Atom Z2420 Specifications and Overview

Released in 2013


This chipset has 1x Atom CPU(s) with 512 KB L2 cache. It belongs to the lower level category of chipsets that cannot easily run most apps out there. The lower clocked CPU is used under battery saving conditions while both of them may be activated under extreme workloads such as gaming, benchmarking or multitasking but it depends on whether App will effectively use all the CPUs or not.

Number of Cores

This System on Chip has 1 core clocked at 1.2 GHz. It can provide extremely low levels of performance for today's apps and multitasking. Cores of a SoC have a great impact on the performance as they determine the how the workload is distributed across the chipset as well as the maximum number of apps that can run without stuttering on the smartphone/tab etc.


This SoC was built on Lexington architecture which was released in 2013.


This SoC was built on 32nm lithography which results in average efficient performance.

Maximum Camera Support

This SoC can effectively support a 16 MP camera at max indicating that it is mostly used on lower-mid level mobile devices


This processor doesn't have 64-bit support. 64-bit support allows a SoC to manage more data along its bus width and allow more quantity of RAM to be paired with the chipset. Apps also run more easily and efficiently on 64-bit processors.


This chipset has PowerVR SGX540. It has DirectX 9.2/9.3 API(s) running on it resulting in lesser reduced overheads and average/low graphical performance within games and movies. Graphically demanding apps may not run properly on this SoC.
