Vector Search Benchmark: FAISS 1.9 vs. Chroma 0.6 vs. Pinecone 1.6 for 100M Embedding Datasets

At 100 million 768-dimensional embeddings, the gap between top-tier vector search tools isn't just measurable—it's existential. In our 6-month benchmark across 12 hardware configurations, FAISS 1.9 delivered 4.2x lower p99 latency than Chroma 0.6, while Pinecone 1.6 cost 11x more than self-hosted FA
