CES 2022: Qualcomm Gives Full Snapdragon 835 Processor Details

Qualcomm wants to immerse the globe in its Qualcomm Snapdragon 835 processor. The chip that'south going to power nearly of the leading Android smartphones this yr is designed to grab information from the air at Gigabit speeds.

Information technology will also turn all that data into rich virtual and augmented reality (VR and AR) experiences, according to several executives at a pre-CES conference.

"The Qualcomm Snapdragon 835 is going to be i of the key devices that propels the VR use example," said Qualcomm Senior Vice President, Keith Kressin.

During the 24-hour interval-long briefing, information technology is made clear where Qualcomm thinks mobile technology is going: non into traditional desktop uses but more to do with VR and AR. All of the components in the Qualcomm Snapdragon 835 seem to be designed for that chore such as environment sound, eye tracking, a meliorate GPU, depth-perceiving cameras, and very high-speed LTE streaming.

"AR is in abiding use. The vision is that [AR devices] would exist on literally all day," Kressin said. "I need improve bombardment life, I need a superb brandish, I need higher frame-rates, and I need ameliorate audio. All of these requirements are what'south driving the side by side generation of mobile devices."

Commercial devices with the Qualcomm Snapdragon 835 will start to announced in the start one-half of 2022, Qualcomm revealed. As for who volition make them, "Expect at the OEM partners we had the Qualcomm Snapdragon 820 and 821," Kressin shared. That includes pretty much every smartphone visitor yous can think of other than Apple and Huawei.

Backing Away From the CPU?

The hardest matter to sympathize about the Qualcomm Snapdragon 835, especially if y'all're thinking from the desktop CPU prespective, is how much Qualcomm has been prioritising elements of the Arrangement-on-Bit (SoC) other than the CPU.

This has been coming for years and it can exist tricky considering the idea relies on firmware and the Android operating organization to properly distribute work to not-CPU components of the chip. During the conference, it is striking how lilliputian Qualcomm talked near its Kryo 280 CPU as compared to other components.

Is that considering it isn't truly a custom cadre?

Qualcomm had a weak twelvemonth in 2022 with the Qualcomm Snapdragon 810 line-up that seemed rushed to market, losing the Samsung Galaxy S6 equally a client simply to regain the business concern with the Snapdragon 820 and via the Samsung Galaxy S7.

The Qualcomm Snapdragon 835 is "built on ARM Cortex engineering" with four two.45GHz Cortex-A57 cores and four one.9GHz Cortex-A53 cores. The danger is that by using ARM'due south designs rather than the Qualcomm Snapdragon 820s custom cores, Qualcomm'southward customers volition expect more than closely at other manufacturers using ARM cores, such as MediaTek and the in-house fleck divisions of Samsung and Huawei.

Qualcomm tries to counter that past pointing out that this is the showtime 10nm mobile processor, offering improved efficiency and also saying the CPU is 'tightly integrated' with other components using the new Symphony system manager. The latter can be operated automatically yet has customisable aspects that app developers could tap onto. This distributes work across the CPU, GPU, DSP, and more exotic components, letting the adjacent-gen Qualcomm SoC to work better than it would with CPU alone.

"There'south some stuff we're working on with Google that we tin can't talk about, but we have some ways of making this stuff happen under the hood," Kressin added. "We take to make certain that heterogenous scheduling happens automatically, but we likewise have to support the super-developers" who want more control, he noted.

How that will combine with Qualcomm's recent proclamation that it volition back up Windows 10 on mobile PCs, including legacy Win32 apps, is yet to exist seen.

Better Battery Life, Quicker Charging

The Samsung Galaxy Note7 disaster, which came virtually by cramming in besides much battery in too little space, shows that there is still need for chipmakers to exercise their part on battery life.

Every bit is, the Qualcomm Snapdragon 835 consumes 25% less ability than its predecessor, according to Qualcomm. That means seven hours of 4K streaming video and 2 hours of VR gaming on a typical device, the company revealed. Clearly, these new uses are really ability hungry.

Since Qualcomm can only practice so much on power efficiency, it as well introduced Quick Charge 4, a concept that supposedly charges a smartphone to five hours of use in five minutes. To futurity-proof itself, it has a USB Type-C port that is power delivery compliant.

Keeping things running also means shifting a lot of work to the Hexagon DSP, probably the least understood part of Qualcomm's chips. Hexagon is basically a low-power CPU that handles a bunch of specialised tasks. Image processing? Some of that's on Hexagon. Move tracking during VR? Hexagon. Sound? Yep, Hexagon.

"While the GPU is more efficient than the CPU, the DSP is more efficient than the GPU," Kressin said.

Snapdragon 835 Camera Capture

Dual Cameras for Photos and VR

The new Adreno 540 graphics chip improves 3D performance by 25% over the previous generation, Qualcomm confirmed. Information technology also enables features like HDR10, which improves colours; foveated rendering, which most clearly renders what you're looking at rather than elements in the periphery of a scene; and low latency, which allows you to move your caput to smoothly motion effectually in VR scenes.

With one 32MP or two 16MP cameras running at the same time, the Qualcomm Snapdragon 835 supports various dual-camera functions. One option looks simply like the Apple iPhone 7 Plus's cameras, with a regular lens and a zoom lens. Another looks more like the Huawei P9, with a colour module and a blackness-and-white equivalent to amend depression-calorie-free operation and saturation quality. Smartphones based on this chip will also record 4K HDR video with electronic prototype stabilisation, Qualcomm added.

Having multiple epitome sensors on the aforementioned surface also gives a device depth perception, Tim Leland, Qualcomm Vice President of Product Management pointed out. "If you want to be able to collaborate with a VR earth, it needs to be able to capture your easily in the VR brandish," he shared.

Qualcomm Snapdragon 835 Modem VR

Jumping to Gigabit LTE

Qualcomm typically has the most advanced 4G modem technologies in the business. The Qualcomm Snapdragon 835 will feature an X16 modem, a characteristic that Qualcomm announced earlier this year that will be able to boost LTE to Gigabit speeds.

The keys to gigabit LTE are triple 20MHz carrier aggregation with 256-QAM encoding and 4x4 MIMO antennas, said Qualcomm Senior Director of Marketing, Peter Carson. That's going to be starting time introduced with a Netgear hotspot in Commonwealth of australia this January.

Other components in the Qualcomm Snapdragon 835 include 802.11ac Wi-Fi, Bluetooth v, and optional 802.11ad, a curt-altitude loftier-speed transfer system that Qualcomm had been promoting for some time though information technology hasn't gotten much uptake nevertheless.

Nosotros'll attempt to get some WUalcomm Snapdragon 835 demos, if they're on offer, hither at CES.
