With all of that said, the point of this exercise was to test for improvements in AMD's most recent architecture after several months of patches to Windows 7 and firmware updates. Unfortunately, in our benchmark suite, which is largely made up of applications that our audience has requested over the past year, the speed-ups we were hoping for were not apparent. Only a single application benefited noticeably as a result of the HPC mode that prevents frequency drops in heavy workloads. Thus, most of the discussion surrounding scheduling optimizations remains theoretical, rather than practical.
