Another Boring Presentation...?

In my old age I am turning into a bit of a skeptic.  It is hard to really blame a guy; we are surrounded by marketing and hype, both from inside companies and from their fans.  When I first started to listen in on AMD’s Core Innovation Update presentation, I was not expecting much.  I figured it would be a rehash of the past year, more talk about Mullins/Beema, and some nice words about some of the upcoming Kaveri mobile products.

I was wrong.

AMD decided to give us a pretty interesting look at what they are hoping to accomplish in the next three years.  It was not all that long ago that AMD was essentially considered road kill, and there was a lot of pessimism that Rory Read and Co. could turn AMD around.  Now after a couple solid years of growth, a laser-like focus on product development based on the IP strengths of the company, and a pretty significant cut of the workforce, we are seeing an AMD that is vastly different from the one that Dirk Meyers was in charge of (or Hector Ruiz for that matter).  Their view for the future takes a pretty significant turn from where AMD was even 8 years ago.  x86 certainly has a future for AMD, but the full-scale adoption of the ARM architecture looks to be what finally differentiates this company from Intel.

Look, I’m Amphibious!

AMD is not amphibious.  They are working on being ambidextrous.  Their goal is not only to develop and sell x86 based processors, but also be a prime moving force in the ARM market.  AMD has survived against a very large, well funded, and aggressive organization for the past 35 years.  They believe their experience here can help them break into, and thrive within, the ARM marketplace.  Their goals are not necessarily to be in every smartphone out there, but they are leveraging the ARM architecture to address high growth markets that have a lot of potential.

There are really two dominant architectures in the world with ARM and x86.  They power the vast majority of computing devices around the world.  Sure, we still have some Power and MIPS implementations, but they are dwarfed by the combined presence of x86 and ARM in modern devices.  The flexibility of x86 allows it to scale from the extreme mobile up to the highest performing clusters.  ARM also has the ability to scale in performance from handhelds up to the server world, but so far their introduction into servers and HPC solutions has been minimal to non-existent.  This is an area that AMD hopes to change, but it will not happen overnight.  A lot of infrastructure is needed to get ARM into that particular area.  Ask Intel how long it took for x86 to gain a handhold in the lucrative server and workstation markets.

AMD Shows Off ARM-Based Opteron A1100 Server Processor And Reference Motherboard

Subject: Processors | May 8, 2014 - 12:26 AM |
Tagged: TrustZone, server, seattle, PCI-E 3.0, opteron a1100, opteron, linux, Fedora, ddr4, ARMv8, arm, amd, 64-bit

AMD showed off its first ARM-based “Seattle” processor running on a reference platform motherboard at an event in San Francisco earlier this week. The new chip, which began sampling in March, is slated for general availability in Q4 2014. The “Seattle” processor will be officially labeled the AMD Opteron A1100.

During the press event, AMD demonstrated the Opteron A1100 running on a reference design motherboard (the Seattle Development Platform). The hardware was used to drive a LAMP software stack including an ARM optimized version of Linux based on RHEL, Apache 2.4.6, MySQL 5.5.35, and PHP 5.4.16. The server was then used to host a WordPress blog that included stream-able video.

Of course, the hardware itself is the new and interesting bit and thanks to the event we now have quite a few details to share.

The Opteron A1100 features eight ARM Cortex-A57 cores clocked at 2.0 GHz (or higher). AMD has further packed in an integrated memory controller, TrustZone encryption hardware, and floating point and NEON video acceleration hardware. Like a true SoC, the Opteron A1100 supports 8 lanes of PCI-E 3.0, eight SATA III 6Gbps ports, and two 10GbE network connections.

The Seattle processor has a total of 4MB of L2 cache (each pair of cores shares 1MB of L2) and 8MB L3 cache that all eight cores share. The integrated memory controller supports DDR3 and DDR4 memory in SO-DIMM, unbuffered DIMM, and registered ECC RDIMM forms (only one type per motherboard) enabling the ARM-based platform to be used in a wide range of server environments (enterprise, SMB, and home servers et al).

AMD has stated that the upcoming Opteron A1100 processor delivers between two and four times the performance of the existing Opteron X series (which uses four x86 Jaguar cores clocked at 1.9 GHz). The A1100 has a 25W TDP and is manufactured by Global Foundries. Despite the slight increase in TDP versus the Opteron X series (the Opteron X2150 is a 22W part), AMD claims the increased performance results in notable improvements in compute/watt performance.

AMD has engineered a reference motherboard though partners will also be able to provide customized solutions. The combination of reference motherboard and ARM-based Opteron A1100 is known at the Seattle Development Platform. This reference motherboard features four registered DDR3 DIMM slots for up to 128GB of memory, eight SATA 6Gbps ports, support for standard ATX power supplies, and multiple PCI-E connectors that can be configured to run as a single PCI-E 3.0 x8 slot or two PCI-E 3.0 x4 slots.

The Opteron A1100 is an interesting move from AMD that will target low power servers. the ARM-based server chip has an uphill battle in challenging x86-64 in this space, but the SoC does have several advantages in terms of compute performance per watt and overall cost. AMD has taken the SoC elements (integrated IO, memory, companion processor hardware) of the Opteron X series and its APUs in general, removed the graphics portion, and crammed in as many low power 64-bit ARM cores as possible. This configuration will have advantages over the Opteron X CPU+GPU APU when running applications that use multiple serial threads and can take advantage of large amounts of memory per node (up to 128GB). The A1100 should excel in serving up files and web pages or acting as a caching server where data can be held in memory for fast access.

I am looking forward to the launch as the 64-bit ARM architecture makes its first major inroads into the server market. The benchmarks, and ultimately software stack support, will determine how well it is received and if it ends up being a successful product for AMD, but at the very least it keeps Intel on its toes and offers up an alternative and competitive option.

Building a SkyBridge in 64 bits, between ARM and x86

Subject: General Tech | May 6, 2014 - 02:31 PM |
Tagged: amd, arm, project skybridge, k12

The Register has put together an overview of what AMD discussed yesterday about the K12 processor and Project Skybridge.  The most impressive feat is Project SkyBridge; with the license AMD now has to develop ARMv8 architecture they will be creating pin compatible ARM and x86 SoCs, so you can choose which you want to drop in your server and can easily change your mind any time in the future.  The more traditional 64-bit x86 processors will be "Puma+" cores while the ARM SoCs will be 64-bit A57s, and will not only be fully HSA compliant but will be able to run Android.  They also delve into AMD's upcoming strategy to remain a valid contender in the silicon ring, read on to get a glimpse into Papermaster's brain.

ARM Claims x86 Android Binary Translation on Intel SoC Hurting Efficiency

Subject: Processors, Mobile | April 30, 2014 - 07:06 PM |
Tagged: Intel, clover trail, Bay Trail, arm, Android

While we are still waiting for those mysterious Intel Bay Trail based Android tablets to find their way into our hands, we met with ARM today to discuss quite few varying topics. One of them centered around the cost of binary translation - the requirement to convert application code compiled for one architecture and running it after conversion on a different architecture. In this case, running native ARMv7 Android applications on an x86 platform like Bay Trail from Intel.

translate1.jpg

Based on results presented by ARM, so take everything here in that light, more than 50% of the top 250 applications in the Android Play Store require binary translation to run. 23-30% have been compiled to x86 natively, 20-21% run through Dalvik and the rest have more severe compatibility concerns. That paints a picture of the current state of Android apps and the environment in which Intel is working while attempting to release Android tablets this spring.

translate2.jpg

Performance of these binary translated applications will be lower than they would be natively, as you would expect, but to what degree? These results, again gathered by ARM, show a 20-40% performance drop in games like Riptide GP2 and Minecraft while also increasing "jank" - a measure of smoothness and stutter found with variances in frame rates. These are applications that exist in a native mode but were tricked into running through binary conversion as well. The insinuation is that we can now forecast what the performance penalty is for applications that don't have a natively compiled version and are forced to run in translation mode.

translate3.jpg

The result of this is lower battery life as it requires the CPU to draw more power to keep the experience close to nominal. While gaming on battery, which most people do with items like the Galaxy Tab 3 used for testing, a 20-35% decrease in game time will hurt Intel's ability to stand up to the best ARM designs on the market.

Other downsides to this binary translation include longer load times for applications, lower frame rates and longer execution time. Of course, the Galaxy Tab 3 10.1 is based on Intel's Atom Z2560 SoC, a somewhat older Clover Trail+ design. That is the most modern currently available Android platform from Intel as we are still awaiting Bay Trail units. This also explains why ARM did not do any direct performance comparisons to any devices from its partners. All of these results were comparing Intel in its two execution modes: native and translated.

Without a platform based on Bay Trail to look at and test, we of course have to use the results that ARM presented as a placeholder at best. It is possible that Intel's performance is high enough with Silvermont that it makes up for these binary translation headaches for as long as necessary to see x86 more ubiquitous. And in fairness, we have seen many demonstrations from Intel directly that show the advantage of performance and power efficiency going in the other direction - in Intel's favor. This kind of debate requires some more in-person analysis with hardware in our hands soon and with a larger collection of popular applications.

More from our visit with ARM soon!

The Health of Intel's Many Divisions...

Subject: General Tech, Processors, Mobile | April 16, 2014 - 08:40 PM |
Tagged: Intel, silvermont, arm, quarterly earnings, quarterly results

Sean Hollister at The Verge reported on Intel's recent quarterly report. Their chosen headline focuses on the significant losses incurred from the Mobile and Communications Group, the division responsible for tablet SoCs and 3G/4G modems. Its revenue dropped 52%, since last quarter, and its losses increased about 6%. Intel is still making plenty of money, with $12.291 billion USD in profits for 2013, but that is in spite of Mobile and Communications losing $3.148 billion over the same time.

intel-computex-07.jpg

Intel did have some wins, however. The Internet of Things Group is quite profitable, with $123 million USD of income from $482 million of revenue. They also had a better March quarter than the prior year, up a few hundred million in both revenue and profits. Also, Mobile and Communications should have a positive impact on the rest of the company. The Silvermont architecture, for instance, will eventually form the basis for 2015's Xeon Phi processors and co-processors.

It is concerning that Internet of Things has over twice the sales of Mobile but I hesitate to make any judgments. From my position, it is very difficult to see whether or not this trend follows Intel's projections. We simply do not know whether the division, time and time again, fails to meet expectations or whether Intel is just intentionally being very aggressive to position itself better in the future. I would shrug off the latter but, obviously, the former would be a serious concern.

The best thing for us to do is to keep an eye on their upcoming roadmaps and compare them to early projections.

Raspberry Pi Compute Module Will Work With Custom PCBs

Subject: General Tech | April 10, 2014 - 01:55 PM |
Tagged: videocore iv, Raspberry Pi, bcm2835, arm

Although the Raspberry Pi's original purpose was as an educational tool, many enthusiasts have used the (mostly) open source hardware at the heart of home automation, robotics projects, and other embedded systems. In light of this success, the Raspberry Pi Foundation has unveiled the Raspberry Pi Compute Module, a miniaturized version of the Raspberry Pi sans IO ports that fits onto a single SO-DIMM module. The Compute Module houses the BCM2835 SoC, 512MB of RAM, and 4GB of flash memory and can be paired with custom designed PCBs.

The Raspberry Pi Compute Module. Note that the pin out is entirely different from a memory module, so don't try plugging this into your laptop!

The Compute Module will initially be released along with an open source breakout board called the Compute Module IO Board. The IO Board is intended to be an example to get users started and to help them along the path of designing their own customized PCB. The IO Board has a SO-DIMM connector that the Compute Module plugs into. It further offers up two serial camera ports, two serial display ports, two banks of 2x30 GPIO pinouts, a micro USB port for power, one full-size USB port, and one HDMI output. The Raspberry Pi Foundation will be releasing full documentation and schematics for both the Compute Module and IO Board over the next few weeks.

Using the Compute Module and a custom PCB, the embedded system can be smaller and lighter than then traditional Raspberry Pi.

The Raspberry Pi Compute Module and IO Board will be available as a bundle (the "Compute Module Development Kit") from Element14 and RS in June. Shortly after the development kit launch, customers will be able to purchase the compute module itself for $30 each in batches of 100 or slightly more for smaller orders.

More information can be found on the Raspberry Pi blog. Here's hoping the industrial / embedded market successes will help fuel additional educational endeavours and new Raspberry Pis versions in the future.

Tagged: Samsung, exynos 5, chromebook 2, Chromebook, chrome os, arm

Samsung is bringing a new Chromebook to market next month. Coming in 11-inch and 13-inch form factors the new Samsung Chromebook 2 offers updated hardware and more than eight hours of battery life.

The Chromebook 2 will be available in 11.6” and 13.3” models. The smaller variant will come in white or black while the larger SKU is only available in gray. The lids use a soft touch plastic that resembles stitched leather like that found on some Samsung smartphones. The 11.6” is 0.66-inches thick and weighs 2.43 pounds. The 13.3” model is 0.65-inches thick and weighs 3.09 pounds. The 11.6” Chromebook 2 has a 1366x768 display while the 13.3” Chromebook uses a 1920 x 1080 resolution display.

Internally, the Chromebook 2 is powered by an unspecified Exynos 5 Octa SoC at either 1.9GHz (11.6”) or 2.1GHz (13.3”), 4GB of DDR3L memory, and 16GB internal SSD storage. Internal radios include 802.11ac Wi-Fi and Bluetooth 4.0. Samsung rates the battery life at 8 hours for the 11.6” Chromebook and 8.5 hours for the 13.3” Chromebook.

Beyond the wireless tech, I/O includes one USB 3.0 port, one USB 2.0 port, one HDMI, one headphone output, and one micro SD card slot. This port configuration is available on both Chromebook 2 sizes.

Samsung Chromebook 2 13-Inch In Gray.jpg

Samsung is launching its Chromebook 2 in April at $319.99 and $399.99 for the 11.6” and 13.3” respectively. This new Chromebook is coming to a competitive market that is increasingly packed with Bay Trail-powered Windows 8.1 notebooks (and tablets) that are getting cheaper and Android tablets that are getting more features and more powerful thanks to new ARM-based SoCs. I'm interested to see what platform users start gravitating towards, is the cloud-connected Chrome OS good enough when paired with good battery life and a physical keyboard?

Are you looking forward to Samsung's new Chromebook 2?
