"Upgrade Chance" is a probability of a successful processor upgrade/downgrade from the FX-8320 (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 AMD FX-8320. 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.

AMD FX-8320 performance

The table below shows aggregate multi-threaded performance of the microprocessor compared to other Socket AM3+ CPUs with the same type of architecture. The performance value for many microprocessors was determined from more than 10 different real-world and synthetic benchmarks. For each benchmarked application, we calculated performance ratio between current processor and the FX-8320, and then averaged the results. Overall performance of parts, marked with (1), was estimated using their specifications, and tests of similar AMD Socket AM3+ products with Vishera core.
