CPUsta

CPUsta is a web-based reference resource and community platform devoted to central processing units (CPUs). It aggregates specifications, performance data, and educational material about processors from a broad range of vendors and eras. The project was founded in 2010 by hardware enthusiasts and is maintained by volunteers and professional editors who curate content to ensure accuracy and accessibility.

Core content includes individual CPU profiles with specifications such as model name, core count, base and boost clocks, cache hierarchy, lithography, microarchitecture, thermal design power, socket compatibility, and supported instruction sets. Pages may also include release dates, integrated graphics information, and notes on multi-chip configurations. The site hosts explanatory articles on topics like pipelines, caches, memory hierarchy, and power efficiency, along with historical context about processor generations. Benchmarks are presented from user submissions and laboratory tests, with standardized notes on test conditions to enable cross-CPU comparisons.

Data governance is modeled by a tiered editorial process: new entries and edits undergo verification by editors, with community moderation and citations to official specifications and independent benchmarks.

Community and impact: CPUsta serves students, hobbyists, and professionals as a quick reference and learning resource. It is frequently cited as a supplementary source alongside vendor documentation, technical articles, and academic materials. Because much of the data is user-contributed, users are encouraged to review methodology and cross-check against primary sources.

Limitations: Coverage of older or obscure CPUs may be incomplete; benchmarking data can reflect biases in test setups and submission quality. The platform emphasizes transparency about data provenance and testing conditions to mitigate these issues.
