NVIDIA Ampere Architecture

NVIDIA A800 40GB Active is one of the world's most powerful data center GPUs for AI, data analytics, and high-performance computing (HPC) applications. Building upon the major SM enhancements from the Turing GPU, the NVIDIA Ampere architecture enhances tensor matrix operations and concurrent executions of FP32 and INT32 operations.

More Efficient CUDA Cores

The NVIDIA Ampere architecture's CUDA® cores bring up to 2.5x the single-precision floating point (FP32) throughput compared to the previous generation, providing significant performance improvements for any class or algorithm, or application that can benefit from embarrassingly parallel acceleration techniques.

Third-Generation Tensor Cores

Purpose-built for deep learning matrix arithmetic at the heart of neural network training and inferencing functions, the NVIDIA A800 40GB Active includes enhanced Tensor Cores that accelerate more datatypes (TF32 and BF16) and includes a new Fine-Grained Structured Sparsity feature that delivers up to 2x throughput for tensor matrix operations compared to the previous generation.

Multi-Instance GPU (MIG): Securely, Isolated Multi-Tenancy

Every AI and HPC application benefits from acceleration, but not all require a full A800 40GB GPU. With Multi-Instance GPU (MIG), a single A800 can be partitioned into up to seven fully isolated instances, each with dedicated memory, cache, and compute. This enables guaranteed performance, efficient GPU utilization, and right-sized acceleration for multiple users and applications.

Ultra-Fast HBM2 Memory

The NVIDIA A800 40GB Active GPU features 40GB of high-speed HBM2 memory with 1,555GB/s bandwidth and a 48MB L2 cache—nearly 7× larger than the previous generation—delivering extreme performance for compute-intensive AI workloads.

PCIe Gen 4

The NVIDIA A800 40GB Active supports PCI Express Gen 4, which provides double the bandwidth of PCIe Gen 3, improving data-transfer speeds from CPU memory for data-intensive tasks like AI and data science.
