英特尔编译器值得吗？ [英] Are the Intel compilers worth it?

问题描述

直接前进，是英特尔编译器值得吗？我主要是系统级和桌面工作，所以我想我可能benfti。

Prety straight forward, are the Intel compilers worth getting? I do mostly systems level and desktop work so I figure I might benefti. Can anyone with some more experience shed some light?

推荐答案

如果你在Windows上，他们确实提供了一个不错的速度提升比其他英特尔处理器上的编译器。有一个已知的行为，他们选择非英特尔处理器（AMD，VIA）非常慢的代码路径，以及围绕该问题的反垄断探测。

If you are on Windows, they do provide a nice speed boost over other compilers on Intel processors. There is a known behavior where they pick a very slow code path with non-Intel processors (AMD, VIA), and antitrust probes surrounding the issue.

如果使用线程构建块或其他功能，你也有风险绑定你的代码到英特尔编译器长期，因为功能在其他地方不存在。

If you use the thread building blocks or other features, you also risk tying your code to the Intel compiler long term as the functionality doesn't exist elsewhere.

GCC 4.5在Linux上几乎是-par与英特尔编译器。该平台上没有明确的获胜者。

GCC 4.5 on Linux is nearly on-par with the Intel compiler. There is no clear winner on that platform.
