Projet Raspberry Pi a annonc\u00e9<\/a><\/noindex> version \u00e9tendue de la carte Raspberry Pi 4, livr\u00e9e avec 8 Go de RAM. Le prix de la nouvelle version de la carte est<\/a><\/noindex> 75 $. \u00c0 titre de comparaison, les cartes avec 2 et 4 Go de RAM sont vendues respectivement 35 et 55 dollars. <\/p>\n

Le chipset BCM2711 utilis\u00e9 sur la carte permet d'adresser jusqu'\u00e0 16 Go de m\u00e9moire, mais lors du d\u00e9veloppement de la carte l'ann\u00e9e derni\u00e8re, les puces LPDDR4 SDRAM appropri\u00e9es n'\u00e9taient pas disponibles \u00e0 la vente. Maintenant, la soci\u00e9t\u00e9 Micron a sorti les puces n\u00e9cessaires avec 8 Go, sur la base desquelles est construite la nouvelle version de la Raspberry Pi 4. La fourniture de la puce LPDDR4 SDRAM 8 Go plus \u00e9nergivore a \u00e9galement n\u00e9cessit\u00e9 une l\u00e9g\u00e8re modernisation des circuits d'alimentation et le d\u00e9placement du convertisseur de tension de la zone \u00e0 proximit\u00e9 des ports USB 2.0 vers la zone \u00e0 proximit\u00e9 de l'USB-C.<\/p>\n

Rappelons que la carte Raspberry Pi 4 est \u00e9quip\u00e9e d'un SoC BCM2711 et comprend quatre c\u0153urs ARMv8 Cortex-A72 64 bits fonctionnant \u00e0 1,5 GHz, ainsi qu'un acc\u00e9l\u00e9rateur graphique VideoCore VI, qui prend en charge OpenGL ES 3.0 et peut d\u00e9coder des vid\u00e9os H.265 en qualit\u00e9 4Kp60 (ou 4Kp30 sur deux moniteurs). La carte est \u00e9quip\u00e9e de m\u00e9moire LPDDR4, d'un contr\u00f4leur PCI Express, d'Ethernet gigabit, de deux ports USB 3.0 (plus deux ports USB 2.0), de deux ports Micro HDMI (4K), d'un GPIO \u00e0 40 broches, de DSI (connexion de l'\u00e9cran tactile), de CSI (connexion de la cam\u00e9ra) et d'une puce sans fil prenant en charge la norme 802.11ac, fonctionnant aux fr\u00e9quences 2.4 GHz et 5 GHz, ainsi que Bluetooth 5.0. L'alimentation peut \u00eatre fournie via le port USB-C (USB micro-B \u00e9tait utilis\u00e9 auparavant), via GPIO ou via un module suppl\u00e9mentaire PoE HAT (Power over Ethernet). Les tests de performance montrent que la Raspberry Pi 4 bat la Raspberry Pi 3B+ par 2 \u00e0 4 fois, et la Raspberry Pi 1 par 40 fois.
