Summary

Intel's latest performance tests demonstrate that Intel Xeon server architectures significantly outperform AMD EPYC processors in vector search workloads, a critical component for AI-powered systems like semantic search, recommendation engines, and generative AI. Benchmarks using Redis Open Source 8.2 with Intel® Scalable Vector Search (Intel® SVS) and Faiss (Facebook AI Similarity Search) show Intel Xeon 6980P delivering up to 2x higher queries per second in Redis and up to 1.9x higher performance in Faiss compared to AMD EPYC 9965. Intel SVS, a software library, optimizes vector indexing, compression, and dimensionality reduction, enabling fast similarity search with reduced memory usage on Intel Xeon platforms. These results highlight the importance of processor architecture for high-dimensional similarity computations in meeting performance and cost goals for scalable AI applications.

Key takeaway

For MLOps Engineers and CTOs evaluating infrastructure for AI workloads, Intel Xeon processors, particularly when paired with Intel® Scalable Vector Search (Intel® SVS), offer a compelling performance advantage over AMD EPYC. Your teams should prioritize Intel Xeon platforms to achieve up to 2x higher queries per second in Redis and 1.9x higher Faiss performance, ensuring more efficient and scalable vector search for RAG, recommendation engines, and other AI applications.

Key insights

Intel Xeon processors, especially with Intel SVS, offer superior vector search performance over AMD EPYC.

Principles

• Processor architecture directly impacts vector search latency and throughput.
• Optimized indexing and compression reduce memory usage and accelerate search.
• High memory bandwidth and large cache improve high-dimensional search.

Method

Benchmarking involved Redis Open Source 8.2 (with HNSW and SVS) and Faiss, using Cohere 768, SIFT 128, and DBpedia 1536 datasets on Intel Xeon 6980P/6972P and various AMD EPYC processors.

In practice

• Deploy Intel SVS on Intel Xeon for scalable, low-latency similarity search.
• Utilize Redis with Intel SVS for real-time, large-scale RAG systems.
• Consider Faiss on Intel Xeon for flexible, high-performance batch inference.
