Morero oa Raspberry Pi Mofuta o tsoetseng pele oa boto ea Raspberry Pi 4 e tlang le 8GB ea RAM. Litsenyehelo tsa khetho e ncha ea boto $75. Ha ho bapisoa, liboto tse nang le 2 le 4 GB ea RAM li rekisoa ka $ 35 le $ 55, ka ho latellana.
Chip ea BCM2711 e sebelisitsoeng ka botong e u lumella ho sebetsana le memori e fihlang ho 16 GB, empa ha boto e ne e ntlafatsoa selemong se fetileng, ho ne ho se na lichifi tse loketseng tsa LPDDR4 SDRAM tse rekisoang. Hona joale Micron o lokolotse li-chips tse hlokahalang tsa 8 GB, motheong oa hore ho hahiloe phetolelo e ncha ea Raspberry Pi 4. Ho fana ka chip ea 8 GB LPDDR4 SDRAM e matla haholo ho boetse ho hloka ntlafatso e nyenyane ea lipotoloho tsa matla le ho falla. mofetoleli oa pulse ho tloha sebakeng se haufi le lihokelo tsa USB 2.0 ho ea sebakeng se haufi le USB-C.
Ha re hopoleng hore boto ea Raspberry Pi 4 e na le SoC BCM2711 mme e kenyelletsa li-cores tse 'ne tsa 64-bit ARMv8 Cortex-A72 tse sebetsang ho 1.5GHz le Accelerator ea litšoantšo tsa VideoCore VI e tšehetsang OpenGL ES 3.0 mme e khona ho khetholla boleng ba video ea H.265 4Kp60 (kapa 4Kp30 bakeng sa li-monitor tse peli). Boto e na le memori ea LPDDR4, molaoli oa PCI Express, Gigabit Ethernet, likou tse peli tsa USB 3.0 (hammoho le likou tse peli tsa USB 2.0), likou tse peli tsa Micro HDMI (4K), 40-pin GPIO, DSI (kamano ea skrineng), CSI (khamera khokahano) le chip ea puisano e se nang mohala e tšehetsang maemo a 802.11ac, e sebetsang ho 2.4GHz le 5GHz frequency le Bluetooth 5.0. Matla a ka fanoa ka koung ea USB-C (eo pele e neng e le USB micro-B), ka GPIO kapa ka mojule oa boikhethelo oa PoE HAT (Power over Ethernet). Litekong tsa ts'ebetso, Raspberry Pi 4 e feta Raspberry Pi 3B+ ka makhetlo a 2-4, le Raspberry Pi 1 ka makhetlo a 40.
