Coreinfo 4.0

Coreinfo is a Microsoft command-line tool, part of the Sysinternals suite, aimed at displaying detailed information about the topology and features of processors in Windows systems.

The utility shows how logical processors are organized into physical cores, CPU sockets, processor groups, and NUMA (Non-Uniform Memory Access) nodes, in addition to presenting data about the different levels of cache available. This information helps you understand how the operating system perceives and distributes processing.

Coreinfo collects data using low-level APIs of Windows itself, responsible for exposing the internal structure of the hardware. The result is presented directly in the console, in maps and tables indicating the relationship between cores, caches, groups, and memory nodes.

The program offers various execution parameters that allow filtering the type of information displayed, including details about cores and threads, processor characteristics, cache organization, NUMA access costs, virtualization support, and advanced CPU features.

Executed via the Command Prompt, Coreinfo is used in technical hardware analyses, performance diagnostics, and CPU affinity studies, being common in testing, development, and system administration environments that require precise knowledge of the processor structure.
