Intel C++ compilers:
ICC (Linux), ICL (Windows) are classic Intel C/C++ Compilers. Whereas, ICX is an Intel nextgen compiler based on Clang /LLVM technology along with Intel proprietary optimizations and code generation.
- You may use ICC for performance on CPU targets.
- ICX enables OpenMP TARGET offload to Intel GPU targets.
Intel DPC++ compiler:
DPC++ compiler driver supports single-source cross-architecture compilation that can target CPUs, GPUs, FPGAs, and other accelerators. It is based on Clang/LLVM technology.
In short, if you are looking for performance on CPU targets, ICC/ICPC compiler would be an ideal choice. For OpenMP GPU offload support, you may rely on ICX/ICPX compiler. For single-source heterogenous cross-compilation (that can target CPUs, GPUs, FPGAs, etc), DPC++ is the best choice.

oneAPI DPC++ vs C++ 2021
Hi, I have a question in which cases I should use oneAPI vs. C++ 2010 compiler. I understand that the classical Intel C++ 2021 compiler does not support GPU/FPCA targets, but is it save to say that I oneAPI DPC++ compiler offers everything that the classic
