SGI had a descriptive name. Bethesda Softworks is named after the city, SpaceX is short for "Space Exploration Technologies", IGN is literally a description of their site (they don't use the full name today but it's International Gaming Network). Epic Games and Tesla are less literal but still relate to their business.

The empty corporate sounding names are usually for conglomerates that need a neutral name so they don't put one of their brands over others, and B2B suppliers who need something unique for trademark purposes but don't really do the kind of marketing where they would need emotional impact.
