Iphampu yokulinganisa ibizwa nangokuthi iphampu yokulinganisa noma iphampu elinganayo. Iphampu yokulinganisa iyiphampu ekhethekile yokuhambisa ephumelelayo engahlangabezana nezidingo zezinqubo ezahlukahlukene zobuchwepheshe eziqinile, inezinga lokugeleza elingalungiswa ngokuqhubekayo ngaphakathi kobubanzi obungu-0–100% futhi isetshenziselwa ukudlulisa uketshezi (ikakhulukazi uketshezi olubolayo)
Iphampu yokukala iwuhlobo lomshini wokudlulisa uketshezi futhi isici sayo esivelele ukuthi ingagcina ukugeleza okuqhubekayo kungakhathaliseki ukuthi ingcindezi yokukhipha ingakanani. Ngephampu yokukala, imisebenzi yokudlulisa, ukukala kanye nokulungisa ingaqedwa ngasikhathi sinye futhi ngenxa yalokho, inqubo yokukhiqiza ingenziwa lula. Ngamaphampu amaningi okukala, izinhlobo eziningana zemidiya zingafakwa enkambisweni yezobuchwepheshe ngesilinganiso esinembile bese zixutshwa.
