In terms of head to head utility, Opera and Firefox are close competitors. Opera may have an advantage in one aspect with its compatibility with and access to Chrome’s huge extension library. But one significant factor to consider is the fact that Opera, because it’s built on Chromium, is a processor-hungry browser with its RAM consumption comparable to Chrome, which is known for its high CPU usage.
O ran cymharu gwasanaethau, mae Opera a Firefox yn gystadleuwyr agos. Efallai bod gan Opera fantais mewn un agwedd gyda’i gydnawsedd â chasgliad estyniadau enfawr Chrome a’i fynediad iddo. Ond un ffactor arwyddocaol i'w ystyried yw'r ffaith bod Opera, oherwydd ei fod wedi'i adeiladu ar Chromium, yn borwr sy'n drwm ar y proseswr gyda'i ddefnydd RAM yn debyg i Chrome, sy'n adnabyddus am ei ddefnydd uchel o'r CPU.
