Qualcomm's latest mobile platform is the Snapdragon 636, positioned (at least numerically) between the Snapdragon 630 and 660 introduced earlier this year, and offering a very impressive set of features for mid-range devices - even reaching parity with the Snapdragon 800-series in some respects.
Qualcomm claims CPU performance gains of up to 40% from the Kryo 260 cores in the Snapdragon 636 compared to the ARM Cortex-A53 cores found in the Snapdragon 630, and the switch to Kryo brings the new Snapdragon 636 closer to the specs of the Snapdragon 660 - also an 8-core Kryo 260 design (though the higher-numbered platform does boast slightly higher clocks from its eight CPU cores at 2.2 GHz vs. 1.8 GHz from the 636).
The Snapdragon 636 also features the same X12 LTE modem found in the existing Snapdragon 630/660, which is capable of up to 600 Mbps download speeds (3 x 20 Hz carrier aggregation, 256-QAM) and 150 Mbps peak upload (2 x 20 Hz aggregation, 64-QAM).
Graphics duties are performed by the Adreno 509, and 18:9 FHD+ displays are supported. The Snapdragon 636 also includes the Hexagon 680 DSP (which we first saw in the Snapdragon 820) with Spectra 160 ISP for supported image capture "of up to 24 megapixels with zero shutter lag while supporting smooth zoom, fast autofocus and true-to-life colors for outstanding image quality", according to Qualcomm.
This new Snapdragon 636 also offers Qualcomm's Aqstic codec (another feature inherited from the 800-series) for high-resolution audio up to 24-bit/192 kHz PCM, along with dual-oscillator support (separate clock generators for 44.1 kHz and 48 kHz based sample rates!) and a 130dB dynamic range with a very low THD+N of -109dB.
To expand on what the Aqstic codec in the SD636 provides, the separate clock generators are a fascinating addition in a world where many codecs resample the common 44.1 kHz - pretty much all digital music at or below CD quality - to 48 kHz during playback. Having a proper 44.1 kHz clock means native playback without the interpolation and subsequent filtering required when altering the original signal to an incompatible sample rate.
The Snapdragon 636 - which is both "pin and software-compatible" with existing Snapdragon 660 and 630 mobile platforms, according to Qualcomm - is expected to ship to customers beginning in November.

Today Qualcomm took the covers off of an update to the Snapdragon 600 family of processors, now known as mobile platforms. The Snapdragon 660 and 630 Mobile Platforms are important products in the company’s portfolio as they address a larger segment of the consumer market than the premium-tier Snapdragon 800 while still offering performance and feature sets above the budget segments of the 400s. The Snapdragon 820 and 835 traditionally get all of the attention from media, the 600-series is at the heart of popular devices like the Sony Xperia X, Asus Zenfone 3 Ultra, HTC 10 Lifestyle and over 1000 more designs.
The biggest changes to both new platforms come in the form of LTE connectivity and GPU performance. In a bid to bring previously unseen capabilities to the 600-series of solutions, Qualcomm has taken the Snapdragon X12 LTE modem that shipped with the Snapdragon 820/821 SoC and integrated it on both the 660 and 630. This creates mainstream mobile platforms that can run Cat 12/13 modems and speeds as high as 600 Mbps downstream (3x carrier aggregation) and 150 Mbps upstream (2x carrier aggregation).
That is a significant move and should result in a massive amount of high speed devices saturating the market (and carriers’ networks) starting later this year. Along with that higher performance comes the same X12 feature set that we saw with Snapdragon 820/821 including adaptive antenna tuning capability (TruSignal) and dynamic signal quality adjustments for power efficiency optimizations.
The GPU performance of both the Snapdragon 660 and 630 get a boost over the previous competitors (653 and 626 respectively) though they do so with different Adreno implementations. The SD 660 uses the Adreno 512 GPU that offers up to 30% better performance compared to the Adreno 510 used on the SD 650 series. While we don’t have details yet on where that advantage comes from (clocks or core improvements), I have a feeling that much of it comes from improved frequencies. The Snapdragon 630 uses the Adreno 508 GPU, compared to the 506 from the SD 626 processor, and also claims to have a 30% performance advantage over the previous generation.

Google introduced its own premium smartphone today in the form of the Pixel and Pixel XL. Running Android Nougat 7.1, the Pixel smartphones will not only run the latest operating system but will be the new premium experience with the best Android features including Google Assistant and Smart Storage with unlimited cloud storage of photos and videos.
Google is definitely taking a greater interest in promoting Pixel than they have with even their Nexus devices. It will be interesting to see how other Android manufacturers react to this news but I would imagine that they are not all that pleased and Google will be in a similar position to Microsoft with its Surface products and Nvidia with it's Founder's Edition graphics cards.
Google's Pixel lineup includes the Pixel (5.6 x 2.7 x 0.2-0.3") and the Pixel XL (6 x 2.9 x 0.2-0.34") that wrap their respective 5-inch 1080p (441 PPI) and 5.5-inch 1440p (534 PPI) displays in a full aluminum and glass unibody design that will come in one of three colors: Very Black, Quite Silver and Really Blue. The smartphones feature curved corners and rounded edges with Corning Gorilla Glass 4 on the front and half of the back. Google has put a fingerprint sensor on the back of the phone and power, volume, three microphones, a USB-C port, and, yes, a 3.5mm audio jack.
There are both front and rear cameras and Google is claiming that the rear camera in particular is the best smartphone camera yet (with a DxOMark score of 89 points). The rear camera (which sits flush with the back of the phone) is rated at 12.3 MP with a f/2.0 aperture, and 1.55µm pixels. The camera further features an IMX378 sensor. electronic image stabilization, and both phase detection and laser auto focus. The Pixel can take HDR+ photos and videos at up to 4K30, 1080p120, or 720p240. Users can adjust white balance and use automatic exposure or auto focus locking. The front camera is less impressive at 8MP with fixed focus lens and f/2.4.
Internally, Google has opted to use the Qualcomm Snapdragon 821 (MSM8996) which is a 2+2 design that pairs two Kryo cores at 2.15 GHz with two Kryo cores at 1.6 GHz along with an Adreno 530 GPU, an impressive 4GB of LPDDR4 memory, and either 32GB or 128GB of internal storage which is regrettably non-expandable. The smartphones can tap into up to Category 11 LTE (Cat 9 in the US), 802.11ac Wi-Fi, Bluetooth 4.2, and NFC. Sensors include GPS, proximity, accelerometer, gyroscope, magnetometer, barometer, and hall sensors.
The Pixel features a 2,770 mAh battery and the Pixel Xl uses a slightly larger 3,450 mAh battery. In either case, Google rates the Pixel and Pixel XL at 13 hours and 14 hours of internet browsing and video playback respectively. Further, the batteries are able to be quick charged enough for up to "seven hours of use" after just 15 minutes of charging time using the included 18W USB-C charger.
Pricing works out to $649 for the 32GB Pixel, $749 for the 128GB Pixel, $769 for the 32GB Pixel XL, and $869 for the 128GB Pixel XL. In the US Google has partnered with Verizon for brick-and-mortar availability in addition to it being available on the Google store and other online retailers.
Google is banking a lot on these devices and asking a very premium price tag for the unlocked phones. It is certainly a gamble whether users will find the unique features enough to go with the Pixel over other flagships. What do you think about Google's increased interest in the smartphone space with the launch of its own hardware? How well will Pixel fit into the existing environment – will Pixel lead Android hardware and the OS to success or simply fragment it more?
I do like the look of the Pixel (especially the blue one) and the feature lists sounds good enough that maybe I could live without a removable battery and non-expandable storage (I'll be holding onto my old T-Mobile unlimited plan for as long as possible! heh). Pricing is a bit steep though and I think that will trip a lot of people up when searching for their next device.

Qualcomm is branching out with its SoCs to the auto industry with its upcoming line of Snapdragon 820 Automotive processors. The planned Snapdragon 820A and 820Am will begin sampling to auto makers and ODMs within the next few months and are aimed at in-car navigation, entertainment, dash displays, HUDs, and safety/driver assist systems.
Sharing a similar pedigree to the mobile-oriented Snapdragon 820, the new automotive series features Qualcomm's custom 64-bit "Kryo" CPU cores, an Adreno 530 GPU, Hexagon 680 DSP capable of processing up to eight car camera sensors, and 802.11ac Wi-Fi and Bluetooth wireless. The 802Am adds a Snapdragon X12 LTE modem which supports a maximum of 600 Mbps down and 150 Mbps upload speeds. Both chips are built on a 14nm manufacturing process and reportedly utilize a modular package and chip design that would allow auto manufacturers to save money on development costs of new vehicles by allowing upgraded hardware to be used with minimal software changes being necessary. End users aren't going to benefit from the modular nature, but the companies making the "infotainment" systems and those integrating them into new vehicles will.
Qualcomm envisions the 820 Automotive processors driving navigation and entertainment systems as well as being used for digital information displays such as dashboard readouts and windshield HUDs. The chips are also capable of limited driver assist functionality, though they won't be powering a self driving car all on their own yet. They can utilize always on sensors to provide collision alerts and 3D navigation that is aware of relative positioning (it can look for stop signs to assist a GPS which might not be accurate enough to tell you to turn at the correct time). Using between four and eight cameras, the 820Am is able to provide lane departure warnings, front collision warnings, traffic sign recognition, and object detection while backing up using machine learning / computer vision. That last bit is apparently powered by a Qualcomm technology called the Zeroth Machine Intelligency Platform.
There are rumors that Qualcomm will not be pursuing it's custom Kryo CPU cores beyond the Snapdragon 820, though I have my doubts that will happen. The higher margins of the auto industry and opportunity to sell even more chips that can be higher clocked may help to justify the higher R&D in the competitive mobile market. I'm interested to see if these once-mobile SoCs can live up to Qualcomm's promises for future vehicle tech.

Introduction and CPU Performance
We had a chance this week to go hands-on with the Snapdragon 820, the latest flagship SoC from Qualcomm, in a hardware session featuring prototype handsets powered by this new silicon. How did it perform? Read on to find out!
As you would expect from an all-new flagship part, the Snapdragon 820 offers improvements in virtually every category compared to their previous products. And with the 820 Qualcomm is emphasizing not only performance, but lower power consumption with claims of anywhere from 20% to 10x better efficiency across the components that make up this new SoC. And part of these power savings will undoubtedly come as the result of Qualcomm’s decision to move to a quad-core design with the 820, rather than the 8-core design of the 810.
So what exactly does comprise a high-end SoC like the Snapdragon 820? Ryan covered the launch in detail back in November (and we introduced aspects of the new SoC in a series of articles leading up to the launch). In brief, the Snapdragon 820 includes a custom quad-core CPU (Kryo), the Andreno 530 GPU, a new DSP (Hexagon 680), new ISP (Spectra), and a new LTE modem (X12). The previous flagship Snapdragon 810 used stock ARM cores (Cortex-A57, Cortex-A53) in a big.LITTLE configuration, but for various reasons Qualcomm has chosen not to introduce another 8-core SoC with this new product.
The four Kryo CPU cores found in the Snapdragon 820 can operate at speeds of up to 2.2 GHz, and since is half the number of the octo-core Snapdragon 810, the IPC (instructions per clock) of this new part will help determine how competitive the SD820's performance will be; but there’s a lot more to the story. This SoC design placed equal emphasis on all components therein, and the strategy with the SD820 seems to be leveraging the capability of the advanced signal processing (Hexagon 680) which should help offload the work to allow the CPU to work with greater efficiency, and at lower power.
