AMD CodeAnalyst is a GUI-based code profiler for x86 and x86-64-based machines. CodeAnalyst has similar look and feel on both Linux and Microsoft Windows platforms. CodeAnalyst uses specific hardware profiling techniques which are designed to work with AMD processors, as well as a timer-based profiling technique which does not require specific hardware support; this allows a subset of profiling features to work on non-AMD processors, such as Intel processors. As of Mar-2013, CodeAnalyst has been replaced by AMD CodeXL.
