CUDA 10 is the most powerful software development platform for building GPU-accelerated applications. It has been built for Turing GPUs and includes performance optimized libraries, a new asynchronous task-graph programming model, enhanced CUDA & graphics API interoperability, and new developer tools. CUDA 10 also provides all the components needed to build applications for NVIDIA's most powerful server platforms for AI and high performance computing (HPC) workloads, both on-prem (DGX-2) and in the cloud (HGX-2).

Key Features


  • New GPU architecture: Build and optimize applications for the next generation of Turing GPUs
  • Tensor Cores
  • NVSwitch Fabric


  • CUDA Graphs: A new asynchronous task-graph programming model which enables more efficient kernel launch and execution
  • CUDA/Graphics Interop: New interoperability between CUDA and graphics APIs, including Vulkan and DX12
  • Warp Matrix


  • nvJPEG: New library for hybrid JPEG processing that provides >2x speedup on single and batched image decoding
  • Performance Optimized Libraries: Strong FFT performance scaling across 16-GPU systems, acceleration of dense linear algebra routines such as Eigensolver and Cholesky factorization, and Turing optimized mixed-precision GEMM performance


  • New Developer Tools: New Nsight product family of tools for tracing, profiling, and debugging of CUDA applications (Nsight Systems and Nsight Compute)

Release Highlights

cuFFT 10.0 - Upto 17TF performance on 16-GPUs 3D 1K FFT

cuBLAS 10.0 - Upto 90TF of GEMM performance

cuSOLVER 10.0 - Upto 4x faster on symmetric eigensolver

All library benchmarks use NVIDIA Tesla V100 (or where specified P100) GPUs and Intel Skylake 6140 Gold 2.3 GHz processors
