La Raspberry Pi 4 inogadziridzwa, uye ikozvino inodarika muganho we4GB yakatemwa mushanduro dzapfuura dzeModel B yeSBC iyi. Iye zvino unogona kutenga iyo Rasbperry Pi 4 Model B 8 GB pamutengo unenge madhora makumi manomwe neshanu. Iyo inokatyamadza yakakosha memory memory iyo iyo inokutendera iwe kumhanyisa mamwe maitiro nekukurumidza.
Rinenge gore mushure mekutanga Raspberry Pi 4, iro rakasimba basa revagadziri varo rinodzoka kuzopa mhedzisiro yekugutsa vashandisi vanonyanya kuda. Iyo Pi 4 yatove kubudirira, iine mamirioni matatu mauniti akatengeswa, mune yayo 3GB, 1GB uye 2GB shanduro. Ichokwadi kuti chitsva SBC ine 8 GB ichabatsira iyo nhamba kuramba ichikura.
Basa rakanangana nekuderedza nyika dzisina basa nekuvandudza mashandiro nemitoro yemabasa, pamwe nekutangisa neine simba Vulkan graphical API, PXE network boot mode, pamwe nekugadzirisa zviputi, nezvimwe. Ivo zvino vafara nezve kuburitswa kweiyi imwe 8GB RAM vhezheni. kune vanofarira vasina kugutsikana nezvakatove nazvo.
Uye ndizvo izvozvo iyo BCM2711 chip Haisati yasvika muganho wayo, sezvo ichigona kutarisa kusvika ku16 GB yeLPDDR4 SDRAM ndangariro. Naizvozvo, hapana chipingamupinyi chemuviri pakuwedzera kwete anopfuura 4GB yekurangarira. Dambudziko raive rekuti pakanga pasina memory chip yeiyo saizi uye hunhu hweiyo SBC kusvika zvino.
Asi iyo Raspberry Pi Foundation yakashanda pamwe neayo tekinoroji mudiwa Micron kutora danho iro uye kuti chip yehukuru hukuru chaive chaicho. Mhedzisiro mhedzisiro iyi nyowani Raspberry Pi 4 Model B ine 8GB, iyo mune mamwe mazwi ichiri yakafanana neiyo yapfuura.
Nhau dzinovimbisa zvikuru, sezvo 8GB yeSBC iri yakawanda kwazvo mari. Kana isu tichiona mashandisiro emakomputa indasitiri maonero, tinoona kuti munguva yakapfuura huwandu uhwu mumakomputa mahombe hwaive husingawanikwe, uye kuti izvozvi dzinogona kuiswa mune imwechete chip pane yakadaro diki uye yakaderera-simba bhodhi.
Izvo izvo Bill Gates, achifungidzirwa kuti akafunga (apocryphal quote), kuti 640 KB yekurangarira inofanirwa kukwana kune chero munhu abuda munzira. Iyo 8GB inomiririra ka13.000 zvakapetwa kupfuura izvozvo uye haizokwani munguva pfupi iri kutevera kana zvichienderana nezvinoshandiswa.
Zvimwe zvinhu zvitsva zveiyo 4GB Raspberry Pi 8 Model B
Kana iwe uchifunga kuti RAM ndicho chete chinhu Chii zvachinja mune ino nyowani Raspberry Pi, chokwadi ndechekuti iwe wakanganisa. Ichokwadi kuti maitiro mazhinji anoramba akafanana, asi kwete ese ...
Iyo yakawedzera kugona kweiyo RAM inoda nyowani yekupakata, pamwe ne nyowani zvinhu zvekushandisa magetsi pabhodhi (switch, inductors, ...), chimwe chinhu chakada mwedzi yekushanda nekugadzirisa, uye chimwe chinhu icho chirwere cheSARS-CoV-2 hachina kunyatso kubatsira ...
Uye iyo 64-bit?
Sezvaunoziva, iyo mifananidzo yemahofisi anoshanda masisitimu ayo anoshandiswa nekumisikidza muRaspberry Pi 4 achiri kushandisa 32-bit, iine ekuwedzera LPAE yeiyo tsanga, ichibvumira kugadzirisa huwandu hwakawanda hwekurangarira seyazvarwa 64-bit. Izvo zvinobvumidza iyi hombe 8GB yekurangarira kuti igoverwe, iine muganho wekuti imwe nzira yaisagona kushandisa inopfuura 3GB. Kune vashandisi vazhinji, ichi hachisi chinhu chakanaka, kunyanya kune zvinorema maitiro senge Chrome / Chromium kana uchishandisa akawanda akavhura windows panguva imwe chete.
Kune avo vashandisi vanoda kushandisa izere 8GB nzvimbo kubva kune imwechete maitiro, saka ivo vanoda iyo 64-bit. Kwavari pane atove anonakidza sarudzo senge Ubuntu kana Gentoo.
Asi kuti ndikupe iwe wakanyanya mufaro, iwe unofanirwa kuziva kuti iyo Raspberry Pi Foundation yakavhura iyo Beta yemufananidzo wako yezvizvarwa 64-bit masisitimu anoshanda. Naizvozvo, iwe unogona kuvashandisa neiyi yakavandudzwa Rasbperry Pi 4 uye nekudaro uine simba rese rinodiwa. Iyi mifananidzo mitsva ine zita idzva: Raspberry Pi OS. Tichafanirwa kunyatsoteerera kuvandudzwa uku kutsva ...
Saka, kubva zvino zvichienda mberi, kanganwa zita reRaspbian, iro raireva kune yayo Debian base. Nekudaro, iyo nyowani Raspberry Pi OS ichiri kubva pane iyo ARM vhezheni yeDebian. Hapana chakachinja, asi ivo vaida kuchipa iri rimwe zita.
Kwokutenga iyo 4GB Raspberry Pi 8 Model B
Unogona tenga bhodhi rako reSBC izvozvi Rasipberry Pi 4 Model B 8GB kubva pahofisi yechitoro chepamutemo. Ichakurumidza kuburitsirwa kune zvimwe zvitoro. Sarudzo dzaunofanirwa kutora yako ndiro dzinopfuura:
- Pinda mukati chitoro chepamutemo.
- Sarudza modhi yaunoda nenyika yako.
- Gadzira yako kutenga ye $ 75 (ramba uchifunga kuti neCovid-19 panogona kuve nekunonoka).
Kana iwe uchida, uye iwe usingade 8GB, unogona kutenga mamwe mavhezheni ane yakaderera ndangariro kugona kwe isingadhuri mutengo. Somuenzaniso:
