On Wednesday, Qualcomm launched the Snapdragon 8cx Gen 3 processor platform for PCs, claiming that the chip will supply as much as 85 % extra efficiency than the prior technology.
That’s good, on condition that the pandemic severely undercut the worth proposition of Snapdragon-powered PCs—lengthy battery life and always-on cell connectivity—as workplace work life moved to the house workplace desk and sofa. Qualcomm’s Snapdragon 8cx Gen 2 arrived this past spring at in regards to the efficiency of the unique Microsoft Surface Laptop, although with considerably increased graphics chops.
Qualcomm’s aggressive efficiency predictions in regards to the Snapdragon 8cx Gen 3 are based mostly on its new course of shrink—from 7nm within the Gen 2 to a brand new, aggressive 5nm node in Gen 3. In all, Qualcomm believes that the chip will supply 85 % extra CPU efficiency than the prior technology, and 60 % further GPU efficiency. “We focused on really driving these features and capabilities in the mainstream PC segment,” stated Miguel Nunes, vp of product administration for Qualcomm, in a briefing with reporters.

Qualcomm additionally introduced the Snapdragon 7c+ Gen 3 compute platform for entry-tier PCs and Chromebooks. It’s constructed on a 6nm course of, with as much as 60 % sooner CPU efficiency and as much as 70 % GPU efficiency uplift. Like the Snapdragon 8cx Gen 3, the 7c+ might be 5G enabled.
Qualcomm isn’t disclosing the clock velocity of the Snapdragon 8cx Gen 3, neither is it disclosing the names of its built-in Kryo CPU, Adreno GPU, or Hexagon DSP—blame the brand new naming scheme adopted by its cell Snapdragon 8 processors. We do know thechip will help LPDDR4X-4266 reminiscence, NVMe SSDs, a pair of 4K exterior shows by way of DisplayPort, and 4K HDR@120fps video playback in {hardware}. Games can run at as much as 1080p at 120Hz, Qualcomm says.
According to Qualcomm’s Nunes, the Snapdragon 8cx Gen 3 doesn’t embrace any “efficiency” cores, simply “performance” and “prime” cores. Process shrinks supply a chance to save lots of energy, improve efficiency, or a combo of each; with the Snapdragon 8cx Gen 3, Qualcomm made the choice to dial up efficiency as excessive because it may.

Qualcomm’s processors run on the Arm instruction set, a platform that has struggled for years to maintain up with the normal x86 instruction set utilized by PC processors like AMD’s Ryzen and Intel’s Core chips. Last 12 months Microsoft added help for 64-bit directions to be added by way of emulation, hypothetically permitting most, if not all, of the PC’s conventional apps to run on prime of Arm. That compatibility has been baked proper into Windows 11, hopefully eradicating the compatibility problem from a shopper’s shopping for resolution.
Cameras, connectivity shine
Now, Qualcomm has to promote PC makers on its conventional strengths. In the smartphone market, the corporate’s new Snapdragon 8 Gen 1 cell processors can leverage the Hexagon DSP to use AI processing to images and video, creating synthetic bokeh and different results. The Snapdragon 8cx Gen 3 improves AI efficiency threefold, to 29 trillion operations per second (TOPS). (The 7c+ will supply 6.5 TOPS.) You can most likely anticipate to see the Snapdragon making use of its AI functionality to videoconferencing, with improved face detection, video backgrounds, sharper pictures, and so forth.
Granted, a few of Qualcomm’s cell strengths could seem a bit overpowered for the PC area. For instance, the built-in Spectra ISP helps as much as three cameras, with 24Mpixels of decision and 4K HDR. Convincing a PC maker to incorporate a 1080p (versus a 720p) webcam will seemingly be Qualcomm’s first problem. It might be Qualcomm’s post-processing expertise (autofocus, computerized white stability, and auto publicity—all options of the Snapdragon 8cx Gen 3) the place Qualcomm might have probably the most success. Still, Nunes postulated a world the place front- and rear-facing cameras may very well be used to create a hybrid atmosphere. The Snapdragon 8cx Gen 3 additionally leverages Qualcomm’s AI-driven audio noise suppression, battle-tested within the noisy world of smartphone calls.
“You’ll see better cameras show up,” Nunes promised. Qualcomm is working with the availability chain to get higher digital camera modules and pre-tune them for laptop computer makers, he stated.
It’s not clear whether or not the always-on cameras that Qualcomm talked about with its smartphone processors will make their technique to the laptop computer market. If they do, Nunes implied that it might be much less about laptops “seeing” customers, than it might be for presence detection.
Nunes additionally highlighted Qualcomm’s strengths in modems; PC makers may have three to select from, starting from the Snapdragon X65 5G modem (with 10Gbps downloads) to the Snapdragon X62 and X55 5G modems. The 8cx Gen 3 may even embrace the FastConnect 6900, with help for Wi-Fi 6e and its further 6GHz channel for high-speed wi-fi communication.
Nunes made the purpose that high-speed connectivity will assist offset any lack of native efficiency, too: cloud gaming companies like Microsoft’s Xbox Cloud Gaming (XCloud) rely upon high-speed, low-latency connectivity to render video games on a distant service.

Finally, the Snapdragon 8cx Gen 3 helps Microsoft’s secured-core PC initiative, together with help from Microsoft’s Pluton architecture, satisfying the Windows 11 TPM requirement. Features like runtime reminiscence encryption, secured cameras, and even GPS-powered trusted areas might assist Qualcomm win enterprise or authorities PCs. “We don’t believe security should be optional,” Nunes stated, an indirect criticism of the vPro structure Intel supplies as a part of its enterprise (however not shopper) platforms.
You’ll have to attend a bit for PCs based mostly on the Snapdragon 8cx Gen 3 and 7c+ to debut, nonetheless, as Qualcomm says they’ll launch within the first half of 2022. Nunes stated Qualcomm sees the present rollouts as a chance for Qualcomm to start out constructing out its infrastructure for numerous pricing tiers, prime to backside.
Later, Qualcomm will start to combine the Nuvia expertise that the corporate bought in January. That will roll out in 2023. According to Nunes, Qualcomm does personal a primary architectural license, which signifies that the corporate believes it could sustain with Apple’s M1.
“We can do everything that they can do,” Nunes stated.
