Intel’s New CPU Powers Faster Vector Search - Qdrant

What this post added

This post presents benchmark results from Qdrant's R&D division, demonstrating that Intel's 5th gen Xeon processors (Emerald Rapids) offer up to 38% faster vector search compared to the 4th gen Sapphire Rapids. Tests on machines with 32 cores showed 1.38x faster query execution and a 2.79x reduction in latency compared to Sapphire Rapids. The findings suggest that CPUs are a strong choice for vector search, especially for enterprise-scale AI/ML applications, and Qdrant recommends specific core ranges for optimal performance.
