## What is Vector Search Bench?

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
