Week in Review:
News item of interest:
Question: Alex from Sydney
Just a quick question regarding DirectX 12. I’m planning to buy a new graphics card soon but I want a DirectX 12 card for all the fancy new features so I’m considering either the GTX 970 or 980, the question I have is are these real DirectX 12 cards? Since DirectX 12 development is still ongoing how can these cards be fully DirectX 12 complaint?

Tagged: Gemalto, SIM, encryption, fud, security
In just under a week SIM card maker Gemalto claims to have done a complete security audit of their systems in 85 different countries and reports that "its office networks were compromised, the servers holding the SIM card encryption keys weren't." This is a record worthy of Guinness as most security audits take months or years to complete and the findings tend to discuss probabilities, not absolute certainties. As you might expect The Register and security experts everywhere are doubtful of the claims from a company that did not even know if was compromised less than a week ago that the UK based GCHQ and USA based NSA are unable to compromise your SIM cards encryption when they have the keys in hand. It has not been a good week for anyone who thinks about security.
"Six days ago Gemalto, the world's largest SIM card manufacturer, was told that back in 2010 it had been ransacked by NSA and GCHQ hackers. Today the company gave itself the all-clear: no encryption keys, used to secure phone calls from eavesdroppers, were stolen, it claims."

WZor, a group in Russia that somehow acquires many Windows leaks, has just published screenshots of Windows 10 Build 10022 and Windows Server Build 9926. As far as we can tell, not much has changed. We see neither an upgraded Cortana nor a look at the Spartan browser. The build is not labeled “Microsoft Confidential” though, which makes people believe that it is (or was) intended for public release -- maybe as early as this week.

Honestly, I do not see anything different from the provided screenshots apart from the incremented version number. It is possible that this build addresses back-end issues, leaving the major new features for BUILD in late April. Leaked notes (also by WZor) for build 10014, called an “Early Partner Drop”, suggest that version was designed for hardware and software vendors. Perhaps the upcoming preview build is designed to give a platform for third-parties to develop updates ahead of Microsoft releasing the next (or second-next) big build?
Either way, it seems like we will get it very soon.

Tagged: SoFIA, moorefield, Intel, Cherry Trail, branding, atom
Intel is updating its Atom processor branding to better communicate the expected performance and experience customers can expect from their Intel powered mobile device. In fact, the new branding specifies three tiers. Atom processors will soon come in Atom x3, x5, and x7 flavors. This branding scheme is similar to the Core processor branding using the i3, i5, and i7 labels.
The Atom x3, x5, and x7 chips are low power, efficient processors for battery powered devices and sit below the Core M series which in turn are below the Core i3, i5, and i7 processors. The following infographic shows off the new branding though Intel does not reveal any specific details about these new Atom chips (we will hopefully know more after Mobile World Congress). Of course, Atom x3 chips will reside in smartphones with x5 and x7 chips powering tablets and budget convertibles. The x7 brand represents the flagship processors of the Atom line.
The new branding will begin with the next generation of Atom chips which should include Cherry Trail, the 14nm successor to Bay Trail featuring four x86 Airmont cores and Gen 8 Intel graphics. Cherry Trail (Cherryview SoC) will be used in all manner of mobile devices from entry level 8"+ tablets to larger notebooks and convertibles. It appears that Intel will use Moorefield (a quad core 14nm refresh of Merrifield) through 2015 for smartphones though road maps seem to indicate that Intel's budget SoFIA SoC will also launch this year. SoFIA and Moorefield processors should fall under the Atom x3 brand with the higher powered and higher clocked Cherry Trail chips will use the Atom x5 and x7 monikers.
What are your thoughts on Intel's new Atom x3/x5/x7 brands?

Tagged: PowerVR, Intel, Imagination Technologies, igp, finance
Update: Currency exchange rates have been corrected. I'm sorry for any confusion!
Intel Foundation is selling off its remaining stake in UK-based Imagination Technologies (IMG.LN). According to JP Morgan, Intel is selling off 13.4 million shares (4.9% of Imagination Technologies) for 245 GBp each. Once all shares are sold, Intel will gross just north of $50.57 Million USD.
Imagination Technologies' PowerVR Rogue Series 6XT GPU is used in Apple's A8-series chips.
Intel first invested in Imagination Technologies back in October of 2006 in a deal to gain access to the company’s PowerVR graphics IP portfolio. Since then, Intel has been slowly moving away from PowerVR graphics in favor of it’s own internal HD graphics GPUs. (Further, Intel sold off 10% of its IMG.LN stake in June of last year.) Even Intel’s low cost Atom line of SoCs has mostly moved to Intel GPUs with the exception of the mobile Merrifield and Moorefield” smartphone/tablet SoCs.
The expansion of Intel’s own graphics IP combined with Imagination Technologies acquisition of MIPS are reportedly the “inevitable” reasons for the sale. According to The Guardian, industry analysts have speculated that, as it stands, Intel is a minor customer of Imagination Technologies at less than 5% for graphics (a licensing agreement signed this year doesn’t rule out PowerVR graphics permanently despite the sale). Imagination Technologies still has a decent presence in the mobile (ARM-based) space with customers including Apple, MediaTek, Rockchip, Freescale, and Texas Instruments.
Currently, the company’s stock price is sitting at 258.75 GBp (~$3.99 USD) which seems to indicate that the Intel sell off news was “inevitable” and was already priced in or simply does not have investors that concerned.
What do you think about the sale? Where does this leave Intel as far as graphics goes? Will we see Intel HD Graphics scale down to smartphones or will the company go with a PowerVR competitor? Would Intel really work with ARM’s Mali, Qualcomm’s Adreno, or Samsung’s rumored custom GPU cores? On that note, an Intel powered smartphone with NVIDIA Tegra graphics would be amazing (hint, hint Intel!)

Dell's Venue 8 7000 tablet sports an 8.4" 2560x1600 OLED display and is powered by the Moorefield based Atom Z3580 SOC, 2GB LPDDR3-1600 with 16GB internal of internal storage with up to a 512GB Micro SD card supported. Even more impressive is that The Tech Report had no issues installing apps or moving files to the SD card with ES File Explorer, unlike many Android devices that need certain programs to reside on the internal storage media. Like Ryan, they had a lot of fun with the RealSense Camera and are looking forward to the upgrade to Lollipop support. Check out The Tech Report's opinion of this impressive Android tablet right here.
"Dell's Venue 8 7000 is the thinnest tablet around, and that's not even the most exciting thing about it. This premium Android slate packs a Moorefield-based Atom processor with quad x86 cores, a RealSense camera that embeds 3D depth data into still images, and a staggeringly beautiful OLED display that steals the show. Read on for our take on a truly compelling tablet."

That's right, for those of you who pre-ordered Homeworld Remastered and for anyone that pops by Steam to purchase it, your productivity is in for a serious hit as you try to guide your fleet to a new homeworld and then defend it. For those lucky and old enough to have played through it originally you will find the look vastly improved and from what Rock, Paper, SHOTGUN and other reviewers have found you will also love the improved interface. For those who have not had the pleasure of playing through these two games before, the $33 investment is more than worth it, especially with improved multiplayer coming in the near future. Check out the videos and overview of the poster child for revamped legacy games here.
You will have to take a break this Saturday though, as the Fragging Frogs Virtual LAN party #9 kicks off at 10AM ET and will end when the last frog drops. You can check out the official thread in the forums right here to get all the information you need to participate. AMD and other mystery sponsors will be giving away prizes to those who log into and participate in the TeamSpeak channels; not to mention it is the best way to chat in game and in the general lobby. You can also check out the list of games that will be played as well as links to the mods and patches you will need, please download and install them before Saturday to maximize your playing time. See you there!
"In terms of strategy games which ‘need’ remastering, Homeworld was probably somewhere at the bottom of the list. But in terms of strategy games which really, truly benefit from remastering – well, this is a chart-topper."

Tagged: SSL, security, PrivDog, idiots, fud, Comodo
This has been a bad week for the secure socket layer and the news just keeps getting worse. Comodo provides around one out of every three SSL certs currently in use as they have, until now, had a stirling reputation and were a trusted provider. It turns out that this reputation may not be deserved seeing as how their Internet Security 2014 product ships with an application called Adtrustmedia PrivDog, which is enabled by default. Not only does this app install a custom root CA certificate which intercepts connections to websites to be able to insert customized ads like SuperFish does it can also turn invalid HTTPS certificates into valid ones. That means that an attacker can use PrivDog to spoof your banks SSL cert, redirect you to a fake page and grab your credentials, while all the time your browser reports a valid and secure connection to the site.
The only good news from The Register's article is that this specific vulnerability is only present in PrivDog versions 188.8.131.52 and 184.108.40.206 and so has limited distribution. The fact that this indicates the entire SSL certificate model is broken and even those who create the certs to assure your security feel that inserting a man in the middle attack into their software does not contravene their entire reason for existing is incredibly depressing.
Update: The Register's article was originally based on research from Hanno Bock who referred to PrivDog as being distributed by Comodo. Comodo does not distribute the standalone desktop version of PrivDog only the browser extension application which was never vulnerable to the TLS interception.
"The US Department of Homeland Security's cyber-cops have slapped down PrivDog, an SSL tampering tool backed by, er, SSL certificate flogger Comodo.
Comodo, a global SSL authority, boasts a third of the HTTPS cert market, and is already in hot water for shipping PrivDog."

While it is utterly inconceivable that Josh might have missed something in his look at Carrizo, that hasn't stopped certain Canadians from talking about Gila County, Arizona. AMD's upcoming processor launch is a little more interesting than just another Phenom II launch, especially for those worried about power consumption. With Adaptive Voltage and Frequency Scaling the new Excavator based chips will run very well at the sub-15W per core pair range which is perfect for POS, airplane entertainment and even in casinos. The GPU portion speaks to those usage scenarios though you can't expect an R9 295 at that wattage. Check out Hardware Canucks' coverage right here.

Vertical mice sometimes help those with issues with their cubital or carpal tunnels by relieving pressure due to repetitive arm and wrist movement. They have been around for a while but do not often get reviewed which is why it might be worth checking out eTeknix today. The Adesso E10 is wireless which is relatively uncommon un this type of mouse as is the DPI switch. In addition it has 4 buttons and a mouse wheel so it could still serve as a gaming mouse, at least for right handed gamers who prefer this style of mouse. Check it out if your mousing fingers get numb while you are sitting at your computer.

Tracking your smartphones location via aggregate battery usage is not the most efficient or accurate method but it can be done and Samsung (and others) have not provided a switch which makes that particular data private. Researchers have shown that by tracking the battery drain of the 3G cellular radio on the battery one can determine distance from the cellular base station the phone is connected to and a coarse location based on interference environmental factors such as buildings which partially block the signal. It is only a very coarse locator but does give better information than just the base station the phone is connected to and as we are creatures of habit it allows tracking normal patterns of movement. This is nowhere near as accurate as GPS tracking and does require a bit of work to pull off but as battery usage and levels are sent by the phone in the clear with no method of preventing that it should cause some privacy concerns for users. You can read the research paper (in PDF) by following the link from The Inquirer.
"SCIENTISTS have warned of a new smartphone risk after discovering that battery power can be used to track a person's movements."

Followers of PC Perspective have likely seen a pair of stories previewing the upcoming performance and features of USB 3.1. First we got our hands on the MSI X99A Gaming 9 ACK motherboard and were able to run through our very first hands-on testing with USB 3.1 hardware. The motherboard had built-in USB 3.1 support and a device that was configured with a RAID-0 of Intel SSD 730 Series drives.
We followed that up with a look at the ASUS USB 3.1 implementation that included a PCIe add-on card and a dual-drive mSATA device also in RAID-0. This configuration was interesting because we can theoretically install this $40 product into any system with a free PCI Express slot.
Performance was astounding for incredibly early implementations, reaching as high as 835 MB/s!
In that last article I theorized that it would be some time before we got our hands on retail USB 3.1 hardware but it appears I wasn't giving the industry enough credit. ASUS passed us a list of incoming devices along with release schedules. There are 27 devices scheduled to be released before the end of April and ~35 by the middle of the year.
It's a daunting table to look at, so be prepared!
The product categories are mostly dominated by the likes of the a USB 3.1 to 2.5-in adapter; that would be useful but you aren't going to top out the performance of the USB 3.1 with a single 2.5-in SATA device. Iomaster has one listed as a "USB 3.1 to MSATA & M2 SSD enclosure" which could be more interesting - does it accept PCI Express M.2 SSDs?
Minerva Innovation has a couple of interesting options, all listed with pairs of mSATA or M.2 ports, two with Type-C connections. What we don't know based on this data is if it supports PCIe M.2 SSDs or SATA only and if it supports RAID-0.
A couple more list dual SATA ports which might indicate that we are going to see multiple hard drives / SSDs over a single USB 3.1 connection but without RAID support. That could be another way to utilize the bandwidth of USB 3.1 in a similar way to how we planned to use Thunderbolt daisy chaining.
We don't have pricing yet, but I don't think USB 3.1 accessories will be significantly more expensive than what USB 3.0 devices sell for. So, does this list of accessories make you more excited to upgrade your system for USB 3.1?

It has been about a week since Al posted his review of the 256GB and 512GB models of the Crucial BX100 and what better way to remind you than with a review of the 1TB model, currently a mere $380 on Amazon (or only $374 on BHPhoto.com!). Hardware Canucks cracked open the 1TB budget priced consumer level SSD for your enjoyment right here, as well as running it through a gamut of tests. As expected their results are in line with the 512GB model as they both use a 4 channel controller, which does mean they are slower than some competitors drives. On the other hand the BX100 also has a significantly lower price making the 1TB model much more accessible for users. Check out their post here.

Tagged: nvidia, geforce, GTX 970
So apparently NVIDIA and a single AIB partner, Gigabyte, are facing a class action lawsuit because of the GeForce GTX 970 4GB controversy. I am not sure why they singled out Gigabyte, but I guess that is the way things go in the legal world. Unlucky for them, and seemingly lucky for the rest.
For those who are unaware, the controversy is based on NVIDIA claiming that the GeForce GTX 970 has 4GB of RAM, 64 ROPs, and 2048 KB of L2 Cache. In actuality, it has 56 ROPs and 1792KB of L2 Cache. The main talking point is that the RAM is segmented into two partitions, one that is 3.5GB and another that is 0.5GB. All 4GB are present on the card though, and accessible (unlike the disable L2 Cache and ROPs). Then again, I cannot see an instance in that class action lawsuit's exhibits which claim an incorrect number of ROPs or amount of L2 Cache.
Again, the benchmarks that you saw when the GeForce GTX 970 launched are still valid. Since the issue came up, Ryan has also tried various configurations of games in single- and multi-GPU systems to find conditions that would make the issue appear.

Tagged: Vantec, c13
I say “seemingly out of spec” because I am not an electrician, and this requires more understanding of wire classifications than I possess. Regardless, we found a story a little while ago about devices that ship with power cables that are labeled for voltages and amperages that are significantly lower than what they are capable of carrying.
The minimum requirement for cables with a C13 connector is American 18 gauge (AWG), and they must be able to carry 10 amps. I own the device from the blog posting, like many others at PC Perspective. Again, the device itself (minus the cord that plugs it into the wall) is perfectly fine. The allegation is that the power cord (that goes between the wall and the transformer power brick) cannot carry its full, labeled wattage. The head claims that it can carry 250V at 10A, which is 2500W.
My cable, close up.
We cut open the insides of the cable to see what gauge wire was used, and we were able to remove the insulation with an 18 gauge wire stripper. This is where my lack of applied electrical skills fail me. The power cable feels as flimsy as a quarter-inch audio cable, but I am not qualified to measure the actual internal wires' thickness. It might meet the minimum (18 AWG) requirements, or it might just be thick insulation. I wouldn't trust it, especially not at hundreds or thousands of watts. The blog post author apparently tested their own cable under load, and they claim that it started to melt at 2.6A 123V (320W).
The blog author's wire vs a standard cable's wire. It's hard to tell how thin the Vantec one is, because the standard cable was twisted.

Now, to power a single hard drive and USB controller, you are not going to be drawing those hundreds or thousands of watts from the wall. The main concern is if you swap cables around with other devices. For instance, if that cable would be attached to a high-end gaming desktop, then it could easily see wattages in that range that are sustained for most of a play session, or even higher.
So I guess the takeaway from this is do not trust every power cables that you receive. Make sure your high-power devices are using the cable that came with them, or one from a vendor that you trust. Just because it says it can handle any given load, does not mean that it can.

Ryan just polished off his review of the next generation of Intel NUC, the Broadwell powered NUC5i5RYK in both video and written form but perhaps you still have some questions. If so, or if you are wise enough to prefer a second opinion then you should make time to visit The Tech Report who also received a unit for review. They covered the performance of several indie games, which ran quite well as well as CS:GO which could handle 1600x900 at medium settings. Their conclusion matched Ryan's, not only is this a great HTPC and light gaming machine but for most office purposes this is a perfect solution to present to your users.
"Thanks to the Broadwell-U silicon inside, Intel's new NUC promises better performance and power efficiency than the previous generation. There are other improvements under the hood, too, including the addition of an M.2 storage slot and a built-in Wi-Fi controller."

Firefox can remove any threat that Superfish presents with a simple step and 24 hours; indeed they could prevent any similar issue using a questionable or downright poisonous SSL Certificate simply by blacklisting them. They specifically quote the ability of OneCRL to block even obfuscated certs before the Network Security Services level if the certs are properly recorded on the blacklist in this Register article. This would lead to a much more secure web, requiring attackers to invest significantly more effort when attempting to create fake or dangerous SSL certs. There is a flip side to this, for there are those who may attempt to have valid certs added to the Blacklist and so there must be a way of policing the list and a way to remove certs which should not be on the list due to being placed there in error or because of a change in the software associated with that certificate. It is also likely that there will be court cases attempting to have the blacklist removed if it does come into being as Superfish is not the only business out there whose business model requires phishing or at least a way around proper SSL certification and best practices which will no longer be viable if we are allowed to block their mutant SSL certs.
"Firefox-maker Mozilla may neuter the likes of Superfish by blacklisting dangerous root certificates revealed less than a week ago to be used in Lenovo laptops."

They also claim that Intel and AMD have DirectX 12 drivers available through Windows Update as well. After enabling iGPU graphics on my i7-4790K, the Intel HD 4600 received a driver update, which also reports as WDDM 2.0 in DXDIAG. I do not have a compatible AMD GPU to test against (just a couple of old Windows 7 laptops) but the source is probably right and some AMD GPUs will be updated to DX12 too.
So it turns out that if your motherboard dies during a Windows Update reboot, then you are going to be spending several hours reinstalling software and patches, but that is not important. What is interesting is the installed version number for NVIDIA's GeForce Drivers when Windows Update was finished with its patching: 349.65. These are not available on NVIDIA's website, and the Driver Model reports WDDM 2.0.
It looks like Microsoft pushed out NVIDIA's DirectX 12 drivers through Windows Update. Update 1 Pt. 1: The "Runtime" reporting 11.0 is confusing though, perhaps this is just DX11 with WDDM 2.0?
I am hearing online that these drivers support the GeForce 600 series and later GPUs, and that there are later, non-public drivers available (such as 349.72 whose release notes were leaked online). NVIDIA has already announced that DirectX 12 will be supported on GeForce 400-series and later graphics cards, so Fermi drivers will be coming at some point. For now, it's apparently Kepler-and-later, though.
So with OS support and, now, released graphics drivers, all that we are waiting on is software and an SDK (plus any NDAs that may still be in effect). With Game Developers Conference (GDC 2015) coming up in a little over a week, I expect that we will get each of these very soon.
Update 1 Pt. 2: I should note that the release notes for 349.72 specifically mention DirectX 12. As mentioned above, is possible that 349.65 contains just WDDM 2.0 and not DX12, but it contains at least WDDM 2.0.

One of the perennial firms that measures GPU market share, Jon Peddie Research, has come out with a report on Q4 of 2014 this weekend and the results are eye opening. According to the data, NVIDIA and AMD each took dramatic swings from Q4 of 2013 to Q4 of 2014.

Here is the JPR commentary to start us out:
JPR's AIB Report tracks computer add-in graphics boards, which carry discrete graphics chips. AIBs used in desktop PCs, workstations, servers, and other devices such as scientific instruments. They are sold directly to customers as aftermarket products, or are factory installed. In all cases, AIBs represent the higher end of the graphics industry using discrete chips and private high-speed memory, as compared to the integrated GPUs in CPUs that share slower system memory.
The news was encouraging and seasonally understandable, quarter-to-quarter, the market decreased -0.68% (compared to the desktop PC market, which decreased 3.53%).
On a year-to-year basis, we found that total AIB shipments during the quarter fell -17.52% , which is more than desktop PCs, which fell -0.72%.
However, in spite of the overall decline, somewhat due to tablets and embedded graphics, the PC gaming momentum continues to build and is the bright spot in the AIB market.
NVIDIA's Maxwell GPU
The overall PC desktop market increased quarter-to-quarter including double-attach-the adding of a second (or third) AIB to a system with integrated processor graphics-and to a lesser extent, dual AIBs in performance desktop machines using either AMD's Crossfire or Nvidia's SLI technology.
The attach rate of AIBs to desktop PCs has declined from a high of 63% in Q1 2008 to 36% this quarter.
The year to year change that JPR is reporting is substantial and shows a 20+ point change in market share in favor of NVIDIA over AMD. According to this data, AMD's market share has now dropped from 35% at the end of 2013 to just 24% at the end of 2014. Meanwhile, NVIDIA continues to truck forward, going from 64.9% at the end of 2013 to 76% at the end of 2014.
The Radeon R9 285 release didn't have the impact AMD had hoped
Clearly the release of NVIDIA's Maxwell GPUs, the GeForce GTX 750 Ti, GTX 970 and GTX 980 have impacted the market even more than we initially expected. In recent weeks the GTX 970 has been getting a lot of negative press with the memory issue and I will be curious to see what effect this has on sales in the near future. But the 12 month swing that you see in the table above is the likely cause for the sudden departure of John Byrne, Collette LaForce and Raj Naik.
AMD has good products, even better pricing and a team of PR and marketing folks that are talented and aggressive. So how can the company recover from this? Products, people; new products. Will the rumors circling around the Radeon R9 390X develop into such a product?
Hopefully 2015 will provide it.
