Intel® C++ Compiler (ICC)

High-performance compiler for C++ applications on Intel architecture

Last Updated: April 2025 v2025.6.0

The Intel® C++ Compiler is a high-performance compiler for C++ applications that generates native code for Intel-based systems. This compiler leverages hardware capabilities like SIMD instructions, multithreading, and other Intel-specific features to optimize performance on Xeon, Core, and Xeon Phi architectures.

Key Features

Optimized for Intel® Xeon and Core processors
Supports OpenMP, CUDA, and Intel® Threading Building Blocks
Heterogeneous programming support with SYCL
Automatic parallelization and vectorization
C++17, C++20, and C++23 standards support
