NVIDIA A40

The World’s Most Powerful Data Center GPU for Visual Computing

The NVIDIA A40 GPU is an evolutionary leap in performance and multi-workload capabilities from the data center, combining best-in-class professional graphics with powerful compute and AI acceleration to meet today’s design, creative, and scientific challenges. Driving the next generation of virtual workstations and server-based workloads, NVIDIA A40 brings state-of-the-art features for ray-traced rendering, simulation, virtual production, and more to professionals anytime, anywhere.

Powered by the NVIDIA Ampere Architecture

NVIDIA Ampere Architecture CUDA® Cores

Double-speed processing for single-precision floating point (FP32) operations and improved power efficiency provide significant performance improvements for graphics and simulation workflows, such as complex 3D computer-aided design (CAD) and computer-aided engineering (CAE).

Second-Generation RT Cores

With up to 2X the throughput over the previous generation and the ability to concurrently run ray tracing with either shading or denoising capabilities, second-generation RT Cores deliver massive speedups for workloads like photorealistic rendering of movie content, architectural design evaluations, and virtual prototyping of product designs. This technology also speeds up the rendering of ray-traced motion blur for faster results with greater visual accuracy.

Third-Generation Tensor Cores

New Tensor Float 32 (TF32) precision provides up to 5X the training throughput over the previous generation to accelerate AI and data science model training without requiring any code changes. Hardware support for structural sparsity doubles the throughput for inferencing. Tensor Cores also bring AI to graphics with capabilities like DLSS, AI denoising, and enhanced editing for select applications.

48GB of GPU Memory

Ultra-fast GDDR6 memory, scalable up to 96GB with NVLink, gives data scientists, engineers, and creative professionals the large memory necessary to work with massive datasets and workloads like data science and simulation.

Third-Generation NVIDIA NVLink®

Connect two A40 GPUs together to scale from 48GB of GPU memory to 96GB. Increased GPU-to-GPU interconnect bandwidth provides a single scalable memory to accelerate graphics and compute workloads and tackle larger datasets. A new, more compact NVLink connector enables functionality in a wider range of servers.

Virtualization-Ready

Next-generation improvements with NVIDIA virtual GPU (vGPU) software allow for larger, more powerful virtual workstation instances for remote users, enabling high-end remote design, AI, and compute workloads.*

PCI Express Gen 4

PCI Express Gen 4 doubles the bandwidth of PCIe Gen 3, improving data-transfer speeds from CPU memory for data-intensive tasks like AI, data science, and 3D design. Faster PCIe performance also accelerates GPU direct memory access (DMA) transfers, providing faster I/O communication of video data between the GPU and GPUDirect® for Video-enabled devices delivering a powerful solution for live broadcast. A40 is backwards compatible with PCI Express Gen 3 for deployment flexibility.

Data Center Efficiency and Security

Featuring a dual-slot, power efficient design, NVIDIA A40 is up to 2X as power efficient as the previous generation and compatible with a wide range of servers from worldwide OEMs. The NVIDIA A40 also includes a CEC 1712 chip that enables secure and measured boot with hardware root of trust, ensuring that firmware has not been tampered with or corrupted.
