Det finns nu en ny version av Raspberry Pi 4 Model B. Den h\u00e4r kostar mindre \u00e4n den vanliga SBC-varianten, men den \u00e4r inte helt identisk. Mer specifikt har den ett \u201dbinned\u201d chipset, som k\u00f6rs l\u00e5ngsammare \u00e4n processorn i standardutg\u00e5van.<\/p>\n
Som Cytron, \u00e5terf\u00f6rs\u00e4ljaren som erbjuder den prisv\u00e4rda Raspberry Pi 4 Model B, p\u00e5pekar, k\u00f6rs Broadcom BCM2711 i denna prisv\u00e4rda SBC med 1,25 GHz. F\u00f6r att se tillbaka: den ursprungliga varianten, som lanserades 2019<\/a>, hade en CPU med en klockfrekvens p\u00e5 1,5 GHz, men med en programuppdatering<\/a>fick den st\u00f6d f\u00f6r en klockfrekvens p\u00e5 1,8 GHz.<\/p>\n \u00c5terf\u00f6rs\u00e4ljaren framh\u00e5ller vidare att dessa sorterade Pi 4 Model B-enheter kommer direkt fr\u00e5n Raspberry Pi, men att de \u201dinte uppfyller specifikationerna f\u00f6r den maximala klockfrekvensen p\u00e5 1,8 GHz\u201d. Ist\u00e4llet s\u00e4gs de fungera \u201dfelfritt\u201d med CPU-frekvensen inst\u00e4lld p\u00e5 upp till \u201d1,25 GHz\u201d.<\/p>\n Denna s\u00e4nkning av klockfrekvensen b\u00f6r inte utg\u00f6ra n\u00e5got st\u00f6rre problem f\u00f6r de flesta till\u00e4mpningar. Om n\u00e5got skulle de sorterade Pi 4 Model B-enheterna vara n\u00e5got l\u00e5ngsammare \u00e4n standardenheten. Naturligtvis kan det finnas en m\u00e4rkbar skillnad i prestandatester och vid tunga arbetsbelastningar (GeeekPi-kylfl\u00e4ns i aluminium f\u00f6r SBC, f\u00f6r n\u00e4rvarande 11,99 dollar p\u00e5 Amazon<\/a>).<\/p>\n N\u00e4r det g\u00e4ller hur prisv\u00e4rd den sorterade versionen \u00e4r finns det tv\u00e5 konfigurationer tillg\u00e4ngliga, och den med 4 GB RAM kostar 87,25 dollar<\/a>. Som j\u00e4mf\u00f6relse kostar den vanliga SBC:n med samma minne 110 $ hos Cytron<\/a>, medan konfigurationen med 8 GB kostar 181,50 $.<\/p>\n Den sorterade 8 GB-versionen kostar d\u00e4remot 147 dollar. Dessa nyligen lanserade konfigurationer skulle allts\u00e5 vara bra val f\u00f6r projekt med mycket sn\u00e4va budgetar.<\/p>\n","protected":false},"excerpt":{"rendered":"Det finns nu en ny version av Raspberry Pi 4 Model B.
