Read full description

Vector Search Bench is a high-signal, no-nonsense benchmark suite for vector similarity search on iPhone. Measure how fast and stable your device can score embeddings using the CPU (Accelerate/vDSP) versus the Apple Neural Engine (Core ML)—with real metrics you can trust. What you can benchmark Exact Top-K vector search (dot-product similarity) CPU path: Accelerate / vDSP optimized scoring NPU path: Core ML Dense inference tuned for Neural Engine scheduling Query-by-query execution with repeatable timing Intricate performance metrics Latency distribution: median, p95 Throughput: QPS Recall@K vs CPU reference (sanity check) Memory footprint and dataset sizing knobs Built for real-world AI systems

Volume Shader is the viral Volume Shader BM GPU test, built natively for iPhone and iPad. The Mandelbulb ray march runs in Metal on your iPhone or iPad. WHAT YOU CAN DO • Run Volume Shader BM at Simple, Standard, Advanced, or Extreme • Use Standard + 30 seconds when you want a score you can compare • Drag to rotate, pinch to zoom, and pan. Explore does not save a score. • Time CPU and memory on the same device • See GPU, memory, display, storage, and thermal state • Walk a display, touch, haptics, speaker, and battery checkup HEAT AND BATTERY This is a real GPU workload. The device can get warm and the battery will drain faster while a test is running. Extreme asks for confirmation. The app stops itself if iOS reports a critical thermal state. ADS Volume Shader is free and shows labeled native ads on Test, Device, and Checkup. Ads sit below the main content on those screens. They do not overlay the GPU test or fullscreen checkup steps. You can report an ad from the AdChoices icon on the ad. PRIVACY No account. Tests, history, and checkup marks stay on this device. Nothing is uploaded. If you tap Share, iOS’s share sheet sends only what you chose to the app you pick. Ads use the ads SDK described in the privacy policy.
