What Is Binning? A Basic Definition (2022)
Binning is a process used by manufacturers to sort chips (CPUs, GPUs, RAM) based on quality, performance, and power efficiency after production. Higher-binned parts can achieve higher clock speeds at lower voltages, while lower-binned parts are downclocked or sold as cheaper models. This practice explains why two identical-looking components can perform differently.
Background
Binning is the semiconductor-industry practice of sorting finished chips (CPUs, GPUs) by performance after manufacturing. Because no two chips come off the wafer identical, manufacturers test each one, then group ("bin") them by clock speed, power draw, or defect count. The best chips become higher-priced, faster models (e.g., a Core i9), while weaker ones are sold as lower-tier models (e.g., a Core i5) or get disabled features trimmed off. This is why two chips with the same underlying silicon can perform differently — and why "winning the silicon lottery" (getting a chip that runs faster or cooler than its bin suggests) is a concept in PC overclocking.
