Novabench
Novabench is a cross-platform benchmarking and stress testing app that measures CPU, GPU, memory, storage, and network performance on a Mac.
What is Novabench?
Novabench is a desktop benchmarking utility for measuring and comparing computer performance on macOS, Windows, and Linux. It helps users test key hardware areas such as the CPU, GPU, memory, storage, and supported neural processing hardware, then presents the results as easy-to-read scores. Mac users commonly use it to check whether a system is performing as expected after upgrades, troubleshooting, maintenance, or thermal changes. The app also includes network testing, stress testing, and hardware monitoring features that are useful for spotting instability or bottlenecks over time. Because it runs natively on both Apple Silicon and Intel Macs, it fits a wide range of Mac performance-check and diagnostics workflows. Novabench is published by Novabench Inc.
Key features
- Run a full system benchmark across CPU, GPU, memory, and storage
- Measure network quality with download, upload, latency, and jitter tests
- Stress test hardware to check stability under sustained load
- Monitor system sensors such as temperatures, power, and battery health
- Compare benchmark scores with other systems for context
- Track performance over time with historical monitoring features

Safety overview
Status: Safe
Novabench is legitimate benchmarking software, and the hardware access it uses is normal for performance testing and monitoring. During tests, your Mac may run hotter, spin up its fans, and use significant CPU or GPU resources for a short time. That behavior is expected, but you should avoid running heavy benchmarks while doing sensitive work and stop a stress test if your system becomes unstable or unusually hot.
Recommendation: Keep Novabench if you use it to benchmark, compare, or troubleshoot your Mac’s performance. If you no longer run performance tests, you can remove it without affecting normal macOS operation beyond losing its saved results and monitoring features.
