Demoing improvements to mobile phone networks is difficult. Where an individual vendor such as Intel or AMD can show off an improved CPU architecture mostly by themselves, it takes a lot of cooperation between companies to show off advanced mobile data initiatives.

This is just what Sprint, Qualcomm, and Motorola teamed up to do last week at the Smoothie King Center in New Orleans, Louisiana.

The first part of the story revolves around Sprint’s unique placement in the US mobile network market.  While network operators such as Verizon, ATT, and T-Mobile in the US currently operate their LTE networks on low and mid-band LTE frequencies, the vast majority of Sprint's allocated frequency into the high-band range of 2.5GHz. The reason that Sprint has this spectrum is from their short-lived rollout of WiMax technology with Clear.

High-band frequencies can provide several advantages when deploying technologies enabling Gigabit-class LTE and on the road to 5G.

First, the antenna size needed in the 2.5GHz range is substantially smaller than the antenna size for a more common LTE frequency like 1900MHz. This means that when looking to deploy cellular sites utilizing technologies like 4X4 MIMO antenna arrays, Sprint can make smaller cell sites and be more nimble by placing them in areas where they are seeing substantial network load.

BitFenix Releases the Portal: A Sleek Mini-ITX Enclosure

Subject: Cases and Cooling | March 16, 2017 - 09:34 AM |
Tagged: small form factor, SFX, SFF, Portal, mini-itx, enclosure, case, bitfenix, aluminum

BitFenix has announced the Portal, which is one of the more interesting-looking chassis designs to hit the market in recent memory. Available in both black and white, and with or without a top-mounted window to show off your GPU (thanks to the inverted motherboard layout), the Portal is a sleek mini-ITX enclosure with a smooth, rounded aluminum exterior that is certainly a departure from typical case designs.

portal-masterimage.jpg

One of the design concepts made possible by SFX power supplies is a slimming down of the standard tower concept, which leaving component layout identical. In the case of this mini-ITX mini tower case from BitFenix, you might at first think you are looking at a larger case, but that PSU opening is in fact SFX, and the case is just wide enough to accommodate a standard PCIe graphics card.

portal_ww2.jpg

A smaller mini-ITX case is often more challenging to work in, but here BitFenix has a clever solution with their dual-frame design:

"Designed for ITX Motherboards, the striking key component of the interior is the Dual Frame Design for easy access and quick installation. The inner chamber, equipped with enough space for high-end components, slides into the housing via a ball bearing runner design."

portal_bw2.jpg

The external housing slimply slides off to reveal a standard chassis frame, allowing for easy component installation. Beyond the requirements of mini-ITX motherboard and SFX power supply, the Portal allows for CPU coolers of up to 125 mm, and full size graphics cards up to 300 mm long.

Specifications:

  • Chassis Type: ITX Chassis
  • Colors: Black | White
  • Materials: Aluminum | SECC Steel | ABS | Transparent acrylic
  • Motherboard: Mini-ITX
  • CPU Cooler: Up to 125mm height
  • Graphic Card Length: Up to 300mm
  • Power Supply: SFX Form Factor
  • Storage Capacity: 3.5" HDD x2, 2.5" HDD 1+2
  • Cooling Capacity: Front 120mm x1 (included), rear 80mm x1 (included)
  • Radiator Capacity: (Front) Up to 120mm x1
  • Front I/O ports: USB 3.0 x2 | HD Audio Mic & Headphone
  • Dimensions (with stand): (WxHxD) 247 x 395 x 411 mm (9.72 x 15.55 x 16.18 inches)
  • Weight: 5.81 kg (12.81 lbs)

portal_bw1.jpg

Cooling is another area that has received BitFenix's attention, as they have implemented what they call their "intelligent cooling solution" with the Portal:

"To cool the built-in hardware, the portal is equipped with air inlets at all four corners and the bottom of the housing. The air-permeable inner chamber is further equipped with included 120mm intake and 80mm exhaust fan, for a stable airflow for basic Office and Home Theater PCs."

The BitFenix Portal is available now for $139.99 with your choice of color and window option (product pages already up on Newegg.com).

Ryzen Locking on Certain FMA3 Workloads

Subject: Processors | March 15, 2017 - 05:51 PM |
Tagged: ryzen, Infinity Fabric, hwbot, FMA3, Control Fabric, bug, amd, AM4

Last week a thread was started at the HWBOT forum and discussed a certain workload that resulted in a hard lock every time it was run.  This was tested with a variety of motherboards and Ryzen processors from the 1700 to the 1800X.  In no circumstance at default power and clock settings did the processor not lock from the samples that they have worked on, as well as products that contributors have been able to test themselves.

ryzen.jpg

This is quite reminiscent of the Coppermine based Pentium III 1133 MHz processor from Intel which failed in one specific workload (compiling).  Intel had shipped a limited number of these CPUs at that time, and it was Kyle from HardOCP and Tom from Tom’s Hardware that were the first to show this behavior in a repeatable environment.  Intel stopped shipping these models and had to wait til the Tualatin version of the Pentium III to be released to achieve that speed (and above) and be stable in all workloads.

The interesting thing about this FMA3 finding is that it is seen to not be present in some overclocked Ryzen chips.  To me this indicates that it could be a power delivery issue with the chip.  A particular workload that heavily leans upon the FPU could require more power than the chip’s Control Fabric can deliver, therefore causing a hard lock.  Several tested overclocked chips with much more power being pushed to them seems as though enough power is being applied to the specific area of the chip to allow the operation to be completed successfully.

This particular fact implies to me that AMD does not necessarily have a bug such as what Intel had with the infamous F-Div issue with the original Pentium, or AMD’s issue with the B2 stepping of Phenom.  AMD has a very complex voltage control system that is controlled by the Control Fabric portion of the Infinity Fabric.  With a potential firmware or microcode update this could be a fixable problem.  If this is the case, then AMD would simply increase power being supplied to the FPU/SIMD/SSE portion of the Ryzen cores.  This may come at a cost through lower burst speeds to keep TDP within their stated envelope.

A source at AMD has confirmed this issue and that a fix will be provided via motherboard firmware update.  More than likely this comes in the form of an updated AGESA protocol.

NVIDIA's GeForce 378.78; is this the DX12 driver you have been waiting for?

Subject: Graphics Cards | March 15, 2017 - 03:59 PM |
Tagged: nvidia, GeForce 378.78

AMD has been offering support for DX12 more effectively than NVIDIA in many titles; not enough to consistently surpass the higher end GTX cards but certainly showing improvements.  NVIDIA announce that their new driver, along with optimized support for the new Tom Clancy game will also offer performance increases in DX12 games.  [H]ard|OCP put the numbers referenced in the PR to the test in their recent review.  The news is good for the games which were mentioned but you should not expect any gains in DX11 titles with the new driver as you can see from the benchmarks results.

We have gone from no new System Shock to a pair of them, good news for fans of the series.  The Kickstarter reboot we already know about, with many mixed opinions about the move to the Unreal Engine, however the recently announced System Shock 3 is a totally different beast.  This sequel is being produced by Starbreeze and will not involve crowd sourcing.  Having migrated from a space station to starship it will be interesting to see what location is chosen for the third; as it is in early development they did not let Rock, Paper, SHOTGUN in on the secret.  We anxiously await examples of the art style and other details from Starbreeze and will let you know as they arrive.

Ergonomic keyboards have come in a wide variety of shapes and sizes and tend to be either loathed or loved.  Truly Ergonomic release the tenkeyless board you can see below, a bit of a change from the usual design which separates the keys on a much larger angle and incorporates Kailh Brown switches into the design.  At 234 x 327.6 x 38.1mm (9.2 x 12.8 x 1.5") it is of similar size to most TKL boards and much smaller than other ergonomic designs, especially if you chose to remove the wrist rest.  TechPowerUp tried it out and ran into some strange issues, troubles with USB 3.x connectivity and the ability to brick the keyboard requiring disassembly to return it to working condition.  On the other hand, their wrists were happy with the layout; read the full review here.

Now that's dense storage; single atom storage

Tagged: nm, storage

As we are not going to see scanning tunnelling microscopes included in our home computers anytime soon this experiment is simply proof of the concept that data can be stored on a single atom.  That does not make it any less interesting for those fascinated by atomic storage techniques.  A single atom of holmium can be made to spin either up or down, signifying either a 0 or 1, and that spin state can be 'read' by measuring the vibration of a single iron atom located close by.  The holmium atoms used for storage can be separated by a mere nanometer without interfering with the spin of its neighbours.  The spin state only lasts a few hours but shows that this could someday be a viable storage technology.  You can read more at nanotechweb, who also have links to the Nature article.

AMD Ryzen Community Update Addresses Windows 10 Thread Scheduling, SMT Performance, and More

Subject: Processors | March 13, 2017 - 08:48 PM |
Tagged: Windows 7, windows 10, thread scheduling, SMT, ryzen, Robert Hallock, processor, cpu, amd

AMD's Robert Hallock (previously the Head of Global Technical Marketing for AMD and now working full time on the CPU side of things) has posted a comprehensive Ryzen update, covering AMD's official stance on Windows 10 thread scheduling, the performance implications of SMT, Windows power management settings, and more. The post in its entirety is reproduced below, and also available from AMD by following this link.

AMD_RYZEN.png

(Begin statement:)

It’s been about two weeks since we launched the new AMD Ryzen™ processor, and I’m just thrilled to see all the excitement and chatter surrounding our new chip. Seems like not a day goes by when I’m not being tweeted by someone doing a new build, often for the first time in many years. Reports from media and users have also been good:

  • “This CPU gives you something that we needed for a long time, which is a CPU that gives you a well-rounded experience.” –JayzTwoCents
  • Competitive performance at 1080p, with Tech Spot saying the “affordable Ryzen 7 1700” is an “awesome option” and a “safer bet long term.”
  • ExtremeTech showed strong performance for high-end GPUs like the GeForce GTX 1080 Ti, especially for gamers that understand how much value AMD Ryzen™ brings to the table
  • Many users are noting that the 8-core design of AMD Ryzen™ 7 processors enables “noticeably SMOOTHER” performance compared to their old platforms.

While these findings have been great to read, we are just getting started! The AMD Ryzen™ processor and AM4 Platform both have room to grow, and we wanted to take a few minutes to address some of the questions and comments being discussed across the web.

Thread Scheduling

We have investigated reports alleging incorrect thread scheduling on the AMD Ryzen™ processor. Based on our findings, AMD believes that the Windows® 10 thread scheduler is operating properly for “Zen,” and we do not presently believe there is an issue with the scheduler adversely utilizing the logical and physical configurations of the architecture.

As an extension of this investigation, we have also reviewed topology logs generated by the Sysinternals Coreinfo utility. We have determined that an outdated version of the application was responsible for originating the incorrect topology data that has been widely reported in the media. Coreinfo v3.31 (or later) will produce the correct results.

Finally, we have reviewed the limited available evidence concerning performance deltas between Windows® 7 and Windows® 10 on the AMD Ryzen™ CPU. We do not believe there is an issue with scheduling differences between the two versions of Windows.  Any differences in performance can be more likely attributed to software architecture differences between these OSes.

Going forward, our analysis highlights that there are many applications that already make good use of the cores and threads in Ryzen, and there are other applications that can better utilize the topology and capabilities of our new CPU with some targeted optimizations. These opportunities are already being actively worked via the AMD Ryzen™ dev kit program that has sampled 300+ systems worldwide.

Above all, we would like to thank the community for their efforts to understand the Ryzen processor and reporting their findings. The software/hardware relationship is a complex one, with additional layers of nuance when preexisting software is exposed to an all-new architecture. We are already finding many small changes that can improve the Ryzen performance in certain applications, and we are optimistic that these will result in beneficial optimizations for current and future applications.

Temperature Reporting

The primary temperature reporting sensor of the AMD Ryzen™ processor is a sensor called “T Control,” or tCTL for short. The tCTL sensor is derived from the junction (Tj) temperature—the interface point between the die and heatspreader—but it may be offset on certain CPU models so that all models on the AM4 Platform have the same maximum tCTL value. This approach ensures that all AMD Ryzen™ processors have a consistent fan policy.

Specifically, the AMD Ryzen™ 7 1700X and 1800X carry a +20°C offset between the tCTL° (reported) temperature and the actual Tj° temperature. In the short term, users of the AMD Ryzen™ 1700X and 1800X can simply subtract 20°C to determine the true junction temperature of their processor. No arithmetic is required for the Ryzen 7 1700. Long term, we expect temperature monitoring software to better understand our tCTL offsets to report the junction temperature automatically.

The table below serves as an example of how the tCTL sensor can be interpreted in a hypothetical scenario where a Ryzen processor is operating at 38°C.

TEMPS.png

Power Plans

Users may have heard that AMD recommends the High Performance power plan within Windows® 10 for the best performance on Ryzen, and indeed we do. We recommend this plan for two key reasons: 

  1. Core Parking OFF: Idle CPU cores are instantaneously available for thread scheduling. In contrast, the Balanced plan aggressively places idle CPU cores into low power states. This can cause additional latency when un-parking cores to accommodate varying loads.
  2. Fast frequency change: The AMD Ryzen™ processor can alter its voltage and frequency states in the 1ms intervals natively supported by the “Zen” architecture. In contrast, the Balanced plan may take longer for voltage and frequency (V/f) changes due to software participation in power state changes.

In the near term, we recommend that games and other high-performance applications are complemented by the High Performance plan. By the first week of April, AMD intends to provide an update for AMD Ryzen™ processors that optimizes the power policy parameters of the Balanced plan to favor performance more consistent with the typical usage models of a desktop PC.

Simultaneous Multi-threading (SMT)

Finally, we have investigated reports of instances where SMT is producing reduced performance in a handful of games. Based on our characterization of game workloads, it is our expectation that gaming applications should generally see a neutral/positive benefit from SMT. We see this neutral/positive behavior in a wide range of titles, including: Arma® 3, Battlefield™ 1, Mafia™ III, Watch Dogs™ 2, Sid Meier’s Civilization® VI, For Honor™, Hitman™, Mirror’s Edge™ Catalyst and The Division™. Independent 3rd-party analyses have corroborated these findings.

For the remaining outliers, AMD again sees multiple opportunities within the codebases of specific applications to improve how this software addresses the “Zen” architecture. We have already identified some simple changes that can improve a game’s understanding of the "Zen" core/cache topology, and we intend to provide a status update to the community when they are ready.

Wrap-up

Overall, we are thrilled with the outpouring of support we’ve seen from AMD fans new and old. We love seeing your new builds, your benchmarks, your excitement, and your deep dives into the nuts and bolts of Ryzen. You are helping us make Ryzen™ even better by the day.  You should expect to hear from us regularly through this blog to answer new questions and give you updates on new improvements in the Ryzen ecosystem.

(End statement.)

Such topics as Windows 7 vs. Windows 10 performance, SMT impact, and thread scheduling will no doubt still be debated, and AMD has correctly pointed out that optimization for this brand new architecture will only improve Ryzen performance going forward. Our own findings as to Ryzen and the Windows 10 thread scheduler appear to be validated as AMD officially dismisses performance impact in that area, though there is still room for improvement in other areas from our initial gaming performance findings. As mentioned in the post, AMD will have an update for Windows power plan optimization by the first week of April, and the company has "already identified some simple changes that can improve a game’s understanding of the 'Zen' core/cache topology, and we intend to provide a status update to the community when they are ready", as well.

It is refreshing to see a company publicly acknowledging the topics that have resulted in so much discussion in the past couple of weeks, and their transparency is commendable, with every issue (that this author is aware of) being touched on in the post.

Epic Games Releases Zen Garden Demo for WebAssembly

Subject: General Tech | March 13, 2017 - 08:02 PM |
Tagged: webassembly, ue4, mozilla, epic games

HTML5 was a compile target for Unreal Engine since Unreal Engine 3, but it was supposed to be a bigger push for Unreal Engine 4 then it has been. At the time, Mozilla was pushing for web browsers to be the main source of games. Thanks to Flash, users are even already accustomed to that use case; it’s just a matter of getting performance and functionality close enough to competing platforms, and supporting content that will show it off.

epic-2017-zengardenwebassembly.jpg

That brings us to Zen Garden. This demo was originally designed to show off the Metal API for iOS, but Epic has re-purposed it for the recently released web browser features, WebAssembly and WebGL 2.0. Personally, I find it slightly less impressive than the Firefox demo of Unreal Tournament 3 that I played at Mozilla Summit 2013, but it’s a promising example that big-name engines are taking Web standards seriously again. You don’t get much bigger than Unreal Engine 4.

So yeah... if you have Firefox 52, then play around with it. It’s free.

Dual PSU fans; a revolutionary idea from Enermax?

Tagged: DUOFan, modular psu, enermax, Revolution Duo, 700W

Enermax is bringing back a classic in PSU design, dual fans in a push pull configuration was the standard not even a decade ago.  Their marketing team chose Revolution to describe the new PSU, perhaps missing a chance to refer to it as a Heritage, Pedigree or other such designations that you see on a lot of lifestyle products lately.  The two fans, one 100mm and one 80mm are housed in a casing just shy of 6" which may be attractive to those with limited room inside their cases.  There is a dial on the back of the PSU which allows you to manually adjust the speed of the fans, allowing for quiet operation if you so choose.  Even at the highest settings this PSU is still much quieter than those PSUs of old cooled by Delta screamers, modern fans are a definite plus in this design.  Check out how this 700W PSU stacks up to the competition in [H]ard|OCP's full review.

NVIDIA Launches Jetson TX2 With Pascal GPU For Embedded Devices

Subject: General Tech, Processors | March 12, 2017 - 05:11 PM |
Tagged: pascal, nvidia, machine learning, iot, Denver, Cortex A57, ai

NVIDIA recently unveiled the Jetson TX2, a credit card sized compute module for embedded devices that has been upgraded quite a bit from its predecessor (the aptly named TX1).

jx10-jetson-tx2-170203.jpg

Measuring 50mm x 87mm, the Jetson TX2 packs quite a bit of processing power and I/O including an SoC with two 64-bit Denver 2 cores with 2MB L2, four ARM Cortex A57 cores with 2MB L2, and a 256-core GPU based on NVIDIA’s Pascal architecture. The TX2 compute module also hosts 8 GB of LPDDR4 (58.3 GB/s) and 32 GB of eMMC storage (SDIO and SATA are also supported). As far as I/O, the Jetson TX2 uses a 400-pin connector to connect the compute module to the development board or final product and the final I/O available to users will depend on the product it is used in. The compute module supports up to the following though:

  • 2 x DSI
  • 2 x DP 1.2 / HDMI 2.0 / eDP 1.4
  • USB 3.0
  • USB 2.0
  • 12 x CSI lanes for up to 6 cameras (2.5 GB/second/lane)
  • PCI-E 2.0:
    • One x4 + one x1 or two x1 + one x2
  • Gigabit Ethernet
  • 802.11ac
  • Bluetooth

 

The Jetson TX2 runs the “Linux for Tegra” operating system. According to NVIDIA the Jetson TX2 can deliver up to twice the performance of the TX1 or up to twice the efficiency at 7.5 watts at the same performance.

The extra horsepower afforded by the faster CPU, updated GPU, and increased memory and memory bandwidth will reportedly enable smart end user devices with faster facial recognition, more accurate speech recognition, and smarter AI and machine learning tasks (e.g. personal assistant, smart street cameras, smarter home automation, et al). Bringing more power locally to these types of internet of things devices is a good thing as less reliance on the cloud potentially means more privacy (unfortunately there is not as much incentive for companies to make this type of product for the mass market but you could use the TX2 to build your own).

Cisco will reportedly use the Jetson TX2 to add facial and speech recognition to its Cisco Spark devices. In addition to the hardware, NVIDIA offers SDKs and tools as part of JetPack 3.0. The JetPack 3.0 toolkit includes Tensor-RT, cuDNN 5.1, VisionWorks 1.6, CUDA 8, and support and drivers for OpenGL 4.5, OpenGL ES 3 2, EGL 1.4, and Vulkan 1.0.

The TX2 will enable better, stronger, and faster (well I don't know about stronger heh) industrial control systems, robotics, home automation, embedded computers and kiosks, smart signage, security systems, and other connected IoT devices (that are for the love of all processing are hardened and secured so they aren't used as part of a botnet!).

Interested developers and makers can pre-order the Jetson TX2 Development Kit for $599 with a ship date for US and Europe of March 14 and other regions “in the coming weeks.” If you just want the compute module sans development board, it will be available later this quarter for $399 (in quantities of 1,000 or more). The previous generation Jetson TX1 Development Kit has also received a slight price cut to $499.

SoftBank Plans To Sell 25% of ARM Holdings To Vision Fund

Subject: General Tech, Processors | March 11, 2017 - 10:02 PM |
Tagged: softbank, investments, business, arm

Japanese telecom powerhouse SoftBank, which recently purchased ARM Holdings for $32 billion USD is reportedly in talks to sell off a 25% stake in its new subsidiary to a new investment fund. Specifically, the New York Times cites a source inside SoftBank familiar with the matter who revealed that SoftBank is in talks with the Vision Fund to purchase a stake in ARM Holdings worth approximately $8 billion USD.

ARM at a glance.png

The $100 billion Vision Fund is an investment fund started by SoftBank founder Masayoshi Son with a goal of investing in high growth technology start-ups and major technology IP holders. The fund is currently comprised of investments from SoftBank worth $25 billion, $45 billion from Saudi Arabia (via Saudi Arabia Public Investment Fund), and minor investments from Apple and Oracle co-founder Lawrence Ellison. The fund is approximately 75% of the way to its $100 billion funding goal with the state owned Mubadala Development investment company in Abu Dhabi and the Qatari government allegedly interested in joining the fund. The Vision Fund is based in the UK and led by SoftBank's Head of Strategic Finance Rajeev Mistra (Investment bankers Nizar al-Bassam and Dalin Ariburnu formerly of Deutsche Bank and Goldman Sachs respectively are also involved.)

It is interesting that SoftBank plans to sell off such a large stake in ARM Holdings so soon after purchasing the company (the sale finalized only six months ago), but it may be a move to entice investors to the investment fund which SoftBank is a part of to further diversify its assets. The more interesting question is the political and regulatory reaction to this news and what it will mean for ARM and its IP to have even more countries controlling it and its direction(s). I do not have the geopolitical acumen to speculate on whether this is a good or bad thing (heh). It does continue the trend of countries outside of the US increasing their investments in established technology companies with lots of IP (wether US based or not) as well as new start ups. New money entering this sector is likely overall good though, at least for the companies involved heh.

I guess we will just have to wait and see if the sale completes and where ARM goes from there! What are your thoughts on the SoftBank sale of a quarter stake in ARM?

MSI's Trident 3 ballistic mini-system

MSI's Trident 3 is much smaller than an Ohio class submarine, measuring roughly the same size as a PS4 Pro, albeit with a very different look.  Inside you will find a Kaby Lake i7-7700, 16GB of DDR4-2400 and a GTX 1060 with storage consisting of a 256GB Kingston M.2 SATA SSD and a 1TB Hitachi Travelstar.  It does lack USB 3.1 and Thunderbolt as the USB Type-C port you see is USB 3.0, it is also worth mentioning the front HDMI port will not function without the included HDMI passthrough connected on the back.  The Tech Report tested it against a similar machine, the Zotac Magnus EN1070 which features a much more powerful mobile GTX 1070.  On the other hand the $1300 Trident 3 comes ready to play, whereas the Zotac lacks a Windows license, storage and memory so even though it sells at $100 less than the MSI system, it may cost you more in the long run.

"MSI's Trident 3 compact PC houses a desktop Core i7-7700 CPU and a GeForce GTX 1060 6GB graphics card in a case no larger than many of today's consoles. We put that tantalizing combo to the test to see whether MSI has achieved small-form-factor gaming nirvana."

Ryzen owners, you can leave your hat on

There are now two less working Ryzen 1700 processors on the planet, sacrificed in an experiment to delid the new AMD products.  The third lived and was tested by der8auer, the mad experimenter, to see what benefits cooling the die directly provide.  The answer is a 2C drop.  This does not seem worth it, considering the high risk, an opinion that Guru 3D shares.  You can of course proceed to do so if you wish, but you might want to buy a half dozen processors to save yourself some time.

"We mentioned in our reviews that you should not delid AMD Ryzen processors for the sheer fact that even the heatspreader has sensors and that it is soldered. Next to that AMD did the cooling part rather well so the benefits of a lower temperatures versus the risk of bricking that processor might not be worth it."
