It addresses challenges in design, creativity, and science, leading the evolution of virtual workstations and server workloads. With cutting-edge features for tasks like ray-traced rendering and simulation, it empowers professionals with state-of-the-art capabilities for work anytime, anywhere. 

The Power of NVIDIA Ampere Architecture

Products based on the NVIDIA Ampere architecture deliver notable improvements in performance, features, and benefits compared to previous-generation offerings, including: 

• NVIDIA Ampere Architecture CUDA Cores: Enhanced power efficiency and double-speed processing in single-precision floating-point (FP32) operations lead to substantial performance advancements in graphics and simulation workflows. This is particularly beneficial for intricate tasks like 3D computer-aided design (CAD) and computer-aided engineering (CAE). 
• Second-Gen RT Cores: Featuring up to twice the throughput compared to the prior generation, second-generation RT cores enable simultaneous execution of ray tracing alongside shading or denoising. This results in significant performance boosts for tasks such as photorealistic rendering in film or television production, architectural design assessments, and virtual prototyping of product designs. Additionally, this technology accelerates the rendering of ray-traced motion blur, delivering faster results with enhanced visual precision. 
• Third-Gen Tensor Cores: The introduction of Tensor Float 32 (TF32) precision brings about a remarkable up to 5x increase in training throughput compared to the prior generation, expediting AI and data science model training without necessitating any code modifications. With hardware support for structural sparsity, there is an extraordinary up to 10x throughput enhancement for inferencing. Additionally, Tensor Cores play a pivotal role in accelerating AI-enhanced graphics capabilities, including DLSS (Deep Learning Super Sampling), AI denoising, and advanced editing features in selected applications. 
• 48GB GPU Memory: Equipped with ultra-fast GDDR6 memory, expandable to 96GB through NVLink, the A40 offers data scientists, engineers, and creative professionals the extensive memory needed for tasks involving massive datasets, such as ultra-high-resolution rendering, data science, and simulations.
• Third-Gen NVIDIA NVLink: Link two A40 GPUs to scale from 48GB to 96GB of GPU memory. The increased GPU-to-GPU interconnect bandwidth of up to 112.5GB/s establishes a unified and scalable memory, enhancing graphics and compute workloads while handling larger datasets. The new compact NVLink connector allows deployment in a broader range of servers.
• Virtualization-Ready: Enhanced with next-gen NVIDIA vGPU software, including the NVIDIA Virtual Workstation, the A40 supports larger and more powerful virtual workstation instances for remote users, facilitating high-end remote design, AI, and compute workloads.
• PCI Express Gen 4: With PCIe Gen 4, the A40 doubles the bandwidth of PCIe Gen 3, boosting data-transfer speeds for CPU memory-intensive tasks like AI, data science, and 3D design. This faster PCIe performance also accelerates GPU Direct Memory Access (DMA) transfers, ensuring swift I/O communication of video data between the GPU and GPUDirect for Video-enabled devices - a robust solution for live broadcast. The A40 remains backward compatible with PCIe Express Gen 3 for deployment flexibility.
• Data Center Efficiency and Security: Featuring a dual-slot, power-efficient design, the NVIDIA A40 is up to 2x as power-efficient as the previous generation, validated with a wide range of NVIDIA-certified systems from PNY-backed systems builders and integrators. Additionally, the NVIDIA A40 provides secure and measured boot with hardware root of trust capability, ensuring firmware integrity by preventing tampering or corruption.
