Comparison of Texas Instruments graphing calculators

This is a comparison of graphing calculators manufactured by Texas Instruments, a major manufacturer of these. Graphing calculators is a class of hand-held calculator that is capable of plotting graphs and solving complex functions.

The following table compares general and technical information for a selection of common and uncommon Texas Instruments graphing calculators. Many of the calculators in this list have region-specific models that are not individually listed here, such as the TI-84 Plus CE-T, a TI-84 Plus CE designed for non-French European markets. These region-specific models are usually functionally identical to each other, aside from minor cosmetic differences and circuit board hardware revisions. See the individual calculators' articles for further information.
