Run a real browser-based graphics benchmark and measure your GPU rendering performance.
This benchmark executes genuine compiled 3D vertex & fragment shaders directly on your graphics hardware. Standard browser security boundaries prevent web applications from querying physical GPU temperatures, fan RPMs, or dedicated VRAM registers. Websites claiming to display live GPU temperature or utilization without desktop companion software are fabricating values.
Select your benchmark preset below and click "Start Benchmark" to run a controlled, repeatable graphics workload.
Every preset enforces a deterministic, reproducible combination of geometry, shaders, and resolution.
Parameters queried directly from your browser's WebGL context. Zero inferred or fabricated values.
Ensure the hero badge indicates "WebGL2 Supported" or "WebGL 1.0 Supported" for hardware acceleration.
Choose from Quick (10s), Balanced (30s), Performance (30s high-load), or Extreme (60s super-sampling).
Modern browsers throttle background tabs to 1 FPS. Keep this window active and focused during testing.
When comparing different hardware or browser versions, always run the same preset under identical resolution settings.
Learn how deterministic 3D workloads exercise graphics pipelines, why warm-up phases matter, and how frame pacing reveals micro-stutter.
A GPU benchmark evaluates graphics rendering performance by submitting a strictly controlled, repeatable workload to your graphics processor. By holding polygon density, vertex matrix transformations, and fragment shader illumination algorithms constant across runs, the benchmark measures raw hardware throughput and frame stability rather than arbitrary variable animations.
A Display FPS test measures your screen refresh rate delivery. A GPU Stress Test applies sustained, indefinite compute stress to evaluate thermal throttling. In contrast, a GPU Benchmark runs a timed, standardized set of presets to calculate comparable performance scores and frame pacing statistics.
In real benchmarking, repeated tests must yield consistent workloads. If objects spawn randomly or particle counts fluctuate unpredictably, performance variation reflects scene changes rather than true GPU capacity. Our benchmark uses deterministic trigonometric orbits and fixed procedural mesh topologies.
When WebGL first renders, the browser compiles GLSL shader source code through the operating system graphics driver (DirectX via ANGLE, Metal, or Vulkan). This compilation frequently introduces a one-time 50–150ms cold-start stutter. Our 2.0-second warm-up absorbs this latency so initial JIT spikes do not corrupt your official minimum FPS or pacing scores.
FPS is simply an average frame count over a one-second window. Frame Time measures the exact millisecond interval required to draw each individual frame. If a system averages 60 FPS but frames fluctuate between 5ms and 30ms, visual motion feels jerky. Frame time tracking reveals true rendering smoothness.
Render Scale modifies internal WebGL framebuffer pixels: Width = round(CSS Width × DPR × Scale). At 150% render scale, the GPU computes shading and rasterization for 2.25x more pixels. This directly stresses your graphics card's pixel fillrate, memory bandwidth, and fragment shader ALUs.
Authentic answers regarding WebGL graphics benchmarking, hardware limits, and score calculations.
A GPU benchmark is a standardized, repeatable graphics workload designed to evaluate how rapidly and consistently your graphics processor can transform 3D vertices, compute lighting models, and rasterize pixels to the display buffer.
The benchmark executes compiled GLSL vertex and fragment shaders directly on your hardware via WebGL2/WebGL. It renders deterministic nested gimbal rings, orbiting crystalline polyhedra, and lit surface grids while measuring high-resolution frame times using performance.now().
When a 3D scene first initializes, the browser and graphics driver compile GLSL shaders and allocate vertex buffer memory (VBOs). This initial compilation causes momentary frame hitches. The 2.0-second warm-up stabilizes the pipeline so cold-start lag does not distort your official benchmark score.
The benchmark score uses a fully transparent, documented formula: Score = round(Avg FPS × 100 × (1 - Drop Rate %) × Preset Weight). Preset weights reflect geometric density and render resolution (Quick = 0.75, Balanced = 1.0, Performance = 1.35, Extreme = 1.75). No arbitrary synthetic numbers are used.
No. Modern web browsers operate within strict security sandboxes that prevent web code from accessing motherboard sensor diodes or low-level thermal registers. Any browser tool displaying temperature without desktop companion software is fabricating values.
No. Standard WebGL APIs do not expose operating system GPU utilization percentages or system-wide VRAM allocation due to privacy and side-channel protections. We only display verified parameters like maximum texture size and viewport limits.
A GPU benchmark runs a controlled, timed, and repeatable workload to measure performance scores and frame pacing. A GPU stress test applies continuous, maximum-intensity compute pressure for minutes to test thermal throttling, cooling stability, and driver recovery under extreme heat.
Web browsers synchronize animation loops (requestAnimationFrame) to your monitor's physical refresh rate via VSync. On a 60Hz display, the browser will cap frame delivery at 60 FPS regardless of GPU power.
A frame drop is recorded when a frame interval exceeds 25.0 milliseconds, which corresponds to dropping below 40 FPS on standard displays. Frame drops identify momentary hitches caused by background processes or driver pipeline stalls.
Render scale directly multiplies the internal canvas drawing buffer width and height. At 150%, your GPU computes lighting and rasterization for 2.25x more pixels before downsampling, heavily challenging pixel fillrate capacity.
Yes. Any modern laptop, desktop, tablet, or smartphone with a WebGL2/WebGL capable browser can run the benchmark. On laptops, keep your charger plugged in to avoid battery-saver GPU clock throttling.
Yes. Web browsers aggressively throttle background tabs to 1 FPS to conserve power and battery. Keep this tab active and focused throughout the benchmark duration for accurate results.
If a GPU driver encounters an operating system timeout (TDR) or runs out of execution time during heavy workloads, the OS restarts the graphics driver. Our benchmark safely traps this event without crashing the browser tab.
No under normal operating conditions. Modern graphics processors have built-in firmware safeguards that throttle clock speeds or limit power if thermal limits are approached. You can stop the benchmark at any time.
Some privacy-focused browsers (such as Firefox with resist-fingerprinting or Safari) mask specific hardware strings to protect user identity. On Windows Chromium browsers, it displays the underlying DirectX translation layer (ANGLE).
Select the same preset, close background 3D games or video rendering applications, ensure your device is plugged into AC power, and run the benchmark with the browser window maximized.
