premier vrai test du Snapdragon (ARM) dans les pc portables
c'est plutôt performant en terme CPU
+Positif
*stable and high quality metal housing
*good system performance
*very good and accurate OLED panel with 120 Hz
*sufficient connections including USB 4
*good input devices
*long battery life
*good speakers
- Négatif :
*RAM not upgradeable
*constant PWM flickering
*limited compatibility with games and programs
*slow microSD reader

Un premier test
C'est pas si mal
C'est pas si mal
Sur le plan technique, on note des fréquences en hausse pour les parties CPU et GPU (+15 % et +20 %) ainsi qu’un nouveau processeur d’images (ISP).
(...)
la prise en charge de deux dalles 4,3K (contre deux dalles 3K pour le XR2 Gen 2),
une vitesse d’affichage allant jusqu’à 90 images par seconde
et l’ajout de deux caméras supplémentaires pour monter jusqu’à 12 modules caméras pilotés de manière concomitante.

Il y a quand même un écart relativement important en faveur du snapdragon en terme d'autonomie

According to Qualcomm, the chip, which is manufactured using TSMC's N4P process, can be operated with a TDP of 25 to 80 watts,
but most notebooks should be satisfied with a maximum of 45 watts.
A power loss of 12 watts is targeted in devices without fans.

The CPU has the same core setup as the 778G+ - 1 Kryo 670 Prime core (Cortex-A78) but runs up to 200MHz faster at 2.7GHz, 3 Kryo 670 Gold (also Cortex-A78) at up to 2.2GHz, and 4 Kryo 670 Silver (Cortex-A55) at up to 1.9GHz.
Thanks to the slight bump in clock speed, the CPU is around 5% faster, while the GPU is quoted as 10% faster than the Snapdragon 778G+.
