GLOBALFOUNDRIES Technical Conference Releases

Subject: General Tech | September 20, 2017 - 09:44 PM |
Tagged: GLOBALFOUNDRIES, FinFET, FD-SOI, 12nm, 14nm, 14nm+, 22FDX, 28FDX, 12FDX, amd, Vega, ryzen

The day after Intel had its Technology and Manufacturing expo in China, GLOBALFOUNDRIES kicks off their own version of the event and has made a significant number of announcements concerning upcoming and next generation process technologies. GF (GLOBALFOUNDRIES) had been the manufacturing arm of AMD until it was spun off as its own entity in 2009. Since then GF has been open to providing fabless semiconductor firms a viable alternative to TSMC and other foundries. Their current 14nm process is licensed from Samsung, as GF had some significant issues getting their own version of that technology into production. GF looks to be moving past their process hiccups in getting to FinFET technologies as well as offering other more unique process nodes that will serve upcoming mobile technologies very well.

The big announcement today was the existence of the 12LP process. This is a "12 nm" process that looks to be based off of their previous 14nm work. It is a highly optimized variant that offers around 15% better density and 10% better performance than current 14/16nm processes from competing firms. Some time back GF announced that it would be skipping the 10nm node and going directly to 7nm, but it seems that market forces have pushed them to further optimize 14nm and offer another step.  Regular process improvement cadences are important to fabless partners as they lay out their roadmaps for future products.
 
12FP is also on track to be Automotive Grade 2 Certified by Q4 2017, which opens it up to a variety of automotive applications. Self-driving cars are the hot topic these days and it appears as though GF will be working with multiple manufacturers including Tesla. The process also has an RF component that can be utilized for those designs.
 
There had been some questions before this about what GF would do between 14nm and their expected 7nm offering. AMD had previously shown a roadmap with the first generation Zen being offered on 14nm and a rather nebulous sounding 14nm+ process. We now know that 12LP is going to be the process that AMD leverages for Zen and Vega refreshes next year. GF is opening up risk production in 1H 2018 for early adopters. This typically means that tuning is still going on with the process, and wafer agreements tend to not hinge on "per good die". Essentially, just as the wording suggest, the monetary risks of production fall more on the partner rather than the foundry. I would expect the Zen/Vega refreshes to start rolling out mid-Summer 2018 if all goes well with 12LP.

RF is getting a lot of attention these days. In the past I had talked quite a bit about FD-SOI and the slow adoption of that technology. In the 5G world that we are heading to, RF is becoming far more important. Currently GF has their 28FDX and 22FDX processes which utilize FD-SOI (Fully Depleted Silicon On Insulator). 22FDX is a dual purpose node that can handle both low-leakage ASICs as well as RF enabled products (think cell-phone modems). GF has also announced a new RF centric process node called 8SW SOI. This is a 300mm wafer based technology at Fab 10 located in East Fishkill, NY. This was once an IBM fab, but was eventually "given" to GF for a variety of reasons. The East Fishkill campus is also a center for testing and advanced process development.
 
22FDX is not limited to ASIC and RF production. GF is announcing that it is offering eMRAM (embedded magnetoresistive non-volatile memory) support. GF claims that ic an retain data through a 260C solder reflow while retaining data for more than 10 years at 125C. These products were developed through a partnership with Everspin Technologies. 1Gb DDR MRAM chips have been sampled and 256Mb DDR MRAM chips are currently available through Everspin. This technology is not limited to standalone chips and can be integrated into SOC designs utilizing eFlash and SRAM interface options.
 
GLOBALFOUNDRIES has had a rocky start since it was spun off from AMD. Due to aggressive financing from multiple sources it has acquired other pure play foundries and garnered loyal partners like AMD who have kept revenue flowing. If GF can execute on these new technologies they will be on a far more even standing with TSMC and attract new customers. GF has the fab space to handle a lot of wafers, but these above mentioned processes could be some of their first truly breakthrough products that differentiates itself from the competition.

Divinity: Original Sin 2 arrives

Tagged: gaming, divinity original sin 2

The original game was the first RPG that offered you a chance to argue with yourself, with a unique method of dialogue between the two main characters you played.  It incorporated the environmental effects of spells in a much more effective way than the majority of RPGs, making it wise to dump water on an opponent before zapping them with a lightning bolt.  The quests were often quite unique and the sequel seems to keep that alive, one reviewer at Rock, Paper, SHOTGUN describes how they "ate the meat from the shark’s mouth" as part of the solution to a quest.  If you are looking for a different type of fantasy RPG that will make you smile, cry and scratch your head, often simultaneously, then check out the review and see if you want to pick up the game that launched today.

Intel Technology and Manufacturing Day in China

Tagged: Intel, China, cannon lake, coffee lake, 10nm, 14nm+, 14nm++, 22FFL, GLOBALFOUNDRIES, Samsung, 22FDX

Today in China Intel is holding their Technology and Manufacturing Day. Unlike previous "IDF" events this appears to be far more centered on the manufacturing aspects of Intel's latest process nodes. During presentations Intel talked about their latest steps down the process ladder to smaller and smaller geometries all the while improving performance and power efficiency.

It really does not seem as though 14nm has been around as long as it has, but the first Intel products based on that node were released in the 2nd half of 2014.  Intel has since done further work on the process. Today the company talked about two other processes as well as products being made on these nodes.
 
The 10nm process has been in development for some time and we will not see products this year. Instead we will see two product cycles based on 14nm+ and 14nm++ parts. Intel did show off a wafer of 10nm Cannon Lake dies. Intel claims that their 10nm process is still around 3 years more advanced than the competition. Other foundry groups have announced and shown off 10nm parts, but overall transistor density and performance does not look to match what Intel has to offer.
 
We have often talked about the marketing names that these nodes have been given, and how often their actual specifications have not really lived up to the reality. Intel is not immune to this, but they are closer to describing these structures than the competition. Even though this gap does exist, competition is improving their products and offering compelling solutions at decent prices so that fabless semi firms can mostly keep up with Intel.

A new and interesting process is being offered by intel in the form of 22FFL. This is an obviously larger process node, but it is highly optimized for low power operation with far better leakage characteristics than the previous 22nm FF process that Intel used all those years ago. This is aimed at the ultra-mobile devices with speeds above 2 GHz. This seems to be a response to other low power lines like the 22FDX product from GLOBALFOUNDRIES. Intel did not mention potential RF implementations which is something of great interest from those also looking at 22FDX.
 
Perhaps the biggest news that was released today is that of Intel Custom Foundry announcing and agreement with ARM to develop and implement those CPUs on the upcoming 10nm process. This can have a potentially huge impact depending on the amount of 10nm line space that Intel is willing to sell to ARM's partners as well as what timelines they are looking at to deliver products. ARM showed off a 10nm test wafer of Cortex-A75 CPUs. The company claims that they were able to design and implement these cores using industry standard design flows (automated place and route, rather than fully custom) and achieving performance in excess of 3 GHz.

Intel continues to move forward and invest a tremendous amount of money in their process technology. They have the ability to continue at this rate far beyond that of other competitors. Typically the company does a lot of the heavy lifting with the tools partners, which then trickles down to the other manufacturers. This has allowed Intel to stay so far ahead of the competition, and with the introduction of 14nm+, 14nm++, and 10nm they will keep much of that lead. Now we must wait and see what kind of clockspeed and power performance we see from these new nodes and how well the competition can react and when.

Texting troubles with 2FA

Subject: General Tech | September 19, 2017 - 02:07 PM |
Tagged: security, sms, 2fa

Two factor authentication is the way to go when dealing with important information online, unfortunately the most common way of enabling 2FA has proven rather vulnerable.  With just your name, surname and phone number an unsavoury type could use a vulnerability on cellular networks to gain access to your accounts.  The example given over at Slashdot is of a Coinbase wallet with 2FA, registered with a Gmail address also protected by 2FA, which the security researchers easily took control of.  Take a look at the article for more details on the SS7 network vulnerabilities this attack exploits as well as better ways of making use of 2FA. 

If you do intend to continue to use SMS as part of your 2FA, at least consider disabling the feature on your phone which allows you to breifly read a text without unlocking your phone.

"The report notes of several ways you can protect yourself from this sort of attack: "On some services, you can revoke the option for SMS two-factor and account recovery entirely, which you should do as soon as you've got a more secure app-based method established. Google, for instance, will let you manage two-factor and account recovery here and here; just set up Authenticator or a recovery code, then go to the SMS option for each and click 'Remove Phone.'"

If the rumours are true, the new 14nm Raven Ridge based AMD Ryzen 5 2500U will offer an impressive jump in performance compared to AMD's current generation of APUs.  The Inquirer's source suggests the new APU will offer a 50% jump in single threaded performance and an impressive 90% advantage on multi-threaded performance.  The multithreaded performance improvement may be the headline but seeing a huge increase in single threaded applications, AMD's recent Achilles Heel, shows some interesting improvements to Zen.  This will also mark the arrival of their first APU with Vega onboard, so you can expect better graphics performance as well.  The benchmark numbers and links are here.

Street View Added to Google Earth VR Desktop

Subject: General Tech | September 17, 2017 - 08:57 PM |
Tagged: google, VR

So this is a bit of a weird one. As our readers are probably well aware, Google Maps offers Street View, which allows you to see 360-degree images from a car as it travels as many roads as it can... since, like, 2007. Also, this year, they are beginning to upgrade the quality of these images with new cars. Now that VR is taking off, it would be kind-of cool to see this data around you. Daydream (and apparently Cardboard) have an app that offers a few locations that you can view... sort-of like you would see in QuickTime in the 90s. Meanwhile, on Oculus, you had Google Earth, which let you see a view that was based on their new 3D Google Maps Satellite view, but it wouldn’t pull in the Street View data.

Now it will. A couple of days ago, Google updated Google Earth VR to allow teleporting into that spherical image. You will see a preview in a sphere atop your left hand. The weird part, though, is that you can’t travel while within street view. As far as I can tell, you need to jump back to the satellite view, move, then drop back down into street view any time you want to go anywhere. This... makes little sense to me, unless they plan on adding that feature but it just didn’t make this release schedule. It seems like they have all of the pieces scattered across existing software, but it's obviously next-to-impossible to tell for sure from the outside. Perhaps the data linked into the web-based Street View is insufficient for some reason?

Rant aside, if you have a compatible headset (which Steam says is an Oculus Rift or an HTC Vive) then it’s worth a free download to check it out.

AMD Ryzen 5 2500U APU With Vega Graphics Spotted in Geekbench Benchmarks

Subject: General Tech | September 16, 2017 - 03:32 AM |
Tagged: Zen, Vega, ryzen 5, ryzen, raven ridge, APU, amd

Back in May AMD made Ryzen Mobile official indicating that the APUs previously known as "Raven Ridge" would be launching in the second half of 2017. As that launch window closes, more details are starting to trickle out including benchmarks scores. The latest appearance of Raven Ridge is in a Geekbench benchmark score results page where a "Ryzen 5 2500U" APU achieves a single core score of 3,561 and a multi-core score of 9,421. These are fairly impressive results on their own, but especially considering that Ryzen Mobile chips are reportedly using up to 50% less power versus last generation Bristol Ridge processors while handily beating them in performance offered.

AMD has previously claimed that its Ryzen Mobile (Raven Ridge) APUs will offer up to 50% more CPU performance and 40% more GPU performance compared to its 7th Generation APUs. The leaked Geekbench scores seem to back up those claims (for the most part) with the Ryzen 5 2500U scoring slightly above 36% better single core performance and 48% better multi-core performance compared to the AMD A12-9800 APU with the latter being due primarily to the addition of SMT to the processor design allowing for twice the number of CPU threads (eight total). The performance improvements are also due to the move from Excavator to a Zen-based design on a smaller more power efficient process node. What is most impressive about this mobile part is that it is that much faster than a 65W quad core (4 core / 4 thread) desktop Bristol Ridge APU clocked at 3.8 GHz base and 4.2 GHz boost while using approximately half the power!

Geekbench Ryzen 5 2500U Vega APU.png

The Geekbench benchmark is only one data point, but is still a positive sign. One thing it does not reveal is clockspeed as while it lists 2.0 GHz that number is likely only the base and not the maximum boost frequency. Further, details on the Vega-based GPU are still unknown although the Infinity Fabric should help tremendously in reducing the bottleneck and keeping the on die GPU fed with data while gaming especially when paired with fast dual channel memory or HBM (I just hope that Ryzen Mobile is not held back like previous generation mobile APUs were with laptop manufacturers pairing them with single channel memory setups). We also do not know officially the number of stream processors that will be included in any of the Vega GPUs used in Ryzen Mobile with past rumors going up to 1024 SPs (mobile parts will likely be capped at 512 or 768 at the extreme). AMD claims that Ryzen Mobile will offer up to 40% more GPU performance, which to me suggests that we will possibly see higher GPU core counts but for the most part performance improvements are going to come from architecture improvements.

I am really interested to see how Raven Ridge plays out and hope that it is one step closer to finally realizing that HSA future AMD has been promsing me for years!

Corsair's K68 keyboard is immune to spit-takes

Subject: General Tech | September 14, 2017 - 03:17 PM |
Tagged: input, corsair, K68, cherry mx red, water resistant

The K68 is not washable nor waterproof but thanks to a membrane under the keys, the Cherry MX Red switches and PCBs are protected from inadvertent spills or splashes.  Physically it resembles other Corsair keyboards such as the K70, though with a plastic body and only a red glow available as opposed to being fully RGB.  The Tech Report tested it out and did not find the membrane to interfere with key presses and it did indeed survive being doused with a full glass of water.

"Corsair's K68 keyboard blends the company's usual recipe of Cherry MX switches and discrete media controls with an unusual new feature: a water-resistant membrane under the keys that could provide insurance against splashes and spills during heavy gaming. We gave this board a splash to see how it works."

Tagged: microsoft, windows 10, security

The new Creators Update for Windows 10 just received a noteworthy upgrade.  Installed applications will now need your agreement to collect and transmit metadata such as your location and other information.  Many of the concerns raised by Windows 10 users focused on the current configuration which defaults to apps being allowed permission to track and send information; it can be turned off by a user but only after the fact.  Now applications will be installed with telemetry disabled by default unless a user agrees to the collection of information during the installation.  There are cases in which it is beneficial to send your usage information, especially Windows error reports, but that was no excuse to enable that ability across the board.  The Inquirer also mentions that the Enterprise version will offer greater control and limit the OS to local notifications of serious issues or updates.

"Starting with the new Creators Update, you will be required to explicitly give permission for each piece of access and there's even a full privacy statement to wallow through (or more likely ignore, make tea) during install."

Toshiba Negotiating With Bain Capital For Sale of Its NAND Manufacturing Arm

Subject: General Tech, Storage | September 14, 2017 - 10:32 AM |
Tagged: western digital, toshiba, nand, flash memory, bain capital

Toshiba remains in a financial crisis in the aftermath of massive losses in its Westinghouse US Nuclear power division and has been attempting to sell off its still very much profitable NAND flash manufacturing business to compensate and right the company to avoid being delisted from the Tokyo Stock Exchange. Unfortunately for Toshiba it has now missed three target dates for selling off the business. Not for lack of suitors, but primarily because of legal issues resulting from anti-trust concerns as well as legal battles brought by Western Digital  – who Toshiba is in a joint venture with for flash manufacturing in Japan – to attempt to prevent the sale.

XG5_front_angled_2_small.png

Jumping to the present, Toshiba has decided to proceed with the negotiations with an investment group led by Bain Capital despite disappointment (and more legal objections) from Western Digital who tried to block similar negotiations back in June. On Wednesday, it was revealed that Toshiba had signed a “memorandum of understanding” and is engaging in private talks to negotiate the sale with an investment group led by Bain Capital and including SK Hynix (who is allegedly only providing financing at this point and not going after a stake in the business to try to avoid further delaying the sale from increased anti-trust red tape), Apple, Dell, Seagate, and two Japanese government controlled entities known as Innovation Network Corp and Development Bank of Japan (again, Bain Capital is offering them the chance to invest post any WD concessions and legal battles in the business to improve chances of the sale going through). As the preferred (by Toshiba) buyer, the Bain Capital-lead group deal is reportedly worth nearly 2.4 trillion Yen ($22 billion USD) including $1.8 billion earmarked for infrastructure. The company expects come to an agreement in late September and is hoping that it will be able to finalize the sale by March so that it can avoid reporting negative net worth and risking being de-listed from the Tokyo Stock Exchange and being cut off from a huge swath of public investors and capital.

Due to the negotiations being private, details are not readily available yet. It is not clear whether Toshiba will be able to pull it off or what the implications will be for the market if it does. (With Toshiba being the world’s second largest flash memory supplier, whoever ends up acquiring the company is going to have a lot of influence on the market and flash technology R&D.) It certainly seems Toshiba’s battle to right itself is going to continue into next year and Western Digital is not going to make it easy. The US-based WD stated:

“We are disappointed that Toshiba would take this action. Our goal has been — and remains — to reach a mutually beneficial outcome that satisfies the needs of Toshiba and its stakeholders.”

A California court has reportedly ordered Toshiba to give Western Digital two weeks’ notice of any deal with the consortium and its two previous arbitration requests through ICC are still pending resolution. Barrons reports that Toshiba may convince WDC to allow the sale if it gives its joint venture partner enough concessions such as an assured long term NAND supply contract and agreed participation in joint Fab projects that would protect SanDisk's contractual rights. Other interested parties for the sale include Foxconn and Western Digital itself. Perhaps SoftBank or the $100 Billion Vision Fund will come in and scoop it up as well.

[Opinions follow heh] I am interested to see how it all will eventually shake out. It remains less than ideal to see Toshiba must sell it off and have the market possibly lose a big flash memory player as the market share power gets more consolidated if it does get picked up by an existing memory manufacturer (see: hard drives, flash memory seems to be going through the same consolidation of companies from lots of little players into fewer bigger ones). I am not certain on the deal specifics as far as ownership and control of TMC and any cash only vs equity splits but with Japanese investors as part of all three bidding / competing consortiums it seems at least part of the business (if only money from it if not voting power) will remain rooted in Japan even if not under the Toshiba brand.

Colorful Reveals Custom Eight Slot Motherboard For Cryptocurrency Miners

Subject: General Tech, Motherboards | September 14, 2017 - 02:13 AM |
Tagged: password cracking, mining, gpgpu, cryptocurrency, colorful, ai

Colorful recently unveiled an interesting bare-bones motherboard focused on cryptocurrency miners and other GPU heavy workloads with its main feature being eight double spaced PCI-E 3.0 x16 slots. The non-standard form factor Colorful C.B250A-BTC PLUS V20 motherboard measures 485mm x 195mm (approx. 19.1 x 7.7 inches) and offers a no-frills setup that is ready for miners to attach to open racks. The motherboard is based on Intel’s LGA 1151 socket and B250 chipset.

Colorful C_B250A-BTC PLUS Mining 8 slot motherboard.jpg

The majority of the board is taken up by eight PCI-E 3.0 x16 slots where the top slot is wired directly to the CPU and is electrically x16 while the rest are wired to the B250 chipset and are x1 slots. There are 16(!) PCI-E power connectors (eight 6-pin and eight 8-pin) for providing power to the GPU and two 4-pin ATX power connectors for powering the CPU and single SO-DIMM slot through what looks to be six power phases. Notably, there is no 24-pin power connector on this board to make it easier to use multiple power supplies and share motherboards between power supplies (though it’s not clear how Colorful plans to control turning all these power supplies on/off at the same time). Beyond the PCI-E slots there is not much to this motherboard. Internal I/O includes the 1151 socket for Skylake and Kaby Lake CPUs, a single DDR4 SO-DIMM slot, one SATA port, one M.2 slot, and six fan headers. Around back are two USB ports, one HDMI video output, and a single gigabit ethernet port.

The board is a no-frills design that should be quite appealing for miners but also as an easy way to jump into GPGPU projects (AI research, rendering, machine learning, password cracking, etc.). The 2-slot spacing allows air cooled (hopefully blower style) cards to be installed without needing to find and test quality PCI-E riser cables. There is no word on pricing yet, and while it should be on the cheaper side based on the features and hardware it’s packing as it’s a custom design aimed at mining it may actually come out at a hefty premium for the convenience it offers them. On the bright side, it might have decent resale value to factor into the ROI calculations for the other non-mining applications I mentioned (a mean password cracking rig!). A neat board in any case, and as I mentioned previously it is interesting to see the new designs and configurations the mining craze has enticed manufacturers into exploring.

Intel Releases Dawson Canyon NUCs With 15W Kaby Lake CPUs

Subject: General Tech, Systems | September 13, 2017 - 07:29 PM |
Tagged: SFF, nuc, kaby lake, Intel

Following last year’s Baby Canyon NUC kits, Intel is launching its Dawson Canyon NUCs powered by 15W Kaby Lake processors. Despite Dawson Canyon sounding more dramatic than Baby Canyon (which sounds more like a creek), the new NUCs are lower powered and ditch Iris Graphics and USB 3.1 Type C.

Specifically, Intel is launching six new models that will come in three flavors: barebones board, slim case kit, and a taller kit with room for a 2.5” drive. Each type of NUC kit will come with either a Core i3 or Core i5 processor. Dawson Canyon further supports Intel RST (Rapid Storage Technology) and Optane memory.

Intel Dawson Canyon.jpg

Processor options include the Core i3 7100U (2.4 GHz) and Core i5 7300U (2.6 GHz base, 3.5 GHz boost) which are both dual core processors with HyperThreading, 3 MB cache, Intel HD Graphics 620 GPUs, and 15W TDPs.

Internal I/O includes two DDR4 SO-DIMM slots, two M.2 slots (one full length (80mm) and one 30mm slot for Wi-Fi adapters such as the included Intel 8265 with is included in the kits with cases but not the bare board kits.), one SATA port, and headers for serial, USB 3.0, and USB 2.0 ports.

External I/O consists of four USB 3.0 ports, one Gigabit Ethernet port, and two HDMI outputs (one protected UHD).

Dawson Canyon NUCs will be available towards the end of the year (Q4’17) with pricing yet to be released. For the fanless, ahem, fans Fanless Tech reports that Simply NUC will be offering NUCs with custom fanless cases. These are likely to be cheaper than Baby Canyon and be popular with businesses wanting monitor mounted thin clients or low power workstations for office users that just need to run productivity applications.

Blender Foundation Releases Blender 2.79

The latest version of Blender, 2.79, makes a few significant changes, especially for users with AMD GPUs. Their main rendering engine, Cycles, has now reached feature-parity on OpenCL and CUDA. While those with NVIDIA GPUs will keep using the latter compute API, users of recent AMD GPUs can now (on Windows and Linux -- macOS requires a driver update) harness their graphics cards for higher performance.

10 samples is actually very low. I'm usually in the 100-1000 range.

For the rest of us, there are four improvements that I would consider major. First, Cycles now has a denoise filter, which reduces speckles and thus should let you get away with fewer samples. Second, Filmic Color Management is now included by default, which can represent a much wider dynamic range. This was available as a user mod for a while, but you needed to manually install it. Third is a shadow catcher object for Cycles, which lets you render off translucent shadows onto dummy objects and composite them later (in Photoshop, After Effects, or Blender’s video editor).

Fourth, and most interesting to me, is their new PBR shader. I’ve done PBR materials in Cycles before, and it’s a bit of a pain to set up. If I don’t copy/paste from an existing material, it takes about 15-20 minutes of my time to wire together diffuse nodes, glossy nodes, Fresnel nodes, and so forth such that I can attach metal, bump, and so forth to it. Now? Just drag in one node and hook up the correct textures and colors, like the ones that are generated in Substance or Quixxel.

As always, Blender is free, so have fun.

The Fallout: New Vegas prequel mod may soon arrive as Fallout: New California

This mod has been eight years in the making but we may soon see it released for us all to enjoy.  The New Vegas mod will put you into the wilds of the NCR after being rather abruptly ejected from your home in Vault 18.  This will be a nice experience for those who found Fallout 4 to have strayed a bit far from the games roots, especially in the dialogue.  Head over to Rock, Paper, SHOTGUN for a video showing off the mod and giving you a look into how your adventure will start.

"Vault 18 is at the heart of the California Wasteland high in the San Bernardino Mountains, and its legendary Wasteland Scouts have managed to keep its secrets safe for decades despite the wars raging beyond the great door. In their old age, their adventures have created a new generation to take their place… if their rebellious adopted kids survive the threat brewing within their own ranks."

So, about that D‑Link DIR 850L wireless AC1200 you might be using ...

If you have a D-Link DIR 850L wireless router or know anyone that does, you should unplug it without delay.  The Register posted a link to the recently released findings of security researcher Pierre Kim, who originally contacted D-Link in February about the flaws only to see a single patch released since then.  The vulnerabilities are rather severe, ranging from a lack of verification for firmware images, through stored default private keys to an actual buit in backdoor.  The router is not compatible with DD-WRT so you cannot resolve the issue through that method; it should be treated as a brick until D-Link resolves these issues in an update.

Fool me once, shame on me ... Chrome gives Symantec the cold shoulder

Subject: General Tech | September 12, 2017 - 02:29 PM |
Tagged: chrome, symantec, security

The original issue dates back two years ago, when a serious security issue was discovered effecting all Norton and Symantec products which allowed an attacker to easily infect your Windows kernel without any user interaction.  Following that revelation were a round of firings at Symantec which were intended to reassure customers and security experts which were somewhat successful, until earlier this year.  In January it was discovered that Symantec provided digital certificates to verify the authenticity of several questionable sites, including ones never authorized by ICANN.  This has been enough for Google; Chrome will no longer trust older Symantec certs in version 66 and will not trust any as of version 70.  The Inquirer provides a full timeline here.

"The decision to remove Symantec certificates came as a result of the discovery of a dodgy certificate in 2015, leading to a fuller investigation that brought forward more issues with security at the beginning of this year."

Samsung Announces 11nm LPP and 7nm LPP Processes

Subject: General Tech | September 11, 2017 - 05:27 PM |

Process technology is extremely complex today, and getting more and more complex by the minute.  The billions of dollars invested in each process node essentially insures that it will have to be used for years to come to get back that investment.  It not only needs to get back that investment, but provide more funds to start R&D on the next series of nodes that will come down the line.  It has only been a couple of years since the introduction of multiple 14nm processes from Intel and Samsung, as well as the 16nm node from TMSC.  We are already moving towards an introduction of 10nm parts from these manufacturers in bulk starting next year.  So have these manufacturers gotten their money worth out of their current processes?
 
Samsung-Foundry-Forum2017_main_1.jpg
 
Kinam Kim, President of Samsung Electronics’ Semiconductor Business, discloses the latest process advances from his division.
 
Part of that answer somes in the form of Samsung's latest product.  Samsung is announcing the availability of a new 11nm FinFET process that looks to be a pretty extensive optimization of the company's 14nm FF.  The new process promises 15% better performance and 10% chip area reduction at the same power consumption as the older 14nm FF.  The idea here is to further improve upon their 14nm process all the while retaining the economics of it.  This process exists separately from the latest 10nm LPP which can be considered a full jump from the previous 14nm.  11nm LPP will be primarily aimed at midrange and high end products, but will not reach the full scaling and performance of the 10nm LPP product.
 
This "little steps" philosophy has been around for ages, as AMD utilized it for most of their existence when they owned their own Fabs.  Other companies have done the same by including small improvements over the lifetime of the process so that the final product is signficantly better in terms of yield, transistor switching speed, and thermal dissipation.  Samsung looks to be doing this with their 11nm process by providing all those little steps of improvement from 14nm.
 
The second part of the announcement is that Samsung has announced their 7nm process using EUV.  Samsung had previously announced their 8nm process, but it still relies upon multi-patterning immersion litho.  Samsung has been testing their 250 watt EUV source with fairly good results.  The company is quoted as to processing over 200,000 wafers since 2014 and has achieved an 80% yeild on 256 Mb SRAM.  This is somewhat impressive, but still not ready for primetime.  SRAM features highly consistent structures and is typically one of the first complex chips tested on a new process.
 
Samsung is offering orders now of its 11nm line and it will be very interesting to see who jumps on board.  I would not expect AMD to transfer their designs to 11nm, as a tremendous amount of reworking and validating are required. Instead we will see AMD going for the 10nm node with their Zen 2 based products while continuing to produce Ryzen, Vega, and Polaris at 14nm. Those that will be taking advantage of 11nm will probably be groups pushing out smaller products, especially for the midrange and high end cell phone SOCs.
 
10nm LPP is expected in early 2018, 8nm LPP in 2019, and finally Samsung hopes for 7nm to be available in 2020.
