glmark2 vs WhatFPS Benchmark

glmark2 is a free graphics benchmark for OpenGL 2.0 and OpenGL ES 2.0. Its default suite runs scenes covering workloads such as building, textures, shading, bump, buffers, terrain, and shadows, then prints a glmark2 score. Users can specify custom benchmarks through command-line options or benchmark files. Results can be exported to XML or CSV, and available result details include CPU time and shader compilation time. The project documents Linux builds for DRM, Wayland, and X11, including desktop GL and GLESv2 variants, and provides instructions for building and installing an Android APK. Windows support is recorded through WGL and ANGLE-EGL. Building uses Meson and Ninja and requires Meson 0.47 or newer, libpng 1.6, window-system development files, and applicable GL or GLES libraries. On Android, arguments can come through an intent extra or an arguments file, with intent arguments taking precedence when supplied. The Android version ignores several X11 options, including validation, off-screen, fullscreen, and scene-list options. The project is licensed under GPLv3 and is provided without warranty.

WhatFPS Benchmark is a free Windows 10/11 benchmark for gaming PCs, measuring GPU, CPU, RAM, and disk performance. Graphics tests cover DX11, DX12, DX12 Ultimate, and Vulkan. GPU workloads include three 3D scenes plus a stress test for compute, memory bandwidth, textures, and fill rate. CPU tests cover floating point, integer, SIMD/AVX, single-thread performance, cache latency, and DX11 draw calls. RAM tests measure read, write, and triad bandwidth along with DRAM latency. Disk tests measure sequential reads, 4K random IOPS, and p99 latency. Results appear on a public leaderboard with percentiles for comparing measured systems. Runs are signed in the app and checked for plausible values and replay attacks; unverified runs are excluded. The app collects hardware information and test-time clocks and temperatures, but not files, browsing history, or other processes. In-game FPS tracking is optional. Installation is only through the Microsoft Store, with automatic updates. It does not support Mac or Linux. Processors without AVX2 cannot run it, and weaker systems with integrated graphics or under 6 GB of graphics memory may freeze during 4K scenes. Scores and methodology may change during beta.
