Several lower-end graphics cards and datacenter GPUs are also available including RTX A2000, RTX A4000, A10, and A16. † an additional 2X performance can be achieved via NVIDIA’s new sparsity feature To learn more about these GPUs and to review which are the best options for you, please speak with a GPU expert. Note that these GPUs would not necessarily be connecting directly to a display device, but might be performing remote rendering from a datacenter. The table below summarizes the features of the NVIDIA Ampere GPU Accelerators designed for visualization and ray tracing. † an additional 2X performance can be achieved via NVIDIA’s new sparsity feature Visualization & Ray Tracing GPUs * theoretical peak performance based on GPU boost clock Host-to-GPU transfer bandwidth (bidirectional) GPU-to-GPU transfer bandwidth (bidirectional) NVLink is limited to pairs of directly-linked cards To learn more about these products, or to find out how best to leverage their capabilities, please speak with an HPC/AI expert. Thus, the performance values of the PCI-E A100 GPU are shown as a range and actual performance will vary by workload. For this reason, the PCI-Express GPU is not able to sustain peak performance in the same way as the higher-power part. Note that the PCI-Express version of the NVIDIA A100 GPU features a much lower TDP than the SXM4 version of the A100 GPU (250W vs 400W). The table below summarizes the features of the NVIDIA Ampere GPU Accelerators designed for computation and deep learning/AI/ML. Please contact our team for additional review and discussion. Additional details on each are shared in the tabs below, and the best choice will depend upon your mix of workloads.
