Qualcomm launched the Snapdragon 8 Gen 1 mobile processor for smartphones at the Snapdragon Tech Summit in Hawaii late on Tuesday, adding substantially more performance and AI-powered features to 2022 smartphones. However, one of those may be controversial. While you may be used to your phone always listening for commands, are you ready for its camera to be always on, too?
In an interesting twist, Snapdragon 8 phones will even be able to mint NFTs.
Qualcomm already powers a substantial chunk of the world’s smartphones, from the Asus ROG Phone 5s to the Google Pixel 4a and 5, the OnePlus 9, and the American version of the Samsung Galaxy S21+. Now the new Snapdragon 8 Gen 1 is poised to help launch even more, beginning in the fourth quarter of this year.
With the launch, Qualcomm also rolled out a new branding structure. Snapdragon 8 Gen 1 represents a simplification of the company’s branding, versus the triple-digit Qualcomm Snapdragon 888 5G brand used last year. The executives said that consumers preferred the simplified, single-numeral nomenclature, which also now assumes “5G” without explicitly stating it. In an interesting twist, they’ve even dropped the company name from the Snapdragon logos, as they believe that “Snapdragon” is now a standalone consumer brand.

Like most mobile SOCs, the new Snapdragon 8 Gen 1 represents a fusion of several different logic blocks, each with their own specific functions: the Kryo CPU, the Adreno GPU, the Spectra Image Signal Processor (ISP) for camera imaging, a Sensing Hub, and the integrated modem. In the latter case, the processor has moved wholesale to 5G, with support for 5G multi-SIM and both 5G mmWave and sub-6 GHz frequencies.
What’s inside the Snapdragon 8 Gen 1
Interestingly, Qualcomm’s playing the details of the Snapdragon 8 Gen 1 a little close to the vest, compared to what accompanied the rollout of last year’s Snapdragon 888. In fact, the company has officially stopped providing specific model numbers for the new cores — so last year’s Kryo 680 CPU is now just the Kryo (Snapdragon 8). “When we moved to our new visual identity, the Snapdragon 8, part of the goal is to simplify our branding across the board, including the 3-digit number schemes across our IP cores,” a representative said in an email. “We wanted to have the premium-ness of the 8 carry our technology cores (Kryo, Adreno, and Hexagon).”
The Snapdragon 8 Gen 1 is noteworthy for its use of the Cortex-X2, the next-gen “prime core” technology Arm revealed in May alongside the A710 performance core and the A510 efficiency core, which also appear in this Snapdragon chip. All three are members of the Arm v9 family, the next-gen architecture that Arm launched in March, promising a 30 percent performance improvement. Qualcomm itself is promising a 20 percent performance improvement over the 888 with a 30 percent power savings.
As Qualcomm recently said, these chips don’t include the Nuvia Arm core technology that the company bought in January. That will come in 2023.

Here’s a quick summary of what we know about the new Snapdragon 8 Gen 1 chip. Qualcomm says that it’s fabricated on a 4nm process versus the 5nm technology used by the prior-gen Snapdragon 888.

AI
Artificial intelligence is sometimes difficult to define on the PC, but on the smartphone it’s quickly become synonymous with two things, computational photography and how your phone processes voice commands. With the Snapdragon 8 Gen 1, Qualcomm has improved across both vectors, according to Ziad Asghar, Qualcomm’s vice president of product management of its Snapdragon technology roadmap. The Hexagon’s performance has roughly doubled, Asghar said, and the available memory to the Hexagon has doubled too.
From a performance perspective, Qualcomm’s numbers have improved quadruple the AI performance, with twice the tensor accelerator performance and 1.7X more power efficiency, Asghar said. There will be 8-bit plus 16-bit mixed integer support. What will be more interesting is what the AI engine can do such as video bokeh effects from ArcSoft, improved natural language processing, and a new “Leitz Looks” filter from Ernst Leitz Labs that you’ll be able to apply to photos to give them the look of Leica cameras.
Qualcomm
The Snapdragon 8’s Hexagon AI engine can also interact with the integrated 3rd-gen sensing hub, with a couple improvements that could seem cool or otherwise very creepy. Asghar said that Qualcomm is working with Sonde to develop technologies to listen to your voice as you speak to determine if you’re suffering from a health issue such as asthma or the coronavirus. Hugging Face natural language processing will scan your voicemail messages and apply sentiment analysis. Is it really important that your brother speak with you?
AI is also being used with antenna tuning, helping to re-route the antenna signal path depending on how the phone detects you’re holding the phone. (This certainly sounds like a possible solution to the iPhone “antennagate” scandal, and Steve Jobs’ famous response: “You’re holding it wrong.”)
Finally, Asghar said, Qualcomm is adding a “completely new experience,” the always-on camera system which represents a fourth ISP. What that allows you to do is bring in completely new use cases where your phone can unlock just by looking at it and “also prevent unnecessary looks at your display,” Asghar said. Essentially, your phone will be always looking for your face, eliminating the need to “unlock” it.
Qualcomm may be walking a fine line here. Google Glass failed, in part, because users were never sure if they were being recorded or if their behavior was being tracked and there were similar questions asked of Facebook regarding the recent introduction of its own smartglasses. Some laptops have included privacy shutters over their webcams because of concerns, justified or not, that users could be illicitly recorded.
In response to a question about the ethics of an always-on camera, Asghar noted that Qualcomm attempts to “make sure that the data that is there stays on the device.” Any images captured by the camera will be kept on the device itself. “As you know, these are capabilities that add to experiences…and [we want] to make sure that we have solutions that are abiding by all the privacy parameters and everything,” Asghar added.
More importantly, Asghar said he believed that the always-on camera would be an OEM-enabled feature, meaning that it will be up to the smartphone OEM to actually enable it as well as provide user controls to manage its use.
Camera
Otherwise, the Snapdragon 8 Gen 1’s camera has added some interesting new features.
Qualcomm is calling its new camera ISP brand “Snapdragon Sight,” representing what the Snapdragon 8 Gen 1’s camera can do. It can take pictures, certainly, but also recognize what the camera is taking photos of. Last year’s Snapdragon 888 offered AI-based auto-exposure and auto-face detection, but the Snapdragon 8’s Spectra Image Signal Processor now performs intelligent face detection. That matters, according to Judd Heape, vice president of product management at Qualcomm, when the camera is asked to unlock the phone for a user whose face is partially obscured by a mask. The camera’s sensor can now map up to 300 “facial landmarks”, tracking your eyes, nose, mouth, cheeks, and so on for animojis and other applications where the camera has to map your facial expression.
Qualcomm
Smartphone cameras powered by Qualcomm Snapdragon 8 processors will also feature dynamic range that has increased by four stops, part of a move from a 14- to an 18-bit ISP that will see the ISP capturing over 4,000 times more data than before, or 3.2Mpixels per second.
While the 888’s camera ISP allowed users to shoot 8K video, the 8’s ISP will add HDR capabilities to that 8K video. There’s also a dedicated hardware engine that will apply bokeh in real time to 4K video, too. In addition to the various still-image capabilities talked about in the specifications, Qualcomm also developed “Panoramic View,” a 140-degree wide panoramic-like shot that can be captured in a single shot, without the need to stitch photos together.
The AI engine and camera engine will work together to perform extreme ultra zooming. Basically, it’s digital zoom with smart interpolation to eliminate graininess. Last year’s Snapdragon 888-powered “night mode” stitched together about six frames to form a composite image. The Snapdragon 8’s camera will combine about 30 frames, delivering “five times better night mode,” Heape said. That’s because each pixel in a night scene is tracked, so the camera can intelligently filter out the pixel “movement” caused by your hands shaking. The result will be a sharper, crisper image, he said. Finally, the company is using AI to eliminate chromatic aberration from wide-angle lenses.
Heape also provided a few more details about the always-on camera will work. Essentially, it will be able to automatically unlock your phone, but also notice when someone may be peering over your shoulder and alert you. We’ve seen this before in the PC space. The “Glance” utility Lenovo bundled with its ThinkPad X12 Detachable Gen 1 tablet, for example, blurs your screen if you’re not there. Dell’s laptops simply detect your presence, then turn on the Windows Hello-enabled webcam.
Qualcomm also showed off a video where a cook propped up his smartphone against a mixer, then periodically crouched down to unlock his phone and turn on the screen — and showed that the recipe that he was using. The phone can also hide sensitive notifications when someone else may be looking at it, too.

Gaming
Mobile gaming may not be something you think of when you think of mobile phones — well, nothing more than a casual round of Candy Crush. But mobile versions of Player Unknown: Battlegrounds and similar games can sell smartphones, too. Here, processing power and GPUs rule, just as they do with PCs. Essentially, GPU performance has gone up by 30 percent within the new Adreno, while power consumption has dropped by 25 percent.
Qualcomm is promising three improvements with the Snapdragon 8. First, a new Adreno GPU frame motion engine that will essentially double frames at the same power consumption, or reduce power up to 50 percent at the same frame rate. Second, the new chips will add “desktop-level volumetric rendering,” executives said. Finally, the company is promising a “pro” level version of variable rate shading, which will allow the GPU and display to sync up to provide “tear-free” gaming with fewer visual artifacts.
Modem, trust and security
On the modem side, Qualcomm is bringing together full mmWave and sub-6-GHz enablement, Asghar said. More importantly, Qualcomm is introducing 5G uplink carrier aggregation, where multiple uplink channels will be able to be used simultaneously to improve upload bandwidth. The X65 modem will support 10Gbit 5G, chief executive Cristiano Amon said, with a 3.5Gbps uplink, when the two technologies are aggregated.
WiFi 6 and WiFi 6e are also being added, as is Bluetooth Low Energy (BLE) and support for CD lossless audio. Finally, Qualcomm is adding something called a “trust management engine,” which is designed to help users secure confidential information. It will be compliant with Google’s Android Ready SE, which can be used for provisioning of Android keys, including digital keys for cars and homes, driving licenses and digital wallets. You will even be able to mint and store NFTs with Snapdragon 8, executives said.
The Snapdragon 8 Gen 1 supports iSIM, eliminating the need for a physical SIM card or SIM tray.

Qualcomm has yet to reveal whether updates to its Snapdragon Compute line of PC processors are en route. However, the company’s Snapdragon Tech Summit will run for another day.
This story has been updated with additional details at 6:34 PM. This post has been corrected to note that the official name of Qualcomm’s conference is the Snapdragon Tech Summit.
