A key feature of Intel Advisor is that it offers information to the user via a graphical user interface (GUI) or and Command Lineas well. Here in an example taken from the Intel Website site where we can see an example of vectorization and code insights offered by their applicationthe advisor:

Below are few of the main features of the Intel Advisor:
===Optimize Vectorization for Better Performance===
Vectorization is one of the most important features of the Intel Advisor, it is an operation of Single instruction Multiple Data(SIMD) instructions on multiple data objects in parallel in single core of a CPU. This can very effectively increase performance by reducing loop overhead and making better use of math unit.
• Get actionable user code-centric guidance to improve vectorization efficiency.
===Model, Tune, and Test Multiple Threading Designs===
The Threading Advisor tool is applied to the model and tests the performance of various multi-threading designs such as OpenMP, Threading Building Blocks (TBB), and Microsoft Task Parallel Library (TPL) without limiting the development of the project. The tool achieves this by helping you with prototyping, testing the project's scalability for larger systems, and optimizing faster. It will also help identify issues before implementing parallelization.
The tool is primarily used for adding threading to the C, C++, C#, and Fortran languages.
The analysis gives a realistic visual representation of application performance against hardware-imposed conditions, such as memory bandwidth and computer capacity.

====Roofline Chart Data====
The Roofline chart plots an application's achieved model is a visual performance and arithmetic intensity against the machine's maximum achievable model used to deliver performanceestimations of a given application running on multi-core or many-core.
• Arithmetic intensity (x-axis) - measured in number of floating-point operations (FLOPs) or integer operations (INTOPs) per byte, based on the loop algorithm, and transferred between CPU/VPU and memory
• Performance (y-axis) - measured in billions of floating-point operations per second (GFLOPS) or billions of integer operations per second (GINTOPS)

===Efficiently Offload Your Code to GPUs===
The Offload Advisor is an extended version of the Intel® Advisor, a code modernization, and performance estimation tool that supports OpenCL and SYCL/Data-Parallel C++ languages on CPU and GPU.

===Create, Visualize, and Analyze Task and Dependency Computation Graphs===
Flow Graph Analyzer (FGA) is a rapid visual prototyping environment for applications that can be expressed as flow graphs using Intel Threading Building Blocks (Intel TBB) applications.
• Apart from TBB, it helps visualize DPC++ asynchronous task graphs, provides insights to task scheduling inefficiencies and analyzes open MP task dependencies for better performance
