Nvidia 900-21001-0020-000 A100 80GB HBM2 PCI-E GPU Tensor Ampere Computing Accelerator Card

Unleashing the Power of and Computing

The 900-21001-0020-000 Nvidia A100 80GB PCIe Tensor Core GPU represents a monumental leap in accelerated computing, designed to meet the unprecedented demands of modern data centers, research institutions, and enterprises pushing the boundaries of artificial intelligence and scientific discovery. Building upon the revolutionary Ampere architecture, this accelerator card is engineered to tackle the most complex computational challenges, from training massive AI models to running intricate simulations and powering data analytics at an immense scale.

Nvidia Ampere Architecture

The heart of the A100 80GB is the Nvidia Ampere architecture, a ground-breaking design that delivers the greatest generational performance leap in the company's history. This architecture introduces several key innovations that redefine the capabilities of a data center GPU.

Multi-Instance GPU (MIG) Technology

One of the most transformative features of the A100 is its Multi-Instance GPU (MIG) capability. This technology allows a single physical A100 GPU to be partitioned into as many as seven secure, isolated GPU instances. This is a game-changer for cloud service providers and data centers, enabling optimal GPU utilization by serving multiple users or workloads simultaneously on a single card. Each MIG instance has its own high-bandwidth memory, cache, and compute cores, ensuring quality of service and fault isolation.

Memory with 80GB of HBM2e

The "900-21001-0020-000" variant of the A100 is equipped with a massive 80GB of high-bandwidth HBM2e memory. This is a critical differentiator for workloads that are constrained by memory capacity or bandwidth.

Memory Bottlenecks

Large-scale AI models, such as those for natural language processing (e.g., GPT-3, BERT) and recommendation systems, have parameter counts that run into the billions. The A100's 80GB frame buffer allows these entire models to be loaded into the memory of a single GPU, avoiding the complexity and communication overhead of multi-GPU configurations for model parallelism. This dramatically simplifies software development and accelerates time-to-solution. Paired with this immense capacity is a staggering over 2 terabytes per second (TB/s) of memory bandwidth. This ensures that the powerful Tensor and CUDA Cores are constantly fed with data, preventing them from sitting idle. For data-intensive tasks like seismic processing, genomic sequencing, and financial modeling, this bandwidth is essential for maintaining peak computational throughput.

PCIe Form Factor 

The Nvidia A100 80GB PCIe card is designed for broad compatibility and ease of integration into existing data center infrastructure. Unlike the SXM4 form factor designed for Nvidia own HGX systems, the PCIe version can be deployed in standard, off-the-shelf servers from a wide range of OEMs and ODMs.

Flexible

This flexibility allows organizations to scale their and HPC infrastructure incrementally. A single A100 PCIe card can be added to a server to accelerate a specific application, or multiple cards can be linked together using Nvidia NVLink to create a powerful, cohesive compute node for the most demanding workloads.

Inference

For inference, 900-21001-0020-000 the A100 delivers unparalleled throughput and latency. Features like structured sparsity, support for INT8 and INT4 precision, and the MIG technology make it possible to serve thousands of AI-based recommendations, translations, or image analyses per second from a single GPU.

Drug Discovery and Genomics

The A100 accelerates molecular dynamics simulations for protein folding and virtual screening of drug compounds, as well as the analysis of massive genomic datasets, paving the way for personalized medicine. The ability to process and analyze terabytes of data in-memory enables real-time business intelligence. The A100 can accelerate platforms like Apache Spark, allowing data analysts to query and visualize complex datasets interactively, uncovering insights that were previously hidden by long processing times.

Secure Multi-Tenancy with MIG

As previously mentioned, MIG technology is not just about utilization; it's a core security feature. By providing hardware-level isolation, it ensures that workloads from different users or departments cannot interfere with or access each other's data. This is a fundamental requirement for public cloud providers and enterprises with strict data governance policies.

Advanced Diagnostics and Reliability

The A100 includes enhanced features for in-field diagnostics and reliability. This includes advanced ECC (900-21001-0020-000) protection for both HBM2e memory and the L1/L2 caches to ensure data integrity, which is paramount for long-running scientific simulations and mission-critical AI services.

Nvidia Enterprise

This is an end-to-end, cloud-native suite of AI and data analytics software that is certified to run on the A100. It includes frameworks like Tensor Flow, PyTorch, and RAPIDS, providing businesses with a supported, scalable, and secure platform for production AI.

Nvidia HPC SDK

For HPC developers, the HPC Software Development Kit provides compilers (for C++, C, and Fortran), libraries, and tools to maximize performance on the A100 GPU. It enables developers to easily GPU-accelerate their existing applications or build new ones from the ground up.

The Definitive Accelerator for the Exascale 

The Nvidia A100 80GB PCIe GPU (900-21001-0020-000) is more than just a component; it is a complete computing platform. By combining the transformative Ampere architecture with a massive 80GB HBM2e memory subsystem and versatile PCIe form factor, it delivers unmatched performance for AI, data analytics, and HPC. Its innovative features like MIG and third-generation Tensor Cores address not only the need for speed but also the critical requirements of utilization, security, and scalability in the modern data center. For any organization looking to lead in the age of AI and accelerated computing, the A100 80GB is the foundational technology to build upon.
