Iphampu yemitha ibizwa nangokuthi ipompo yomthamo noma iphampu elinganayo. Iphampu yokulinganisa iyiphampu ekhethekile yokususa ekwaziyo ukuhlangabezana nezimfuneko zezinqubo zobuchwepheshe ezihlukahlukene eziqinile, inezinga lokugeleza elingalungiswa ngokuqhubekayo phakathi kwebanga elingu-0–100% futhi lisetshenziselwa ukudlulisa uketshezi (ikakhulukazi uketshezi olubolayo)
Iphampu yemitha iwuhlobo lwemishini edlulisa uketshezi futhi isici sayo esivelele ukuthi ingakwazi ukugcina ukugeleza okuqhubekayo kungakhathaliseki ingcindezi yokukhipha. Ngepompo yemitha, imisebenzi yokudlulisa, ukulinganisa kanye nokulungisa ingaqedwa kanyekanye futhi ngenxa yalokho, inqubo yokukhiqiza ingenziwa lula. Ngamaphampu amamitha amaningi, izinhlobo ezimbalwa zemidiya zingafakwa kwinqubo yobuchwepheshe ngengxenye enembile bese ixutshwa.
