Whether you're a competitive gamer, a PC builder, or just want to ensure your equipment is running at peak performance, using the right testing tools is essential. In 2025, a variety of powerful and user-friendly websites are available to diagnose issues, benchmark performance, and calibrate your hardware. This guide explores the best hardware testing sites, from comprehensive system benchmark tools to specialized peripheral testers.
When you need to measure the raw power of your PC's core components—like the CPU, GPU, and RAM—these tools provide in-depth performance metrics.
3DMark One of the most recognized names in gaming benchmarks, 3DMark offers a suite of tests to measure gaming performance5. Its primary tests, such as Time Spy for DirectX 12 and Port Royal for ray tracing, provide scores that you can compare against a massive database of other users' results. This helps you understand how your rig stacks up and is invaluable for overclocking and stability testing5.
Geekbench A versatile benchmarking application, Geekbench measures your CPU and GPU performance using tests relevant to modern applications, including machine learning and augmented reality5. Its key advantage is its cross-platform capability, allowing you to compare performance data between Windows, macOS, Linux, and even mobile devices like iPhones and Androids5.
HWMonitor & HWiNFO These tools excel at real-time hardware monitoring. HWMonitor provides a clear interface to track your system's voltages, temperatures, power consumption, and fan speeds, which is crucial for diagnosing overheating issues5. HWiNFO offers even more in-depth hardware analysis, with frequent updates to support the latest technologies and standards, all while ensuring no personal data is collected7.
Peripherals are your direct connection to the game. Ensuring they are responsive and accurate is critical for a good experience.
ControllerTest.org This free, browser-based tool is a one-stop shop for testing any modern gamepad1. It provides a detailed, real-time analysis of every component of your controller. You can test buttons, analog sticks, triggers, and D-pads, with precise data on input latency, press count, and pressure sensitivity1.
Its standout features include:
Vibration Test: Allows you to test the intensity and patterns of your controller's vibration motors1.
Calibration Tool: Helps fix common issues like stick drift for PS5, Xbox, and other controllers, improving precision and extending the controller's life1.
Broad Compatibility: Works instantly with PlayStation (PS5/PS4), Xbox (including Elite), SCUF, and generic USB or Bluetooth PC gamepads with no software installation required1.
Performance Benchmarks: The site provides benchmarks for input latency and button response time, so you can see how your gamepad compares to others1.
For developers and QA professionals, ensuring a web application runs smoothly across all hardware configurations is vital.
Selenium As one of the most popular open-source web testing tools, Selenium allows you to automate tests across various browsers and operating systems, including Windows, macOS, and Linux36. It supports multiple programming languages, making it a flexible choice for development teams3.
Playwright Developed by Microsoft, Playwright is an open-source framework for automating website testing across Chromium, Firefox, and WebKit3. It's known for its detailed debugging capabilities, providing logs, screenshots, and video recordings to help identify issues quickly3.
LambdaTest This is a cloud-based platform that allows you to perform automated cross-browser testing on over 2,000 real browsers, devices, and operating systems6. It is ideal for ensuring your web application provides a consistent experience for all users, regardless of their hardware6.
