Qualcomm Snapdragon 821 Review, Phones, Specs, Benchmarks

Qualcomm Snapdragon 821 was introduced in mid 2016 as a high end ARM-based single chip system found on Android and tablets. It was built to complement the outdated 820, building on the technology leadership introduced with the Snapdragon 820 platform. The 821 is improved to deliver faster speed, more power savings and greater application performance.

Process Technology (nm)

With a clear cut decrease from 20nanometre to 14nanometre, power consumption is less and there’s increased efficiency compared to its predecessors. The greater the performance the more power being used, the Snapdragon 821 uses Samsung’s 14nm fabrication process when compared with the A10 of 16nm overall performance will show up in things like memory speed, L1 and L2 cache sizes and number of instructions per clock the CPU can execute.

It is built to deliver a 10% increase in performance over the 820 with the Qualcomm Kryo quad-core CPU reaching up to 2.4GHz speed. The 821 can use all its cores simultaneously when compared to A10 that can only swap between using high performance core cluster and energy efficient cluster. It also has performance core and two efficiency cores compared to that of the Snapdragon 810 modem, while the CPU is based on a 64-bit architectural design.

Qualcomm Snapdragon 821 graphics

When it comes to API support the Adreno 530 GPU from Qualcomm supports OpenGL ES3.2 and Vulkan 1.0 whereas Apple supports OpenGL ES 3.0 and its own Metal API. The Snapdragon 821 is engineered on Adreno 530 and it offers a 40% improvement in graphics performance when compared to the Adreno 430 which makes snapdragon 821 processor 5% performance increase over the 820 processor. The Adreno 530 in the Snapdragon 821 also performs better than the GPU in the A10 fusion.


On a 14-bit Qualcomm Spectra, the image signal processor supports a capture of about 28 megapixels with zero shutter lag. Its sure to deliver high resolution DSLR-quality images using a heterogeneous computation for advanced processing and in addition saves power.

Also to note is the Qualcomm 3.0 quick charge technology supported on the 821 which offers up to 18W charging boost for all handsets. It comes packed with the X12 LTE modem, which is 3 times faster with upload speed of about 33% faster download speed compared to the X10 LTE.

The X12 LTE has a download speed of about 600Mbps and 150Mbps, multi-gigabit 802.11ad and 802.11ac Wi-Fi process. Three out of four iPhone 7 models use modems from Qualcomm.

Benchmarks (AnTuTu)

Over at AnTuTu, specifically on the version 6, the chip reaches a low of 138072, avg of 147292, median of 149386 and max points of 159866.
