AMD uProf offers:
- Performance Analysis
- CPU Profiling – to identify runtime performance bottlenecks of the application.
- System Analysis
- Performance Counter Monitor utility – to monitor system performance metrics
- Power Profiling
- System-wide Power Profiling – to monitor thermal and power characteristics of the system.
- Energy Analysis
- Power Application Analysis – to identify energy hotspots in the application (Windows only).
AMD uProf can effectively be used to:
- Analyze the performance of one or more processes or the entire system
- Track down the performance bottlenecks (hotspots & micro-architecture) in the source code
- Identify ways to optimize the source code for better performance and power efficiency
- Examine the behavior of kernel, drivers, and system modules
- Analyze Thread concurrency
- Observe frequency, thermal and power characteristics (Power profiling)
- Observe system metrics like IPC, Core effective frequency, memory bandwidth, etc.

Performance Analysis
AMD uProf profiler follows a statistical sampling-based approach to collect profile data to identify the performance bottlenecks in the application. The profile data collection can be triggered by – OS timer, core PMC events and IBS. AMD uProf offers user friendly UI to view and analyze the profile data thereby helps to optimize wide variety of applications, drivers, game engines etc.
