in Computational Fluid Dynamics (CFD)
GPUs are now an essential tool in CFD, drastically reducing simulation times. Tasks that once took an entire day on CPU servers can now be completed in just over an hour using multiple high-performance GPUs. This acceleration benefits industries such as aerospace, automotive, and pharmaceuticals, where fluid dynamics simulations play a critical role in research and development.

Scalability and Multi-GPU Configurations
Multi-GPU setups are becoming more prevalent, offering improved computational power and efficiency. FluidX3D, for example, has demonstrated a system combining Intel and NVIDIA GPUs to maximize performance while keeping costs lower than high-end single-GPU solutions. The ability to integrate GPUs from different vendors allows for more flexible and cost-effective simulation environments.

Optimized GPU Selection for Specific Workloads
Choosing the right GPU depends on the simulation requirements. Consumer-grade GPUs like the RTX 4090 are excellent for single-precision workloads, providing high performance at a lower cost. On the other hand, enterprise GPUs such as the NVIDIA H100 and A100 excel in handling double-precision and memory-intensive tasks, making them more suitable for large-scale and highly detailed simulations.

Cloud and Hybrid Deployments
Many CFD software providers, including industry leaders like Ansys and Siemens, are optimizing their tools for GPU acceleration in both on-premise and cloud-based environments. Cloud solutions powered by high-performance GPUs enable scalable, on-demand simulations, reducing infrastructure costs and increasing accessibility for researchers and engineers.

Expansion of Competition in High-Performance CFD
AMD is making strides in the high-performance computing space with its Instinct MI300X GPU, which is specifically designed to handle computationally heavy simulations. This competition provides more options for researchers and engineers, challenging NVIDIA’s dominance in the field and fostering further innovation.

Overall, GPUs are transforming fluid simulation by making it faster, more efficient, and more scalable. With continued advancements in hardware and software optimization, the future of CFD looks increasingly driven by high-performance GPU computing.
