AMD Details Carrizo Further

Some months back AMD introduced us to their “Carrizo” product.  Details were slim, but we learned that this would be another 28 nm part that has improved power efficiency over its predecessor.  It would be based on the new “Excavator” core that will be the final implementation of the Bulldozer architecture.  The graphics will be based on the latest iteration of the GCN architecture as well.  Carrizo would be a true SOC in that it integrates the southbridge controller.  The final piece of information that we received was that it would be interchangeable with the Carrizo-L SOC, which is a extremely low power APU based on the Puma+ cores.

A few months later we were invited by AMD to their CES meeting rooms to see early Carrizo samples in action.  These products were running a variety of applications very smoothly, but we were not informed of speeds and actual power draw.  All that we knew is that Carrizo was working and able to run pretty significant workloads like high quality 4K video playback.  Details were yet again very scarce other than the expected timeline of release, the TDP ratings of these future parts, and how it was going to be a significant jump in energy efficiency over the previous Kaveri based APUs.

AMD is presenting more information on Carrizo at the ISSCC 2015 conference.  This information dives a little deeper into how AMD has made the APU smaller, more power efficient, and faster overall than the previous 15 watt to 35 watt APUs based on Kaveri.  AMD claims that they have a product that will increase power efficiency in a way not ever seen before for the company.  This is particularly important considering that Carrizo is still a 28 nm product.

Project Lead: Joris-Jan van ‘t Land

Thanks to Ian Comings, guest writer from the PC Perspective Forums who conducted the interview of Bohemia Interactive's Joris-Jan van ‘t Land. If you are interested in learning more about ArmA 3 and hanging out with some PC gamers to play it, check out the PC Perspective Gaming Forum!

I recently got the chance to send some questions to Bohemia Interactive, a computer game development company based out of Prague, Czech Republic, and a member of IDEA Games. Bohemia Interactive was founded in 1999 by CEO Marek Španěl, and it is best known for PC gaming gems like Operation Flashpoint: Cold War Crisis, The ArmA series, Take On Helicopters, and DayZ. The questions are answered by ArmA 3's Project Lead: Joris-Jan van ‘t Land.

PC Perspective: How long have you been at Bohemia Interactive?

VAN ‘T LAND: All in all, about 14 years now.

PC Perspective: What inspired you to become a Project Lead at Bohemia Interactive?

VAN ‘T LAND: During high school, it was pretty clear to me that I wanted to work in game development, and just before graduation, a friend and I saw a first preview for Operation Flashpoint: Cold War Crisis in a magazine. It immediately looked amazing to us; we were drawn to the freedom and diversity it promised and the military theme. After helping run a fan website (Operation Flashpoint Network) for a while, I started to assist with part-time external design work on the game (scripting and scenario editing). From that point, I basically grew naturally into this role at Bohemia Interactive.

arma3_screenshot_02.jpg

PC Perspective: What part of working at Bohemia Interactive do you find most satisfying? What do you find most challenging?

VAN ‘T LAND: The amount of freedom and autonomy is very satisfying. If you can demonstrate skills in some area, you're welcome to come up with random ideas and roll with them. Some of those ideas can result in official releases, such as Arma 3 Zeus. Another rewarding aspect is the near real-time connection to those people who are playing the game. Our daily Dev-Branch release means the work I do on Monday is live on Tuesday. Our own ambitions, on the other hand, can sometimes result in some challenges. We want to do a lot and incorporate every aspect of combat in Arma, but we're still a relatively small team. This can mean we bite off more than we can deliver at an acceptable level of quality.

PC Perspective: What are some of the problems that have plagued your team, and how have they been overcome?

VAN ‘T LAND: One key problem for us was that we had no real experience with developing a game in more than one physical location. For Arma 3, our team was split over two main offices, which caused quite a few headaches in terms of communication and data synchronization. We've since had more key team members travel between the offices more frequently and improved our various virtual communication methods. A lot of work has been done to try to ensure that both offices have the latest version of the game at any given time. That is not always easy when your bandwidth is limited and games are getting bigger and bigger.

NVIDIA Faces Class Action Lawsuit for the GeForce GTX 970

Subject: Graphics Cards | February 23, 2015 - 04:12 PM |
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.

nvidia-970-architecture.jpg

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.

Intel Plans 7nm in 2018

Subject: Processors | February 26, 2015 - 10:27 PM |
Tagged: Intel, 14nm, 10nm, 7nm

In the PC industry, our CPUs are beginning to appear at 14nm while graphics processors have been at 28nm for a few years. Smaller features allow for more complicated circuits in the same area, which allows for less power, less heat, and more products to be created from a single wafer (assuming you can keep defects to a minimum). Intel expects to release 10nm in late 2016 (possibly slipping into early 2017) and has just announced plans for 7nm in 2018.

Intel-logo.png

According to Ars Technica, this 7nm process is expected to move beyond silicon FinFETs. At room temperature, a 7nm structure of Silicon is a lattice that is approximately 14 atoms wide. Intel was quiet with the details, but Ars expects that “III-V transistors” will be the next stage -- semiconductors made from alloys of Group III and Group V metals. One example of a III-V semiconductor is Indium Gallium Arsenic. Indium and Gallium are Group III while Arsenic is Group V. Apart from using a new material for transistors, it is speculated that Intel might change the way that they package chips into a 2.5D or 3D configuration (maybe even depending on the use case).

Imagination Launches PowerVR GT7900, "Super-GPU" Targeting Consoles

Subject: Graphics Cards, Mobile | February 26, 2015 - 02:15 PM |
Tagged: super-gpu, PowerVR, Imagination Technologies, gt7900

As a preview to announcements and releases being made at both Mobile World Congress (MWC) and the Game Developers Summit (GDC) next week, Imagination Technologies took the wraps off of a new graphics product they are calling a "super-GPU". The PowerVR GT7900 is the new flagship GPU as a part of its Series7XT family that is targeting a growing category called "affordable game consoles." Think about the Android-powered set-top devices like the Ouya or maybe Amazon's Kindle TV.

gt7900-1.png

PowerVR breaks up its GPU designs into unified shading clusters (USCs) and the GT7900 has 16 of them for a total of 512 ALU cores. Imagination has previously posted a great overview of its USC architecture design and how you can compare its designs to other GPUs on the market. Imagination wants to claim that the GT7900 will offer "PC-class gaming experiences" though that is as ambiguous as the idea of a work load of a "console-level game." But with rated peak performance levels hitting over 800 GFLOPS in FP32 and 1.6 TFLOPS in FP16 (half-precision) this GPU does have significant theoretical capability.

  PowerVR GT7900 Tegra X1
Vendor Imagination Technologies NVIDIA
FP32 ALUs 512 256
FP32 GFLOPS 800 512
FP16 GFLOPS 1600 1024
GPU Clock 800 MHz 1000 MHz
Process Tech 16nm FinFET+ 20nm TSMC

Imagination also believes that PowerVR offers a larger portion of its peak performance for a longer period of time than the competition thanks to the tile-based deferred rendering (TBDR) approach that has been "refined over the years to deliver unmatched efficiency."

gt7900-2.png

The FP16 performance number listed above is useful as an extreme power savings option where the half-precision compute operates in a much more efficient manner. A fair concern is how many applications, GPGPU or gaming, actually utilize the FP16 data type but having support for it in the GT7900 allows developers to target it.

Other key features of the GT7900 include support for OpenGL ES 3.1 + AEP (Android Extension Pack), hardware tessellation and ASTC LDR and HDR texture compression standards. The GPU also can run in a multi-domain virtualization mode that would allow multiple operating systems to run in parallel on a single platform.

gt7900-3.png

Imagination believes that this generation of PowerVR will "usher a new era of console-like gaming experiences" and will showcase a new demo at GDC called Dwarf Hall.

I'll be at GDC next week and have already setup a meeting with Imagination to talk about the GT7900 so I can have some hands on experiences to report back with soon. I am continually curious about the market for these types of high-end "mobile" GPUs with the limited market that the Android console market currently addresses. Imagination does claim that the GT7900 is beating products with performance levels as high as the GeForce GT 730M discrete GPU - no small feat.

Windows 10 Technical Preview Build 10022 Spotted

Subject: General Tech | February 26, 2015 - 07:00 AM |
Tagged: windows 10, windows, microsoft

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.

Intel Revamps Atom Branding, Next Generation Atoms Will Come in x3, x5, and x7 Tiers

Subject: General Tech | February 26, 2015 - 02:02 AM |
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?

Intel Pushes Broadwell to the Next Unit of Computing

Intel continues to invest a significant amount of money into this small form factor product dubbed the Next Unit of Computing, or NUC. When it was initially released in December of 2012, the NUC was built as an evolutionary step of the desktop PC, part of a move for Intel to find new and unique form factors that its processors can exist in. With a 4" x 4" motherboard design the NUC is certainly a differentiating design and several of Intel's partners have adopted it for products of their: Gigabyte's BRIX line being the most relevant. 

But Intel's development team continues to push the NUC platform forward and today we are evaluating the most recent iteration. The Intel NUC5i5RYK is based on the latest 14nm Broadwell processor and offers improved CPU performance, a higher speed GPU and lower power consumption. All of this is packed into a smaller package than any previous NUC on the market and the result is both impressive and totally expected.

A Walk Around the NUC

To most poeple the latest Intel NUC will look very similar to the previous models based on Ivy Bridge and Haswell. You'd be right of course - the fundamental design is unchanged. But Intel continues to push forward in small ways, nipping and tucking away. But the NUC is still just a box. An incredibly small one with a lot of hardware crammed into it, but a box none the less.

IMG_1619.jpg

While I can appreciate the details including the black and silver colors and rounded edges, I think that Intel needs to find a way to add some more excitement into the NUC product line going forward. Admittedly, it is hard to inovate in that directions with a focus on size and compression.

Seemingly Out of Spec AC Cables Could Be a Fire Hazard

Subject: General Tech | February 23, 2015 - 03:31 PM |
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.

vantec-my-far.jpg

My cable

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.

vantec-my-close.jpg

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).

VantecPowerCableOfDeath-Conductors.jpg

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.

Roll over Superfish, PrivDog is just as bad and comes from Comodo

Subject: General Tech | February 25, 2015 - 12:36 PM |
Tagged: fud, Comodo, SSL, security, PrivDog, idiots

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 3.0.96.0 and 3.0.97.0 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.

picarddoublefacepalm.jpg

"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."

So Long Adware, and Thanks for All the Fish!

Subject: Graphics Cards | March 1, 2015 - 07:30 AM |
Tagged: superfish, Lenovo, bloatware, adware

Obviously, this does not forget the controversy that Lenovo got themselves into, but it is certainly the correct response (if they act how they imply). Adware and bloatware is common to find on consumer PCs, which makes the slowest of devices even more sluggish as demos and sometimes straight-up advertisements claim their share of your resources. This does not even begin to discuss the security issues that some of these hitchhikers drag in. Again, I refer you to the aforementioned controversy.

lenovo-do.png

In response, albeit a delayed one, Lenovo has announced that, by the launch of Windows 10, they will only pre-install the OS and “related software”. Lenovo classifies this related software as drivers, security software, Lenovo applications, and applications for “unique hardware” (ex: software for an embedded 3D camera).

It looks to be a great step, but I need to call out “security software”. Windows 10 should ship with Microsoft's security applications in many regions, which really questions why a laptop provider would include an alternative. If the problem is that people expect McAfee or Symantec, then advertise pre-loaded Microsoft anti-malware and keep it clean. Otherwise, it feels like keeping a single finger in the adware take-a-penny dish.

At least it is not as bad as trying to install McAfee every time you update Flash Player. I consider Adobe's tactic the greater of two evils on that one. I mean, unless Adobe just thinks that Flash Player is so insecure that you would be crazy to install it without a metaphorical guard watching over your shoulder.

And then of course we reach the divide between “saying” and “doing”. We will need to see Lenovo's actual Windows 10 devices to find out if they kept their word, and followed its implications to a tee.

Samsung has announced the new Galaxy S phones at MWC, and the new S6 and S6 Edge should be in line with what you were expecting if you’ve followed recent rumors.

As expected we no longer see a Qualcomm SoC powering the new phones, and as the rumors had indicated Samsung opted instead for their own Exynos 7 Octa mobile AP. The Exynos SoC’s have previously been in international versions of Samsung’s mobile devices, but they have apparently ramped up production to meet the demands of the US market as well. There is an interesting twist here, however.

14nmOcta.jpg

The Exynos 7420 powering both the Galaxy S6 and S6 Edge is an 8-core SoC with ARM’s big.LITTLE design, combining four ARM Cortex-A57 cores and four Cortex-A53 cores. Having announced 14nm FinFET mobile AP production earlier in February the possibility of the S6 launching with this new part was interesting, as the current process tech is 20nm HKMG for the Exynos 7. However a switch to this new process so soon before the official announcement seemed unlikely as large-scale 14nm FinFET production was just unveiled on February 16. Regardless, AnandTech is reporting that the new part will indeed be produced using this new 14nm process technology, and this gives Samsung an industry-first for a mobile SoC with the launch of the S6/S6 Edge.

GSM Arena has specs of the Galaxy S6 posted, and here’s a brief overview:

  • Display: 5.1” Super AMOLED, QHD resolution (1440 x 2560, ~577 ppi), Gorilla Glass 4
  • OS: Android OS, v5.0 (Lollipop) - TouchWiz UI
  • Chipset: Exynos 7420
  • CPU: Quad-core 1.5 GHz Cortex-A53 & Quad-core 2.1 GHz Cortex-A57
  • GPU: Mali-T760
  • Storage/RAM: 32/64/128 GB, 3 GB RAM
  • Camera: (Primary) 16 MP, 3456 x 4608, optical image stabilization, autofocus, LED flash
  • Battery: 2550 mAh (non-removable)

The new phones both feature attractive styling with metal and glass construction and Gorilla Glass 4 sandwiching the frame, giving each phone a glass back.

Intel Sheds Its Remaining Stake In Imagination Technologies

Subject: General Tech | February 25, 2015 - 08:56 PM |
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.

PowerVR Rogue Series6XT GPU.png

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!)

Quiet, Efficient Gaming

The last few weeks have been dominated by talk about the memory controller of the Maxwell based GTX 970.  There are some very strong opinions about that particular issue, and certainly NVIDIA was remiss on actually informing consumers about how it handles the memory functionality of that particular product.  While that debate rages, we have somewhat lost track of other products in the Maxwell range.  The GTX 960 was released during this particular firestorm and, while it also shared the outstanding power/performance qualities of the Maxwell architecture, it is considered a little overpriced when compared to other cards in its price class in terms of performance.

It is easy to forget that the original Maxwell based product to hit shelves was the GTX 750 series of cards.  They were released a year ago to some very interesting reviews.  The board is one of the first mainstream cards in recent memory to have a power draw that is under 75 watts, but can still play games with good quality settings at 1080P resolutions.  Ryan covered this very well and it turned out to be a perfect gaming card for many pre-built systems that do not have extra power connectors (or a power supply that can support 125+ watt graphics cards).  These are relatively inexpensive cards and very easy to install, producing a big jump in performance as compared to the integrated graphics components of modern CPUs and APUs.

The GTX 750 and GTX 750 Ti have proven to be popular cards due to their overall price, performance, and extremely low power consumption.  They also tend to produce a relatively low amount of heat, due to solid cooling combined with that low power consumption.  The Maxwell architecture has also introduced some new features, but the major changes are to the overall design of the architecture as compared to Kepler.  Instead of 192 cores per SMK, there are now 128 cores per SMM.  NVIDIA has done a lot of work to improve performance per core as well as lower power in a fairly dramatic way.  An interesting side effect is that the CPU hit with Maxwell is a couple of percentage points higher than Kepler.  NVIDIA does lean a bit more on the CPU to improve overall GPU power, but most of this performance hit is covered up by some really good realtime compiler work in the driver.

Asus has taken the GTX 750 Ti and applied their STRIX design and branding to it.  While there are certainly faster GPUs on the market, there are none that exhibit the power characteristics of the GTX 750 Ti.  The combination of this GPU and the STRIX design should result in an extremely efficient, cool, and silent card.

Don't forget the 1TB Crucial BX100 costs less than $400

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.

List of Upcoming USB 3.1 Devices Expected by Mid-2015

Subject: Storage | February 24, 2015 - 11:11 AM |
Tagged: usb 3.1, usb, msi, asus

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?

Your aggregate battery consumption isn't Li-On about your location

Subject: General Tech | February 24, 2015 - 12:56 PM |
Tagged: fud, security, smartphone

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.
