Qualcomm Announces X16 Modem Featuring Gigabit LTE

Subject: Mobile | February 12, 2016 - 09:26 PM |
Tagged: X16 modem, qualcomm, mu-mimo, modem, LTE, Gigabit LTE, FinFET, Carrier Aggregation, 14nm

Qualcomm’s new X16 LTE Modem is the industry's first Gigabit LTE chipset to be announced, achieving speeds of up to 1 Gbps using 4x Carrier Aggregation. The X16 succeeds the recently announced X12 modem, improving on the X12's 3x Carrier Aggregation and moving from LTE CAT 12 to CAT 16 on the downlink, while retaining CAT 13 on the uplink.

"In order to make a Gigabit Class LTE modem a reality, Qualcomm added a suite of enhancements – built on a foundation of commercially-proven Carrier Aggregation technology. The Snapdragon X16 LTE modem employs sophisticated digital signal processing to pack more bits per transmission with 256-QAM, receives data on four antennas through 4x4 MIMO, and supports for up to 4x Carrier Aggregation — all of which come together to achieve unprecedented download speeds."

Gigabit speeds are only possible if multiple data streams are connected to the device simultaneously, and with the new X16 modem such aggregation is performed using LTE-U and LAA.

What does all of this mean? Aggregation is a term you'll see a lot as we progress into the next generation of cellular data technology, and with the X16 Qualcomm is emphasizing carrier over link aggregation. Essentially Carrier Aggregation works by combining the carrier LTE data signal (licensed, high transmit power) with a shorter-range, shared spectrum (unlicensed, low transmit power) LTE signal. When the signals are combined at the device (i.e. your smartphone), significantly better throughput is possible with this larger (aggregated) data ‘pipe’.

Qualcomm lists the four main options for unlicensed LTE deployment as follows:

  • LTE-U: Based on 3GPP Rel. 12, LTE-U targets early mobile operators deployments in USA, Korea and India, with coexistence tests defined by LTE-U forum
  • LAA: Defined in 3GPP Rel. 13, LAA (Licensed Assisted Access) targets deployments in Europe, Japan, & beyond.
  • LWA: Defined in 3GPP Rel. 13, LWA (LTE - Wi-Fi link aggregation) targets deployments where the operators already has carrier Wi-Fi deployments.
  • MulteFire: Broadens the LTE ecosystem to new deployment opportunities by operating solely in unlicensed spectrum without a licensed anchor channel

The X16 is also Qualcomm’s first modem to be built on 14nm FinFet process, which Qualcomm says is highly scalable and will enable the company to evolve the modem product line “to address an even wider range of product, all the way down to power-efficient connectivity for IoT devices.”

Qualcomm has already begun sampling the X16, and expects the first commercial products in the second half of 2016.

CES 2016: Qualcomm Snapdragon 820A SoCs To Drive Future Car PCs

Subject: General Tech, Mobile | January 7, 2016 - 11:55 PM |
Tagged: snapdragon 820A, snapdragon 820, qualcomm, LTE, Kryo, adreno

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.

Qualcomm Rebrands Two Snapdragon SoCs

Subject: Mobile | December 18, 2015 - 12:06 PM |
Tagged: snapdragon, qualcomm

The mobile processors that were previously known as the Snapdragon 618 and the Snapdragon 620 are now known as Snapdragon 650 and Snapdragon 652, respectively. This is not how we typically see products rebranded. Normally, such as the desktop GPU market, individual products are carried between generations, and their model number is incremented to reflect that. This case is the exact opposite: Qualcomm feels that the new products are numbered too similar to existing models, so they're widening the gap between them.

An SoC is only useful if it is installed in a compelling device, though. While I would hope that these sorts of branding changes influence consumers more than device manufacturers, there exists a part of me that wonders how much this rebranding will affect their amount of design wins. You would think that bumping a model number up a few digits wouldn't affect experimentation at Samsung, LG, or other phone companies. Yet, it might, and that would be interesting to see. Either way, it should affect the semi-enthusiast phone users who buy based on breakdowns of tech specs.

It's getting crowded in the server room already and Qualcomm wants in

Subject: General Tech | December 11, 2015 - 05:16 PM |
Tagged: server, qualcomm

AMD and Intel have been fighting it out in the server room for a while and have had to shift their tactics towards more efficient processors which merely sip at power compared to the first decade of this century.  Coming from the other direction IBM and ARM design teams have been increasing the power of their chips and their ability to work together to match AMD and Intel's performance while still trying to maintain a lead on power efficiency.  Now, according to what DigiTimes has been hearing, Qualcomm is ready to take advantage of its ARM license to officially move into the server market.  Their initial design will sport 24 cores, provide support for VM environments and will be Linux compatible.  Keep an eye on Xilinx and Mellanox Technologies as they were the companies who have announced plans to release products based on Qualcomm's designs.

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!

820_2.png

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.

820_1.png

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.

Cat 12 Modem, Wi-Fi Adaptive Calling

If you have been following PC Perspective over the last several months it would be hard to miss news about the upcoming release of Qualcomm's latest flagship SoC for smartphones and tablets, the Snapdragon 820. Beginning in early August with discussion of the Adreno 5xx GPU architecture, followed by information covering the Hexagon 680 DSP (digital signal processor) and then details on the LTE modem in the SoC (the X12), and ending with information on the Kryo CPU cores, the release of the Snapdragon 820 processor has been drawn out if nothing else. 

01.jpg

The emphasis on distribution of data was likely at attempt to rebuild trust with the enthusiast consumer, media and even the OEMs, as the launch of the Snapdragon 810 was troubled by overheating concerns and second revisions. Several high impact flagship smartphone used the SoC, including the LG G4 (correction: G4 shipped with the Snapdragon 808, while the HTC One M9, OnePlus 2, Sony Xperia Z5 and others use the 810) but with Samsung moving away from Qualcomm parts to its own designs, the processor didn't see nearly the ubiquitous adoption that we had expected and witnessed in previous generations.

slide1.jpg

Qualcomm invited some media and analysts out to New York this week to take the cover off of the Snapdragon 820 completely, at least as far as features are concerned. We still were not able to get to the meat of the details surrounding the CPU / Kryo implementation or architectural improvements, but we are promised those would be coming closer to product availability in 2016. Instead, Qualcomm wanted to show off the consumer benefits that phones and tablets based on Snapdragon 820 could feature (based on OEM implementation); that means lots of demos, lots of time with product and feature managers.

A 24-core design based on 64-bit ARM architecture has reached the prototype phase, in a large LGA package resembling an Intel Xeon CPU.

From the report published by PC World:

"Qualcomm demonstrated a pre-production chip in San Francisco on Thursday. It's a purpose-built system-on-chip, different from its Snapdragon processor, that integrates PCIe, storage and other features. The initial version has 24 cores, though the final part will have more, said Anand Chandrasekher, Qualcomm senior vice president."

Qualcomm built servers as proof-of-concept with this new processor, "running a version of Linux, with the KVM hypervisor, streaming HD video to a PC. The chip was running the LAMP stack - Linux, the Apache Web server, MySQL, and PHP - and OpenStack cloud software," according to PC World. The functionality of this design demonstrate the chip's potential to power highly energy-efficient servers, making an obvious statement about the potential cost savings for large data companies such as Google and Facebook.
