Ce petit tuto reprend les étapes d'installation du pilote openCL sur ces matériels et système :
le tout , fait sur linux debian testing bullseye / debian bookworm sid et avec
Un grand merci à PLOP6 via (irc) sans qui rien de ce tuto n'aurait été possible.
Le pilote OpenCL, a été créé pour uniformiser “massivement” les programmes de calculs parallèles2).
Au départ , son emploi s'étendait aussi bien aux calculs fait par les CPU que ceux faits par les GPU, possibilité que l'on retrouve aujourd'hui dans Blender.
Avec la commande cd, se positionner dans le répertoire Téléchargements
ainsi :
cd ~/Téléchargements/

de votre Debian.Pour les RX 500 , les pilotes OpenCL sont normalement fonctionnels sur debian 10 (buster, sûr) et 11 (bullseye , normalement) . Mais je vous conseille plutôt d'utiliser les derniers pilotes OpenCL (RX6000).
Créer les scripts suivants :
copiez/collez chacun des blocs ci-dessous et lancez-les indépendamment en user, chacun d'eux créera son fichier dans “ ~/Téléchargements/ ”

un script git qui télécharge amdgpu-pro et installe OpenCL et Vulkan .
actuellement la version 21.30 du 04/08/2021 pour ubuntu 20.04.3 LTS . fonctionne, en théorie , pour RX 5000 ET RX 6000 . prise en charge du noyau 5.11 .

Blender , depuis la version 3.1.2 , n'est plus disponible que en deb(défectueux sur ma distribution) , en flatpak (que j'ai utilisé) ou en snap .
qui plus est , il n'utilise plus openCL mais le pilote habituel , openGL . Désormais , ne sont disponibles dans Blender que les options CUDA et Optix .
la carte (RX 550) est montée en pointe , à 75 °C , au maxi une conso de 22 watts et un ventilo de 1300 RPM .
la RX 570 , elle , est montée , en pointe à 66 °C , conso maxi 100 watts et un ventilo à 1900 Tr/Min .
la RX 6800 est montée , en pointe , à 71 °C . conso maxi environ 220 watts .
voici quelques écrans que vous obtiendrez peut être à la fin de l'installation :

-19.50 (RX 550) ,
