A100 introduces double-precision Tensor Cores, providing the biggest milestone since the introduction of double-precision computing in GPUs for HPC.
This promises to help data centers and cloud providers drive down costs when leasing their computing power to clients. Similarly, Figure 3 shows substantial performance improvements across different HPC applications. It enables multiple GPU Instances to run in parallel on a single, physical A100 GPU. Lambda provides GPU workstations, servers, and cloud
For latest tech news in your inbox, once a day! Data center managers aim to keep resource utilization high, so an ideal data center accelerator doesn’t just go big—it also efficiently accelerates many smaller workloads. Even at its minimum lead, the Ampere A100 delivers a 50% boost over the Volta V100 GPU which is impressive. New warp-level reduction instructions supported by CUDA Cooperative Groups.
Structure is enforced through a new 2:4 sparse matrix definition that allows two non-zero values in every four-entry vector.
INT8 Tensor Core operations with sparsity deliver unprecedented processing power for DL inference, running 20x faster than V100 INT8 operations. The Ampere architecture will first end up in the A100, a graphics card designed for data analytics and scientific computing. The accumulate step will be performed in standard FP32, resulting in an IEEE 754 FP32 tensor output. NVIDIA also shows how the performance of their GPU accelerators has improved over time with the latest full-stack innovations for AI. Each L2 partition localizes and caches data for memory accesses from SMs in the GPCs directly connected to the partition.

Each instance’s SMs have separate and isolated paths through the entire memory system – the on-chip crossbar ports, L2 cache banks, memory controllers and DRAM address busses are all assigned uniquely to an individual instance.
Tensor Core acceleration of INT8, INT4, and binary round out support for DL inferencing, with A100 sparse INT8 running 20x faster than V100 INT8. The diversity of compute-intensive applications running in modern cloud data centers has driven the explosion of NVIDIA GPU-accelerated cloud computing.
The A100 Tensor Core GPU includes new technology to improve error/fault attribution, isolation, and containment as described in the in-depth architecture sections later in this post.
The A100 GPU includes 40 GB of fast HBM2 DRAM memory on its SXM4-style circuit board. The A100 Tensor Core GPU includes new Sparse Tensor Core instructions that skip the compute on entries with zero values, resulting in a doubling of the Tensor Core compute throughput.

Task graphs enable a define-once and run-repeatedly execution flow. Each SM in A100 computes a total of 64 FP64 FMA operations/clock (or 128 FP64 operations/clock), which is twice the throughput of Tesla V100. The server is the first generation of the DGX series to use AMD CPUs. With the A100 GPU, NVIDIA introduces fine-grained structured sparsity, a novel approach that doubles compute throughput for deep neural networks.
Sparsity is possible in deep learning because the importance of individual weights evolves during the learning process, and by the end of network training, only a subset of weights have acquired a meaningful purpose in determining the learned output.
CSPs often partition their hardware based on customer usage patterns.
CPU to GPU communication will be twice as fast when compared with previous generations of servers. It interfaces with CUDA-X libraries to accelerate I/O across a broad range of workloads, from AI and data analytics to visualization. Hardware cache-coherence maintains the CUDA programming model across the full GPU, and applications automatically leverage the bandwidth and latency benefits of the new L2 cache. FP64 Tensor Core operations deliver unprecedented double-precision processing power for HPC, running 2.5x faster than V100 FP64 DFMA operations.

The A100 represents a jump from the TSMC 12nm process node down to the TSMC 7nm process node.
Fabricated on the TSMC 7nm N7 manufacturing process, the NVIDIA Ampere architecture-based GA100 GPU that powers A100 includes 54.2 billion transistors with a die size of 826 mm2. We're now accepting pre-orders for our Hyperplane A100 GPU server. Expect Nvidia to talk more about Ampere in the coming months as the company prepares to release its rumored 3000-series RTX graphics cards for consumers. 1.24x = 18.1 TFLOPS (est.
Microsoft will be the first customer to adopt the A100 card, and plans on using the technology in the company’s cloud computing platform, Azure, which data scientists can use to fine-tune and run their AI programs. The new Multi-Instance GPU (MIG) feature allows the A100 Tensor Core GPU to be securely partitioned into as many as seven separate GPU Instances for CUDA applications, providing multiple users with separate GPU resources to accelerate their applications. To optimize capacity utilization, the NVIDIA Ampere architecture provides L2 cache residency controls for you to manage data to keep or evict from the cache.
In terms of specifications, the A100 PCIe GPU accelerator doesn't change much in terms of core configuration. With MIG, each instance’s processors have separate and isolated paths through the entire memory system. The DGX A100 offers far superior node-to-node communication bandwidth when compared with the DGX-1 or the Lambda Hyperplane-8 V100. Keep an eye on your inbox!
The main difference can be seen in the TDP which is rated at 250W for the PCIe variant whereas the standard variant comes with a 400W TDP. The A100 GPU includes several other new and improved hardware features that enhance application performance. Using public images and specifications from NVIDIA's A100 GPU announcement and a knowledge of optimal silicon die layout, we were able to calculate the approximate die dimensions of the new A100 chip: We then lay a prototype die of (25.589 mm x 32.259 mm) across the known usable area of a 300mm silicon wafer.
