La Raspberry Pi 4 iyahlaziywa, kwaye ngoku idlula umda we-4GB ebekwe kwiinguqulelo zangaphambili zeModeli B yale SBC. Ngoku ungathenga iRasbperry Pi 4 Model B 8 GB ngexabiso elimalunga ne- $ 75. Eyona nto ibalulekileyo kwimemori eyokuvumela ukuba uqhubeke ngakumbi neenkqubo ngakumbi.
Phantse unyaka emva kokuba i-Raspberry Pi 4 isungulwe, umsebenzi onzima wabaphuhlisi bayo ubuyela ukunika iziphumo ukwanelisa abasebenzisi abafuna kakhulu. Sele iPi 4 iyimpumelelo, malunga neeyunithi ezizizigidi ezi-3 ezithengisiweyo, kwiinguqulelo zayo ze-1GB, 2GB kunye ne4GB. Ngokuqinisekileyo intsha I-SBC ene-8 GB iya kunceda elo nani liqhubeke nokukhula.
Umsebenzi ugxile ekunciphiseni amazwe angasebenziyo kunye nokuphucula ukusetyenziswa kwemithwalo yomsebenzi, kunye nokuqala ngeVulkan graphical API enamandla, imowudi ye-PXE yenethiwekhi, kunye nokulungiswa kwe-bug, njl. Ngoku bonwabile malunga nokukhutshwa kwale nguqulo ye-8GB ye-RAM. kubathandi abangonelisekanga zizinto ebesele zinazo.
Kwaye oko i-chip ye-BCM2711 Ayikafikeleli kumda wayo, njengoko inokudibanisa ukuya kuthi ga kwi-16 GB yememori ye-LPDDR4 SDRAM. Ke ngoko, akukho sithintelo somzimba sokwengeza ngaphezulu kwe-4GB yememori. Ingxaki yayikukuba kwakungekho chip yememori yelo sayizi kunye neempawu ze-SBC kude kube ngoku.
Kodwa iRaspberry Pi Foundation isebenze nayo iqabane lobuchwepheshe uMicron ukuthatha elo nyathelo kwaye i-chip yesikhundla esikhulu yayinyani. Iziphumo zoku kukuba le Raspberry Pi 4 imodeli B intsha ine-8GB, ngamanye amagama isafana naleyo yangaphambili.
Zithembisa iindaba, kuba i-8GB ye-SBC sisixa esikhulu kakhulu. Ukuba sibona indlela ishishini lekhompyuter eliguquke ngayo nembono, siyabona ukuba ngaphambili ezi zinto zininzi kwiikhompyuter ezinkulu beziphantse zingafikeleleki, kwaye ngoku zinokufakwa kwichip enye kwibhodi encinci kunye namandla aphantsi.
Oko IBill Bill, kucingelwa ukuba wayecinga (isicatshulwa esingaphefumlelwanga), ukuba imemori engama-640 KB kufuneka yanele kuye nabani na ophume kumhla. I-8GB imele amaxesha ayi-13.000 ngaphezulu kunoko kwaye ayizukwanela kwixesha elizayo okanye ngokuxhomekeke kweziphi izicelo.
Olunye uhlobo olutsha lwe-4GB Raspberry Pi 8 Model B
Ukuba ucinga i-RAM kuphela kwento Yintoni etshintshileyo kule Raspberry Pi intsha, inyani kukuba uyaphazama. Kuyinyani ukuba uninzi lweempawu zihlala zinjalo, kodwa ayizizo zonke ...
Ukwanda komthamo we-RAM kufuna ukupakishwa okutsha, kunye ne izinto ezintsha zonikezelo lwamandla ebhodini (switch, inductors ...
Kwaye i-64-bit?
Njengoko uyazi, imifanekiso yeenkqubo zokusebenza ezisemthethweni ezisetyenziswa ngokungagqibekanga kwi-Raspberry Pi 4 zisasebenzisa i-32-bit, kunye nezandiso I-LPAE yekernel, Ukuvumela ukujongana nenani elikhulu lememori njenge-bit-64 yemveli. Oko kuvumela le 8GB enkulu yememori ukuba yabelwe, kunye nomda wokuba inkqubo enye ayinakho ukusebenzisa ngaphezulu kwe-3GB. Kubasebenzisi abaninzi, le ayisiyonto intle, ngakumbi kwiinkqubo ezinzima njengeChannel / Chromium xa usebenzisa inani elikhulu leefestile ezivulekileyo ngaxeshanye.
Kulabo basebenzisi abafuna ukusebenzisa indawo epheleleyo ye-8GB ukusuka kwinkqubo enye, emva koko bafuna amasuntswana angama-64. Kubo sele kukho ukhetho olunomdla kakhulu njengoBuntu okanye uGentoo.
Kodwa ukukunika uvuyo olukhulu, kuya kufuneka wazi ukuba iRaspberry Pi Foundation isungule I-Beta yomfanekiso wakho kwiinkqubo ezisebenza ngokwendalo ezingama-64. Ke ngoko, unokuzisebenzisa kunye nale Rasbperry Pi 4 ehlaziyiweyo kwaye ke unamandla onke afanelekileyo. Le mifanekiso mitsha inegama elitsha: I-Raspberry Pi OS. Kuya kufuneka siluqwalasele olu phuhliso lutsha ...
Ke, ukusukela ngoku ukuya phambili, ulibale igama laseRaspbian, elibhekisa kwisiseko seDebian. Nangona kunjalo, entsha I-Raspberry Pi OS isekwe kuhlobo lwe-ARM lweDebian. Akukho nto itshintshileyo, kodwa bafuna ukuyinika elinye igama.
Kuphi ukuthenga i-4GB Raspberry Pi 8 Umzekelo B
Unako thenga ibhodi yakho ye-SBC ngoku Raspberry Pi 4 Umzekelo B I-8GB ukusuka kwivenkile esemthethweni yesiseko. Iza kukhutshwa kwezinye iivenkile kungekudala. Izinketho onokuthi ufumane iplate yakho zihamba:
- Ngena ngaphakathi ivenkile esemthethweni.
- Khetha imodeli oyifunayo kunye nelizwe lakho.
- Yenza ukuthengwa kwakho nge- $ 75 (gcinani engqondweni ukuba nge-Covid-19 kunokubakho ukulibaziseka).
Ukuba ukhetha, kwaye awudingi i-8GB, ungathenga ezinye iinguqulelo ezinomthamo wememori esezantsi ngexabiso eliphantsi. Umzekelo:
- Thenga iRaspberry Pi 4 Imodeli B 2GB
- Thenga iRaspberry Pi 4 Imodeli B 4GB
- Ikhithi yokufaka i-SBC yakhoI-Aukru-5V itshaja,...
- Ikhithi yokudlala yeRetro
