upos.info: Latency, Throughput, and Port Usage Information For Instructions on Recent Intel Microarchitectures

This website provides more than 200,000 pages with detailed latency, throughput, and port usage data for most x86 instructions on all generations of Intel’s Core architecture (i.e., from Nehalem to Coffee Lake). While such data is important for understanding, predicting, and optimizing the performance of software running on these microarchitectures, most of it is not documented in Intel’s official processor manuals.
