SEC Filing Reveals NVIDIA Now Using Samsung for Some Manufacturing

Want to liven up your weekend? Forget college basketball, we all know that few things are more exciting than SEC filings - and oh boy do we have a great read for you! (OK, this one is actually interesting!)

Ah, legal documents...

NVIDIA has disclosed in their latest 10-K filing that none other than Samsung is manufacturing some of the company’s chips. TSMC has been the source of GPUs for both AMD and NVIDIA for some time, but this filing (the full document is available from the SEC website) has a very interesting mention of the suppliers of their silicon under the “Manufacturing” section:

"We utilize industry-leading suppliers, such as Taiwan Semiconductor Manufacturing Company Limited and Samsung Electronics Co. Ltd, to produce our semiconductor wafers."

Back in December NVIDIA commented on its lawsuit against Samsung for alleged IP theft, which only makes this partnership seem more unlikely. However even Apple (which has their own famous legal history with Samsung, of course) has relied on Samsung for some of the production of their A-series SoCs, including the current crop of A8 chips.  Business is business, and Samsung Foundry has been a reliable source of silicon for multiple manufacturers - particularly during times when TSMC has struggled to meet demand at smaller process nodes.

Samsung's Current Semiconductor Offering

It is unclear at this point whether the wafers produced by Samsung Semiconductor are for NVIDIA’s mobile parts exclusively, or if any of the desktop GPUs were produced there rather than at TSMC. The partnership could also be attributed simply to scale, just as Apple has augmented A8 SoC supply with their rival’s fab while primarily relying on TSMC. It will be interesting to see just how pervasive the chips produced by Samsung are within the NVIDIA lineup, and what future products might be manufactured with their newest 14nm FinFET process technology.

Cougar Launches QBX Mini ITX Case

Subject: Cases and Cooling | March 20, 2015 - 06:47 PM |
Tagged: water cooling, mini ITX, Cougar, air cooling

Cougar recently launched the QBX mini ITX case. The small form factor chassis is aimed squarely at gamers and enthusiasts looking for a high performance PC in a tiny box. 

The QBX is a completely black angular case measuring 7” x 10.2” x 14.5” packed with filtered vents. Front I/O is fairly standard including two USB 3.0 and two audio jacks. The case supports both air and water cooling while holding a ton of hardware. Specifically, the QBX is built to host Mini ITX motherboards, standard size (140mm) ATX power supplies, dedicated graphics cards (350mm), and CPU coolers up to 105mm tall. As far as storage, the QBX can hold a single 3.5” hard drive and four 2.5” solid state drives as well as a single vertically mounted slim optical drive.

The case comes pre-installed with a single 90mm rear fan, and users can install up to six additional fans on the front, top, and side panels. The front and bottom vents have removable dust filters. A 120mm or 240mm radiator can be installed on the left side panel, but at most you can install one 120mm fan to cool the radiator.

Cougar has engineered the case such that the power supply draws in cool air from the right side panel and exhausts it out of the top of the case to prevent adding extra heat to the system (it will be difficult enough to cool high end components in such a small case). Further, removing the left side panel reveals a hinged bracket that holds a fan (or the water cooling radiator) as well as the 3.5” drive bay and two 2.5” bays. Note that with a 240mm radiator installed, you will only be able to access a single 2.5” bay. This is a neat design but installing the CPU block of a closed loop water cooler is going to be a challenge depending on the length of the tubing.

There is some space behind the motherboard try to hide cables but you will likely need to do some custom cabling to not have it ultimately look like a rats nest considering how small this case is and how little area you have to work with, especially if you do end up installing all seven fans and five disk drives!

The Cougar QBX has an MSRP of $60 and will be available soon. More information can be found on this product page. Hopefully we can get one in for review to see how it stacks up to the Ncase M1 and Lian Li PC-Q33 Mini ITX cases.

When is an SoC not an SoC? When it is the GIGABYTE X99-SOC Champion

Subject: Motherboards | March 20, 2015 - 06:31 PM |
Tagged: gigabyte, x99-soc champion, Intel, X99

Relatively new to the market is the $360ish Gigabyte X-99-SOC Champion, expensive compared to previous Intel boards but a decent price for an X99 board.  It has four PCIe 16x slots of which two can only run at 8x maximum as well as three PCIe 1x slots, a single M.2 and a single SEx connector as well as a half dozen SATA 6Gbps ports which can run in RAID and another 4 which are only able to run in AHCI mode.  There are no C-type connectors but there are a plethora of USB 3.0 and 2.0 ports as well as a Thunderbolt header.  This is definitely a board for power users and manual overclockers as you can see in Hardware Canucks review here

You can also expect to see Morry's review of this Gigabyte board in the very near future.

"GIGABYTE's X99-SOC Champion seems to have everything it takes to become a legendary motherboard. It has high end overclocking built into its bones and a low price but will that lead to success?"

Once pirated, always pirated? Microsoft muddles the Win10 upgrade news

Subject: General Tech | March 20, 2015 - 12:18 PM |
Tagged: windows 10, microsoft, confusion

Slashdot has linked to news out of Microsoft that the option to upgrade your non-genuine version of Win7, 8 or 8.1 to Windows 10 is not as clear cut as it sounded earlier in the week.  Microsoft stated in the interview that "they will remain in a “non-genuine” status and Microsoft will not support them".   This is more than a little odd if the stated purpose of this move, to reduce piracy rates across Asia, is correct as there is little to no reason to upgrade if your PC still remains unsupported.  Perhaps there is some sort of disconnect at Microsoft in which they think that one look at their new OS and Store will cause an epiphany in lifelong software pirates and they will leap at the opportunity to pay for Windows 10?

As Microsoft declined to elucidate further we really have no idea what they mean when they state that your Windows will remain unlicensed.  Will you simply have the same Reduced Functional mode, the black desktop overwrite that appears on non-genuine Windows currently?  Will you get all, some or none of the security updates?  Will it simply refuse to boot after a certain amount of time?  All in all it seems that Microsoft could have just skipped their original announcement as nothing seems to have changed.

This_Copy_of_Windows_is_not_Genuine.png

"When Microsoft confirmed it will offer free Windows 10 upgrades to pirates worldwide, many were shocked. VentureBeat has been trying to get more details from the company, which disclosed today that after PCs with pirated copies of Windows 7 and Windows 8.1 are upgraded to Windows 10, they will remain in a 'non-genuine' status and Microsoft will not support them."

A TITANic roundup of GPUs

Subject: Graphics Cards | March 19, 2015 - 03:20 PM |
Tagged: titan x, nvidia, gtx titan x, gm200, geforce, 4k

You have read Ryan's review of the $999 behemoth from NVIDIA and now you can take the opportunity to see what other reviewers think of the card.  [H]ard|OCP tested it against the GTX 980 which shares the same cooler and is every bit as long as the TITAN X.  Along the way they found a use for the 12GB of VRAM as both Watch_Dogs and Far Cry 4 used over 7GB of memory when tested at 4k resolution though the frame rates were not really playable, you will need at least two TITAN X's to pull that off.  They will be revisiting this card in the future, providing more tests for a card with incredible performance and an even more incredible price.

14265930473m7LV4iNyQ_1_6_l.jpg

"The TITAN X video card has 12GB of VRAM, not 11.5GB, 50% more streaming units, 50% more texture units, and 50% more CUDA cores than the current GTX 980 flagship NVIDIA GPU. While this is not our full TITAN X review, this preview focuses on what the TITAN X delivers when directly compared to the GTX 980."

Dammit Gabe, what did we do to you to deserve this?

Subject: General Tech | March 19, 2015 - 01:50 PM |
Tagged: sad, half life 3, gaben

Gabe, once again, will not confirm or deny the possibility of another Half Life game but did imply in an interview that there are no teams currently working on one.  The reason is sad but obvious, as our sometimes maligned Raptr posts have shown, DOTA 2 and CS:GO make up over 10% of the time spent gaming by those with Raptr installed and at the time this article was written 14% of online Steam users are playing those games.  That translates to a lot of hats being sold and a lot of money coming into Valve; significantly more than would come from a new Half Life thanks to the ongoing nature of those online games and the market they have created.

You can catch the interview from the links on Slashdot but stating that this is the end of single player focused games from Valve is an overstatement.  The online gaming market is more lucrative but there is still a market for those of us who prefer stories to online bragging rights and some of the work they have done on current game engines should be translatable to a financially viable single player game or ten.

"Half-Life 3 is undoubtedly one of the most anticipated games in history. While Valve transitioned from the revolutionary series that brought the company most of its original success, to online games like Team Fortress, Dota and Left 4 Dead, people still desperately want to believe that there is more coming for Half-Life."

Windows 10 Build 10041 Released to Insiders

Subject: General Tech | March 18, 2015 - 05:35 PM |
Tagged: windows 10, microsoft, build 10041

It has been a long time coming, but the new preview build of Windows 10 has been released. 10041 can be installed for users on the “Fast” ring, leaving users who opt into “Slow” to be on 9926 for a bit longer. You know, the wise enthusiast learns from their mistakes, but the smart enthusiast learns from the mistakes of others. At any rate, pun intended, a few things have changed in this build, but I expect that most of it is under the hood.

windows-10.png

On the user-facing side though, the Start menu has been modified to include transparency and Virtual Desktops can now support dragging windows between instances (or onto the + to create a new Virtual Desktop with that window in it). Each update, I have attempted to use Virtual Desktops but I have never stuck with it. Rather than being organized, it felt separated, which gave the impression that I was wasting more time context-switching than if I just sifted through cluttered windows. As always, I will give it another chance with 10041. Perhaps I am just using it wrong. We'll see.

There are some known bugs in this version, like always, so read up on it before making the update if your machine is important. I mean, even 9926 has some noticeable problems that are getting annoying, so you might even be net-positive, but look before you leap. That is, unless you are on an unimportant device or are amused by bugs and you want the newest nowest yesterday.

Speaking of which, as previously discussed, Microsoft intends to speed up the rate of “Fast” builds. Their users seem to want less-stable and more cutting edge builds, so they are hoping to have one or two builds per month.

Also, don't let my posts discourage anyone from trying Windows 10. Just because I need to report on all the issues that I experience (even some that ended up being coincidentally exploded hardware, whoops...) doesn't mean that I am casting shame on it. Ultimately, whatever you install Windows on is a device. If that device performs a critical function in your life, then you need to be aware of the issues that I know about. If not, then enjoy the pre-release experience.

I will probably be installing 10041 soon, especially if it brings new Intel and NVIDIA GPU drivers.

Update (March 19th @ 4PM EDT): I installed 10041 last night, and was greeted with two new graphics drivers: one for Intel and another for NVIDIA. Still to early to tell whether it fixed issues or made things worse, but nothing bad happened yet. I am hearing that some people are having difficulty installing audio drivers, though. Allyn linked me to a problem with Xonar cards, and people in the comments of this article mention "audio drivers" in general. About that, all I can say is that my Blue Yeti works fine, as both a mic and sound card.

Get your twitch reflexes back to their peak over the next few weeks as the multiplayer beta for the third instalment of StarCraft 2 kicks off on the 31st.  On that date you will find out if you are invited to participate in the test and get to see the new units as well as the tweaks that have been applied to existing units.  The main page suggests that this episode will focus more on online multiplayer harassment tactics than all out assaults and so units have been altered to reflect that focus.  Blizzard also suggests this beta will go for longer than previous ones have so it will still be a while before we see the next chapter in the single player story.  You can catch the preview movie at Rock, Paper, SHOTGUN.

Get your pirated Windows a letter of marque

If you know a friend that has a friend that might have picked up a copy of Windows from a site of ill repute they still have a chance to redeem their soul.  At WinHEC today Microsoft announced that any eligible version of Windows running on hardware compatible with Windows 10 can also upgrade to a new and fully licensed version of Windows 10 when it is released.  This is an interesting move by Microsoft but there is sense behind the move as it will increase their customer base for purchasing apps from the Microsoft Store and any licensing which may come into effect after the free year they offer.  It also gives them more accurate data on the number of users of Windows and possibly other metadata as well.

"Microsoft will make Windows 10 available as a free upgrade even to pirated copies of other Windows operating systems in China. Terry Myerson of Microsoft's operating systems unit made the announcement at the WinHEC technology conference in Shenzhen, China, and then told Reuters, "We are upgrading all qualified PCs, genuine and non-genuine, to Windows 10.""

Tagged: microsoft, IE, project spartan

First of all, this is possibly the shortest title we have ever made at PC Perspective. I guess I win something? Either way, WinBeta claims that Microsoft has finally said, on the record, that the Internet Explorer branding will not be applied to Project Spartan. The quote is from Chris Capossela, Executive Vice President and Chief Marketing Officer at Microsoft.

ie-wheeee-dead.jpg

And Web Developers say...?

We’re now researching what the new brand, or the new name, for our browser should be in Windows 10," said Capossela. "We’ll continue to have Internet Explorer, but we’ll also have a new browser called Project Spartan, which is codenamed Project Spartan. We have to name the thing.

This quote still seems a little vague for me. While it clearly separates “the new brand” from “Internet Explorer”, it does not definitively say that Project Spartan will not be derived from it (pardon the double-negative). Of course, I think it is safe to say that it will be a wholly new brand, but I don't think this quote changes anything.

By the way, may I recommend “PhoIEnix”? I'm pretty sure no-one tried that name for a web browser before being immediately disputed by Phoenix Technologies. Wow, that's oddly specific to not be a reference to anything, at all, ever...

NVIDIA Announces DIGITS DevBox - 28 TFLOPS, 1300 Watts, $15k

Tagged: nvidia, DIGITS

At GTC, NVIDIA announced a new device called the DIGITS DevBox:

GTC-30.jpg
        

The DIGITS DevBox is a device that data scientists can purchase and install locally. Plugged into a single electrical outlet, this modified Corsair Air 540 case equipped with quad TITAN X (reviewed here) GPUs can crank out 28 TeraFLOPS of compute power. The installed CPU is a Haswell-E 5930K, and the system is rated to draw 1300W of power. NVIDIA is building these in-house as the expected volume is low, with these units likely going to universities and small compute research firms.

Why would you want such compute power?

GTC-29.jpg

DIGITS is a software package available from NVIDIA. Its purpose is to act as a tool for data scientists to manipulate deep learning environments (neural networks). This package, running on a DIGITS DevBox, will give much more compute power capability to scientists who need it for their work. Getting this tech in the hands of more scientists will accelerate this technology and lead to what NVIDIA hopes will be a ‘Big Bang’ in this emerging GPU-compute-heavy field.

More from GTC is coming soon, as well as an exclusive PC Perspective Live Stream set to start in just a few minutes! Did I mention we will be giving away a Titan X???

TechPowerUp has put together a quick overview of the differences of Intel's current offerings for your reference when purchasing a new machine or considering an upgrade.  The older i7-4770K would run you $310 as compared to $338 for the i7-4790K or $385 for an i7-5820K while the i7-4960X would set you back $1025.  Is it worth upgrading your machine if you have an older Haswell, or going full hog to pick up the $1000 flagship model?  The results are presented in a handy format and while perhaps not an in depth review the results are quite striking, especially the performance while gaming.

GTC 2015: NVIDIA Roadmap Shows Pascal with 3D Memory, NVLink and Mixed Precision Compute

Subject: Graphics Cards | March 17, 2015 - 01:47 PM |
Tagged: pascal, nvidia, gtc 2015, GTC, geforce

At the keynote of the GPU Technology Conference (GTC) today, NVIDIA CEO Jen-Hsun Huang disclosed some more updates on the roadmap for future GPU technologies.

GTC-36.jpg

Most of the detail was around Pascal, due in 2016, that will introduce three new features including mixed compute precision, 3D (stacked) memory, and NVLink. Mixed precision is a method of computing in FP16, allowing calculations to run much faster at lower accuracy than full single or double precision when they are not necessary. Keeping in mind that Maxwell doesn't have an implementation with full speed DP compute (today), it would seem that NVIDIA is targeting different compute tasks moving forward. Though details are short, mixed precision would likely indicate processing cores than can handle both data types.

3D memory is the ability to put memory on-die with the GPU directly to improve overall memory banwidth. The visual diagram that NVIDIA showed on stage indicated that Pascal would have 750 GB/s of bandwidth, compared to 300-350 GB/s on Maxwell today.

NVLink is a new way of connecting GPUs, improving on bandwidth by more than 5x over current implementations of PCI Express. They claim this will allow for connecting as many as 8 GPUs for deep learning performance improvements (up to 10x). What that means for gaming has yet to be discussed.

GTC-38.jpg

NVIDIA made some other interesting claims as well. Pascal will be more than 2x more performance per watt efficient than Maxwell, even without the three new features listed above. It will also ship (in a compute targeted product) with a 32GB memory system compared to the 12GB of memory announced on the Titan X today. Pascal will also have 4x the performance in mixed precision compute.

HSA Version 1.0 arrived today

Subject: General Tech | March 17, 2015 - 01:18 PM |
Tagged: hsa foundation, hsa, amd, arm, Samsung, Imagination Technologies, HSAIL

We have been talking about the HSA foundation since 2013, a cooperative effort by AMD, ARM, Imagination, Samsung, Qualcomm, MediaTek and TI to design a heterogeneous memory architecture to allow GPUs, DSPs and CPUs to all directly access the same physical memory.  The release of the official specifications today are a huge step forward for these companies, especially for garnering future mobile market share as physical hardware apart from Carrizo becomes available.

Programmers will be able to use C, C++, Fortran, Java, and Python to write HSA-compliant code which is then compiled into HSAIL (Heterogeneous System Architecture Intermediate Language) and from there to the actual binary executables which will run on your devices.  HSA currently supports x86 and x64 and there are Linux kernel patches available for those who develop on that OS.  Intel and NVIDIA are not involved in this project at all, they have chosen their own solutions for mobile devices and while Intel certainly has pockets deep enough to experiment NVIDIA might not.  We shall soon see if Pascal and improvements Maxwell's performance and efficiency through future generations can compete with the benefits of HSA.

The current problem is of course hardware, Bald Eagle and Carrizo are scheduled to arrive on the market soon but currently they are not available.  Sea Islands GPUs and Kaveri have some HSA enhancements but with limited hardware to work with it will be hard to convince developers to focus on programming HSA optimized applications.  The release of the official specs today is a great first step; if you prefer an overview to reading through the official documents The Register has a good article right here.

hsa.PNG

"The HSA Foundation today officially published version 1.0 of its Heterogeneous System Architecture specification, which (if we were being flippant) describes how GPUs, DSPs and CPUs can share the same physical memory and pass pointers between each other. (A provisional 1.0 version went live in August 2014.)"

360mm of radiator; the Thermaltake Water 3.0 Ultimate

Tagged: thermaltake, Water 3.0 Ultimate, watercooling, AIO

Using the Asetek Gen 4 pump and a radiator measuring 393mm x 120mm x 27mm the Thermaltake Water 3.0 Ultimate is a large cooler designed for serious overclockers.  The fans are rated at 99CFM and are set up properly with PWM connections to balance noise and performance.  Overclockers Club increased their i7-4770K to 4.2GHz and this cooler kept the CPU at an impressive 67 °C, topping the charts of the coolers they have tested previously.  They managed to get the chip running at 4.5GHz on 1.241 volts which raised the temperature to 75 °C but that was the highest frequency that particular i7-4770K could reach.  Check out their full review here.

18.jpg

"Cooling capacity is dependent on air flow and the Ultimate has you covered. You have close to 300CFM of air at your command, so expect to notice the fans when you crank up the heat and with a cooler this size, a little fan noise just goes with the territory. Thermaltake has refined a few components to make the installation about as easy as it can be. The low profile Asetek pump looks good and is quiet. Even at a 4.5GHz overclock, the Ultimate still has some thermal room if your chip can handle a higher overclock."

A few years back Ryan reviewed the Nerdytec COUCHMASTER, even longer ago The Tech Report played with the SumoSac and there are still ButtKickers out there for sale.  Now you can pick up the brightly coloured AKRACING AK-6011 Gaming Chair which is style after the bucket seats found in many sports cars.  Neoseeker picked one up and assembled it to see just how comfortable it and the two included pillows actually are.   After two months of usage they are quite happy with the comfort and sturdy design of the chair, so if you really want to make a statement you can pick one up from Amazon, there are different colour schemes available if the only thing that you find odd about this product is the shade of green they used.

"While we aren't strangers to reviewing gaming peripherals, we haven't yet had the chance to take one of AKRACING's premium gaming chairs for a spin. The brand might ring a bell for readers familiar with eSports. Modeled after the seats used in race cars, AKRACING looks to blend fast lane sensibilities with the ergonomic features that users come to expect from any comfortable chair. On our review today is the AKRACING AK-6011 in a two-tone black and green color scheme with two extra pillows to better customize proper sitting posture.

The Samsung 840 Pro was the last SSD standing in The Tech Report's experiment with a final score of over 2.4 petabytes written. Granted, only one (or two in the case of the Kingston HyperX) of each model participated, which means that one unit could have been top of its batch and another could have been bottom -- and can simply never know. What it does say, however, is that you really should not be worried about writing your SSD to death under normal (or even modestly abnormal) conditions.

This almost looks like one of our Frame Rating charts.

Again, that whole warning (above) about “this could be 100% binning luck” still holds true. Even so, here is the final ranking of contestants!

  1. Samsung 840 Pro (256GB)
  2. Kingston HyperX 3K (240GB with Compression)
  3. Corsair Neutron GTX (240GB)
  4. Samsung 840 (No Suffix and 250GB)
  5. Intel 335 (240GB)
  6. Kingston HyperX 3K (240GB)

The Tech Report notes that the Samsung drives did not warn users through SMART as much as their competitors. In both cases, death from write wearing was abrupt, albeit far into the future. I'd wonder what is next for them, but part of me expects that they never want to run anything like this again.
