== CPU/RAM PERFORMANCE ==
We ran several benchmarks to measure the computing power on the XU4. The same tests were performed on the Raspberry Pi 2 Model B, ODROID-C1, ODROID-U3 and ODROID-XU4.
The values of the test results were scaled uniformly for comparison purposes. The computing power of the XU4 was measured to be ~3-4 times faster than the latest Raspberry Pi 2 thanks to the 2Ghz Cortex-A15 cores and much higher memory bandwidth. Using the XU4 as a computer provides a "desktop like" experience, unlike the sluggish performance of most single-board computers!
Particularly for developers, compiling code on the XU4 is about 3 to 4 times faster. The high-performance 2GB DDR3 RAM is an additional advantage allowing most programs to be compiled directly on the XU4.

== CPU/RAM PERFORMANCE ==
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!

Following eMMC 5.0 test was done with 16GB model (8GB model is slower than 16GB).
