Benchmarks & Specs

Last updated:
The Intel Atom Z2420 is a processor specifically designed for mobile devices. It was developed with efficiency in mind for compact form factors. It's based on the Penwell architecture and manufactured using the 32-nanometer process. A prominent feature of this Atom processor is its remarkable energy efficiency.

This allowed devices that used it to have very good battery life. For its time, this was an important aspect. We found the integration of the PowerVR SGX540 graphics unit particularly useful. This provided a solid foundation for everyday multimedia tasks and basic displays. With a Level 2 Cache of 1 MB, the Z2420 was well equipped for its typical applications.

The maximum memory bandwidth of 6 GB/s was sufficient for the intended tasks. This processor fit excellently into the then emerging, very compact devices. Its design often allowed for fanless designs and contributed to compactness. It reliably supported simple applications and provided basic connectivity.

The Intel Atom Z2420 proved to be an economical and practical solution for mobile devices. It met the requirements for mobility and low power consumption very well.
