Hello Mi Fans,
Qualcomm launched its new flagship mobile platform, Snapdragon 845. The chipset comes with a slew of new features that promise to enhance security, battery life and the overall performance of smartphones. It has been confirmed that Snapdragon 845 will be used in Xiaomis next flagship device and it is likely that it will power a number of other flagship smartphones of 2018.

According to Qualcomm, there will be at least 25% increase in the performance of Snapdragon 845 as compared to its predecessor Snapdragon 835. It is also being claimed that the new chipset will result in 30% more battery life than Snapdragon 835. Also, Snapdragon 845 is the first mobile platform on which Qualcomm has added a physically separate processor called 'Secure Processing Unit' to store biometrics scans in order to make devices more secure. So, there are a number of differences between the two processors. Here, we compare aspects of the CPU, memory, image signal processing, and more.

Snapdragon 845 Mobile Platform
They say the best is yet to come. We say, with the Qualcomm® Snapdragon™ 845 Mobile Platform, it’s here. Every forward-looking feature—including immersive XR experiences, an intelligent personal assistant, and advanced vault-like security—is enabled by the Snapdragon 845 Mobile Platform. It also delivers up to 1.2 Gbps peak download speeds across a broader spectrum—our platform is smarter and faster than ever before.
The Snapdragon 845 Mobile Platform is engineered with the functionality and features that will allow users to do even more with their mobile devices.

Qualcomm Spectra 280 ISP
The Qualcomm Spectra™ 280 ISP is designed to deliver a premium camera and XR experience, with the high-performance capture of up to 16 MP at 60 images per second. Video enthusiasts will appreciate cinema-like quality video thanks to ultra HD premium capture with richer color.

Adreno 630 Visual Processing Subsystem
Deliver larger-than-life immersive experiences with the Qualcomm® Adreno™ 630 Visual Processing Subsystem (including GPU, VPU, and DPU), featuring room-scale 6DoF with SLAM, Adreno Foveation, and a 30% improvement in graphics/video rendering compared to the previous generation.

AI Platform
The 3rd Generation Qualcomm® Hexagon™ 685 DSP supports sophisticated, on-device AI processing, delivering richer camera, voice, XR and gaming experiences.

Qualcomm Secure Processing Unit (SPU)
We designed the Snapdragon 845 with an entirely new Qualcomm® Secure Processing Unit (SPU) that is engineered to help protect personal data with vault-like security. Biometrics used for authentication can be stored in isolation, helping to keep precious data out of prying eyes.

X20 Modem & Wi-Fi
Experience fiber-optic speeds with the Snapdragon X20 LTE Modem. New flexibility means that more operators around the world can offer lightning-fast Gigabit LTE service, now with up to 20% faster peak and real-world speeds compared to our last generation X16 LTE modem. Users can also experience similar lightning-fast speeds with 802.11ad multi-gigabit Wi-Fi and integrated 2x2 802.11ac.

Virtually All-Day Battery Life and Quick Charging
Our energy-efficient Snapdragon 845 Mobile Platform is engineered for all-day battery life and includes our Qualcomm Quick Charge™ 4+ technology—capable of up to a 50% charge in only 15 minutes* so even the most demanding applications can run all day.
