Raspberry Pi 4 kana Raspberry Pi 3B+, ndeipi iri nani?

Uri kufunga kutenga Raspberry Pi asi uzviwane wabvaruka pakati peazvino mhando? Neiyo Raspberry Pi ecosystem inoramba ichiwedzera, kusarudza iyo chaiyo modhi inogona kunetsa. Sarudzo mbiri dzakakurumbira, iyo Raspberry Pi 4 uye iyo Raspberry Pi 3B +, inopa akasiyana maficha uye nhanho dzekuita, inotarisira kune zvakasiyana siyana. Mukuenzanisa uku, tichaongorora misiyano yakakosha pakati pemhando idzi kuti tikubatsire kuita sarudzo ine ruzivo.

Raspberry Pi 4 vs Raspberry PI 3B+: CPU, RAM, uye Graphics

Kana zvasvika pakugadzirisa simba, RAM, uye magiraidhi kugona, mutsauko uripo pakati peRaspberry Pi 4 uye Raspberry Pi 3B + unooneka. Iyo Raspberry Pi 4 inozvirumbidza nequad-core ARM Cortex-A72 CPU inomhanya pa1.5 GHz, iri nhanho kubva kuRaspberry Pi 3B+'s quad-core ARM Cortex-A53 CPU pa1.4 GHz. Musiyano uyu unoguma nekuvandudzwa kwakanyanya kwekuita kwekombuta-yakanyanya maapplication.

Panyaya yendangariro, iyo Raspberry Pi 4 inopa sarudzo ne2GB, 4GB, kana 8GB LPDDR4 SDRAM, ichipa vashandisi kuchinjika uye mukana wekuita zvakawanda uye kubata mamwe mabasa akaomarara. Iyo Raspberry Pi 3B +, kune rumwe rutivi, inongogumira ku1GB LPDDR2 SDRAM, iyo inogona kunge ichiganhurira kune mamwe mabasa anodiwa.

Kana ari magiraidhi, Raspberry Pi 4 inoenda kumberi neVideoCore VI graphics processor inotsigira OpenGL ES 3.x. Izvi zvinobvumira kubata zvirinani zvemazuva ano graphical application uye mabasa, chimwe chinhu icho Raspberry Pi 3B+ neVideoCore IV graphics processor inotsigira OpenGL ES 2.0 inogona kunetseka nayo. Kufambira mberi uku kunovhura mikana mitsva yevashandisi vari kutsvaga kushanda nepamusoro-inoshanda graphical kubuda.

Performance Benchmarks: Raspberry Pi 3B+ vs Raspberry Pi 4

Mumusoro-kune-musoro bhenji bvunzo, iyo Raspberry Pi 4 inogara ichipfuura iyo Raspberry Pi 3B+. Nekukurumidza kuita kweCPU, sezvinoratidzwa nemabhenji maturusi seSysbench, kune epamusoro magiraidhi anobata nekutenda kune yayo yepamusoro GPU, iyo Raspberry Pi 4 ndiye mutungamiri akajeka maererano nemasimba emagetsi.

Kana zvasvika kune chaiyo-yepasirese application, vashandisi vanozoona kuti iyo Raspberry Pi 4 inobata mabasa akaomarara akadai sevhidhiyo kugadzirisa uye computation zvakanyanya kunyatsoita. Kuita kwemitambo kunoratidzawo kuvandudzwa kunooneka, nerutsigiro rwemamwe mazuvano OpenGL mazinga achivhura musuwo webudiriro yeramangwana muRaspberry Pi mutambo wekutamba.

Kusvetuka kukuru mukuita kunoonekwa mukukwanisa kweRaspberry Pi 4 kuverenga nekunyora data kune ekunze USB madhiraivha, iine USB 3.0 ports inopa kumhanya kwekufambisa kwakanyanya kupfuura USB 2.0 ports inowanikwa paRaspberry Pi 3B+. Iyi yekusimudzira yega inoshandura mutambo kune vashandisi vanoda kukurumidza kugadzirisa data uye kutamiswa.

Kuwedzeredza Kwekubatanidza: Ports uye Wireless Kugona

Raspberry Pi 4 ine nzira dzakawanda dzekuvandudza kubatana kupfuura yekare. Nekuwedzera ma USB 3.0 ports maviri, vashandisi vachaona kumhanya kwakanyanya kwekutumira data kune zvishandiso zvakabatana. Kubatana kwe wireless kunoonawo kuvandudzwa nekubatanidzwa kweBluetooth 5.0, ichipa huwandu hwakareba uye huwandu hwekutumira data nekukurumidza kupfuura Bluetooth 4.2 inowanikwa paRaspberry Pi 3B+.

Uyezve, Raspberry Pi 4 inounza maports maviri eHDMI , achitsigira resolution ye4K pane imwe port, nokudaro zvichigonesa kushandiswa kwema multi-monitor setups - kuvandudzika kukuru pane imwe chete 1080p output yeRaspberry Pi 3B+.

Simba Zvinodiwa uye Thermal Management

Zvinodiwa pamagetsi uye kutarisirwa kwekupisa zvinhu zvakakosha pakusarudza pakati peRaspberry Pi 4 neRaspberry Pi 3B+. Hardware yakagadziridzwa yeRaspberry Pi 4 inoda simba rakasimba, rinokwanisa kupa kanenge 3A, zvichienzaniswa neRaspberry Pi 3B+ iyo inogona kushanda pasimba remagetsi re5V / 2A.

Iyo yakawedzera simba inodiwa yeRaspberry Pi 4 inoguma nepamusoro mashandisiro emagetsi uye kupisa kugadzirwa. Kudzivirira kupisa uye kukuvadza kubhodhi, vashandisi vanofanirwa kufunga nezvekudyara mune mamwe ekutonhodza mhinduro senge heatsinks uye mafeni. Izvi zvishongedzo zvinobatsira kubvisa kupisa zvakanyanya, kuve nechokwadi chekuita kwakagadzikana uye hupenyu hurefu hweRaspberry Pi 4.

Paunenge uchisarudza magetsi eiyo Raspberry Pi 4, zvakakosha kuti usarudze imwe inosangana nezvinokurudzirwa kuti udzivise nyaya dzine chekuita nekusakwana kwemagetsi kuendesa. Pamusoro pezvo, kugara uchitarisisa tembiricha yebhodhi inokurudzirwa, kunyanya panguva yekushandiswa kwakanyanya, kuve nechokwadi chekuita kwakanyanya uye kudzivirira kupisa.

Muchidimbu, iyo Raspberry Pi 4's yakawedzera simba zvinodiwa uye zvinodziya manejimendi zvinodiwa zvinofanirwa kuverengerwa kana uchifunga kukodzera kwayo kwepurojekiti yako. Magetsi akakodzera uye zvigadziriso zvekutonhora zvakakosha kuti uve nechokwadi chekushanda kwakagadzikana uye hupenyu hurefu hwechishandiso.

Mhedziso uye Maitiro ekuita Sarudzo

Paunenge uchifunga pakati peRaspberry Pi 4 neRaspberry Pi 3B+, zvakakosha kuti utarise zvinodiwa zvepurojekiti yako chaiyo. Iwo epamberi maficha eRaspberry Pi 4 anogona kunge ari madikanwa kune akanyanya-kudiwa mabasa uye avo vari kutsvaga kuita kwakanyanya kunowanikwa paRaspberry Pi papuratifomu. Nekudaro, iyo Raspberry Pi 3B + inoramba iri yakakosha sarudzo yemapurojekiti ane zvakawanda zvine mwero zvinodiwa uye zvirambidzo zvebhajeti.

Izvo zvakakosha kuti uongorore zvinodikanwa zvechikumbiro chako, kusanganisira kumhanya kwekugadzirisa, magirafu anodiwa, sarudzo dzekubatanidza, mashandisiro emagetsi, uye zvimhingamipinyi zvebhajeti, kuita sarudzo ine ruzivo pamusoro peiyo Raspberry Pi modhi yekusarudza. Mamodheru ese ari maviri anoenderera mberi nekuwedzera iyo Raspberry Pi ecosystem, ichipa vashandisi huwandu hwakawanda hwesarudzo dzakagadzirirwa kune yavo yakasarudzika purojekiti zvavanoda.
