The Intel Atom N450 is a small and cheap entry level CPU for Netbooks and small laptops. In the package is an integrated memory controller for DDR2 main memory and the GMA 3150 graphics card.
The performance of the whole system (Atom N450 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. To decode HD videos in 1080p the N450 / GMA3150 needs the help from a additional chip like the the ION2 or Broadcom video decoder.
An advantage of the interation, is the small overall power consumption of the CPU, GPU and memory controller (only 5.5 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.
