The Bandwidth Breakdown analysis type uses the event-based sampling collection and is targeted for Intel® Core™ 2 processor family. Use this analysis type to understand the contribution of different components of bus transactions (simple reads, reads for ownership, and writes-back) to the code performance.
Port Saturation analysis type uses event-based sampling collection and is targeted for the Intel® microarchitecture code name Sandy Bridge.
This analysis type uses events that help understand how port saturation affects the performance of your application at a per-thread granularity.
Configure the Intel® VTune™ Amplifier to collect special metrics and analyze idle and active power consumption of your system and the impact your software has on the system behavior.
For a custom event-based sampling data collection, set up the Sample After Value (SAV) that is a frequency with which the Intel® VTune™ Amplifier interrupts the processor to collect a sample during hardware event-based data collection. SAV is measured as the number of events it takes to trigger a sample collection.
