In their own words
Green Curve
Green Curve is a free, open-source utility for adjusting NVIDIA GeForce GPU behavior on Windows and Linux. It can inspect and edit live voltage/frequency curves, core and VRAM offsets, power targets, and fan settings. Supported GeForce architectures run from Pascal through Blackwell, with a best-effort fallback for future architectures. Users can save five profiles, switch them with global hotkeys, or switch automatically based on the foreground application. Fan options include driver auto, fixed speed, and temperature curves with up to eight points. A command-line interface supports hardware probing, profile changes and live-state output in text or JSON. Windows has a native GUI; Linux has a keyboard- and mouse-navigable terminal UI. The application loads NVAPI and NVML from the installed NVIDIA driver rather than bundling proprietary driver binaries. The project states it has no telemetry, analytics, cloud tracking or remote error reporting. Windows x64 and Linux x64 are validated on NVIDIA hardware; ARM64 platforms are compile targets without completed live hardware validation. The project warns that tuning may cause instability or hardware damage.
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.
