Intel Atom N435 vs Marvell Armada PXA1908 vs Intel Atom D525

Intel Atom N435

Marvell Armada PXA1908

The Marvell Armada PXA1908 is an ARM based low end SoC for smartphones and tablets. The chip was announced in late 2014 and integrates four 64-Bit Cortex-A53 processor cores with up to 1.2 GHz. As a graphics card, the SoC integrates a Vivante GC7000UL. Furthermore, a LPDDR2/3 memory controller and a HSPA+/WCDMA/LTE Cat. 4 (max. 150 Mbit/s) radio is integrated. The SoC is manufactured in 28nm and also suited for small smartphones. 

Intel Atom D525

The 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.
