Last Monday, the Portland Group, which has been working on compilers and other tools that have been optimized for AMD64, should have gone gold with PGI Workstation 5.0, which includes those optimizations, but instead announced a delay until on or before July 7.
For its unreleased product, the Portland Group is making performance improvements claims averaging 34% over PGI Workstation 4.1 on several industry standard benchmarks. Now that is a huge hike in performance from just compiler optimizations. The SPEC2000 floating point benchmark shows one Opteron result improving by almost 375%.
