ARM Cortex A9 is the architecture behind the next-generation mobile processors, and as we previously disclosed, we will see dual-core models up to full 2GHz with power consumption around 0.25W for each core. This may be Intel's low-power Atom processor to look like a power-hungry monster and now want the ARM show that despite significantly lower power consumption does not skimp on performance of the Cortex A9.

In a video comparison published on You tube has ARM compared two systems where one uses a 1.66 GHz Atom CPU, while the second uses a dual Cortex A9 at only 500MHz.

The test drive is a bit simple web browsing, which is one of the most common uses for the devices with these CPUs. Although the test platform with the Cortex A9 may not be using a GPU in this case can handle it remarkably well despite its low clock speed.

When and how we may see Cortex A9 architecture market is unclear. Cortex-A8 architecture is currently used by, among other things, Apple iPhone, but also newer Snapdragon processors based on this architecture.
