In their own words
Intel VTune Profiler
Intel VTune Profiler analyzes application and system performance to help locate bottlenecks in AI, HPC, cloud, IoT, media and storage workloads. It profiles CPUs, GPUs and NPUs, including through a unified XPU Offload Analysis view. Hotspot analysis finds time-consuming code, and Flame Graphs display hot code paths. Microarchitecture exploration identifies hardware performance issues, while memory analysis can reveal cache misses and bandwidth problems. Intel lists support for SYCL, C, C++, C#, Fortran, OpenCL, Python, Go, Java, .NET and Assembly, including mixed-language applications. The profiler is available as a standalone download or through the Intel oneAPI Toolkit, with integrations documented for Microsoft Visual Studio and Eclipse. The 2026.4 release is listed for 64-bit Windows and Linux hosts. Its Linux-only AI Assistant can run collections, report analyses and suggest bottleneck optimizations using the user’s own LLM access; Intel cautions that suggestions may be inaccurate. Some analyses need administrator or root privileges. The tool is free to download and use for commercial and non-commercial purposes.
