La Ukusajingijolo Pi 4 iyabuyekezwa, futhi manje yeqa umkhawulo we-4GB ebekiwe ezinhlotsheni ezedlule zeModeli B yale SBC. Manje usungathenga iRasbperry Pi 4 Model B 8 GB ngentengo cishe eyi- $ 75. Isibalo sememori esisemqoka kakhulu esizokuvumela ukuthi usebenzise izinqubo eziningi ngokushesha okukhulu.
Cishe unyaka ngemuva kokuqaliswa kwe-Raspberry Pi 4, umsebenzi onzima wabathuthukisi bayo uyabuya ukunikeza imiphumela yokwanelisa abasebenzisi abafuna kakhulu. Kakade iPi 4 ibiyimpumelelo, cishe kuthengiswe amayunithi angama-3 million, ngohlobo lwayo lwe-1GB, 2GB kanye ne-4GB. Impela kusha I-SBC ene-8 GB kuzosiza lelo nani liqhubeke nokukhula.
Umsebenzi ugxile ekunciphiseni amazwe angenamsebenzi nasekuthuthukiseni ukusetshenziswa ngemithwalo yomsebenzi, kanye nokuqala nge-Vulkan graphical API enamandla, imodi yokuqalisa ye-PXE yenethiwekhi, kanye nokulungiswa kwamaphutha, njll. Manje bajabule ngokukhishwa kwale nguqulo ye-8GB RAM. kwabathanda abangenelisekile ngalokho osekuvele kunakho.
Futhi yilokho i-chip ye-BCM2711 Akufinyelelanga emkhawulweni wayo, njengoba ikwazi ukubamba kuze kufike ku-16 GB wememori ye-LPDDR4 SDRAM. Ngakho-ke, asikho isithiyo somzimba ekungezeni okungaphezu kwe-4GB yememori. Inkinga ukuthi bekungekho i-chip chip yaleso sayizi nezimpawu ze-SBC kuze kube manje.
Kepha iRaspberry Pi Foundation isebenze nayo umlingani wezobuchwepheshe uMicron ukuthatha leso sinyathelo nokuthi i-chip yomthamo omkhulu ibingokoqobo. Umphumela wokugcina yile Raspberry Pi 4 Model B entsha ene-8GB, okusho ukuthi ngamanye amagama isafana naleyo edlule.
Izindaba ezethembisayo impela, ngoba i-8GB ye-SBC iyinani elibaluleke kakhulu. Uma sibona ukuthi imboni yamakhompyutha ivele kanjani umbono, siyabona ukuthi esikhathini esedlule lezi ziningi kumakhompyutha amakhulu bezicishe zingafinyeleleki, nokuthi manje sezingafakwa ku-chip eyodwa ebhodini elincane nelinamandla amancane.
Lokho Bill Gates, kucatshangwa ukuthi wayecabanga (i-apocryphal quote), ukuthi imemori engama-640 KB kufanele yanele kunoma ngubani ophelelwe yisikhathi. I-8GB imele izikhathi eziphindwe ka-13.000 ukwedlula leyo futhi ngeke yenele esikhathini esizayo esiseduze noma kuya ngokuthi yiziphi izicelo.
Ezinye izici ezintsha ze-Raspberry Pi 4 Model B 8GB
Uma ucabanga ukuthi i-RAM ukuphela kwento Yini eshintshile kule Raspberry Pi entsha, iqiniso ukuthi uyiphutha. Kuyiqiniso ukuthi izici eziningi zihlala zifana, kepha hhayi zonke ...
Umthamo owandisiwe we-RAM udinga ukupakishwa okusha, kanye ne- izingxenye ezintsha zokuphakelwa kwamandla ebhodini (switch, inductors ,, ...), into ebidinga izinyanga zomsebenzi nokuyakha kabusha, nokuthile ubhubhane lakwaSARS-CoV-2 olungakusizanga kahle ...
Futhi ama-64-bit?
Njengoba wazi, izithombe zezinhlelo zokusebenza ezisemthethweni ezisetshenziswa ngokuzenzakalela ku-Raspberry Pi 4 zisasebenzisa ama-32-bit, ngezandiso I-LPAE yenhlamvu, ivumela ukubhekana nenani elikhulu lememori njenge-64-bit yendabuko. Lokho kuvumela le nkumbulo enkulu ye-8GB yememori ukuthi yabelwe, ngomkhawulo inqubo eyodwa ebingakwazi ukusebenzisa ngaphezu kwe-3GB. Kubasebenzisi abaningi, lokhu akuyona into enhle, ikakhulukazi izinqubo ezisindayo ezifana ne-Chrome / Chromium lapho usebenzisa inani elikhulu lamawindi avulekile ngasikhathi sinye.
Kulabo basebenzisi abafuna ukusebenzisa isikhala esigcwele se-8GB kusuka kunqubo eyodwa, lapho-ke bayadinga ama-64-bit. Kubo sekuvele kunezinketho ezithakazelisa kakhulu njengoBuntu noma iGentoo.
Kepha ukukunikeza injabulo enkulu, kufanele wazi ukuthi iRaspberry Pi Foundation yethule i-Beta yesithombe sakho yezinhlelo zomdabu ezingama-64 zokusebenza. Ngakho-ke, ungazisebenzisa nale Rasbperry Pi 4 evuselelwe futhi ngaleyo ndlela ube nawo wonke amandla adingekayo. Lezi zithombe ezintsha zinegama elisha: Okusajingijolo Pi OS. Kuzofanele sinake kakhulu le ntuthuko entsha ...
Ngakho-ke, kusukela manje kuqhubeke, khohlwa igama lesiRaspbian, elalichaza isisekelo salo seDebian. Noma kunjalo, okusha Okusajingijolo Pi OS kususelwa kunguqulo ye-ARM ye-Debian. Akukho okushintshile, kepha bebefuna ukuyinika elinye igama.
Ungayithengaphi i-4GB Raspberry Pi 8 Model B
Ungakwazi thenga ibhodi lakho le-SBC manje I-raspberry Pi 4 Model B 8GB kusuka esitolo esisemthethweni sesisekelo. Ngokushesha izothunyelwa kwezinye izitolo. Izinketho okufanele uzitholele ipuleti lakho ziyahamba:
- Ngena ngaphakathi isitolo esisemthethweni.
- Khetha imodeli oyifunayo nezwe lakho.
- Thenga i- $ 75 (khumbula ukuthi nge-Covid-19 kungaba nokubambezeleka).
Uma ukhetha, futhi awudingi i-8GB, ungathenga ezinye izinhlobo ezinomthamo wememori ephansi we Intengo eshibhile. Isibonelo:
- Thenga i-Raspberry Pi 4 Model B 2GB
- Thenga i-Raspberry Pi 4 Model B 4GB
- Ikhithi yokufaka i-SBC yakhoIshaja ye-Aukru - 5V,...
- Ikhithi yokudlala ye-Retro
