Qualcomm, the semiconductor giant unveiled its newest flagship processing chip, the Snapdragon 845. Here is everything you need to know.
The Snapdragon 845 is the next-generation mobile processor, that’ll most likely be found in many of next year’s major flagships. Just like its predecessor, the chipset retains the same 10nm footprint, but its revamped architecture brings new features like 4K HDR video capture on smartphones and improved AI processing.
At the reveal, Qualcomm said it’s focusing on Artificial Intelligence, security, immersion and connectivity with the new chip.
Immersion is basically the ability to capture and render at higher resolutions and quality for more realistic results. The Snapdragon 845 will feature an Adreno 630 graphics processor and Qualcomm’s Spectra 280 image signal processor. The ISP will allow for “Ultra HD premium” video capture at 60 frames per second.
Image and video processing improvements
Tim Leland, Qualcomm’s graphics lead, says the chipset’s Spectra ISP collects more color data with a combination of three methods – moving from 8-bit to 10-bit color, expanding its color gamut from Rec 709 to Rec 2020, and increasing luminance.
Spectra ISP further brings improvements to low light footage, while the Snapdragon 845 will also provide motion compensated temporal filtering as an image stabilization method. This stabilization method compares a frame in a video to the frames before and after it to figure out where an object’s outline should be.
Artificial intelligence improvements
AI is soon going to be running our lives in the future, Qualcomm wants improve the experience. The new Snapdragon 845 chipset does just that.
According to the company, the 845 is actually its third-generation mobile AI platform and its focus is on core optimizations, means the processor will assign tasks to different cores to execute based on the type of power needed.
The new chipset will also allow developers to choose which cores to use, and with all these improvements in the architecture, Qualcomm says the Snapdragon 845 can executes AI tasks three times faster than its predecessor.
Among the several other improvements, the Qualcomm has also added a “Secure Processing Unit” to the Snapdragon 845, to stop the hackers from exploiting security architecture. Chipset’s SPU has its own processor, random number generator, memory and power island to defend against attacks.
“It is its own secure island,” Qualcomm’s security lead Sy Choudhury said.
Company’s previous processor, Snapdragon 835 enabled gigabit LTE, but the Snapdragon 845 comes with the Qualcomm’s second-generation gigabit LTE modem, called the X20. The new modem will improve speeds over the Snapdragon 835’s X16 by 20 percent. It’ll now support five-carrier aggregation, an increase from four-carrier before.
You can expect to get your hands on a device with the latest processing chip real soon as the first devices to come with the Snapdragon 845 will arrive in early 2018.
