We used to compile 8.0 with icc and 7.x before that. We found very good performance gains for Intel P4 architecture processors and some gains for AMD Athlon. Lately, the gcc compilers have caught up with icc on pipelining optimizations and they generate better code for Opteron than icc, so we found that icc was significantly slower than gcc on Opteron and no different on P4/Xeon. Maybe things have changed in newer versions of icc, the last tests I did were about 1 year ago. - Luke
