Easily and Quickly Snapdragon 845 vs 835 in 5 Points. The Snapdragon 845 chipset (System-on-Chip) has become a standard for high-end smartphones as it boasts premium features for gaming, photography, among others. The SoC is built on the Samsung’s 10nm process node which also produced last year’s flagship processor – Snapdragon 835. In this post, we shall see the 5 aspects at which the Snapdragon 845 brought up-gradation.

Snapdragon 845 has a better overall design
Though, the two high-end mobile platforms are built on the 10nm process technology. The Snapdragon 845 houses more transistors (more than 3.5 billion) in a slightly bigger die size of 92 mm^2 to power the computing needs of the 2018’s premium smartphones.
Snapdragon 845 Has More Powerful CPU Clusters
The big.LITTLE architecture implement led in the Snapdragon 835 enabled a perfect balance of performance and energy efficiency. On the other hand, the Snapdragon 845 adopts the ARM DynamIQ architecture in which CPU cores are no longer confined to a dedicated cluster, but are now integrated into a single, larger cluster.
The DynamIQ enables a smooth instruction flow between the CPUs resulting in increased overall efficiency and performance.
In addition, the custom-designed Kryo 385 cores are derived from the ARM Cortex-A75 and Cortex-A55 which are the upgraded versions of the Cortex-A73 and Cortex-A53 IPs respectively.
Snapdragon 845 Is More Powerful For Gaming Needs
Compared to the Adreno 540 GPU sitting in the Snapdragon 835, the Adreno 630 GPU of the SD 845 brings architectural changes which boost the FP32 Performance. Further, the Adreno 630 implements the Bifrost architecture with a slightly higher GPU clock.
SD 845 Upgrades The Connectivity Features
The Snapdragon 845 chipset integrates the X20 LTE modem which enables downlinks up to 1.2 Gbps (Cat. 18). In addition, the SD 845 also upgrades the WiFi specifications.
Snapdragon 845 Has Upgraded Co-processors
In terms of photography, the SD 845 brings new hardware to enable computational photography and video capture. For instance, the Spectra 280 is an upgraded version of the 180 which sits in the Snapdragon 835.
Further, Qualcomm uses vector approach for enabling AI applications. For the uninformed, the Snapdragon 845 does not have a dedicated NPU to executive Neural Network Algorithms unlike the Kirin 970. The SD 845 uses the onboard GPU and CPU with the Hexagon 685 DSP to run neural network and other AI frameworks.
In addition to the above, the key difference between the Snapdragon 845 and the Snapdragon 835 is that it introduces a “safe handling unit.”
Qualcomm integrated a security engine into the processor (CPU), and opened a security layer for it. This security processing unit is mainly used to store private information such as fingerprints, irises, voices, and faces of users.

Of course, the Snapdragon 845 Is More Powerful Than the Snapdragon 835. But how performance or what’s the performance difference. As per the analysis, the Snapdragon 845 Is significantly faster than the Snapdragon 835.
From the above AnTuTu running points data, compared to the Snapdragon 835, Qualcomm Snapdragon 845’s comprehensive performance, CPU performance, UX performance, and 3D performance are dominant. Hence, the Snapdragon 845 is a true upgrade (significant) to the Snapdragon 835.
In a nutshell, Snapdragon 845’s new Kryo 385 CPUs boost the performance by 25%, the performance of the Adreno 630 GPU is increased by 30%, and the power consumption is reduced by 30%.
Snapdragon 845 Phones
From the performance points (benchmark) perspective, the Snapdragon 845 is slightly behind the Apple A11 Bionic. However, the Qualcomm’s flagship chipset has become a standard for flagship Android smartphone by powering more flagships that its predecessor (Snapdragon 835).
