If you are reading this from the US you probably have an opinion about the news out of the FCC today and should probably express that opinion to your various congress critters, even though Ajit Pai has stated he won't listen.  As a backup plan you might want to take a read through this article over at Hack a Day which describes how you can set yourself up as your own ISP, aka an Autonomous System.  The process is nowhere near as simple as setting up a home internet connection and you will need some dedicated equipment you may or may not have lying around.  Those who live outside the USA should still take a look as there is some very interesting learning material in the article.

HP's Ryzen Mobile Powered Envy X360 Is Available Now

Subject: General Tech, Mobile | November 20, 2017 - 08:25 PM |
Tagged: windows hello, stylus, ryzen mobile, Ryzen 5 2500U, hp, convertible, amd

Last month AMD formally launched its Ryzen Mobile APUs with partners Acer, HP, and Lenovo announcing that systems using the new processors would be out by the end of the year. The first system to become available for purchase appears to be the HP Envy X360 convertible notebook which is available with a Ryzen 5 2500U APU. The 15.6” 2-in-1 starts at $574.99 (at time of writing) and thankfully appears to take full advantage of the AMD processor.

HP Envy X360 with Ryzen 5 2500U.png

The HP Envy X360 was spotted by Anandtech who noted that the notebook is currently being sold at HP.com as well as brick and mortar Best Buy stores. The notebook is part of the company’s higher end Envy brand. It weighs in at 4.75 pounds and measures 14.16” x 9.8” x 0.77”. The 360° hinge allows the touchscreen display to flip around to lay flat with the underside of the keyboard enabling tablet mode. The top half with thin bezels holds the 15.6” 1920 x 1080 display and IR capable Windows Hello camera. The bottom half holds the rest of the hardware and features a backlit island-style keyboard with numpad, a wide trackpad, and the various I/O ports around the edges including USB-C 3.1 Gen 1 with DisplayPort 1.4 and USB Power support (for charging), two full size USB 3.1 Gen 1 ports, HDMi, and a headset jack. Other features include Bang and Olufsen audio with dual speakers and a stylus that can be used with Windows Ink, One Note, and other apps.

Internal specifications include the above-mentioned Ryzen 5 2500U, up to 16 GB of dual channel 2400 MHz memory, and mechanical and solid-state storage options. The base model of this laptop starts at 8 GB DDR4 at 2400 MHz (2 x 4GB) and 1TB of 7200 RPM hard drive storage. Users can configure the notebook with up to a 1TB NVMe SSD or a combination of SATA hard drive and NVMe M.2 drives. The HP Envy X360 also features Intel 802.11ac Wi-Fi and it is all powered by a 3-cell 55.8 Wh battery. The APU is a 15W TDP chip with four Zen-based CPU cores (eight threads) running at 2 GHz base and up to 3.6 GHz boost, a RX Vega-based GPU clocked at up to 1100 MHz with 8 CUs (512 cores), and 6 MB of cache (2MB L2 and 4MB L3).

The HP Envy X360 15z Touch convertible laptop is available now starting at $574.99 and going up to $1374.99 fully loaded with Windows 10 Pro.

In all this looks to be a good design win for AMD is a promising start for the future of Ryzen Mobile. Thankfully the APU appears to be running at its full 15W TDP and is not being held back by single channel memory like past AMD mobile chips have allegedly been. I am looking forward to seeing what AMD’s other partners have to offer. Until then though, we have a Ryzen 7 1700 powered Asus ROG gaming laptop to ponder about!

Toshiba is not about to become an Asustek satellite company, yet

Toshiba has been having a rough year, but according to what The Inquirer was been able to find out they are not quite ready to sell their computer business to AsusTek or Lenovo quite yet.  The issue stems from their pending removal from the Tokyo Stock Exchange next March do to falling below certain financial thresholds.  Toshiba is hoping that the pending $18bn sale of its semiconductor business will complete before the end of this fiscal year, which would see them into the clear, but it is uncertain that that will be the case.  Toshiba have completed a $114m sale of their TV business, which means there is not that much left for them to divest other than their computer business.  On the other hand if they sell the last of their assets there is no need to remain listed on the stock exchange.  We shall see what happens as the deadline approaches.

NVIDIA Discontinues Mental Ray One Year After Relaunch

Subject: General Tech | November 19, 2017 - 02:15 PM |
Tagged: nvidia, mental ray, iray

Back in SIGGRAPH 2016, NVIDIA announced that they would take control of Mental Ray’s licensing and development. The new product was in beta at the time, boasting a new global illumination solver that was 4x faster on CPUs than the previous method, and 25.9x faster when you add a pair of Quadro M6000s into the mix. Access to the beta was free until it launched, which happened in Autumn 2016.

We’re now in Autumn 2017, and NVIDIA is discontinuing the product.

nvidia-2016-mentalray-benchmark.png

NVIDIA is not leaving the rendering market, though. The graphics vendor has several products in that space, including the very-similar Iray. In fact, it was kind-of odd to see NVIDIA maintain both products with some weird cross-overs, like how they’re bundled on 3D Studio Max for the same price as either product purchased individually in Maya. They also maintain the OptiX and IndeX APIs, which is used all over the place, even for non-graphics workloads. (VRWorks Audio, for instance, uses OptiX to ray-trace video game audio for environmental effects, which is a fairly good model of high-frequency sounds.)

Current users of the Mental Ray plug-in, or those who purchase a license before the 20th of November, will receive “maintenance releases” through 2018 (presumably while they plan their transition elsewhere). These updates will be “bug fix” updates, although NVIDIA does state that one of them will introduce compatibility for Volta-based GPUs.

If you already own a license to Mental Ray, and you will need it for longer than the time left on your subscription, then you will need to contact NVIDIA for an extension. They’re not going to just throw you out if your license expires in December, but you have obligations through February (or something).

Intel Z390 Chipset Spotted on Upcoming SuperMicro Motherboard

Subject: General Tech, Chipsets | November 16, 2017 - 02:03 PM |
Tagged: Intel, Z390, coffee lake, thunderbolt 3

Last month a leaked roadmap appeared online teasing several upcoming Intel chipsets slated for release early next year. The new chipsets were optimized for Coffee Lake processors and include H370, B360, and H310 in the first quarter and Q370 and Q360 (for enterprise customers) in Q2 2018. The most interesting chipset however is Z390 which was mentioned in the roadmap but with hardly any details at all about it. Thanks to a SiSoft database listing and a couple recent leaks there is now slightly bit more information on the upcoming chipset.

Sisoft-Supermicro_Intel Z390.png

Specifically, the Intel Z390 chipset was spotted in a SuperMicro C7Z390-PGW motherboard along with an undetected 92W Coffee Lake 6 core / 12 thread processor (perhaps SiSoft is simply incorrectly reading a 8700K or it’s an unreleased slightly more power efficient SKU). More interesting though is the continuing tease of possible 8 core (16 thread) consumer Core processors being released for these new Z390 chipset-based motherboards. The rumor mill is going all in on salt futures on this one it seems. What we still don’t know is what architecture these rumored 8 core chips will use, whether Coffee Lake or Cannon Lake (I’m leaning towards CNL but an 8 core Coffee Lake chip, while large, is not out of the question.)

The Z390 chipset will reportedly add a SoundWire digital audio interface with quad core DSP, integrated Intel Wireless AC (Wi-fi + BT CNVi), integrated SDXC 3.0, and Thunderbolt 3.0 with DisplayPort 1.4 support (using the Titan Ridge controller). The chipset further supports C10 and S0ix

In the last bit of Intel chipset rumors for today, rumors are also spreading suggesting that Intel may be moving up the launch of the Z390 chipset to the first quarter of next year to better compete with AMD and its Pinnacle Ridge (Ryzen 2000 / Zen+) processors and Promontory X400 series chipsets (e.g. X470 and B450) which are allegedly coming in January. Basically, it’s going to be a crazy CES for motherboard and processor soft launches and product teases / announcements!

What are your thoughts on Z390 being spotted in the wild this early?

The Wolfensteins of Vulkan in the spotlight

Tagged: gaming, Wolfenstein 2, vulkan, amd, nvidia

[H]ard|OCP took a close look at the new Wolfenstein game, covering the new graphics options which appear in the menus as well as the bugs that could be caused by then, not to mention the benchmarking.  For this Vulkan game they chose three AMD cards and four NVIDIA cards to test with a variety of thsoe options enabled as well as looking at the effect resolution has on your performance.  As we have seen in other recent games, AMD's Vega 64 is a strong contender at 4K resolutions, surpassing the GTX 1080 but not quite matching its 1080 Ti brother.  It is also worth noting this game loves VRAM, in fact 8GB is not enough for Uber settings.  Read through the full review for performance numbers as well as insight into the best graphics settings to chose.

The phones are taking all the DRAM memory

Tagged:

Once again we have bad news about RAM prices for consumers and great news for manufacturers.  The price rose an average of 5% this past quarter, continuing the upwards trend we have been seeing for quite some time now.  The supply shortage is due to several factors but the dominant one would be the smartphone industry which has vastly increased overall demand for DRAM.  Currently demand far outstrips supply, though as new fabs come online and current ones complete their upgrades to new process technology we should hopefully see a levelling in prices.  As The Inquirer points out, this is not bad news for Samsung, SK Hynix or Micron who are all seeing very nice profits. 

Next time you are thinking about purchasing that shiny new phone, think about your computer for a moment before pressing add to cart.

A win for the rebels against EA's Empire

Subject: General Tech | November 14, 2017 - 05:09 PM |
Tagged: gaming, ea, Star Wars Battlefront 2

Loot boxes may look good on paper as a way to generate extra revenue from a game but in reality they are incredibly unpopular with those who buy games.  Originally EA had set the price of unlocking your first playable hero at 60,000 in game credits.  According to the math done in the article Slashdot linked to, that would entail around 40 hours of gameplay assuming you never used any for the various other unlocks EA charges credits for.  As EA limits the amount of credits you can earn at one time in arcade mode, most of those hours would need to be spent in multiplayer games as opposed to enjoying the game in peace and quiet.  Of course, you could always pay money for them, $450 or so would unlock a hero.

In this case EA actually listened to their prospective customers, dropping the credit requirements for heroes by 75%; the loot boxes remain of course.

"Most importantly, Electronic Arts today announced that they are reducing the number of credits needed to unlock top characters in the game by 75 percent. Luke Skywalker and Darth Vader will now cost 15,000 credits. Emperor Palatine, Chewbacca and Leia Organa will now cost 10,000 and Iden will cost 5,000."

Speed Metal on the Desktop

Tagged: 3d printing, metal, Desktop Metal

Desktop Metal's new printer follows the same design process as current 3D metal printing, layers of metal powder, wax and a plastic binding agent are sprayed out by an inkjet-like device.  Upon completion of the print, the item is submerged in a debinding fluid which disolves the wax and then spends some time in a furnace to burn off the binding agent and set the powder leaving the final product between 96 and 99.8% metal.  This process is currently handled much more quickly via traditional tool and die, however Desktop Metal told The Register their new printer operates at 100 times the speed of the competition and at a very competitive price to either tool and die or 3D printing.  It will be interesting to see if this applies to a wide enough variety of prints and provides high enough quality to unseat the incumbent processes.

Rumor: Hades Canyon NUC with AMD Graphics Spotted

Subject: General Tech, Processors | November 9, 2017 - 02:30 PM |
Tagged: Skull Canyon, nuc, kaby lake-g, Intel, Hades Canyon VR, Hades Canyon, EMIL, amd

Hot on the heels of Intel's announcement of new mobile-focused CPUs integrating AMD Radeon graphics, we have our first glimpse at a real-world design using this new chip.

HadesCanyon.jpg

Posted on the infamous Chinese tech forum, Chiphell earlier today, this photo appears to be a small form factor PC design integrating the new Kaby Lake-G CPU and GPU solution.

Looking at the standard size components on the board like the Samsung M.2 SSD and the DDR4 SODIMM memory modules, we can start to get a better idea of the actual size of the Kaby Lake-G module.

Additionally, we get our first look at the type of power delivery infrastructure that devices with Kaby Lake-G are going to require. It's impressive how small the motherboard is taking into account all of the power phases needed to feed the CPU, GPU, and HBM 2 memory. 

NUC_roadmap.png

Looking back at the leaked NUC roadmap from September, the picture starts to become more clear. While the "Hades Canyon" NUCs on this roadmap threw us for a loop when we first saw it months ago, it's now clear that they are referencing the new Kaby Lake-G line of products. The plethora of IO options from the roadmap, including dual Gigabit Ethernet and 2 Thunderbolt 3 ports also seem to match closely with the leaked NUC photo above.

Using this information we also now have a better idea of the thermal and power requirements for Kaby Lake-G. The base "Hades Canyon" NUC is listed with a 65W processor, while the "Hades Canyon VR" is listed with as a 100W part. This means that devices retain the same levels of CPU performance from the existing Kaby Lake-H Quad Core mobile CPUs which clock in at 35W, plus roughly 30 or 65W of graphics performance.

core-radeon-leak.png

These leaked 3DMark scores might give us an idea of the performance of the Hades Canyon VR NUC.

One thing is clear; Hades Canyon will be the highest power NUC Intel has ever produced, surpassing the 45W Skull Canyon. Considering the already unusual for a NUC footprint of Skull Canyon, I'm interested to see the final form of Hades Canyon as well as the performance it brings! 

With what looks to be a first half  2018 release date on the roadmap, it seems likely that we could see this NUC or other similar devices being shown off at CES in January. Stay tuned for more continuing coverage of Intel's Kaby Lake-G and upcoming devices featuring it!

A walrus on virtual rollerskates

Jamie Hyneman is pitching a project to build prototype VR roller skates; not as a game but as a way to save your shins while using a VR headset.  The design places motorized wheels under your heel and a track under the ball of your foot which will move your foot back to its starting position if you walk forward.  If all goes as planned this should allow you to walk around in virtual worlds without running into walls, chairs or spectators and perhaps allow games to abandon the point and teleport currently in vogue.  There are a lot of challenges as previous projects have discovered but perhaps a Mythbuster can help out.  You can watch his pitch video over at The Register.

"Hyneman's pitch video points out that when one straps on goggles and gloves to enter virtual reality, your eyes are occupied and you therefore run the risk of bumping into stuff if you try to walk in meatspa ce while simulating walking in a virtual world. And bumping into stuff is dangerous."

If you own a Logitech Harmony Link and registered it then you already know, but for those who did not receive the email you should know your device will become unusable in March.  According to the information Ars Technica acquired, Logitech have decided not to renew a so called "technology certificate license" which will mean the Link will no longer work.  It is not clear what this certificate is nor why the lack of it will brick the Link but that is what will happen.  Apparently if you have a Harmony Link which is still under warranty you can get a free upgrade to a Harmony Hub; if your Link is out of warranty then you can get a 35% discount.  Why exactly one would want to purchase another one of these devices which can be remotely destroyed is an interesting question, especially as there was no monthly contract or service agreement suggesting this was a possibility when customers originally purchased their device.

"Customers received an e-mail explaining that Logitech will "discontinue service and support" for the Harmony Link as of March 16, 2018, adding that Harmony Link devices "will no longer function after this date."

These new in-ear headphones from 1MORE have a single carbon driver for mids and lows with three balanced armatures to handle the high and ultra-high frequencies.  This is not a surround sound implementation but instead an attempt to provide very high quality sound from in-ear monitors.  TechPowerUp tested these Dolby Certified headphones and found them to be an improvement on the already impressive Triple Driver model, even powered by a smartphone; they do not require a DAC or pre-amp to provide great sound.  On the other hand, $200 is steep for this style of headphone so read through the review before jumping on Amazon.
