I-Raspberry Pi 4 noma i-Raspberry Pi 3B+, iyiphi engcono?

Ingabe ucabanga ukuthenga i-Raspberry Pi kodwa uzithole udabukile phakathi kwamamodeli akamuva? Njengoba i-Raspberry Pi ecosystem iqhubeka ikhula, ukukhetha imodeli efanele kungase kube nzima. Izinketho ezimbili ezidumile, i-Raspberry Pi 4 kanye ne-Raspberry Pi 3B+, zinikeza izici ezihlukene namazinga okusebenza, ahlinzekela izidingo ezihlukahlukene. Kulesi siqhathaniso, sizohlola umehluko oyinhloko phakathi kwalawa mamodeli ukuze sikusize wenze isinqumo unolwazi.

I-Raspberry Pi 4 vs Raspberry PI 3B+: CPU, RAM, kanye Nezithombe

Uma kukhulunywa ngamandla okucubungula, i-RAM, namandla ezithombe, umehluko phakathi kwe-Raspberry Pi 4 ne-Raspberry Pi 3B+ uyabonakala. I-Raspberry Pi 4 iziqhayisa nge-quad-core ARM Cortex-A72 CPU egijima ku-1.5 GHz, okuyisinyathelo esisuka ku-Raspberry Pi 3B+'s quad-core ARM Cortex-A53 CPU ku-1.4 GHz. Lo mehluko uphumela ekusebenzeni okuthuthuke kakhulu kwezinhlelo zokusebenza ezisebenza ngekhompyutha.

Mayelana nenkumbulo, i-Raspberry Pi 4 inikeza izinketho nge-2GB, 4GB, noma 8GB LPDDR4 SDRAM, enikeza abasebenzisi ukuguquguquka okukhulu kanye namandla okwenza izinto eziningi kanye nokusingatha imisebenzi eyinkimbinkimbi. I-Raspberry Pi 3B+, ngakolunye uhlangothi, ikhawulelwe ku-1GB LPDDR2 SDRAM, okungenzeka ikhawulele ekusebenzeni okudinga kakhulu.

Ngokuqondene nezithombe, i-Raspberry Pi 4 iya phambili ngephrosesa yezithombe ze-VideoCore VI esekela i-OpenGL ES 3.x. Lokhu kuvumela ukuphathwa okungcono kwezinhlelo zokusebenza nemisebenzi yesimanje, into i-Raspberry Pi 3B+ kanye nephrosesa yayo yezithombe ze-VideoCore IV esekela i-OpenGL ES 2.0 engase ibe nzima nayo. Le ntuthuko ivula amathuba amasha kubasebenzisi abafuna ukusebenza ngokuphuma kwesithombe esisebenza kahle kakhulu.

Amabhentshimakhi okusebenza: I-Raspberry Pi 3B+ vs Raspberry Pi 4

Ekuhlolweni kwebhentshimakhi yekhanda kuye-ekhanda, i-Raspberry Pi 4 ihlala idlula i-Raspberry Pi 3B+. Ngokusebenza okusheshayo kwe-CPU, njengoba kufakazelwa ngamathuluzi okulinganisa afana ne-Sysbench, ukuphatha ihluzo ephakeme kakhulu ngenxa ye-GPU yayo ethuthuke kakhulu, i-Raspberry Pi 4 ingumholi ocacile ngokwamandla aluhlaza.

Uma kukhulunywa ngezinhlelo zokusebenza zomhlaba wangempela, abasebenzisi bazoqaphela ukuthi i-Raspberry Pi 4 iphatha imisebenzi eyinkimbinkimbi njengokucubungula ividiyo nokubala ngekhompyutha ngempumelelo kakhulu. Ukusebenza kwegeyimu kuphinde kubonise ukuthuthuka okubonakalayo, ngosekelo lwamazinga e-OpenGL esimanjemanje okuvula umnyango wentuthuko yesikhathi esizayo kumakhono egeyimu ye-Raspberry Pi.

Ukweqa okukhulu ekusebenzeni kubonakala emandleni e-Raspberry Pi 4 okufunda nokubhala idatha kumadrayivu e-USB angaphandle, namachweba ayo e-USB 3.0 ahlinzeka ngesivinini sokudlulisa esidlula kakhulu amachweba we-USB 2.0 atholakala ku-Raspberry Pi 3B+. Lesi sithuthukisi sisodwa sishintsha igeyimu kubasebenzisi abadinga ukucutshungulwa kwedatha okusheshayo nokudluliswa.

Ukuthuthukiswa Kokuxhumana: Izimbobo kanye Namakhono Angenantambo

I-Raspberry Pi 4 inezithuthukisi eziningi zokuxhumeka kuneyangaphambili. Ngokungezwa kwamachweba amabili e-USB 3.0, abasebenzisi bazobona isivinini sokudlulisa idatha esiphezulu kumadivayisi axhunyiwe. Ukuxhumeka okungenantambo nakho kubona ukuthuthuka ngokufakwa kwe-Bluetooth 5.0, okunikeza ububanzi obude kanye namazinga okudlulisa idatha asheshayo kune-Bluetooth 4.2 etholakala ku-Raspberry Pi 3B+.

Ngaphezu kwalokho, i-Raspberry Pi 4 yethula amachweba amabili e -HDMI , asekela ukulungiswa kwe-4K echwebeni elilodwa, ngaleyo ndlela evumela ukusetshenziswa kokusetha kwe-multi-monitor - ukuthuthuka okukhulu kunokukhishwa okukodwa kwe-1080p kwe-Raspberry Pi 3B+.

Izidingo zamandla kanye nokuphathwa kokushisa

Izidingo zamandla kanye nokuphathwa kokushisa kuyizinto ezibalulekile okufanele uzicabangele lapho ukhetha phakathi kwe-Raspberry Pi 4 kanye ne-Raspberry Pi 3B+. Ihadiwe ethuthukisiwe ye-Raspberry Pi 4 idinga ukunikezwa kwamandla okuqinile, okukwazi ukuletha okungenani i-3A, uma kuqhathaniswa ne-Raspberry Pi 3B+ engasebenza emthonjeni wamandla we-5V / 2A.

Isidingo samandla esikhulayo se-Raspberry Pi 4 siphumela ekusetshenzisweni kwamandla okuphezulu kanye nokukhiqizwa kokushisa. Ukuvimbela ukushisa ngokweqile kanye nokulimala okungaba khona ebhodini, abasebenzisi kufanele bacabangele ukutshala imali kuzixazululo zokupholisa ezengeziwe ezifana nama-heatsink namafeni. Lezi zinsiza zisiza ukuqeda ukushisa ngempumelelo, ziqinisekisa ukusebenza okuzinzile nokuphila isikhathi eside kwe-Raspberry Pi 4.

Lapho ukhetha ukunikezwa kwamandla kwe-Raspberry Pi 4, kubalulekile ukukhetha ehlangabezana nezicaciso ezinconyiwe ukuze ugweme izinkinga ezihlobene nokungalethwa kwamandla anganele. Ukwengeza, ukuqapha okuvamile kwezinga lokushisa lebhodi kuyanconywa, ikakhulukazi ngesikhathi sokusetshenziswa kakhulu, ukuze kuqinisekiswe ukusebenza kahle nokuvimbela ukushisa ngokweqile.

Kafushane, izidingo zamandla ezikhulayo ze-Raspberry Pi 4 kanye nezidingo zokuphatha okushisayo kufanele kucatshangelwe lapho kubhekwa ukufaneleka kwayo kuphrojekthi yakho. Ukunikezwa kwamandla okufanelekile kanye nezixazululo zokupholisa kubalulekile ukuze kuqinisekiswe ukusebenza okuzinzile nokuhlala isikhathi eside kwedivayisi.

Isiphetho kanye Nendlela Yokwenza Izinqumo

Lapho unquma phakathi kwe-Raspberry Pi 4 ne-Raspberry Pi 3B+, kubalulekile ukucabangela izidingo zephrojekthi yakho ethile. Izici ezithuthuke kakhulu ze-Raspberry Pi 4 zingadingeka emisebenzini edingeka kakhulu kanye nalabo abafuna ukusebenza okungcono kakhulu okutholakala endaweni yesikhulumi se-Raspberry Pi. Kodwa-ke, i-Raspberry Pi 3B+ isalokhu iyinketho ebalulekile yamaphrojekthi anezidingo ezinesizotha kanye nemikhawulo yesabelomali.

Kubalulekile ukuhlola izimfuno zohlelo lwakho lokusebenza, okuhlanganisa isivinini sokucubungula, izidingo zezithombe, izinketho zokuxhuma, ukusetshenziswa kwamandla, kanye nezingqinamba zesabelomali, ukuze wenze isinqumo esinolwazi ngokuthi iyiphi imodeli ye-Raspberry Pi ongakhetha kuyo. Womabili amamodeli ayaqhubeka nokwandisa i-Raspberry Pi ecosystem, enikeza abasebenzisi izinhlobonhlobo zezinketho ezihambisana nezidingo zabo zephrojekthi ezihlukile.
