The upcoming Snapdragon 820 is shaping up to be a formidable SoC after the disappointing response to the previous flagship, the Snapdragon 810, which was in far fewer devices than expected for reasons still shrouded in mystery and speculation. One of the biggest aspects of the upcoming 820 is Qualcomm’s new X12 modem, which will provide the most advanced LTE connectivity seen to date when the SoC launches. The X12 features CAT 12 LTE downlink speeds for up to 600 Mbps, and CAT 13 on the uplink for up to 150 Mbps.

LTE connectivity isn’t the only new thing here, as we see from this slide there is also tri-band Wi-Fi supporting 2x2 MU-MIMO.


“This is the first publicly announced processor for use in mobile devices to support LTE Category 12 in the downlink and Category 13 in the uplink, providing up to 33 percent and 200 percent improvement over its predecessor’s download and upload speeds, respectively.”

The specifications for this new modem are densely packed:

  • Cat 12 (up to 600 Mbps) in the downlink
  • Cat 13 (up to 150 Mbps) in the uplink
  • Up to 4x4 MIMO on one downlink LTE carrier
  • 2x2 MU-MIMO (802.11ac)
  • Multi-gigabit 802.11ad
  • LTE-U and LTE+Wi-Fi Link Aggregation (LWA)
  • Next Gen HD Voice and Video calling over LTE and Wi-Fi
  • Call Continuity across Wi-Fi, LTE, 3G, and 2G
  • RF front end innovations
  • Advanced Closed Loop Antenna Tuner
  • Qualcomm RF360™ front end solution with CA
  • Wi-Fi/LTE antenna sharing

Rumored phones that could end up running the Snapdragon 820 with this X12 modem include the Samsung Galaxy S7 and around 30 other devices, though final word is of course pending on shipping hardware.

Qualcomm Announces Quick Charge 3.0

Qualcomm has announced Quick Charge 3.0, the latest iteration of their fast battery charging technology. The new version is said to not only further improve battery charging times, but also better maintain battery health and reduce temperatures.

One of the biggest issues with fast battery charging is the premature failure of the battery cells; something my first Nexus 6 (which was replaced due to a bad battery) can attest to. The new 3.0 standard adds "Battery Saver Technology" (BST) which constantly varies the current delivery rate based on what the battery can safely accept, thus preventing damage to the cells. This new version of Quick Charge also claims to offer lower temps while charging, which could be partly the result of this variable current delivery.

The other change comes from "Intelligent Negotiation for Optimum Voltage" (INOV), which can vary the voltage delivery anywhere from 3.6V to 20V in 200mV increments depending on the device's negotiated connection. INOV will allow Quick Charge 3.0 to charge a full 2x faster than the original Quick Charge 1.0 (it's 1.5x faster than QC 2.0), and 4x over standard USB charging as it provides up to 60W to compatible devices.

This new Quick Charge 3.0 technology will be available soon with devices featuring upcoming Qualcomm SoCs such as the Snapdragon 820.

A third primary processor

As the Hot Chips conference begins in Cupertino this week, Qualcomm is set to divulge another set of information about the upcoming Snapdragon 820 processor. Earlier this month the company revealed details about the Adreno 5xx GPU architecture, showcasing improved performance and power efficiency while also adding a new Spectra 14-bit image processor. Today we shift to what Qualcomm calls the “third pillar in the triumvirate of programmable processors” that make up the Snapdragon SoC. The Hexagon DSP (digital signal processor), introduced initially by Qualcomm in 2004, has gone through a massive architecture shift and even programmability shift over the last 10 years.


Qualcomm believes that building a balanced SoC for mobile applications is all about heterogeneous computing with no one processor carrying the entire load. The majority of the work that any modern Snapdragon processor must handle goes through the primary CPU cores, the GPU or the DSP. We learned about upgrades to the Adreno 5xx series for the Snapdragon 820 and we are promised information about Kryo CPU architecture soon as well. But the Hexagon 600-series of DSPs actually deals with some of the most important functionality for smartphones and tablets: audio, voice, imaging and video.

Interestingly, Qualcomm opened up the DSP to programmability just four years ago, giving developers the ability to write custom code and software to take advantages of the specific performance capabilities that the DSP offers. Custom photography, videography and sound applications could benefit greatly in terms of performance and power efficiency if utilizing the QC DSP rather than the primary system CPU or GPU. As of this writing, Qualcomm claims there are “hundreds” of developers actively writing code targeting its family of Hexagon processors.


The Hexagon DSP in Snapdragon 820 consists of three primary partitions. The main compute DSP works in conjunction with the GPU and CPU cores and will do much of the heavy lifting for encompassed workloads. The modem DSP aids the cellular modem in communication throughput. The new guy here is the lower power DSP in the Low Power Island (LPI) that shifts how always-on sensors can communicate with the operating system.

Qualcomm Introduces Adreno 5xx Architecture for Snapdragon 820

Despite the success of the Snapdragon 805 and even the 808, Qualcomm’s flagship Snapdragon 810 SoC had a tumultuous lifespan.  Rumors and stories about the chip and an inability to run in phone form factors without overheating and/or draining battery life were rampant, despite the company’s insistence that the problem was fixed with a very quick second revision of the part. There are very few devices that used the 810 and instead we saw more of the flagship smartphones uses the slightly cut back SD 808 or the SD 805.

Today at Siggraph Qualcomm starts the reveal of a new flagship SoC, Snapdragon 820. As the event coinciding with launch is a graphics-specific show, QC is focusing on a high level overview of the graphics portion of the Snapdragon 820, the updated Adreno 5xx architecture and associated designs and a new camera image signal processor (ISP) aiming to improve quality of photos and recording on our mobile devices.


A modern SoC from Qualcomm features many different processors working in tandem to impact the user experience on the device. While the only details we are getting today focus around the Adreno 530 GPU and Spectra ISP, other segments like connectivity (wireless), DSP, video processing and digital signal processing are important parts of the computing story. And we are well aware that Qualcomm is readying its own 64-bit processor architecture for the Kryo CPU rather than implementing the off-the-shelf cores from ARM used in the 810.

We also know that Qualcomm is targeting a “leading edge” FinFET process technology for SD 820 and though we haven’t been able to confirm anything, it looks very like that this chip will be built on the Samsung 14nm line that also built the Exynos 7420.

But over half of the processing on the upcoming Snapdragon 820 fill focus on visual processing, from graphics to gaming to UI animations to image capture and video output, this chip’s die will be dominated by high performance visuals.

Qualcomm’s lists of target goals for SD 820 visuals reads as you would expect: wanting perfection in every area. Wouldn’t we all love a phone or tablet that takes perfect photos each time, always focusing on the right things (or everything) with exceptional low light performance? Though a lesser known problem for consumers, having accurate color reproduction from capture, through processing and to the display would be a big advantage. And of course, we all want graphics performance that impresses and a user interface that is smooth and reliable while enabling NEW experience that we haven’t even thought of in the mobile form factor. Qualcomm thinks that Snapdragon 820 will be able to deliver on all of that.

Qualcomm’s GPU History

Despite its market dominance, Qualcomm may be one of the least known contenders in the battle for the mobile space. While players like Apple, Samsung, and even NVIDIA are often cited as the most exciting and most revolutionary, none come close to the sheer sales, breadth of technology, and market share that Qualcomm occupies. Brands like Krait and Snapdragon have helped push the company into the top 3 semiconductor companies in the world, following only Intel and Samsung.

Founded in July 1985, seven industry veterans came together in the den of Dr. Irwin Jacobs’ San Diego home to discuss an idea. They wanted to build “Quality Communications” (thus the name Qualcomm) and outlined a plan that evolved into one of the telecommunications industry’s great start-up success stories.

Though Qualcomm sold its own handset business to Kyocera in 1999, many of today’s most popular mobile devices are powered by Qualcomm’s Snapdragon mobile chipsets with integrated CPU, GPU, DSP, multimedia CODECs, power management, baseband logic and more.  In fact the typical “chipset” from Qualcomm encompasses up to 20 different chips of different functions besides just the main application processor. If you are an owner of a Galaxy Note 4, Motorola Droid Turbo, Nexus 6, or Samsung Galaxy S5, then you are most likely a user of one of Qualcomm’s Snapdragon chipsets.


Qualcomm’s GPU History

Before 2006, the mobile GPU as we know it today was largely unnecessary. Feature phones and “dumb” phones were still the large majority of the market with smartphones and mobile tablets still in the early stages of development. At this point all the visual data being presented on the screen, whether on a small monochrome screen or with the color of a PDA, was being drawn through a software renderer running on traditional CPU cores.

But by 2007, the first fixed-function, OpenGL ES 1.0 class of GPUs started shipping in mobile devices. These dedicated graphics processors were originally focused on drawing and updating the user interface on smartphones and personal data devices. Eventually these graphics units were used for what would be considered the most basic gaming tasks.

There have been many stories about Qualcomm's difficulties lately, from the court case with NVIDIA to Samsung and LG not using their Snapdragon 810 for their new smartphones.  Qualcomm has struck back at the speculations about problems with this chip that rose from these decisions, pointing out that Microsoft, Xiaomi, Motorola and Sony will all be releasing devices with the Snapdragon 810 in the near future.  LG put in their two cents as well, pointing out their decision to use the 808 chip was made over a year ago and they are still planning on utilizing the next generation Snapdragon 820 in the future, not to mention that they use the 810 in their G Flex 2.  Samsung has also shown their belief in Qualcomm's products considering they will be fabbing the 820.  You can see a short video of an interview with Qualcomm about this topic over at The Register.


"QUALCOMM HAS DEBUNKED chatter that LG ditched its octa-core Snapdragon 810 chip for the G4 owing to overheating problems."

Not only has the NVIDIA sueball pitch been judged to be in play and will continue to run but now according to news The Register has heard Samsung may be using their own in-house ARM processors for their next products.  The rumour is that they have spend four years developing an ARM processor from the ground up which will make it much less likely that Qualcomm will be able to sell their next generation 64 bit Snapdragon Kyro processor to Samsung, which is after all a modified ARM v8-a chip as opposed to a custom built processor.  Qualcomm does have other customers than Samsung, including HTC, Amazon and LG who might be interested in the new Snapdragon 820 but it does look bleak for their next generation processor.  The only leverage Qualcomm has now is that Samsung will likely be the ones fabbing many of the new Snapdragon 820's, perhaps they can strike a deal for some lower cost mobile devices once Kyro matures.

A judge has ruled that six of the seven patent disputes that NVIDIA has filed are valid and will proceed to court for judgment.  These patents involve the use of graphics coprocessors in mobile devices and have been judged to be worded in such a way that it does not matter if those GPUs are ARM, Imagination Technologies or Qualcomm.  This is not the end of the dispute, merely a pretrial to see if the claims are valid and worth going to trial.  Of course Qualcomm and Samsung dispute NVIDIA's claims and in Samsung's case they have already launched a counter suit claiming NVIDIA has violated six of their own patents.  You can read about the history of the latest legal battle in the tech world as well as today's judgment over at The Register.


"Nvidia has won an important early victory in its ongoing patent litigation against Qualcomm and Samsung, with a judge in the US International Trade Commission ruling in Nvidia's favor as to the language of the disputed patents."
