Acer Aspire One D257 Specifications Notebook: Acer Aspire One D257 Processor: Intel Atom N455, 1.6 GHz (1 core, 2 threads, 64-bit) Graphics Adapter: Intel Graphics Media Accelerator (GMA) 3150 Memory: 1024 MB (upgraded to 2 MB) Display: 10.1 inch, 16:10, 1024 x 600 pixels Weight: 1.1kg (2.43 pounds) Intel Atom N455 The Intel Atom N455 is a small and cheap entry level CPU for Netbooks and small laptops. In the package is an integrated memory controller for DDR3 main memory (the difference to the Atom N450) and the GMA 3150 graphics card. The performance of the whole system (Atom N455 and integrated GMA 3150) is only sufficient for basic tasks like surfing the web, or office working. HD video, video cutting, advanced photo editing, multitasking and of course gaming may overstrain the GPU and CPU. Compared to the previous Atom generation, the performance gain is only marginally above a similar clocked Atom N280 / GMA 950. An advantage of the combination, is the small overall power consumption of the CPU, GPU and memory controller (only 6.5 Watt TDP). Intel states 20% power reduction and 60% package reduction. Therefore, the chip is ideally used in small Netbooks, MIDs, and thin laptops. Compared to the Z500 series combined with the US15W chipset (2.4+2.3 W), the power consumption is similar.
