"Upgrade Chance" is a probability of a successful processor upgrade/downgrade from the Core i3-2100 (original CPU) to a specific model. This number is calculated as a percentage of all motherboards, compatible with both original and upgrade CPUs, compared to the number of motherboards, that support the original Intel i3-2100. The number "100%" means that all motherboards, that work with the original model, also work with the upgrade CPU. The number "0%" means that none of the boards, that support the original CPU, will support the upgrade processor. The manufacturers do not always test or publish results for obscure and unreleased models, and in some cases for OEM only processors, as a result they tend to have much lower scores than more common desktop/mobile counterparts.

Intel Core i3-2100 performance

The chart below shows aggregate multi-threaded performance of the microprocessor compared to other Socket 1155 processors with the same type of architecture. The performance value for many CPUs was determined from more than 10 different real-world benchmarks and synthetic tests. For each benchmarked application, we calculated performance ratio between current CPU and the Core i3-2100, and then averaged the results. Overall performance of chips, marked with (1), was estimated using their specifications, and benchmarks of similar Intel Socket 1155 processors with Sandy Bridge core.
