Performance CPU/RAM

HardKernel à réalisé plusieurs banc d'essais (benchmarks) pour mesurer la puissance de traitement du XU4. Les mêmes tests ont étés réalisés sur un Rapsberry-Pi 2 Modèle B, ODROID-C1, ODROID-U3 et ODROID-XU4.

Les valeurs des différents test ont étés mis-à-l'échelle pour permettre une comparaison unforme. La puissance de traitement d'un XU4 à été mesuré comme étant 3 à 4 fois plus rapide que le Raspberry Pi 2 (grâce aux coeurs Cortex-A15 à 2Ghz et à la plus grande bande passante de la mémoire). Avec le XU4, vous pouvez créer un nano ordinateur offrant une expérience "bureaux PC" confortable par rapport aux autres ordinateurs mono-carte!

Plus particulièrement, les développeurs apprécierons les performances 3 à 4 fois supérieurs lors de phase de compilation. La haute-performance des 2GB de RAM DDR3 est un avantage complémentaire permettant à la plupart des programmes d'être compilés directement sur le XU4.

Performance SD/eMMC

Vous pouvez booter depuis une carte microSD ou un module mémoire eMMC. L'interface MicroSD supporte les performances supérieures du mode UHS-1. Vous trouverez ci-dessous les performances d'accès pour un fichier de 512MB en lecture/écriture pour les 3 supports de stockage.

Le stockage sur eMMC 5.0 est environ 7x plus performant qu'une carte Class-10 durant le test de lecture.

La carte MicroSD UHS-1 est environ 2x plus rapide qu'une MicroSD Class-10 (en test de lecture).

Le champion toute catégorie reste le stockage eMMC 5.0. Cependant, la carte MicroSD UHS-1 peut offrir une solution "low cost" attrayante pour de nombreuses applications!

Performance USB 3.0

Le XU4 est équipé de 2 port USB 3.0 SuperSpeed (ports Hôte).

Pour mesurer les performances USB , HardKernel à connecté un SSD via une interface USB-SATA. Le disque utilisé est un Toshiba SSD HDT312 128GB.

La vitesse de lecture USB 3.0 est environ 5 fois supérieure à celle d'un port USB 2.0 du XU4!

Performances Ethernet

The XU4 has an on-board Gigabit Ethernet controller. Our bi-directional streaming speed was measured at ~880Mbps.

Grâce à la technologie du contrôleur RTL8153, le contrôleur Ethernet du XU4 offre des solutions de connectivité ultra-performantes par rapport aux précédentes générations.

Performance du stockage réseau

De nos jour, les services de stockage NAS et Cloud sont devenu très populaires. HardKernel à testé le fameux OS OMV (Open Media Vault) sur le XU4 afin de pouvoir mesurer les performances du stockage réseau.

Un disque SSD a été connecté sur le XU4 via le convertisseur USB 3.0 vers SATA. Le port Gigabit Ethernet était connecté sur un PC en Windows 8 par l'intermédiaire d'un Switch.

Le test consiste à envoyer un gros fichier de 1.6 GB depuis le XU4 vers le PC par l'intermédiaire d'une connexion Samba. Le résultat est une vitesse de téléchargement de 75 à 85MB/sec.

La vitesse d'upload (téléversement) est mesurée à ~70MB/sec. Et même si ces performances sont vraiment impressionnantes, HardKernel continue à travailler sur des optimisations encore plus avancées.

Le XU4 est une option de choix pour réaliser son propre serveur de stockage Cloud!

La solution Heterogeneous Multi-Processing (HMP)

ODROID-XU4 est équipé de 4 gros coeurs (ARM® Cortex® -A15™ jusqu'à 2.0GHz) et 4 plus petits coeurs (ARM® Cortex® -A7™ jusqu'à 1.4 GHz) offrant un des possibilités de traitement avancés et performant tout en maintenant une consommation d'énergie la plus efficace possible.

La solution HMP de big.LITTLE™, Exynos-5422 peut utiliser le maximum de ses 8 coeurs pour pour gérer de façon optimal les traitements intensifs.

OpenGL ES 3.0 et OpenCL 1.1

Ce point concerne OpenGL ES 3.0 et OpenCL 1.1 pour les plateformes Linux et Android.

Le GPU (processeur graphique) ARM® Mali™-T628 MP6 offre les interfaces de programmation (API) clés pour le support de OpenGL ES 1.1, OpenGL ES 2.0 et OpenGL ES 3.0, OpenCL 1.1 (Full Profile) et Google RenderScript.

Mali-T628 est un GPU de choix pour les périphériques destinés à dominer la prochaine génération des périphériques embarqués (mobile). Il offre des optimisations permettant de réaliser des interfaces graphiques/utilisateur à couper le souffle. Ses domaines d'applications couvre le gaphique 3D, application graphique, réalité augmentée, génération de texture et reconnaissance vocale.

Vous pouvez télécharger le SDK complet pour OpenGL ES et OpenCL depuis le site développeur de MALI. C'est du libre!

La capture d'écran ci-dessous présente des applications OpenGL-ES et le media player de Kodi sous Ubuntu 15.04 Mate (avec HMP activé dans le noyau 3.10 LTS).
