NVIDIA A40 PCIe data center GPU accelerator for Visual Computing

NVIDIA A40 accelerates the most demanding visual computing workloads from the data center, combining cutting-edge NVIDIA Ampere architecture RT Cores, Tensor Cores, and CUDA Cores with 48 GB of graphics memory. This powerful GPU supports everything from virtual workstations accessible from anywhere to dedicated render nodes, bringing next-generation NVIDIA RTX technology to the data center for advanced professional visualization workloads.

TECHNICAL SPECIFICATION

NVIDIA Ampere Architecture CUDA Cores

The NVIDIA A40 features CUDA Cores that double the processing speed for single-precision floating point (FP32) operations while improving power efficiency. This results in significant performance enhancements for graphics and compute workflows, such as complex 3D computer-aided design (CAD) and computer-aided engineering (CAE).

Second-Generation RT Cores

Second-generation RT Cores deliver up to twice the throughput compared to the previous generation, allowing for concurrent ray tracing with shading or denoising capabilities. This results in significant speedups for tasks such as photorealistic movie rendering, architectural design assessments, and virtual prototyping. Moreover, it enhances the rendering of ray-traced motion blur, delivering quicker results with improved visual precision.

Third-Generation Tensor Cores

A40's Tensor Cores offer Tensor Float 32 (TF32) precision, providing up to 5X the training throughput of the previous generation. This accelerates AI and data science model training without any code changes. Hardware support for structural sparsity doubles the throughput for inferencing tasks. Tensor Cores also enhance graphics through deep learning super sampling (DLSS), AI denoising, and advanced editing capabilities in select applications.

48 GB GDDR6 Memory with NVLink

A40  equipped with ultra-fast GDDR6 memory, scalable up to 96 GB with NVLink. This large memory capacity is essential for data scientists, engineers, and creative professionals working with massive datasets and workloads such as data science and simulation.

PCI Express Gen 4

PCI Express Gen 4 doubles the bandwidth of PCIe Gen 3, significantly enhancing data transfer speeds from CPU memory. This improvement benefits data-intensive tasks such as AI, data science, and 3D design. Enhanced PCIe performance also accelerates GPU direct memory access (DMA) transfers, facilitating faster input/output communication of video data between the GPU and GPUDirect for Video-enabled devices, making it a powerful solution for live broadcasts. A40 is also backward compatible with PCI Express Gen 3, providing deployment flexibility.

Data Center Efficiency and Security

With a dual-slot, power-efficient design, the NVIDIA A40 is twice upto as power-efficient as the previous generation and is compatible with a wide range of servers from global OEMs. It includes a secure and measured boot with hardware root-of-trust technology to ensure firmware integrity and security.

NVIDIA A40 GPU empowers advanced visual computing functions such as real-time ray tracing, AI acceleration, and versatile multi-workload support, enhancing the speed of deep learning, data science, and compute-driven tasks. Virtual workstations leveraging the power of the NVIDIA A40, coupled with NVIDIA RTX Virtual Workstation (vWS) and NVIDIA Virtual Compute Server software, undergo rigorous testing across diverse industry applications and professional software, guaranteeing top-notch performance and reliability.
