The graphics core of new CPUs used to have issues on Linux at launch but recently this has become much less of an issue.  The newly released Iris Pro on the 5770C follows this trend as you can see in the benchmarks at Phoronix.  The OpenGL performance is a tiny bit slower overall on Linux, apart from OpenArena, but not enough to ruin your gaming experience.  With a new kernel on the horizon and a community working with the new GPU you can expect the performance gap to narrow.  Low cost gaming on a Linux machine becomes more attractive every day.

NVIDIA SHIELD; Feeling Hot! Hot! Hot!

Tagged: nvidia, shield tablet, recall

NVIDIA SHIELD tablets which were sold over the past 12 months are being recalled by NVIDIA as there is a risk that the battery could overheat, possibly posing a fire hazard and of course proving they should never be used on a re-entry vehicle.  You will need to ensure that your SHIELD is running the newest OS, if not you will need to run the tablet long enough to update as older OS versions do not report the serial number, which you need to enter if you want a free replacement from NVIDIA.  Visiting www.nvidia.com/support/tabletrecall will give you the steps to request a replacement if you want one.  So far there do not seem to be any reports of flaming NVIDIA users but you should probably not risk it.

"NVIDIA today announced a voluntary recall of its SHIELD 8-inch tablets that were sold between July 2014 and July 2015, which the company will replace. NVIDIA has determined that the battery in these tablets can overheat, posing a fire hazard. The recall does not affect any other NVIDIA products."

Microsoft Rolls Out Windows SDK for Build 10240

Subject: General Tech | July 30, 2015 - 03:58 PM |
Tagged: microsoft, windows, windows 10, visual studio

July 29th started the official roll-out of Windows 10 and, for Windows Insiders, was pretty much “Wednesday”. We already had everything of relevance by Monday on the OS side of things, and not even a security patch landed in our Windows Update queue. It was not the only thing that Microsoft launched today, though. While Visual Studio 2015 was released last week, it said that it was not compatible with pre-10240 SDKs and would delete them during the installation process and you will be unable to develop SDK apps until the one for 10240 launches on July 29th.

microsoft-vs-logo.png

So, coincident with the OS release, Microsoft finally published the 10240 Windows SDK. Now, if you run Visual Studio 2015's installer, it will install the new SDK directly. You do not need to download it from a secondary source. These headers and libraries are placed in the “Windows Kits” folder of your 32-bit Program Files directory... ironically, without deleting the previous SDKs that it threatened to, when run before July 29th. Go figure.

Also, even though DirectX 12 has been in the Windows SDK for quite some time, Microsoft has, also, finally released code examples and they put them on their GitHub page. These samples teach you how to do things like draw a triangle, manage DirectX 11-era contexts alongside DirectX 12 ones in your application, and create an n-body gravity simulation. They welcome pull requests for fixes, although they might appreciate new samples as well.

Powercolor has a soundcard; check out the Devil HDX

Subject: General Tech | July 30, 2015 - 02:19 PM |
Tagged: devil hdx, powercolor, audio, sound card, opamp

Yes, PCIe soundcards are still being made and Powercolor's Devil HDX is up for review on Overclockers Club.  As with most new cards this one features three OPAMPs which can can be removed and swapped with another to change the sound that is sent to your headset or speakers.  On the back are a 124db rated 6.3mm headphone jack, left and right RCA jacks, Coax output, and an optical output.  The daughtercard sports 5 standard analog 3.5mm jacks to give you 7.1 surround sound support if you have the speakers for it.  It is about $160 so make sure you have ears that are good enough to deserve high end sound, for many users this might be a bit of overkill.

"Setup as a stand alone solution, the Devil HDX gets to play in the best of both worlds with 124dB rated performance from the parent card and the option of running 7.1 sound through the addition of the daughter card. Here is my only beef with the Devil HDX. I know these are options that add cost, but when cultivating a brand it would just add to the package."

Happy Sysadmin Day, now put Win10 on my work lappy immediately

You are nowhere near as fed up with Win10 stories as you will be in a week or so sit down and get reading.  So far the biggest new issue has been those who have over 512 apps in their Start menu, not inconceivable but certainly not common.  Over at The Register a story has been put up covering Win10 by a person who admits to having 4,000 open browser tabs and sending the machine into hibernation in that state.  Their experiences show that Win10 doesn't care and even likes this sort of abuse as long as it is on an SSD.  That is not to say all is good, for there is still the technicolour yawn which is the new Start menu and the disturbing tendency for the OS to call on mom more often than Norman Bates.  Read the full article to see the good, bad and bothersome.

Maybe stick with last years Pebble Steel for now?

The Register tried out the new Pebble Time which features a colour e-paper Gorilla glass screen for better visibility outdoors, a battery which will last a full week, waterproofing to 90' and all for a $200 price tag.  With over 8000 apps for the device it offers most of the functionality of the Apple watch for a fraction of the price.  Certain features it lacks such as a heart rate monitor or GPS can be added by using Smartstraps, which not only allows the watch to stay on your wrist but also adds functionality as well.  The improvements were noticeable but The Register preferred last years Steel but if you are in the market for a smartwatch you might be wise to hold on as the new Pebble Time Steel is due out in the near future.

Breaking: Intel and Micron announce 3D XPoint Technology - 1000x Faster Than NAND

Subject: Storage | July 28, 2015 - 12:41 PM |
Tagged: XPoint, non-volatile RAM, micron, memory, Intel

Everyone that reads SSD reviews knows that NAND Flash memory comes with advantages and disadvantages. The cost is relatively good as compared to RAM, and the data remains even with power removed (non-volatile), but there are penalties in the relatively slow programming (write) speeds. To help solve this, today Intel and Micron jointly launched a new type of memory technology.

XPoint.png

XPoint (spoken 'cross point') is a new class of memory technology with some amazing characteristics. 10x the density (vs. DRAM), 1000x the speed, and most importantly, 1000x the endurance as compared to current NAND Flash technology.

2303661_3D_XPoint_Die.jpg

128Gb XPoint memory dies, currently being made by Intel / Micron, are of a similar capacity to current generation NAND dies. This is impressive for a first generation part, especially since it is physically smaller than a current gen NAND die of the same capacity.

Intel stated that the method used to store the bits is vastly different from what is being used in NAND flash memory today. Intel stated that the 'whole cell' properties change as a bit is being programmed, and that the fundamental physics involved is different, and that it is writable in small amounts (NAND flash must be erased in large blocks). While they did not specifically state it, it looks to be phase change memory (*edit* at the Q&A Intel stated this is not Phase Change). The cost of this technology should end up falling somewhere between the cost of DRAM and NAND Flash.

IMFT.jpg

3D XPoint memory is already being produced at the Intel / Micron Flash Technology plant at Lehi, Utah. We toured this facility a few years ago.

Intel and Micron stated that this technology is coming very soon. 2016 was stated as a launch year, and there was a wafer shown to us on stage:

DSC03273.JPG

You know I'm a sucker for good wafer / die photos. As soon as this session breaks I'll get a better shot!

There will be more analysis to follow on this exciting new technology, but for now I need to run to a Q&A meeting with the engineers who worked on it. Feel free to throw some questions in the comments and I'll answer what I can!

*edit* - here's a die shot:

Added note - this wafer was manufactured on a 20nm process, and consists of a 2-layer matrix. Future versions should scale with additional layers to achieve higher capacities.

RTM? Satya don't need no steenking RTM

Subject: General Tech | July 28, 2015 - 12:41 PM |
Tagged: microsoft, windows 10

With not many hours left until launch, Windows 10 is still very obviously a service that is sill being serviced and the pressure is on at Microsoft.  NVIDIA users have discovered that having a clearly drawn display is not something they are likely to have by launch day, much to the amusement of us AMD users.  Until this week those used to uninstalling programs with the Control Panel as opposed to the new procedure of heading to Settings -> System -> Apps & features will find they are punished for their temerity with a Windows Explorer crash, certainly an interesting choice to reinforce the new behaviour.  Less common, though still frequent enough for The Register to make note of and for a patch to be released yesterday is a similar crash if you were to disable an active network connection manually.

Surface users may have noticed new firmware arriving to mitigate some of the compatibility issues Windows 10 testers have used, though there is not that much time left to test them en masse, the fact that the tablets were built by Microsoft should help ensure the updates are stable and useful.  Not so much for other tablets as The Register shows in this story.

Creating a new version of an OS is a non-trivial task and for the most part Windows 10 should be ready for a consumer release this week.  Microsoft have changed a lot about the look and function of Windows and made even more changes to their business model and licensing.  The real hurdle is Enterprise, the huge customer base that ignored Windows 8(.x) and to a lesser extent Windows 7.  With the stability and functionality of the OS already in question, will the poorly communicated changes to the licensing models of Windows 10 mean that we will once again see extremely slow or non-existent adoption in Enterprise and even SMB for that matter?

alfred_e_neuman.jpg

"Build 10240, which was released to the Windows Insider program two weeks ago, is widely considered to be the "release to manufacturing" (RTM) build, even though Redmond itself says the RTM concept doesn't apply in its brave new world of Windows as a Service."

[H]ard|OCP have set up their testbed for a 4K showdown between the similarly priced GTX 980 Ti and Radeon R9 Fury X with the $1000 TITAN X tossed in there for those with more money than sense.  The test uses the new Catalyst 15.7 and the GeForce 353.30 drivers to give a more even playing field while benchmarking Witcher 3, GTA V and other games.  When the dust settled the pattern was obvious and the performance differences could be seen.  The deltas were not huge but when you are paying $650 + tax for a GPU even performance a few frames better or a graphical option that can be used really matters.  Perhaps the most interesting result was the redemption of the TITAN X, its extra price was reflected in the performance results.  Check them out for yourself here.

Morry likes big coolers and Noctua is one of his preferred brands when he wants to test the tensile stregth of a motherboard.  Not all of Noctua's coolers are up to his preferences, such as the slender NH-L9x65, a waif-like 413g with the fan attached and a cute 95x95x79mm in size with a 14mm lift from that fan.  TechPowerUp's testing shows that the fan is quite quiet even when spinning at full speed but even still the temperatures of the i7-4770K it was cooling were the highest on the charts.  If you are cooling a CPU with a lower TDP in a small case, or even a 4770K then check out this review, the NH-L9x65 is a little expensive but certainly usable.

"Noctua's new NH-L9x65 is a low profile, small form-factor cooler. When I say small, I mean tiny as it is only slightly larger than the Intel stock heatsink, which is surprising and begs me to question its maximum potential. While performance most likely won't be its strong point, there is a chance this pint-sized offering will have a few surprises in store"

Don't want Win10 patches? We have a patch for that

Tagged: microsoft, windows 10

Microsoft's decision to push out updates to non-enterprise Windows 10 without user intervention or even notification has been a bit of a hot topic recently.  While those of us who have been supporting machines for a while have all seen a bad Windows update or 10 which render machines unusable, however we have also seen machines over 100 updates behind that are completely riddled with malware, trojans and other nasties which would have been blocked if those updates had been applied.

Whichever side of that debate you fall on, thanks to the nosy reporters at The Register you now can have a choice.  They've posted a link to the "Show or hide updates" troubleshooter package in this recent article, a tool from Microsoft which would allow you to hide certain updates before they were installed and ensure that they are not installed in the future.  Patch Tuesday is gone but there will still be people keeping track of which updates are released so that if you encounter an issue you can roll back and hide that update.  Of course, that assumes you enabled System Restore, which is has been disabled by default in Windows 10.

As always you should take these leaks with a bit of salt but if they are accurate Skylake may well offer enough enhancements to make a convincing argument for buying a new machine.  The GPU portion of the high end mobile processors will be 34-41% faster than the models available now, with the desktop seeing a moderate 28% jump for those who do not have an add-in card.  The low powered mobile model's performance is not much improved over the previous generation but the claimed 80% reduction in power usage is more than enough to make up for that.

SPECint benchmarks show that Skylak will offer a performance boost a bit over 10% but the added 1.4 hours of battery life is rather impressive, even the desktop part is more efficient with a 65W TDP.  As for accessories, Skylake will support 4k cameras and new and improved RealSense 3D cameras, Wake on Voice support and improved touch sensors.  You can see the other two leaked slides at FanlessTech.

If you think about price when you think about Chromebooks, then Microsoft is hoping to have options in Windows 10 for you. Laptops that boot into a web browser still have interesting security and ease-of-use implications, which this will not address. From the previously mentioned cost standpoint though, full-featured Windows laptops can get down to those levels, especially when Microsoft helps out on the OS license fees.

This is the more-expensive Chromebook running Google Chrome OS.

Acer will launch their Cloudbook line in August, with 11-inch and 14-inch versions, starting at $169. While you can get Chromebooks for $149, Acer's Chromebook 11 is currently selling for $179.99, which puts the Windows 10 model $10 cheaper than it. On the other hand, we don't know anything about the system specifications. It is possible that the Cloudbook could have less than an Intel Celeron with HD Graphics and 2GB of RAM -- but we hope not.

The Acer Cloudbook will not make Microsoft's July 29th launch date of Windows. Instead, as previously stated, look for it some time in August. Prices start at $169 USD.

Rumor: NVIDIA Pascal up to 17 Billion Transistors, 32GB HBM2

Subject: Graphics Cards | July 24, 2015 - 12:16 PM |
Tagged: rumor, pascal, nvidia, HBM2, hbm, graphics card, gpu

An exclusive report from Fudzilla claims some outlandish numbers for the upcoming NVIDIA Pascal GPU, including 17 billion transistors and a massive amount of second-gen HBM memory.

According to the report:

"Pascal is the successor to the Maxwell Titan X GM200 and we have been tipped off by some reliable sources that it will have  more than a double the number of transistors. The huge increase comes from  Pascal's 16 nm FinFET process and its transistor size is close to two times smaller."

Pascal's 16nm FinFET production will be a major change from the existing 28nm process found on all current NVIDIA GPUs. And if this report is accurate they are taking full advantage considering that transistor count is more than double the 8 billion found in the TITAN X.

PlanarFinFET.jpg

And what about memory? We have long known that Pascal will be NVIDIA's first forray into HBM, and Fudzilla is reporting that up to 32GB of second-gen HBM (HBM2) will be present on the highest model, which is a rather outrageous number even compared to the 12GB TITAN X.

"HBM2 enables cards with 4 HBM 2.0 cards with 4GB per chip, or four HBM 2.0 cards with 8GB per chips results with 16GB and 32GB respectively. Pascal has power to do both, depending on the SKU."

Pascal is expected in 2016, so we'll have plenty of time to speculate on these and doubtless other rumors to come.
