Raspberry Pi 4 kapa Raspberry Pi 3B+, ke efe e molemo?
Raspberry Pi 4
Na u nahana ho reka Raspberry Pi empa u iphumana u arohane pakeng tsa mefuta ea morao-rao? Ha Raspberry Pi ecosystem e ntse e hola khafetsa, ho khetha mofuta o nepahetseng ho ka ba boima. Likhetho tse peli tse tsebahalang, Raspberry Pi 4 le Raspberry Pi 3B+, li fana ka likarolo tse fapaneng le maemo a ts'ebetso, tse fanang ka litlhoko tse fapaneng. Papisong ena, re tla hlahloba liphapano tsa bohlokoa lipakeng tsa mefuta ena ho u thusa ho etsa qeto u na le tsebo.
Raspberry Pi 4 vs Raspberry PI 3B+: CPU, RAM, le Graphics
Ha ho tluoa tabeng ea matla a ho sebetsa, RAM, le bokhoni ba litšoantšo, liphapang pakeng tsa Raspberry Pi 4 le Raspberry Pi 3B+ li bonahala hantle. Raspberry Pi 4 e na le quad-core ARM Cortex-A72 CPU e sebetsang ho 1.5 GHz, e leng mohato o tsoang ho Raspberry Pi 3B+'s quad-core ARM Cortex-A53 CPU ho 1.4 GHz. Phapang ena e fella ka ts'ebetso e ntlafetseng haholo bakeng sa lisebelisoa tse matla tsa lik'homphieutha.
Mabapi le mohopolo, Raspberry Pi 4 e fana ka likhetho tse nang le 2GB, 4GB, kapa 8GB LPDDR4 SDRAM, e fa basebelisi maemo a bonolo le monyetla oa ho etsa lintho tse ngata le ho sebetsana le mesebetsi e rarahaneng. Raspberry Pi 3B+, ka lehlakoreng le leng, e lekanyelitsoe ho 1GB LPDDR2 SDRAM, e kanna ea fokotsa ts'ebetso e boima haholo.
Ha e le litšoantšo, Raspberry Pi 4 e ea pele ka processor ea litšoantšo ea VideoCore VI e tšehetsang OpenGL ES 3.x. Sena se lumella ho ts'oaroa hamolemo ha lits'ebetso le mesebetsi ea sejoale-joale ea litšoantšo, ntho eo Raspberry Pi 3B+ le processor ea eona ea litšoantšo ea VideoCore IV e tšehetsang OpenGL ES 2.0 e ka thatafalloang le eona. Tsoelo-pele ena e bula menyetla e mecha bakeng sa basebelisi ba batlang ho sebetsa ka litšoantšo tse sebetsang hantle haholo.
Litekanyetso tsa Ts'ebetso: Raspberry Pi 3B+ vs Raspberry Pi 4
Litekong tsa benchmark tsa hlooho-ho-hlooho, Raspberry Pi 4 e lula e feta Raspberry Pi 3B+. Ka ts'ebetso ea CPU e potlakileng, joalo ka ha ho pakoa ke lisebelisoa tsa benchmark joalo ka Sysbench, ho ts'oaroa ha litšoantšo tse holimo ka lebaka la GPU ea eona e tsoetseng pele, Raspberry Pi 4 ke moetapele ea hlakileng mabapi le matla a tala.
Ha ho tluoa lits'ebetsong tsa lefats'e la nnete, basebelisi ba tla hlokomela hore Raspberry Pi 4 e sebetsana le mesebetsi e rarahaneng joalo ka ts'ebetso ea video le komporo ka mokhoa o atlehileng haholoanyane. Ts'ebetso ea lipapali e boetse e bonts'a ntlafatso e hlokomelehang, ka ts'ehetso ea litekanyetso tsa sejoale-joale tsa OpenGL tse bulang monyetla oa tsoelo-pele ea nako e tlang ho bokhoni ba papali ea Raspberry Pi.
Ho tlola ho hoholo ts'ebetsong ho bonoa bokhoni ba Raspberry Pi 4 ba ho bala le ho ngola data ho li-drive tsa kantle tsa USB, ka likou tsa eona tsa USB 3.0 tse fanang ka lebelo la phetisetso le phahametseng likou tsa USB 2.0 tse fumanehang ho Raspberry Pi 3B+. Ntlafatso ena feela e fetola papali bakeng sa basebelisi ba hlokang ts'ebetso ea data e potlakileng le ho fetisoa.

Tsoelo-pele ea Khokahano: Boema-kepe le Bokhoni ba Waelese
Raspberry Pi 4 e na le lintlafatso tse ngata tsa khokahano ho feta e neng e le teng pele ho eona. Ka ho eketsoa ha likou tse peli tsa USB 3.0, basebelisi ba tla ba le lebelo le phahameng la phetisetso ea data bakeng sa lisebelisoa tse hokahantsoeng. Khokahano ea waelese e boetse e bona lintlafatso ka ho kenyelletsoa ha Bluetooth 5.0, e fanang ka mefuta e telele le litefiso tse potlakileng tsa phetisetso ea data ho feta Bluetooth 4.2 e fumanehang ho Raspberry Pi 3B+.
Ho feta moo, Raspberry Pi 4 e hlahisa dikou tse pedi tsa HDMI , tse tshehetsang qeto ya 4K koung e le nngwe, ka hona e nolofalletsa tshebediso ya di-setup tsa multi-monitor - ntlafatso e kgolo hodima tlhahiso e le nngwe ya 1080p ya Raspberry Pi 3B+.
Litlhoko tsa Matla le Tsamaiso ea Thermal
Litlhoko tsa motlakase le taolo ea mocheso ke lintho tsa bohlokoa tseo u lokelang ho nahana ka tsona ha u khetha pakeng tsa Raspberry Pi 4 le Raspberry Pi 3B+. Thepa e ntlafalitsoeng ea Raspberry Pi 4 e hloka phepelo ea motlakase e matla haholoanyane, e khonang ho fana ka bonyane 3A, ha e bapisoa le Raspberry Pi 3B+ e ka sebetsang mohloling oa motlakase oa 5V / 2A.
Tlhokahalo e eketsehileng ea matla ea Raspberry Pi 4 e fella ka tšebeliso e phahameng ea matla le tlhahiso ea mocheso. Ho thibela mocheso o feteletseng le tšenyo e ka bang teng ho boto, basebelisi ba lokela ho nahana ka ho tsetela ho litharollo tse ling tsa ho pholisa joalo ka heatsinks le libapali. Lisebelisoa tsena li thusa ho theola mocheso ka mokhoa o atlehileng haholoanyane, ho netefatsa ts'ebetso e tsitsitseng le bophelo bo bolelele ba Raspberry Pi 4.
Ha u khetha phepelo ea motlakase bakeng sa Raspberry Pi 4, ho bohlokoa ho khetha e lumellanang le lintlha tse khothaletsoang ho qoba litaba tse amanang le phepelo ea motlakase e sa lekaneng. Ho feta moo, ho khothaletsoa ho lekola mocheso oa boto khafetsa, haholo nakong ea ts'ebeliso e boima, ho netefatsa ts'ebetso e nepahetseng le ho thibela mocheso o feteletseng.
Ka kakaretso, litlhoko tsa matla a Raspberry Pi 4 tse ntseng li eketseha le litlhoko tsa taolo ea mocheso li lokela ho nahanoa ha ho nahanoa ka ho lekana ha eona bakeng sa projeke ea hau. Lisebelisoa tse nepahetseng tsa motlakase le litharollo tsa ho pholisa li bohlokoa ho netefatsa ts'ebetso e tsitsitseng le nako e telele ea sesebelisoa.
Qetello le Mekhoa ea ho Etsa Liqeto
Ha u etsa qeto lipakeng tsa Raspberry Pi 4 le Raspberry Pi 3B+, ho bohlokoa ho nahana ka litlhoko tsa projeke ea hau e ikhethileng. Likarolo tse tsoetseng pele haholo tsa Raspberry Pi 4 li kanna tsa hlokahala bakeng sa mesebetsi e batloang haholo le ba batlang ts'ebetso e ntle e fumanehang sethaleng sa Raspberry Pi. Leha ho le joalo, Raspberry Pi 3B+ e ntse e le khetho ea bohlokoa bakeng sa merero e nang le litlhoko tse itekanetseng le lithibelo tsa tekanyetso.
Ho bohlokoa ho lekola litlhoko tsa kopo ea hau, ho kenyelletsa lebelo la ts'ebetso, litlhoko tsa lits'oants'o, likhetho tsa khokahanyo, tšebeliso ea matla, le mathata a lichelete, ho etsa qeto e nang le tsebo mabapi le hore na mofuta oa Raspberry Pi o tla khetha ofe. Mefuta ena ka bobeli e ntse e tsoela pele ho holisa Raspberry Pi ecosystem, e fa basebelisi mefuta e mengata e fapaneng ea likhetho tse lumellanang le litlhoko tsa bona tse ikhethang tsa projeke.
