Projekt Raspberry Pi og\u0142osi\u0142<\/a><\/noindex> rozszerzon\u0105 wersj\u0119 p\u0142yty Raspberry Pi 4, dostarczan\u0105 z 8 GB RAM. Cena nowej wersji p\u0142yty wynosi<\/a><\/noindex> $75. Dla por\u00f3wnania p\u0142yty z 2 i 4 GB RAM sprzedawane s\u0105 za 35 i 55 dolar\u00f3w ameryka\u0144skich odpowiednio. <\/p>\n

U\u017cyty w p\u0142ycie chip BCM2711 pozwala na adresowanie do 16 GB pami\u0119ci, jednak w momencie projektowania p\u0142yty w ubieg\u0142ym roku na rynku brakowa\u0142o odpowiednich chip\u00f3w LPDDR4 SDRAM. Teraz firma Micron wypu\u015bci\u0142a niezb\u0119dne chipy z 8 GB, na kt\u00f3rych bazuje nowa wersja Raspberry Pi 4. Wprowadzenie bardziej energoch\u0142onnego chipu 8 GB LPDDR4 SDRAM wymaga\u0142o r\u00f3wnie\u017c niewielkiej modernizacji obwod\u00f3w zasilaj\u0105cych oraz przeniesienia przetwornika impulsowego z obszaru obok z\u0142\u0105cza USB 2.0 w okolice USB-C.<\/p>\n

Przypomnijmy, \u017ce p\u0142yta Raspberry Pi 4 jest wyposa\u017cona w SoC BCM2711 i zawiera cztery 64-bitowe rdzenie ARMv8 Cortex-A72, dzia\u0142aj\u0105ce z cz\u0119stotliwo\u015bci\u0105 1.5GHz, oraz procesor graficzny VideoCore VI, kt\u00f3ry obs\u0142uguje OpenGL ES 3.0 i potrafi dekodowa\u0107 wideo H.265 w jako\u015bci 4Kp60 (lub 4Kp30 na dwa monitory). P\u0142yta wyposa\u017cona jest w pami\u0119\u0107 LPDDR4, kontroler PCI Express, gigabitowy Ethernet, dwa porty USB 3.0 (plus dwa porty USB 2.0), dwa porty Micro HDMI (4K), 40-pinowe GPIO, DSI (z\u0142\u0105cze ekranowe), CSI (z\u0142\u0105cze kamery) oraz chip bezprzewodowy, obs\u0142uguj\u0105cy standard 802.11ac, dzia\u0142aj\u0105cy na cz\u0119stotliwo\u015bciach 2.4GHz i 5GHz oraz Bluetooth 5.0. Zasilanie mo\u017ce by\u0107 dostarczane przez port USB-C (wcze\u015bniej u\u017cywany USB micro-B), przez GPIO lub przez dodatkowy modu\u0142 PoE HAT (Power over Ethernet). W testach wydajno\u015bci Raspberry Pi 4 przewy\u017csza Raspberry Pi 3B+ od 2 do 4 razy, a Raspberry Pi 1 a\u017c 40 razy.
