CZNull

CZNull is a free, browser-based GPU benchmarking platform that performs professional-grade hardware analysis through WebGL-powered tests, delivering instant benchmark scores without any downloads.

What is CZNull?

CZNull is a WebGL 2.0-powered GPU benchmarking tool that runs entirely in the browser. It takes your GPU hardware as input and produces detailed benchmark scores, real-time FPS, frame times, and resource usage metrics as output. The platform works across Windows, macOS, Linux, and mobile devices, and is developed by CZNull.

Key Features

• Advanced GPU Analysis — Multi-dimensional tests covering texture processing, compute shaders, and rendering capabilities, providing comprehensive insights into GPU performance.
• Real-Time Analytics — Live dashboard displaying FPS, frame times, and resource usage during benchmark execution for immediate feedback.
• Cross-Platform Compatibility — Runs on all major operating systems and mobile platforms without any installation or system modifications.
• Adaptive Testing — Intelligent workload scaling automatically adjusts test intensity for accurate results on integrated graphics to flagship GPUs.
• Comprehensive Test Suite — Includes visual rendering benchmarks (3D Volume Rendering, Ray Casting, Dynamic Shadow, Filter Processing) and computational benchmarks (Extreme GPU Load, Parallel Computing, Physics Workload, Mass Particle).
• Secure and Private — 100% browser sandbox execution with no downloads, installations, or data collection, ensuring complete privacy.

Who is it for?

• Gaming enthusiasts — validate system specifications, evaluate hardware upgrades, and optimize game settings by running targeted benchmarks.
• Hardware enthusiasts — compare GPU performance across different systems and track changes over time after driver updates or component changes.
• Software engineers and development teams — test WebGL application performance across diverse hardware configurations and optimize code for consistent user experiences.
• IT professionals — assess hardware capability across an organization without installing software on each machine.

What can you do with CZNull?

• Run a full GPU benchmark suite — Access visual rendering tests like 3D Volume Rendering and Ray Casting, and computational tests like Parallel Computing and Physics Workload, all from your browser.
• Analyze real-time performance metrics — Watch live FPS, frame timing, and resource usage graphs during the benchmark to identify thermal throttling or performance bottlenecks.
• Compare scores across systems — Use normalized benchmark scores to compare GPU capabilities across different hardware, operating systems, and mobile devices, helping decide upgrade timing.
• Validate system stability — Run extreme GPU load tests to stress-check cooling and power delivery under sustained heavy workloads.
