The Chromebook C910 is the first Chromebook to have a 15.6-inch display. This large display is the biggest differentiating feature from other Acer Chrombeooks. The laptop runs ChromeOS and has a maximum RAM capacity of 4GB. Another identifying feature of Acer Chromebooks is the use of Intel processors and memory. The C910-C453 uses the Intel® Celeron® 3205U processor Dual-core 1.50 GHz. The C453 version also is limited to a screen resolution of (1366 x 768), smaller than the more expensive C910 models which have a resolution of (1920 x 1080). The processor, screen resolution and the 16GB solid state drive are the three features of the C910-C453 that discern it from the rest of the laptops in Acer's C910 Chromebook series.
The laptop can be identified by the part number: NX.EF3AA.003, with the last two digits making it different from the other C910 laptops.
