What are the differences between the Snapdragon 855 and the Snapdragon 845?

Each time there are more mobile devices that are popping up with the new processor Qualcomm, the Snapdragon 855. Mobile phones like the Xiaomi Mi 9 and the OnePlus 7 have opted for the last brain of Qualcomm, but what is the difference between the Snapdragon 855 and its predecessor, the Snapdragon 845? Continue reading here will tell you.

Design more efficient

One of the differences most notable is the manufacturing process. While the Snapdragon 845 is 10nm, the Snapdragon 855 is the first processor to the 7nm of Qualcomm. This results in higher energy efficiency, for superior performance.

The Snapdragon 855 also has the first design of CPU “tri-cluster” Qualcomm, in place of a traditional layout of 4 big cores and 4 smaller ones. The core is a design of CPU, based on Arm Cortex A76 highly synchronized. This core offers a clock speed higher maximum and more cache memory than the CPU based on Cortex-A75 of Snapdragon 845.

Ability of recording video of 8K

The GPU passes an Adreno 630 to a Adreno 640. Qualcomm estimates a performance increase of 20% between both generations, but does not reveal more details about it.

Higher download and upload speed, networks 5G

The 855 has the modem X24 LTE you would get 2 Gbps downstream and 316 Mbps upload. That is a bit faster than the download speeds of 1.2 Gbps, which is available from the modem X23 LTE the Snapdragon 845. Although the speeds of the real world are something far from these figures. Also feature the new Snapdragon X50 allows compatibility with networks 5G.

In general, the Snapdragon 855 is approximately a 29% faster the Snapdragon 845. Which allows a better processing of images, enhanced capabilities of machine learning(Artificial Intelligence), a Bluetooth audio superior through aptX Adaptive, support for video recording 8K, and a better experience for the gamers.

Although we must say that most of these improvements depend in great measure of the manufacturers of mobile and what they can do with this.
