Qualcomm an aiki na dogon lokaci tare da GPU Adreno. A farko versions fara bayyana a shekara ta 2009 da kuma ya riga ya dauka a kan kasuwa da kuma masu amfani da hankali. Yanzu akwai bakwai sarrafawa tare da wannan graphics totur. A general, ba su bambanta da juna. Wani lokaci m vibration mitoci.

Akwai har yanzu mutanen da suke da smart phones da Adreno 305. Reviews da video processor a kananan yawa. An sa da cewa shi ne wani ɓangare na mobile na'urar, don haka shi samun wani smartphone sake dubawa, maimakon ta mutum aka gyara.

An sani cewa model 2013, wanda ya karbi chipset nufin da talakawan farashin kashi, da kuma nuna barga yi, wanda bai tsaya fita da wani abu na musamman. Sarrafawa tare da wannan cibiya yi aiki da kyau, godiya ga ikon jingina dabaru adana cin gashin na na'ura na dogon lokaci.

Babban hasara na sayen irin wannan na'urar yana dauke da cewa mai amfani iya kula da Snapdragon 400 samu a Internet bayani dalla-dalla, bincika dukan da kuma samun shi. Amma a gaskiya shi ya juya daga cewa chipset da ɗan weaker a wasu lokuta hallara don gwajin gazawar. Wadannan matsaloli da aka sa da cewa a dunkule Snapdragon 400 zai sau da yawa nufin 'yan gyare-gyare, wanda, ko da yake ya Adreno 305, sauran Manuniya iya bambanta da yawa.

Overall, da graphics da kyau. Ta ba su ja zato toys, amma a low saituna jimre da kusan dukkan ayyukan da "Play Store". Babban drawback na graphics da kuma sarrafawa daga Qualcomm dauke zafi fiye da kima a yau.
