Raspberry Pi on suosituin kehittäjien yhden kortin tietokone, mutta nykyinen 4-sukupolvi on jo neljän vuoden ikäinen. Tämä ongelma poistuu lokakuussa. Raspberry Pi 5 saa jopa 2-3 kertaa enemmän suorituskykyä, kun prosessoriksi vaihtuu Broadcomin BCM2712.

Raspberry Pi -kortteja on myyty yli 50 miljoonaa kappaletta ja vaikka niitä on valmistettu 400 000 kappaleen kuukausivauhdilla, ostaminen on ollut viime aikoina vaikeaa. Suuri suosio ja pula tietyistä komponenteista on huono yhdistelmä.

Ennakkotietojen mukaan prosessorin nopeus kaksinkertaistuu 2,4 gigahertsiin. Tämä perustuu 16 nanometrin prosessissa valmistettuun kaksiytimiseen Cortex-A76-prosessoriin. Sen teho riittää PCIe 2.0 -väylään ja jo 4-versiosta tuttuun kahden 4K-näytön syöttöön micro-HDMI-väyliä pitkin.

Myös 40-nastainen perusliitäntä on paikallaan. Siitä saa lisäkortteja varten ulos jopa 5 voltin jännitteen. Uutena lisäkorttina on ennakkotietojen mukaan tulossa PoE-kortti eli ethernet-jota pitkin voidaan siirtää virtaa. Tallennukseen on tulossa kaksi liitäntää M.2 SSD -levyille. Toisen SSD-väylän voi käyttää kotelon sisäiseen tallennustilaan.

Uutta on myös reaaliaikakello. Sen lisääminen helpottanee monia projekteja.
