The term vanilla describes hardware or software with only the default specifications and no add-ons or changes. For example, a stock NVIDIA video card might be described as “vanilla.” In contrast, a “non-vanilla” video card might use a NVIDIA chipset with modifications or additions by a third-party manufacturer. When referring to software, vanilla could refer to a vanilla version of the Microsoft Windows operating system and not the version of Microsoft Windows packaged with an OEM computer.
