Intel® oneAPI DPC++/C++ Compiler

A Standards-Based, Cross-Architecture Compiler

Cross-Architecture Compiling

  • Development Productivity: Targets CPUs and accelerators through single-source code while permitting custom tuning
  • Language Standards Support: Is built to the latest standards, including C++ 17 and SYCL†, and initial support for C++ 20, to ensure portability and support of features like generic lambda expressions and variable templates
  • Industry Standards Support: Supports a subset of OpenMP* 4.5 and 5.0 for GPU offload†
  • Trusted Technology: Leverages well-proven LLVM compiler technology as well as Intel’s history of compiler leadership

†Available in Intel oneAPI DPC++/C++ Compiler only.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
