Tagged: iot, security, amazon, Intel
The Register brings up the issue of IoT security once again today, this time looking at the logistics of patching and updating a fleet of IoT devices. Amazon is focusing on dumb devices with a smart core, the physical device having the sensors required and a connection to the net to send all data to be processed in large database which would be much easier to maintain but does offer other security issues. Intel on the other hand unsurprisingly prefers end devices with some smarts, such as their Curie and Edison modules, with a smarter gateway device sitting between those end devices and the same sort of large server based computing as Amazon.
Intel's implementation may be more effective in certain enviroments than Amazons, El Reg uses the example of an oil rig, but would be more expensive to purchase and maintain. Take a look at the article for a deeper look, or just imagine the horrors of pushing out a critical patch to 1000's of devices in an unknown state when you go live.
"Internet of Things (IoT) hype focuses on the riches that will rain from the sky once humanity connects the planet, but mostly ignores what it will take to build and operate fleets of things.
And the operational side of things could be hell."

According to Olivier over at FanlessTech, Intel will be launching two new small form factor NUC PCs later this year. The new NUCs are code named Baby Canyon and Arches Canyon and will be powered by Intel’s Kaby Lake-U and Apollo Lake processors respectively. Baby Canyon will occupy the high end while Arches Canyon is aimed at low power and budget markets.
Left: Intel NUC Roadmap. Middle: Intel Baby Canyon NUC. Right: Intel Arches Canyon NUC.
First up is the “Baby Canyon” NUC which will come in five SKUs. Featuring aluminum enclosures, the Baby Canyon NUCs measure 115 x 111 x 51mm for models with a SATA drive (models without SATA drive support are shorter at 35mm tall). The PCs will be powered by Intel’s Kaby Lake-U processors up to a 28W quad core i7 chip with Iris graphics. There will also be 15W Core i5 and i3 models. Kaby Lake is the 14nm successor to Skylake and features native support for USB 3.1, HDCP 2.2, and HEVC. Further, Kaby Lake chips will reportedly utilize an improved graphics architecture. While Kaby Lake chips in general will be available with TDPs up to 95W, the models used in Baby Canyon NUCs top out at 28W and are the Kaby Lake-U mobile variants.
Baby Canyon NUCs will pair the Kaby Lake-U CPUs with dual channel DDR4 SODIMMs (up to 32GB), a M.2 SSD, and SATA hard drive (on some models). Networking is handled by a soldered down Intel’s Wireless AC + BT 4.2 WiFI NIC and an Intel Gigabit Ethernet NIC.
Connectivity includes two USB 3.0 ports (one charging), a Micro SDXC card slot, 3.5mm audio jack, and an IR port on the front. Rear IO is made up of two more USB 3.0 ports, HDMI 2.0 video output, Gigabit Ethernet port, and a USB 3.1 (Gen1 5Gbps) Type-C port with support for DisplayPort 1.2 (DisplayPort Alt Mode). Finally, users can get access two USB 2.0 ports via an internal header.
Arches Canyon will be the new budget NUC option in 2017 and will be powered by Intel’s Apollo Lake SoC. Arches Canyon is the same 115 x 111 x 51mm size as the higher end Baby Canyon NUC, but the reference Intel chassis will be primarily made of plastic to reduce cost. Moving to the lower end platform, users will lose out on the USB 3.1 Type-C port, M.2 slot, and DDR4 support. Instead, the Arches Canyon NUCs will use dual channel DDR3L (up to 8GB) and come in two models: one with 32GB of built-in eMMC storage and one without. Both models will support adding in a SATA SSD or hard drive though.
External IO includes four USB 3.0 ports (two front, two rear, one charging), two 3.5mm audio jacks (the rear port supports TOSLINK), one Micro SDXC slot, one HDMI 2.0 video output, a VGA video out, and a Gigabit Ethernet port.
Internally, Arches Canyon is powered by Celeron branded Apollo Lake SoCs which are the successor to Braswell and feature Goldmont CPU cores paired with Gen 9 HD Graphics. Intel has not announced the specific chip yet, but the chip used in these budget NUCs will allegedly be a quad core model with a 10W TDP. Apollo Lake in general is said to offer up to 30% more CPU and GPU performance along with 15% better battery life over current Braswell designs. The battery savings are not really relevant in a NUC, but the performance improvements should certainly help!
One interesting contradiction in these Intel slides is that the Baby Canyon slide mentions Thunderbolt 3 (40Gbps) and USB 3.1 Gen 2 (10Gbps) support for the USB Type-C connector but in the connectivity section limits the USB 3.1 Type-C port to Gen 1 (5Gbps) and no mention of Thunderbolt support at all. I guess we will just have to wait and see if TB3 will end up making the cut!
The new NUCs look promising in that they should replace the older models at their current price points (for the most part) while offering better performance which will be especially important on the low end Arches Canyon SKUs! Being NUCs, users will be able to buy them as barebones kits or as systems pre-loaded with Windows 10.
If the chart is accurate, both Baby Canyon and Arches Canyon will be launched towards the end of the year with availability sometime in early to mid 2017. There is no word on exact pricing, naturally.

The ThinkPwn vulnerability which has been in the news lately, which allows attackers to disable Secure Boot and bypass Virtual Secure Mode on Win10 Enterprise as well as disabling flash write protection turns out not to be yet another questionable Lenovo feature. Instead the problem lies with the motherboards UEFI, specifically the Intel System Management Mode implemented on Gigabyte motherboards. So far the issue has been located on Z68-UD3H, Z77X-UD5H, Z87MX-D3H, and Z97-D3H but it is possible that the vulnerability exists on far more motherboards, perhaps even beyond Gigabyte as the flaw is in the Intel code. The Register also postulates this could effect HP Pavilion machines as they use these boards as well.
"Gigabyte has been swept into turmoil surrounding low-level security vulnerabilities that allows attackers to kill flash protection, secure boot, and tamper with firmware on PCs by Lenovo and other vendors."

A new competitor has entered the arena!
When we first saw the announcement of the MateBook in Spain back in March, pricing was immediately impressive. The base model of the tablet starts at just $699; $200 less than the lowest-priced Surface Pro 4, with features and performance that pretty closely match one another.
The MateBook only ships with Core m processors, a necessity of the incredibly thin and fanless design that Huawei is using. That obviously will put the MateBook behind other tablets and notebooks that use the Core i3/i5/i7 processors, but with a power consumption advantage along the way. Honestly, the performance differences between the Core m3 and m5 and m7 parts is pretty small – all share the same 4.5 watt TDP and all have fairly low base clock speeds and high boost clocks. The Core m5-6Y54 that rests in our test sample has a base clock of 1.1 GHz and a maximum Turbo Boost clock of 2.7 GHz. The top end Core m7-6Y75 has a base of 1.2 GHz and Boost of 3.1 GHz. The secret of course is that these processors run at Turbo clocks very infrequently; only during touch interactions and when applications demand performance.
If you work-load regularly requires you to do intensive transcoding, video editing or even high-resolution photo manipulation, the Core m parts are going to be slower than the Core i-series options available in other solutions. If you just occasionally need to use an application like Photoshop, the MateBook has no problems doing so.

|Operating System||Windows 10 Home / Pro|
Update: The Huawei Matebook is now available on Amazon.com!
At the base level, both the Surface Pro 4 and the MateBook have identical specs, but the Huawei unit is priced $200 lower. After that, things get more complicated as the Surface Pro 4 moves to Core i5 and Core i7 processors while the MateBook sticks with m5 and m7 parts. Storage capacities and memory size scale though. The lowest entry point for the MateBook to get 256GB of storage and 8GB of memory is $999 and comes with a Core m5 processor; a comparable Surface Pro 4 uses a Core i5 CPU instead but will run you $1199. If you want to move from 256GB to 512GB of storage, Microsoft wants $400 more for your SP4, while Huawei’s price only goes up $200.

Tagged: dx12, 6700k, Intel, i7-6950X
[H]ard|OCP has been conducting tests using a variety of CPUs to see how well DX12 distributes load between cores as compared to DX11. Their final article which covers the 6700K and 6950X was done a little differently and so cannot be directly compared to the previously tested CPUs. That does not lower the value of the testing, scaling is still very obvious and the new tests were designed to highlight more common usage scenarios for gamers. Read on to see how well, or how poorly, Ashes of the Singularity scales when using DX12.
"This is our fourth and last installment of looking at the new DX12 API and how it works with a game such as Ashes of the Singularity. We have looked at how DX12 is better at distributing workloads across multiple CPU cores than DX11 in AotS when not GPU bound. This time we compare the latest Intel processors in GPU bound workloads."

Tagged: Intel, kaby lake, iGPU, h.265, hevc, vp8, vp9, codec, codecs
Fudzilla isn't really talking about their sources, so it's difficult to gauge how confident we should be, but they claim to have information about the video codecs supported by Kaby Lake's iGPU. This update is supposed to include hardware support for HDR video, the Rec.2020 color gamut, and HDCP 2.2, because, if videos are pirated prior to their release date, the solution is clearly to punish your paying customers with restrictive, compatibility-breaking technology. Time-traveling pirates are the worst.
According to their report, Kaby Lake-S will support VP8, VP9, HEVC 8b, and HEVC 10b, both encode and decode. However, they then go on to say that 10-bit VP9 and 10-bit HEVC 10b does not include hardware encoding. I'm not too knowledgeable about video codecs, but I don't know of any benefits to encoding 8-bit HEVC Main 10. Perhaps someone in our comments can clarify.

Tagged: Intel, amd, antitrust
This is a saga for the ages and a snit worthy of any 2 year old child. 11 years ago AMD filed suit against Intel citing questionable business tactics Intel had been using worldwide. Intel was offering discounted parts to retailers if they would use Intel chips exclusively. For instance, if a company like Dell offered an AMD alternative then Intel would raise the price of every Intel component sold to Dell across the board. This is, of course, illegal.
The court cases were settled in 2009, in the US Intel agreed to pay AMD $1.25 billion USD to settle all outstanding court cases in the US and several overseas. In the UK there was a seperate court case which also went against Intel, the courts there requiring Intel to pay AMD €1.06bn, the largest ever fine in the UK. Since then Intel has been fighting tooth and nail to find a way not to pay the fine and while they have not succeeded in their legal battle they have succeeded in not paying AMD one single cent. Their initial appeal was dismissed in 2014 but that has not stopped Intel from delaying the payment and as of today that fine still remains unpaid. The Inquirer posted today about their latest challenge to the ruling, Intel's legal team claims that it somehow unfair to be punished for unfair business practices.
Six years on and over 1 billion dollars that should be AMDs is still under a couch cushion in Intel's offices somewhere.
"CHIPMAKER Intel ain't giving up and continues to fight the €1.06bn (around £815m) antitrust fine levied on the firm six years ago."

Tagged: nuc, Intel, NUC6i5SYK, Skylake
The new NUC6i5SYK may look like the previous generations but the innards represent a huge step forward. At the base is a Skylake Core i5-6260U which brings with it support for DDR4 and more importantly NVMe SSDs. Connectivity includes Ethernet, 802.11AC Dual Band WiFi, miniDP 1.2 and proper HDMI CEC 1.4b output. The barebones kit will run $380USD, not bad for this type of design. Missing Remote put the new NUC through its paces; check out the results here.
"Updated with an Intel Core i5-6260U with Intel Iris Graphics 540, support for NVMe SSD, and DDR4, the system has the opportunity to fix the shortcomings in the previous generation (cough, CSH). The sleek looks and features will not be as much of a bargain as the plug-in-and-go Intel Pentium based NUC5PGYH. Intel is asking $380/£335 for the barebones kit, but with quite a bit more performance, better networking, and features on tap, it could well be worth the extra dosh."

For those unaware, XPoint (spoken 'cross-point') is a new type of storage technology that is persistent like NAND Flash but with speeds closer to that of RAM. Intel's brand name for devices implementing XPoint are called Optane.
Starting at the bottom of the slide, we see a new 'System Acceleration' segment with a 'Stony Beach PCIe/NVMe m.2 System Accelerator'. This is likely a new take on Larson Creek, which was a 20GB SLC SSD launched in 2011. This small yet very fast SLC flash was tied into the storage subsystem via Intel's Rapid Storage Technology and acted as a caching tier for HDDs, which comprised most of the storage market at that time. Since Optane excels at random access, even a PCIe 3.0 x2 part could outmaneuver the fastest available NAND, meaning these new System Accelerators could act as a caching tier for Flash-based SSDs or even HDDs. These accelerators can also be good for boosting the performance of mobile products, potentially enabling the use of cheaper / lower performing Flash / HDD for bulk storage.
Skipping past the mainstream parts for now, enthusiasts can expect to see Brighton Beach and Mansion Beach, which are Optane SSDs linked via PCIe 3x2 or x4, respectively. Not just accelerators, these products should have considerably more storage capacity, which may bring costs fairly high unless either XPoint production is very efficient or if there is also NAND Flash present on those parts for bulk storage (think XPoint cache for NAND Flash all in one product).
We're not sure if or how the recent delays to Kaby Lake will impact the other blocks on the above slide, but we do know that many of the other blocks present are on-track. The SSD 540s and 5400s were in fact announced in Q2, and are Intel's first shipping products using IMFT 3D NAND. Parts not yet seen announced are the Pro 6000p and 600p, which are long overdue m.2 SSDs that may compete against Samsung's 950 Pro. Do note that those are marked as TLC products (purple), though I suspect they may actually be a hybrid TLC+SLC cache solution.
Going further out on the timeline we naturally see refreshes to all of the Optane parts, but we also see the first mention of second-generation IMFT 3DNAND. As I hinted at in an article back in February, second-gen 3D NAND will very likely *double* the per-die capacity to 512Gbit (64GB) for MLC and 768Gbit (96GB) for TLC. While die counts will be cut in half for a given total SSD capacity, speed reductions will be partially mitigated by this flash having at least four planes per die (most previous flash was double-plane). A plane is an effective partitioning of flash within the die, with each section having its own buffer. Each plane can perform erase/program/read operations independently, and for operations where the Flash is more limiting than the interface (writes), doubling the number of planes also doubles the throughput. In short, doubling planes roughly negates the speed drop caused by halving the die count on an SSD (until you reach the point where controller-to-NAND channels become the bottleneck, of course).
IMFT XPoint Die shot I caught at the Intel / Micron launch event.
Well, that's all I have for now. I'm excited to see that XPoint is making its way into consumer products (and Storage Accelerators) within the next year's time. I certainly look forward to testing these products, and I hope to show them running faster than they did back at that IDF demo...
