Il prezzo della nuova versione della scheda <noindex><a rel=\"nofollow\" href=\"https:\/\/www.raspberrypi.org\/products\/raspberry-pi-4-model-b\/\">\u00e8<\/a><\/noindex> $75. A titolo di confronto, le schede con 2 e 4 GB di RAM sono vendute rispettivamente a 35 e 55 dollari. <\/p>\n<p>Il chip BCM2711 utilizzato sulla scheda consente di indirizzare fino a 16 GB di memoria, ma al momento dello sviluppo della scheda lo scorso anno non erano disponibili chip LPDDR4 SDRAM adeguati. Ora, la Micron ha rilasciato i chip necessari da 8 GB, su cui si basa la nuova versione del Raspberry Pi 4. L'arrivo di un chip 8 GB LPDDR4 SDRAM pi\u00f9 energivoro ha anche richiesto una leggera modernizzazione dei circuiti di alimentazione e lo spostamento del convertitore a impulsi dall'area vicino alle porte USB 2.0 a quella vicino a USB-C.<\/p>\n<p>Ricordiamo che la scheda Raspberry Pi 4 \u00e8 dotata di SoC BCM2711 e include quattro core ARMv8 Cortex-A72 a 64 bit che funzionano a una frequenza di 1.5 GHz, e un acceleratore grafico VideoCore VI, che supporta OpenGL ES 3.0 e pu\u00f2 decodificare video H.265 con qualit\u00e0 4Kp60 (o 4Kp30 su due monitor). La scheda \u00e8 dotata di memoria LPDDR4, di un controller PCI Express, di Ethernet gigabit, di due porte USB 3.0 (oltre a due porte USB 2.0), di due porte Micro HDMI (4K), di 40 pin GPIO, DSI (connessione touchscreen), CSI (connessione fotocamera) e di un chip wireless che supporta lo standard 802.11ac, operando a frequenze di 2.4 GHz e 5 GHz e Bluetooth 5.0. L'alimentazione pu\u00f2 essere fornita tramite la porta USB-C (precedentemente si usava USB micro-B), tramite GPIO o tramite un modulo PoE HAT (Power over Ethernet). Nei test di prestazioni, il Raspberry Pi 4 supera il Raspberry Pi 3B+ di 2-4 volte e il Raspberry Pi 1 di 40 volte.<br \/>\n<center><noindex><a rel=\"nofollow\"
