Shrout Research: Chromebook Platform Impacts Android App Performance

Please excuse the bit of self-promotion here. Oh, and disclaimer: Shrout Research and PC Perspective share management and ownership.

Based on testing done by Shrout Research and published in a paper this week, the introduction of Android applications on Chromebooks directly though the Play Store has added a new wrinkle into the platform selection decision. Android applications, unlike Chromebook native apps, have a heavy weight towards the Android phone and tablet ecosystem, with "defacto" optimization for the ARM-based processors and platforms that represent 98%+ of that market. As a result, there are some noticeable and noteworthy differences when running Android apps on Chromebooks powered by an ARM SoC and an Intel x86 SoC.

With that market dominance as common knowledge, all Android applications are developed targeting ARM hardware, for ARM processors. Compilers and performance profiling software has been built and perfected to improve the experience and efficiency of apps to run on ARMv7 (32-bit) and ARMv8 (64-bit) architectures. This brings to the consumer an improved overall experience, including better application compatibility and better performance.

Using a pair of Acer Chromebooks, the R11 based on the Intel Celeron N3060 and the R13 based on the MediaTek MT8173C, testing was done to compare the performance, loading times, and overall stability of various Android Play Store applications. A range of application categories were addressed including games, social, and productivity.

Through 19 tested Android apps we found that the ARM-powered R13 Chromebook performed better than the Intel-powered R11 Chromebook in 9 of them. In 8 of the apps tested, both platforms performed equally well. In 2 of the test applications, the Intel-powered system performed better (Snapchat and Google Maps).

The paper also touches on power consumption, and between these two systems, the ARM-based MediaTek SoC was using 11.5% less power to accomplish the same tasks.

Our testing indicates the Acer R13, using the ARM-powered processor, uses 11.5% less power on average in our 150 minutes of use through our education simulation. This is a significant margin and would indicate that with two systems equally configured, one with the MediaTek ARM processor and another with the Intel Celeron processor, the ARM-powered platform would get 11.5% additional usage time before requiring a charge. Based on typical Chromebook battery life (11 hours), the ARM system would see an additional 75 minutes of usability.

There is a lot more detail in the white paper on ShroutResearch.com, including a discussion about the impact that the addition of Android applications on Chromebooks might have for the market as whole:

...bringing a vast library of applications from the smart phone market to the Chromebook would create a combination of capabilities that would turn the computing spectrum sideways. This move alleviates the sustained notion that Chromebooks are connected-only devices and gives an instant collection of usable offline applications and tools to the market.

Add an ARM to your cortex

Researchers at the Center for Sensorimotor Neural Engineering are working on a way you can truly have SoC on the brain, partnering with ARM to develop chips which can be implanted in the brain.  The goal is not to grant you a neural interface nor add a couple of petabytes to your long term memory but to help treat people suffering from paralysis due to stroke or other damage to the brain.  There is the small problem of heat, brain tissue will be much more susceptible to damage from implanted devices than an organ in the torso; a pacemaker has space in which to dissipate excess heat.  We are still a long way off but you can read up on the current state of the research by following the links at The Inquirer.

The $100 Pinebook; usable as a laptop?

Subject: General Tech | May 1, 2017 - 01:54 PM |
Tagged: pinebook, arm, Cortex A53. ubuntu

Pinebooks are built around the same ARM Cortex A53 that the kickstarted Pine board utilized, but instead of being a Raspberry like board, it is a built to order laptop.  The 11.6" model is $89 and the 14" model will cost you $99.  The screen is 1366×768, it comes with a 640x480 camera as well as a pair of USB ports, audio, miniSD and miniHDMI connectors.  Hack a Day ordered one and found that in some ways this is still a work in progress as there are issues with some of the outputs which may soon be addressed in an update to the Ubuntu MATE 16.04 OS it runs.  Still a laptop for less than $100 is impressive and might be worth tinkering with, take a more detailed look here.

"The Pine A64 was a 64-bit Quad-Core Single Board Computer which was kickstarted at the tail end of 2015 for delivery in the middle of 2016. Costing just $15, and hailed as a “Raspberry Pi killer,” the board raised $1.7 million from 36,000 backers. It shipped to its backers to almost universally poor reviews."

A call to ARM in the server room

Subject: General Tech | March 21, 2017 - 12:23 PM |
Tagged: server, SBSA, arm

As we mentioned last week, Qualcomm's new Centriq 2400 Platform will run Microsoft server operating systems on ARM chips, however there are those who believe it is already too late for that to save Microsoft's hold on the data centre.  A few years ago ARM started work on developing what they called Server Base System Architecture, essentially creating a standardized way in which any OS can communicate effectively with an ARM chip, the same sort of standardization which originally won the server room for x86 based chips.  With ARM's DynamIQ Technology, which Josh discusses in depth, just around the corner their hardware is also becoming more attractive.  Pop by The Register for more details on this possible industry sea change.

"Cutting to the heart of it, it doesn't actually matter if Microsoft releases Windows Server for ARM. Windows isn't the future and even Microsoft knows it. The upcoming availability of SQL server on Linux is all the proof we need that the game is over and, in the data centre at least, Microsoft didn't win."

New "Fabric" for ARM

It is not much of a stretch to say that ARM has had a pretty impressive run for the past 10 years since we started paying attention to the company from a consumer point of view.  It took 22 years for ARM to power 50 billion chips that had been shipped.  It took another 4 years to hit the next 50 billion.  Now ARM expects to ship around 100 billion chips in the next four years.
arm_01.png
 
Last year we saw the introduction of multiple technologies from ARM in the shape of the latest Cortex-A CPUs and a new generation of Mali GPUs.  ARM has been near the forefront of applying their designs to the latest, cutting edge process technologies offered by Samsung and TSMC.  This change of pace has been refreshing considering that a few years ago they would announce a new architecture and expect to see it in new phones and devices about 3 years from that point.  Intel attempted a concerted push into mobile and ARM responded by tightening up their portfolio and aggressively pushing release dates.
 
This year appears no different for ARM as we expect new technologies to be announced again later this year that will update their offerings as well as process technology partnerships with the major pure-play foundries.  The first glimpse of what we can expect is ARM's announcement today of their DynamIQ technology.

DynamIQ can be viewed as a portfolio of technologies that will power the next generation of ARM CPUs, GPUs, and potentially accelerators.  This encompasses power delivery, power control, connectivity, and topologies.
 
 

SoftBank Plans To Sell 25% of ARM Holdings To Vision Fund

Subject: General Tech, Processors | March 11, 2017 - 10:02 PM |
Tagged: softbank, investments, business, arm

Japanese telecom powerhouse SoftBank, which recently purchased ARM Holdings for $32 billion USD is reportedly in talks to sell off a 25% stake in its new subsidiary to a new investment fund. Specifically, the New York Times cites a source inside SoftBank familiar with the matter who revealed that SoftBank is in talks with the Vision Fund to purchase a stake in ARM Holdings worth approximately $8 billion USD.

ARM at a glance.png

The $100 billion Vision Fund is an investment fund started by SoftBank founder Masayoshi Son with a goal of investing in high growth technology start-ups and major technology IP holders. The fund is currently comprised of investments from SoftBank worth $25 billion, $45 billion from Saudi Arabia (via Saudi Arabia Public Investment Fund), and minor investments from Apple and Oracle co-founder Lawrence Ellison. The fund is approximately 75% of the way to its $100 billion funding goal with the state owned Mubadala Development investment company in Abu Dhabi and the Qatari government allegedly interested in joining the fund. The Vision Fund is based in the UK and led by SoftBank's Head of Strategic Finance Rajeev Mistra (Investment bankers Nizar al-Bassam and Dalin Ariburnu formerly of Deutsche Bank and Goldman Sachs respectively are also involved.)

It is interesting that SoftBank plans to sell off such a large stake in ARM Holdings so soon after purchasing the company (the sale finalized only six months ago), but it may be a move to entice investors to the investment fund which SoftBank is a part of to further diversify its assets. The more interesting question is the political and regulatory reaction to this news and what it will mean for ARM and its IP to have even more countries controlling it and its direction(s). I do not have the geopolitical acumen to speculate on whether this is a good or bad thing (heh). It does continue the trend of countries outside of the US increasing their investments in established technology companies with lots of IP (wether US based or not) as well as new start ups. New money entering this sector is likely overall good though, at least for the companies involved heh.

I guess we will just have to wait and see if the sale completes and where ARM goes from there! What are your thoughts on the SoftBank sale of a quarter stake in ARM?

ARMing the Cloud; Qualcomm's Centriq 2400 Platform will power Microsoft Azure instances

Subject: General Tech, Systems | March 8, 2017 - 12:20 PM |
Tagged: qualcomm, OCP, microsoft, falkor, centriq 2400, azure, arm, 10nm

Last December Qualcomm announced plans to launch their Centriq 2400 series of platforms for data centres, demonstrating Apache Spark and Hadoop on Linux as well as a Java demo.  They announced a 48 Core design based on ARM v8 and fabbed with on Samsung's 10nm process, which will compete against Intel's current offerings for the server room.

Today marks the official release of the Qualcomm Falkor CPU and Centriq 2400 series of products, as well as the existence of a partnership with Microsoft which may see these products offered to Azure customers.  Microsoft has successfully configured a version of Windows Server to run on these new chips, which is rather big news for customers looking for low powered hosting solutions running a familiar OS.  The Centriq 2400 family is compliant with Microsoft's Project Olympus architecture, used by the Open Compute Project Foundation to offer standardized building blocks upon which you can design a data centre from scratch or use as an expansion plan.

Enough of the background, we are here for the specifications of the new platform and what can be loaded onto a Centriq 2400.  The reference motherboard supports SOCs of up to 48 cores, with both single and dual socket designs announced.  Each SOC can support up to six channels of DDR4 in either single or dual channel configurations with a maximum of 768GB installed.  Falkor will offer 32 lanes of PCIe 3.0, eight SATA ports and a GbE ethernet port as well as USB and a standard 50Gb/s NIC.  NVMe is supported, one design offers 20 NVMe drives with a PCIe 16x slot but you can design the platform to match your requirements.  Unfortunately they did not discuss performance during their call, nor any suggested usage scenarios.  We expect to hear more about that during the 2017 Open Compute Platform US Summit, which starts today.

The submission of the design to Open Compute Project ensures a focus on compatibility and modularity and allows a wide variety of designs to be requested and networked together.  If you have a need for HPC performance you can request a board with an HPC GPU such as a FirePro or Tesla, or even drop in your own optimized FPGA.  Instead of opting for an impressive but expensive NVME storage solution, you can modify the design to accommodate 16 SATA HDDs for affordable storage.

Qualcomm have already announced Windows 10 support on their Snapdragon, but the fact that Microsoft are internally running Windows Server on an ARM v8 based processor is much more impressive.  Intel and AMD have long held reign in the server room and have rightfully shrugged of the many times in which companies have announced ARM based servers which will offer more power efficient alternatives.  Intel have made huge advances at creating low power chips for the server room; AMD's recently announced Naples shows their intentions to hold their market share as well.

If the submission to the OPC succeeds then we may see the first mainstream ARM based servers appear on the market.  Even if the Windows Server instances remain internal to Microsoft, the Centriq series will support Red Hat, CentOS, Canonical and Ubuntu as well as both GCC and LLVM compilers.

(click to seriously embiggen)

ARM may finally have reached the server market after all these years and it will be interesting to see how they fare.  AMD and Intel have both had to vastly reduce the power consumption of their chips and embrace a diametrically opposite design philosophy; instead of a small number of powerful chips, servers of the future will consist of arrays of less powerful chips working in tandem.  ARM has had to do the opposite, they are the uncontested rulers of low powered chips but have had to change their designs to increase the processing capabilities of their chips in order to produce an effective product for the server room.  

Could Qualcomm successful enter the server room; or will their ARMs not have the necessary reach?
