PerfDog vs WhatFPS Benchmark

PerfDog is a performance testing and analysis tool for applications and games, with real-time views of FPS, CPU, GPU, memory, frame time, and jank. Its listed platforms include Android, iOS, macOS, web, and Windows, with support also listed for Switch, PlayStation, and Xbox. PerfDog says tests need no root access or jailbreak, require no app changes, and add less than 1% overhead. It claims FPS precision of ±0.1, timestamps at 1 ms, and a 1000 Hz sample rate. AI-driven reports and bottleneck detection include one-click analysis of a single report. PerfDog CLI plus Service supports remote testing and CI/CD integration. Its cloud dashboard stores and manages test cases and supports team tasks and sharing. PerfDog MCP offers 15 tool interfaces, and its site shows workflow results being sent to WeCom and Lark. The free version is for non-profit organizations; research users can apply for a charity quota. Pricing for other use is available on request.

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.
