Intel Atom N455 vs Intel Atom N435 vs Intel Atom D525
Intel Atom N455
► remove from comparison
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.

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 of the CPU is on a level with the slow Atom Z520.
An advantage of the interation, is the small overall power consumption of the CPU, GPU and memory controller (only 5 Watt TDP). Therefore, the chip is ideally used in small Netbooks and thin laptops.
Intel Atom D525
► remove from comparisonThe Intel Atom D525 is a dual core processor that is intended for nettops, but also used in netbooks (like the Asus Eee PC 1215N). It consists out of two Atom cores clocked at 1.8 GHz and due to HyperThreading, the D525 is able to process four threads at a time. The D525 misses Speedstep and is therefore running at 1.8 GHz all the time (and using a lot more power than other Atoms without load).
In the processor package, the Atom D525 has an integrated DDR2/DDR3 memory controller and the GMA 3150 called graphics card.
The performance of the D525 can be on a level of slow clocked single core CPUs like the Intel SU2700 or AMD K125 if both cores are used. In single threaded applications, the performance is clearly worse and only on the level of a 1.8 GHz Atom CPU.
