Snapdragon 821 Specifications and Overview


This chipset has 1x 2GHz Dual Core Kyro+1x 2.4 GHz Dual Core Kyro CPU(s) with 3072 KB L2 cache. It belongs to the flagship category of chipsets that can 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 4 cores clocked at 2.4 GHz. It can provide exemplary levels of performance with maximum efficiency 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 Kyro architecture which was released in 2016.


This SoC was built on 14nm lithography which results in extremely efficient performance.

Maximum Camera Support

This SoC can effectively support a 51 MP camera at max indicating that it is mostly used on flagship level mobile devices

64 Bit

This processor has 64 bit support.
64 bit support allows an 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 Adreno 530. It has DirectX 12+OpenCL API(s) running on it resulting in reduced overheads and extremely smooth graphical performance within games and movies. Graphically demanding apps will run properly on this SoC
