Gcc vs msvc performance. When comparing GCC vs Microsoft Visual C++, the Slant community recommends Microsoft Visual C++ for most people. In the question “What are the easiest to use C++ compilers and IDEs?” Jan 30, 2024 · I want to know if there is any benefit in using MSVC over GCC on Windows? Like more compatibility or integration or something? There is also an intel compiler, what about that? It seems like MSVC has been far quicker to support new c++20/23 constructs than GCC or Clang (at least in terms of library features). Slowest is mingw on windows via autotools (>30m). MSVC ), MSVC does vectorize, but doesn't do as good a job as clang. clangcl vs msvc was not much difference (less than 30s diff). Jul 20, 2020 · With AVX2 available for your planar version ( - vs. 3.

Jan 30, 2021 · What could be the reason for this major performance difference? MSVC: ~36 seconds GCC: ~1:10 minutes The libraries I'm linking against are: Boost Catch2 Loguru CLI11 I suspect that MSVC might use precompiled headers to gain such a speed boost or maybe vcpkg can install precompiled headers for libraries too? When comparing GCC vs Microsoft Visual C++, the Slant community recommends Microsoft Visual C++ for most people. The sheer amount of additional In general they produce binaries of more or less comparable performance. Fastest is msvc natively via cmake (3m). In the question “What are the easiest to use C++ compilers and IDEs?” Nov 7, 2011 · GCC is a fine compiler, and can produce code that has pretty much the same performance, if not better, than MSVC. Enough so that performance-minded projects usually wouldn't consider MinGW/GCC for Windows code. if you turn off the virus scanner and inherited filesystem permissions. libc, which determine the "env" or "abi" part of the target triple). It is missing some low-level Windows-specific features though. And windows environment is not very friendly for gcc based toolchain that spawns a lot of processes. Jan 16, 2014 · I'm seeing a big difference in performance between code compiled in MSVC (on Windows) and GCC (on Linux) for an Ivy Bridge system. MSVC using 32x32=>32-bit multiplies that run as 2 uops on Intel. . 25107. The code does dense matrix multiplication. =P Context: This will take a minute, so bear with me. As of 2025, the MSVC compiler is included in Visual Studio 2022. MSVC vs Clang++ Performance - has anyone tested recently on a large project? Question: Has anyone done recent performance comparisons between MSVC and Clang++? Ideally on a large project? More ideally on a professional 3D game project, but that's being greedy. Let's see who is really better by testing common errors in Clang 6. It might still be acceptable for many use-cases, but notice that clang uses 1-uop on 32-bit integers that were zero-extended from 8-bit, vs. linux builds are from 3m (cmake) to 8m (autotools). clangcl on WSL it would be much faster, but msvc natively would beat it, esp. Clang first dissed GCC in their “Expressive Diagnostics” article. Aug 19, 2021 · Top C++ compilers for hosted environments 1. 0. Why?

But implementation of c++11 synchronization primitives in mingw, at least up to not so distant past, was much much worse than in msvc (2015). It seems like MSVC has been far quicker to support new c++20/23 constructs than GCC or Clang (at least in terms of library features). 0, and, via the Compiler Explorer, MSVC 2017 19.

Nov 14, 2024 · the difference is not in the C compilers per se (clang vs gcc), it is the C runtimes (a. a. on Windows, we have -msvc vs -gnu (vs -gnullvm); on Linux, we have mainly -gnu vs -musl, (there are many other environments too, mostly for specific hardware or embedded systems, such VC++ generates significantly better code than GCC.
