NVIDIA A40 - The World’s Most Powerful Data Center GPU for Visual Computing

Posted by PNY Pro on Wed, Mar 31, 2021 @ 04:30 PM


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-based products offer significant performance, features, and benefits advantages over prior generation offerings including:

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 shading or denoising, second-generation RT cores deliver massive speedups for workloads like photorealistic rendering of movie or television 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 provides up to 10x throughput for inferencing. Tensor Cores also accelerate AI augmented graphics capabilities like DLSS (Deep learning Super Sampling), AI denoising, and enhanced editing for select applications.

48 GB of GPU Memory

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

Third-Generation NVIDIA NVLink

Connect two A40 GPUs together to scale from 48 GB of GPU memory to 96 GB. Increased GPU-to-GPU interconnect bandwidth (up to 112.5 GB/s) provides a single scalable memory to accelerate graphics and compute workloads and tackle larger datasets. A new, more compact NVLink connector enables deployment in a wider range of servers.

Virtualization Ready

Next generation improvements with NVIDIA virtual GPU (vGPU) software, such as the NVIDIA Virtual Workstation,  allows 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 PCIe 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 that is validated with a wide range of NVIDIA-certified systems from PNY backed systems builders and integrators. The NVIDIA A40 also provides secure and measured boot with hardware root of trust capability, ensuring that firmware has not been tampered with or corrupted.
