What is Qualcomm Snapdragon 845 ?

The Snapdragon 845 processor is a direct successor to the popular Snapdragon 835 chip from last year and will likely bring improved performance, better energy efficiency and improved image processing.

New generation for Qualcomm’s high-end SoC. The Snapdragon 845 chip highlights new architectures for virtual reality and AI, as well as better connectivity with the X20 modem. We should find this SoC in high-end smartphones presented next year.

Qualcomm unveils its new high-end SoC. If those present at the Snapdragon Tech Summit were unsatisfied during the presentation, a statement from the manufacturer delivers the technical specifications of this Snapdragon 845.

The Snapdragon 845 embeds eight Kryo 385 cores etched in 10 nm clocked up to 2.8 GHz. Qualcomm promises increased performance by 25% compared to the previous generation. An Adreno 630 provides the GPU part, the Spectra 280 Image Signal Processor (ISP) completes the graphic part of the SoC.

Thus, it will support a camera equipped with a double sensor of 16 megapixels or a single sensor of 32, the 4K up to 60 fps and two 2400 x 2400 pixels with 120 fps in the case for example of an integration with a helmet of reality Virtual.

In the field of AI, the group announces support through its Tensorflow Lite Snapdragon Neural Processing Engine SDK and Open Neural Network Exchange, in addition to the classic TensorFlow and Caffe frameworks.

As for security, the Snapdragon 845 introduces an isolated hardware subsystem called the Secure Processing Unit (SPU). It is designed to “add safe-box features to Qualcomm’s existing layers of mobile security solutions”.

To 5G
Side connectivity, WiFi 802.11ad and Bluetooth 5 are in the game. Above all, we go from the X16 modem to the X20. At a press briefing on 5G last week in Paris, Laurent Fournier, CEO of Qualcomm France, explained that this X20 modem must be embedded in the products announced in 2018, so we must expect that The first smartphones, even tablets or PCs, designed on the Snapdragon 845 are presented at the beginning of the year at the CES and the MWC.

For the record, the X20 will support up to 5 aggregated 20 MHz bands for 1.2 Gb / s peaks in downstream rate.

And we are still in the 4G. Its successor, the X50 modem will be 5G NR, based on the standard defined by the 3rd Generation Partnership Project (3GPP). It currently peaks at 1.2 Gb / s during PoC led by Qualcomm with ZTE and China Mobile. The X50 should be aligned with the premium smartphones introduced in 2019.
