NVIDIA® A40 is the world’s most powerful GPU for visual computing from the data center for today’s design, creative, and scientific challenges (When it is launched). Built on NVIDIA’s Ampere architecture, the A40 combines the latest generation RT Cores, Tensor Cores, and CUDA® cores with 48GB of GPU memory for unprecedented graphics, compute, and AI performance.


NVIDIA A40 Architectural Innovations

CUDA Cores: The NVIDIA Ampere architecture-based GPU CUDA cores bring up to 2X the single-precision floating point (FP32) throughput compared to the previous generation, providing significant performance improvements for graphics workflows such as 3D model development and compute for workloads such as desktop simulation for computer-aided engineering (CAE).

RT Cores: Second-generation RT Cores provide up to 2X the throughput of the first generation, and the ability to concurrently run ray tracing with other graphics or compute tasks such as pixel shading or denoising. This significantly accelerates renders for workflows such as M&E content creation, AEC design evaluations, and manufacturing virtual prototyping. The addition of hardware accelerated Motion BVH (bounding volume hierarchy) improves motion blur rendering performance compared to the previous generation.

Tensor Cores: Third-generation Tensor Cores provide up to 5X the training throughput of the previous generation. The new Tensor Float 32 (TF32) precision accelerates AI calculations with zero code changes, significantly reducing the time required for AI model training. Hardware support for structural sparsity provides up to 10x higher throughput by reducing network model size and speeding up model execution. The latest generation of Tensor Cores also support the brain floating-point format (BFloat16).

Encode/decode engines: The A40 includes one video encode engine and two decode engines, including support for AV1 decode. The A40 delivers the performance required for multi-stream video workloads such as security and video serving.

PCIe Gen 4: The A40 supports PCI Express Gen 4 (PCIe Gen 4), which doubles the bandwidth of PCIe Gen 3 from 15.75 gigabytes per second (GB/sec) to 31.5 GB/sec for x16 connection, improving data transfer speeds from CPU memory for data-intensive tasks such as AI, data science, and creating 3D models from large datasets. Faster PCIe performance also accelerates GPU direct memory access (DMA) transfers, providing faster video data transfers from GPUDirect® for Video-enabled devices and faster input/output (I/O) with GPUDirect Storage.

Motion BVH (bounding volume hierarchy): Hardware-accelerated rendering of motion blur—a common cinematic effect that is difficult to render—means artists no longer need to rely on traditional methods of using motion vectors to achieve motion blur. Motion vectors give the artist flexibility to adjust motion blur in post but require visual fixes for reflections and translucency.

Display support: Using the available display ports, A40 can be used to power large display walls for use cases like virtual production, broadcast, and localized entertainment. A single A40 features three DisplayPort 1.4a connectors and the ability to drive a maximum of up to four 5K (5120 x 2880) at 60 Hz displays. Display support also includes the ability to drive two 8K displays. A40 supports DisplayPort 1.4a, which enables a single cable to drive an 8K display at 60Hz using Display Stream Compression (DSC)
