Mais sous le capot, il y a certaines choses dont vous devez \u00eatre conscient. <\/p>\n\n\n\n\n\n<h2 class=\"wp-block-heading\" id=\"raspberry-pi-choose-32-or-64-bit\">Raspberry Pi : choisir 32 ou 64 bits ?<\/h2>\n\n\n\n<p>L'ordinateur que vous utilisez comme station de travail principale est tr\u00e8s probablement en 64 bits.<\/p>\n\n\n\n<p>Le mien l'est certainement.<\/p>\n\n\n\n<p>Donc, si la plupart des ordinateurs fonctionnent en 64 bits, la conclusion logique serait que le 64 bits est meilleur que le 32 bits, n'est-ce pas ?<\/p>\n\n\n\n<p>Permettez-moi de souligner ce que Raspberry Pi dit dans son article sur le nouveau syst\u00e8me d'exploitation : \"Faites-nous savoir dans les commentaires si...\". <strong>les avantages (ou les inconv\u00e9nients) de votre cas d'utilisation.<\/strong> du passage au 64 bits\".<\/p>\n\n\n\n<p>Donc oui, vous pouvez b\u00e9n\u00e9ficier ou souffrir de l'utilisation du nouveau Raspberry Pi OS 64 bit.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"benefits-of-the-new-raspberry-pi-os-64-bit\">Avantages du nouveau Raspberry Pi OS 64-bit<\/h3>\n\n\n\n<p><strong>Lib\u00e8re tout le potentiel des Pis les plus r\u00e9cents (en th\u00e9orie).<\/strong><\/p>\n\n\n\n<p>Dans ma pr\u00e9c\u00e9dente voiture, il y avait un limiteur de vitesse qui la r\u00e9gissait \u00e0 environ 210km\/h.<\/p>\n\n\n\n<p>Peut-\u00eatre que le moteur peut faire plus, mais le limiteur de vitesse ne le permet pas.<\/p>\n\n\n\n<p>Ainsi, pendant de nombreuses ann\u00e9es, les Raspberry Pis les plus r\u00e9cents \u00e9taient dot\u00e9s d'un processeur beaucoup plus puissant qui fonctionnait dans un environnement aux performances restreintes, \u00e0 savoir le 32 bits.<\/p>\n\n\n\n<p>La principale raison est d'ordre pratique : un syst\u00e8me d'exploitation 32 bits fonctionnerait sur tous leurs appareils, tandis qu'un syst\u00e8me d'exploitation 64 bits les obligerait \u00e0 maintenir deux syst\u00e8mes d'exploitation et pourrait entra\u00eener une confusion chez les clients.<\/p>\n\n\n\n<p>Donc, le 64 bits va absolument d\u00e9cha\u00eener la b\u00eate, non ?<\/p>\n\n\n\n<p>Th\u00e9oriquement, vous devriez constater une augmentation des performances simplement en passant \u00e0 un environnement 64 bits, et les avantages s'accumulent vraiment sur le Raspberry Pi 4 de 8 Go. <\/p>\n\n\n\n<p>Auparavant, le syst\u00e8me d'exploitation Raspberry Pi utilisait l'extension ARM Large Physical Address Extension pour acc\u00e9der jusqu'\u00e0 8 Go de m\u00e9moire, ce qui avait pour limite d'allouer \u00e0 chaque processus un maximum de 3 Go. Avec le nouveau syst\u00e8me d'exploitation 64 bits, un seul processus peut occuper la totalit\u00e9 des 8 Go. <\/p>\n\n\n\n<p>Les v\u00e9ritables avantages reviendront aux utilisateurs qui se servent de leurs Raspberry Pis comme serveurs, h\u00f4tes Docker ou Kubernetes et autres utilisations \u00e0 haute intensit\u00e9 comme l'encodage vid\u00e9o.<\/p>\n\n\n\n<p>Peut-\u00eatre devrions-nous \u00e9galement noter que la version b\u00eata du Raspberry Pi OS 64 bits est sortie au m\u00eame moment que la sortie du Pi 4 de 8 Go (mai 2020).<\/p>\n\n\n\n<p>Alors pourquoi je dis que ces avantages ne sont que \"th\u00e9oriques\" ? Eh bien, il s'agit simplement des autres goulets d'\u00e9tranglement. <\/p>\n\n\n\n<p>Si le programme que vous utilisez souvent ne dispose pas d'une version 64 bits, vous n'en tirerez que peu d'avantages car vous devrez toujours utiliser la version 32 bits (par exemple, si vous souhaitez utiliser Chromium pour diffuser Netflix ou d'autres contenus DRM).<\/p>\n\n\n\n<p>J'ai \u00e9galement test\u00e9 un Raspberry Pi Zero 2 avec le syst\u00e8me d'exploitation 32 et 64 bits et les temps de chargement de PiCockpit.com n'ont pas chang\u00e9.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"what-do-the-32-bit-vs-64-bit-raspberry-pi-benchmarks-say\">Que disent les benchmarks 32-bit vs 64-bit Raspberry Pi ?<\/h3>\n\n\n\n<p>A <a href=\"https:\/\/openbenchmarking.org\/result\/2202058-NE-RASPBERRY79&amp;sgm=1\" rel=\"nofollow\">\u00e9tude comparative<\/a> a montr\u00e9 que le Raspberry Pi OS 64 bits est plus rapide que le 32 bits dans tous les tests sauf un.<\/p>\n\n\n\n<p>Michael Larabel l'a test\u00e9 sur un Raspberry Pi 400 de 4 Go et ses r\u00e9sultats montrent qu'en mati\u00e8re de manipulation graphique, d'intelligence artificielle, d'encodage audio, de stress, de compression et bien d'autres tests, le syst\u00e8me d'exploitation 64 bits s'est av\u00e9r\u00e9 largement sup\u00e9rieur.<\/p>\n\n\n\n<p>Sa conclusion est que vous constaterez une am\u00e9lioration moyenne de 48% des performances en faisant exactement la m\u00eame chose sur le syst\u00e8me d'exploitation 64 bits.<\/p>\n\n\n\n<p><strong>Ex\u00e9cuter des programmes 64 bits<\/strong><\/p>\n\n\n\n<p>Un autre avantage de l'utilisation d'un syst\u00e8me d'exploitation 64 bits sur le Raspberry Pi serait d'ex\u00e9cuter des programmes que vous ne pourriez pas ex\u00e9cuter sur l'\u00e9quivalent 32 bits. Par exemple, certains programmes \u00e0 code ferm\u00e9 ne sont disponibles que pour arm64 et m\u00eame les logiciels qui fonctionnent sur armhf ne sont pas n\u00e9cessairement optimis\u00e9s pour lui.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"downsides-of-using-the-64-bit-raspberry-pi-os\">Inconv\u00e9nients de l'utilisation du syst\u00e8me d'exploitation 64 bits de Raspberry Pi<\/h3>\n\n\n\n<p><strong>Soutien limit\u00e9 pour la gamme Pi<\/strong><\/p>\n\n\n\n<p>L'une des meilleures choses \u00e0 propos de l'utilisation d'un Raspberry Pi est que vous pouvez prendre une carte SD (avec un syst\u00e8me d'exploitation Raspberry Pi install\u00e9) d'un Pi et la placer dans un autre. Tout fonctionnera parfaitement. <\/p>\n\n\n\n<p>Maintenant, avec le Raspberry Pi 64 bits, vous ne serez pas en mesure de faire ce changement de carte SD sur les anciens Pis (1, 2 et Zero). C'est donc un inconv\u00e9nient imm\u00e9diat. Un exemple o\u00f9 ce serait un inconv\u00e9nient concerne le Zero. Dans le pass\u00e9, vous pouviez simplement faire votre installation, votre programmation, etc. sur le Pi 4 et ensuite le transf\u00e9rer sur le Zero. Mais si vous utilisez un syst\u00e8me d'exploitation 64 bits sur le Pi 4, vous ne pouvez pas utiliser cette carte SD sur la Zero (mais vous pouvez le faire sur la Zero 2 W).<\/p>\n\n\n\n<p><strong>Non \"test\u00e9 au combat\" (c'est-\u00e0-dire qu'il pourrait y avoir des bogues)<\/strong><\/p>\n\n\n\n<p>Le nouveau Raspberry Pi OS 64 bits ne b\u00e9n\u00e9ficie pas du m\u00eame temps de test que son homologue 32 bits, il faudra donc un certain temps avant qu'il n'atteigne ce stade.<\/p>\n\n\n\n<p>Vous pouvez vous attendre \u00e0 des bogues qui n'existent pas sur le 32 bits, et certains d'entre eux resteront non r\u00e9solus jusqu'\u00e0 ce que la base d'utilisateurs les rattrape. En d'autres termes, un correctif qui fonctionne sur le syst\u00e8me 32 bits peut ne pas fonctionner sur le syst\u00e8me 64 bits.<\/p>\n\n\n\n<p>C'est le cas de Chromium. Oui, il existe une version 64 bits de Chromium mais vous ne pouvez pas lire les m\u00e9dias en streaming tels que Netflix ou Disney+ car elle ne dispose pas de la biblioth\u00e8que WidevineCDM (pour la protection DRM). Si c'est votre cas d'utilisation, Raspberry Pi vous recommande d'installer la version 32 bits dans le Terminal en utilisant cette commande :<\/p>\n\n\n\n<div
