Binning is a term vendors use for categorizing components, including CPUs, GPUs (aka graphics cards) or RAM kits, by quality and performance. While components are designed to achieve a certain performance level, sometimes the final product fails to meet those standards, due to the complexities associated with manufacturing PC components. After manufacturing, vendors conduct testing and bin the component based on its performance results.
And vendors may bin-out high-performance components by disabling some of their capabilities and marketing them as lower performance to meet their own supply/demand needs. For instance, if a high-end CPU isn’t selling so hot right now, supply would be high. A vendor could disable compute units in some of these high-end CPUs so that they’ll fit into the more highly demanded mainstream market and have a better chance of selling.
These processes can also happen with GPUs or RAM, with vendors disabling compute units and binning a product into a lower performance category.
Alternatively, continuing the Intel CPU example, processors that offer higher clock speeds amongst other CPUs of the same model may be binned into Intel’s K line of processors (identifiable by the “K” at the end of their name), which are unlocked and, therefore, can be overclocked. In the world of CPUs, these variances in performance among the same CPU models are due to the intricate nuances of CPU manufacturing. Yes, two CPUs with the same model number can offer differ performance. These uncertainties are referred to as the silicon lottery.
