Test płyt głównych LGA 1150 mATX z chipsetem B85

Przegląd ośmiu konstrukcji dedykowanych mniej zamożnym użytkownikom procesorów Intel Haswell.

Audio

Nasze testy wykazały, że nie ma wyraźnie lepszych i wyraźnie gorszych kodeków audio zainstalowanych na płytach z tego zestawienia, choć oczywiście występują różnice. Poniżej umieściliśmy szesnaście tabel z wynikami, po dwie dla każdej konstrukcji.
