Interesting results. I'm not a big fan of Spec; too many compilers focus specifically on getting good spec numbers at the expense of other tests, just like video card manufacturers focus on getting Doom 3 running fast while failing to perform well on other applications. That said, I know that ICC consistently produces fast code for computationally bound applications, on the Pentium 4 at least. This includes real-world applications like video codecs, where ICC often produces code that is 10-15% faster. The paper I'm working on takes a slightly different view of floating point, and will include some "different" benchmarks. ..Scott
