Define "recent".

In general, the choice of compiler is unimportant for the performance of
most user-bound programs. I doubt KDE would run much faster if compiled
with ICC, for example.
However, for codecs, image processing, and other math-intensive
operations, Intel generally produces faster code, though
not always. This isn't just a matter of floating-point generation --
Intel's vectorizer gives their compiler a distinct advantage over GCC,
although I expect GCC to catch up in this regard.
Rather than speculate about Apple, it would be better to find more
funding for GCC development. I know that some people are working on this.
