NVIDIA Ampere architecture CUDA cores

Double-speed processing for single-precision floating-point operations (FP32) and improve energy efficiency provide significant performance improvement for graphics and simulation workflows, such as complex 3D computer-aided design (CAD) and computer-aided engineering (CAE).

Second-generation RT cores

With up to twice the presentation of previous generation and the ability to simultaneously execute ray tracing with shading or stripping capabilities, second-generation RT cores offer tremendous speed for workloads such as photo-realistic film content rendering, architectural design assessments, and virtual prototyping of product design. This technology also accelerates motion blur rendering with ray tracing for faster results and greater visual accuracy.

Third-generation tensioner cores

The new Tensor Float 32 (TF32) precision provides up to 5x the previous generation’s training performance to accelerate AI and data science model training without any code changes. In addition, hardware support for structural scatter doubles performance for the deduction. Voltage cores also bring artificial intelligence to graphics with features like DLSS, AI denoising, and enhanced editing for specific applications.
