Intel Atom N475 vs Intel Atom N550

Intel Atom N475

► remove Intel N475

The Intel Atom N475 is a small and cheap entry level CPU for Netbooks and small laptops. In the package is an integrated memory controller for DDR2 and DDR3 main memory (max 2 GB, single channel) and the GMA 3150 graphics card. Compared to the N455, the N475 is higher clocked and is specified for 6.5 Watt TDP instead of 5.5 Watt of the N455. The N470 offers only DDR2 support.

The performance of the whole system (Atom N475 and integrated GMA 3150) is only sufficient for basic tasks like surfing the web, or office working. HD video, video cutting, advanced photo editing and of course gaming may overstrain the GPU and CPU. Compared to the previous Atom generation, the performance gain is said to be only marginally above a similar clocked Atom Z / GMA 950.

An advantage of the interation, is the small overall power consumption of the CPU, GPU and memory controller (only 6.5 Watt TDP). Therefore, the chip is ideally used in small Netbooks, MIDs, and thin laptops.

Intel Atom N550

► remove

The Intel Atom N550 is a dual core Atom CPU for small netbooks and offers relative slow performance but also features a low power consumption. Because of the "in order" execution, the Atom series CPUs are slower than Core / Celeron CPUs at the same clock rate. The N550 is produced in 45nm and supports DDR3 main memory. It contains the GMA3150 graphics card on the same chip.
