Google tests switching to a low fibre diet; WiFi almost all the way

The FCC bidding was not terribly exciting but the result was numerous companies buying up parts of the spectrum and more importantly to this post, the opening of 3550-3650 MHz band for anyone to use.  The 3.5GHz band is already allocated to shipborne navigation and military radar systems, this will be a test of ability of computer systems to moderate interference instead of the blanket ban they have always relied on in the past. 

Google is about to test that ability, they will be running a test in several US cities to check the propagation of the signal as well as any possible maritime or military interference from the broadcast.  This could be a way to get high speed internet to the curb without requiring fibre optic runs and would also be compatible with LTE, if Google wanted to dip their toes into that market.  You can read about the tests and where they will be happening over at Hack a Day.


"In a recently released FCC filing, Google has announced their experimental protocol for testing the new CBRS. This isn’t fast Internet to a lamp pole on the corner of the street yet, but it lays the groundwork for how the CBRS will function, and how well it will perform."

3GB Version of NVIDIA GTX 1060 Has 128 Fewer CUDA Cores

Subject: Graphics Cards | August 12, 2016 - 06:33 PM |
Tagged: report, nvidia, gtx 1060 3gb, gtx 1060, GeForce GTX 1060, geforce, cuda cores

NVIDIA will offer a 3GB version of the GTX 1060, and there's more to the story than the obvious fact that is has half the frame buffer of the 6GB version available now. It appears that this is an entirely different product, with 128 fewer CUDA cores (1152) than the 6GB version's 1280.


Image credit:

Boost clocks are the same at 1.7 GHz, and the 3GB version will still operate with a 120W TDP and require a 6-pin power connector. So why not simply name this product differently? It's always possible that this will be an OEM version of the GTX 1060, but in any case expect slightly lower performance than the existing version even if you don't run at high enough resolutions to require the larger 6GB frame buffer.

Wherein the RX 470 teaches us a valuable lesson about deferred procedure calls

Subject: Graphics Cards | August 12, 2016 - 05:44 PM |
Tagged: rx 470, LatencyMon, dpc, amd

When The Tech Report first conducted their review of the RX 470 they saw benchmark behaviour very different from any other GPU in that family but could not figure out what it was and resolve it before the mob arrived with pitchforks and torches demanding they publish or die. 

As it turns out there was indeed something rotten in benchmark; incredibly high DPC on the test machine.  Investigation determined the culprit to be the beta BIOS on their ASRock Z170 Extreme7+, specifically the BIOS which allowed you to overclock locked Intel CPUs.  They have just released their new findings along with a look at LatencyMon and DPC in general.  Take a look at the new benchmarks and information about DPC, but also absorb the consequences of demanding articles arrive picoseconds after the NDA expires; if there is a delay in publishing there might just be a damn good reason why.


"We retested our RX 470 to account for this issue, and we also updated our review with DirectX 12 benchmarks for Rise of the Tomb Raider and Hitman, plus full OpenGL and Vulkan benchmarks for Doom."

A mouthfull of a motherboard, the MSI X99A XPower Gaming Titanium Edition

Subject: Motherboards | August 12, 2016 - 03:26 PM |
Tagged: X99A XPower Gaming Titanium Edition, Intel X99, msi

The list of features on this motherboard is as long as the name; five PCIe 3.0 16x slots, the  Game Boost overclocking knob, 10 SATA 6Gbps ports, one each of SEx, M.2 and U.2, 13 USB 3.1 ports including a single Type C, WiFi and Bluetooth ... all it is missing is a game fowl in a fruit tree.  [H]ard|OCP did have problems with XMP settings, but nothing they couldn't overcome via manual settings and the issues they had with the Core-i7 6950X turned out to be caused by the PSU and RAM and not the motherboard at all.  If you need a plethora of storage and add-in cards then check this board out as it can handle almost anything you want to stick in it.


"MSI’s X99A XPOWER GAMING TITANIUM is a mouthful, but the XPOWER series has been a favorite of ours here at HardOCP for years now. The latest X99 iteration has much to prove. Is the X99A XPOWER GAMING TITANIUM another pretty face, or is it a fitting addition to the venerable XPOWER line?"

Xaggerated claims from Intel? Psah, we've heard that googolplex of times before

You might have caught our reference to this on the podcast, XPoint is amazingly fast but the marketing clams were an order or magnitude or two off of the real performance levels.  Al took some very nice pictures at FMS and covered what Micron had to say about their new QuantX drives.  The Register also dropped by and offers a tidbit on the pricing, roughly four to five times as much as current flash or about half the cost of an equivalent amount of RAM.  They also compare the stated endurance of 25 complete drive writes per day to existing flash which offers between 10 to 17 depending on the technology used. 

The question they ask at the end is one many data centre managers will also be asking, is the actual speed boost worth the cost of upgrading or will other less expensive alternatives be more economical?


"XPoint will substantially undershoot the 1,000-times-faster and 1,000-times-longer-lived-than-flash claims made by Intel when it was first announced – with just a 10-times speed boost and 2.5-times longer endurance in reality."

Corsair Releases Hydro GFX GTX 1080 Liquid-Cooled Graphics Card

Subject: Graphics Cards | August 12, 2016 - 10:59 AM |
Tagged: overclock, nvidia, msi, liquid cooled, hydro H55, hydro gfx, GTX 1080, graphics card, gaming, corsair

Corsair and MSI have teamed up once again to produce a liquid-cooled edition of the latest NVIDIA GPU, with the GTX 1080 receiving the same treatment these two gave to the Hydro GFX version of GTX 980 Ti last year.


“The CORSAIR Hydro GFX GTX 1080 brings all the benefits of liquid cooling to the GeForce GTX 1080, boasting an integrated CORSAIR Hydro Series H55 cooler that draws heat from the GPU via a micro-fin copper base cold plate and dissipates it efficiently using a 120mm high-surface area radiator. A pre-installed low-noise LED-lit 120mm fan ensures steady, reliable air-flow, keeping GPU temperatures down and clock speeds high.

With a low-profile PCB and pre-fitted, fully-sealed liquid cooler, the Hydro GFX GTX 1080 is simple and easy to install. Just fit the card into a PCI-E 3.0 x16 slot, mount the radiator and enjoy low maintenance liquid cooling for the lifetime of the card.”

Naturally, with an integrated closed-loop liquid cooler this GTX 1080 won't be relegated to stock speeds out of the box, though Corsair leaves this up to the user. The card offers three performance modes which allow users to choose between lower noise and higher performance. Silent Mode leaves the GTX 1080 at stock settings (1733 MHz Boost), Gaming Mode increases the Boost clock to 1822 MHz, and OC Mode increases this slightly to 1847 MHz (while increasing memory speed in this mode as well).


This liquid-cooled version will provide higher sustained clocks

Here are the full specs from Corsair:

  • GPU: NVIDIA GeForce GTX 1080
  • CUDA Cores: 2,560
  • Interface: PCI Express 3.0 x16

Microsoft Won't End Support for Skylake on Windows 7/8.1

Subject: General Tech | August 11, 2016 - 05:42 PM |
Tagged: windows 10, microsoft

Previously, Microsoft said that they will end support for Skylake-based processors on Windows 7 and Windows 8.1 before the OS's extended support date. Later processors, like Intel's Kaby Lake and AMD's Bristol Ridge, will not be supported on 7 and 8.1 at all. To use those processors, their associated devices will need to be running Windows 10 (or, you know, Linux or something).


This has just changed for Skylake, but not for Kaby Lake and Bristol Ridge. Skylake will now be supported through the entire life-cycle of Windows 7 (January 14, 2020) and Windows 8.1 (January 10, 2023). This is particularly good because Skylake was already released and in the hands of users when they first announced pulling the plug. Now users will know before they purchase their hardware (albeit not before many have purchased a retail copy of Windows 7 or Windows 8.x with transfer rights that intend to continually upgrade beyond Skylake or to AMD's Zen architecture) that Microsoft will not support it outside of Windows 10.

Arctic has a rather unique product up for sale, an analog gaming headset modelled after the style you would see a helicopter pilot on TV wearing.  The P533 Military Stereo Headset utilizes the standard 40mm neodymium drivers common to many headsets with a dynamic range of 20Hz-20KHz, 32Ohm impedance and 95dB sensitivity.  The microphone boom is longer than usual and features several joints to allow you to position it exactly where you want.  The P533 also has an integrated volume control knob on the outside of the right ear cup as opposed to inline on the cord, which ends in 3.5mm jacks.  There is no doubt that the hard, rounded cups are unique looking although perhaps not what most of us are looking for.  Check out Nikktech's review of the P533, even if it is just to see the design of these things.

Backdoors are bad Microsoft; hadn't this become very obvious already?

Tagged: Secure Boot, microsoft, backdoor, security

Yes, even though this occurs on a regular occasion, we are to be shocked that another secret backdoor into a security product has been discovered, exploited and published.  In this case it is Microsoft's Secure Boot which has been unlocked and even better news is that it probably cannot be completely repaired without rendering previous backups and installations incompatible.  On the positive side, devices which are locked down even for those with administrative privileges such as ARM-based Windows RT tablets can be unlocked and you can chose a different OS to install.  The negatives will have more of an effect on businesses and system builders who relied on it to prevent modified Windows installs from booting, preventing infections and questionably sourced Windows images from being used. 

The Register has links to more information on Secure Boot and Microsoft's response and you can read some information about the group which found and released the information about this over at The Inquirer.

FMS 2016: Phison E8 Controller - NVMe Speed at SATA Cost

Tagged: ssd, PS5008-E8/E8T, PS5008-E8, PS5007-E7, phison, PCIe 3.0 x2, NVMe, FMS 2016, FMS, E8

I visited Phison to check out their new E8 controller:


Phsion opted to take a step back from the higher performance PCIe 3.0 x4 NVMe controllers out there, offering a solution with half the lanes. PCIe 3.0 x2 can still handle 1.5 GB/s, and this controller can exceed 200,000 random IOPS. Those specs are actually in-line with what most shipping x4 solutions offer today, meaning the E8 is more effectively saturating its more limited connectivity. Reducing the number of lanes helps Phison reduce the component cost of this controller to match the cost of typical SATA controllers while tripling the performance, greatly reducing the cost to produce NVMe SSDs.

In addition to 3D Flash support, the E8 is also a DRAM-less controller, meaning it has a small internal SRAM cache and has been architected to not need external DRAM installed on the PCB. DRAM-less means even lower costs. This can only be a good thing, since high performing NVMe parts at SATA costs is going to drive down the costs of even faster NVMe solutions, which is great for future buyers.

Press blast after the break.

FMS 2016: Micron QuantX XPoint Prototype SSD Spotted

Subject: Storage | August 11, 2016 - 12:06 PM |
Tagged: FMS, FMS 2016, XPoint, micron, QuantX, nand, ram

Earlier this week, Micron launched their QuantX branding for XPoint devices, as well as giving us some good detail on expected IOPS performance of solutions containing these new parts:


Thanks to the very low latency of XPoint, the QuantX solution sees very high IOPS performance at a very low queue depth, and the random performance very quickly scales to fully saturate PCIe 3.0 x4 with only four queued commands. Micron's own 9100 MAX SSD (reviewed here), requires QD=256 (64x increase) just to come close to this level of performance! At that same presentation, a PCIe 3.0 x8 QuantX device was able to double that throughput at QD=8, but what are these things going to look like?


The real answer is just like modern day SSDs, but for the time being, we have the prototype unit pictured above. This is essentially an FPGA development board that Micron is using to prototype potential controller designs. Dedicated ASICs based on the final designs may be faster, but those take a while to ramp up volume production.


So there it is, in the flesh, nicely packaged and installed on a complete SSD. Sure it's a prototype, but Intel has promised we will see XPoint before the end of the year, and I'm excited to see this NAND-to-DRAM performance-gap-filling tech come to the masses!


FMS 2016: Liqid Combines Quad M.2 in to Powerful Packages

Subject: Storage | August 11, 2016 - 11:18 AM |
Tagged: FMS, FMS 2016, Liqid, kingston, toshiba, phison, U.2, HHHL, NVMe, ssd

A relative newcomer this year at Flash Memory Summit was Liqid. These guys are essentially creating an ecosystem from a subset of parts. Let's start with Toshiba:


At Toshiba's booth, we spotted their XG3 being promoted as being part of the Liqid solution. We also saw a similar demo at the Phison booth, meaning any M.2 parts can be included as part of their design. Now let us get a closer look at the full package options and what they do:


This demo, at the Kingston booth, showed a single U.2 device cranking out 835,000 4k IOPS. This is essentially saturating its PCIe 3.0 x4 link with random IO's, and it actually beats the Micron 9100 that we just reviewed!


How can it pull this off? The trick is that there are actually four M.2 SSDs in that package, along with a PLX switch. The RAID must be handled on the host side, but so long as you have software that can talk to multiple drives, you'll get full speed from this part.

More throughput can be had by switching to a PCIe 3.0 x8 link on a HHHL form factor card:


That's 1.3 million IOPS from a single HHHL device! Technically this is four SSDs, but still, that's impressively fast and is again saturating the bus, but this time it's PCIe 3.0 x8 being pegged!


We'll be tracking Liqid's progress over the coming months, and we will definitely test these solutions as they come to market (we're not there just yet). More to follow from FMS 2016!

Supermicro was at FMS 2016, showing off some of their NVMe chassis:


The first model is the SYS-1028U-TN10RT+. This 1U chassis lets you hot swap 10 2.5" U.2 SSDs, connecting all lanes directly to the host CPUs.


Supermicro's custom PCB and interposer links all 40 PCIe lanes to the motherboard / CPUs.


Need more drives installed? Next up is the SYS-2028U-TN24R4T+, which uses a pair of PCIe switches to connect 24 U.2 SSDs to the same pair of CPUs.


Need EVEN MORE drives installed? The SSG-2028R-NR48N uses multiple switches to connect 48 U.2 SSDs in a single 2U chassis! While the switches will limit the ultimate sequential throughput of the whole package to PCIe 3.0 x40, we know that when it comes to spreading workloads across multiple SSDs, bandwidth bottlenecks are not the whole story, as latency is greatly reduced for a given workload. With a fast set of U.2 parts installed in this chassis, the raw IOPS performance would likely saturate all threads / cores of the installed Xeons before it saturated the PCIe bus!

ASUS Adds Radeon RX 470 and RX 460 to ROG STRIX Gaming Lineup

Ryan posted details about the Radeon RX 470 and 460 graphics cards at the end of last month, and both are now available. Now the largest of the board partners, ASUS, has added both of these new GPUs to their Republic of Gamers STRIX series.


The STRIX Gaming RX 470 (Image: ASUS)

ASUS announced the Radeon RX 470 STRIX Gaming cards last week, and today the more affordable RX 460 GPU variant has been announced. The RX 470 is certainly a capable gaming option as it's a slightly cut-down version of the RX 480 GPU, and with the two versions of the STRIX Gaming cards offering varying levels of overclocking, they can come even closer to the performance of a stock RX 480.


The STRIX Gaming RX 460 (Image: ASUS)

The new STRIX Gaming RX 460 is significantly slower, with just 896 stream processors (to the 2048 of the RX 470) and a 128-bit memory interface (compared to 256-bit). Part of the appeal of the reference RX 460 - aside from low cost - is low power draw, as the <75W power draw allows for slot-powered board designs. This STRIX Gaming version adds a 6-pin power connector, however, which should provide additional overhead for further overclocking.

The STRIX Gaming RX 470 OC 4GB is priced at $199, matching the (theoretical) retail of the 4GB RX 480, and the STRIX Gaming RX 470 is just behind at $189. The considerably lower-end STRIX Gaming RX 460 is $139. A check of Amazon/Newegg shows listings for these cards, but no in-stock units as of early this afternoon.

AMD Releases Radeon Software Crimson Edition 16.8.1

Subject: Graphics Cards | August 10, 2016 - 04:59 PM |
Tagged: amd, graphics drivers

Alongside the release of the Radeon RX 460 and RX 470 graphics cards, AMD has released the Radeon Software Crimson Edition 16.8.1 drivers. Beyond adding support for these new products, it also adds a Crossfire profile for F1 2016 and fixes a few issues, like Firefox and Overwatch crashing under certain circumstances. It also allows users of the RX 480 to overclock their memory higher than they previously could.


AMD is continuing their trend of steadily releasing graphics drivers, and rapidly fixing important issues as they arise. Also, they have been verbose in their release notes, outlining fixes and known problems as they occur. Users can often track the bugs that affect them as they are added to the Known Issues, then graduated to Fixed Issues. While this often goes unrecognized, it's frustrating as a user to experience a bug and not know whether the company even knows about it, or they are just refusing to acknowledge it.

Useful release notes, like AMD has been publishing, are very helpful in that regard.

When [H]ard|OCP looks at the performance of a VR game, be it a Vive or Rift title, they focus on the gameplay experience as opposed to benchmarks.  There are numerous reasons for this, from the fact that these games do not tend to stress GPUs like many triple A titles but also because the targets are different, steady render times below 11.1ms are the target as opposed to higher frame counts.  AMD initially had issues with this game, the newest driver release has resolved those issues completely.  The takeaway quote in [H]'s conclusions provide the most telling part of the review, "If we were to perform a blind gaming test, you would not be able to identify which GPU you were gaming with at the time."


"We are back this week to take another objective look at AMD and NVIDIA GPU performance in one of the the top selling games in the VR-only realm, The Gallery Episode 1: Call of Starseed. This is another GPU-intensive title that has the ability to put some GPUs on their heels. How do the new RX 480 and GeForce 1000 series perform?"

At a huge press event like Flash Memory Summit, being in the right place at the right time (and with the right camera), matters greatly. I'll just let a picture say a thousand words for me here:

64-Layer V-NAND.jpg this picture has been corrected for extreme parallax and was taken in far from ideal conditions, but you get the point. Samsung's keynote is coming up later today, and I have a hunch this will be a big part of what they present. We did know 64-Layer was coming, as it was mentioned in Samsung's last earnings announcement, but confirmation is nice.

*edit* now that the press conference has taken place, here are a few relevant slides:



With 48-Layer V-NAND announced last year (and still rolling out), it's good to see Samsung pushing hard into higher capacity dies. 64-Layer enables 512Gbits (64GB) per die, and 100MB/s per die maximum throughput means even lower capacity SSDs should offer impressive sequentials.

64-Layer is Samsung's 4th generation of V-NAND. We've seen 48-Layer and 32-Layer, but few know that 24-Layer was a thing (but was mainly in limited enterprise parts).

We will know more shortly, but for now, dream of even higher capacity SSDs :)

*edit* and this just happened:

*additional edit* - here's a better picture taken after the keynote:



The 32TB model in their 2.5" form factor displaces last years 16TB model. The drive itself is essentially identical, but the flash packages now contain 64-layer dies, doubling the available capacity of the device.

FMS 2016: Seagate Demos Facebook Lightning, 60TB 3.5" SSD!

Subject: Storage | August 10, 2016 - 01:59 PM |
Tagged: FMS 2016, ssd, Seagate, Lightning, facebook, 60TB

Seagate showed off some impressive Solid State Storage at Flash Memory Summit 2016.


First up is the Nytro XM1440. This is a 2TB M.2 22110 SSD complete with enterprise firmware and power loss protection. Nice little package, but what's it for?


..well if you have 60 of them, you can put them into this impressive 1U chassis. This is Facebook's Lightning chassis (discussed yesterday). With Seagate's 2TB parts, this makes for 120TB of flash in a 1U footprint. Great for hyperscale datacenters.

Now onto what you came to see:


This is the 'Seagate 60TB SAS SSD'. It really doesn't need a unique name because that capacity takes care of that for us! This is a 3.5" form factor SAS 12Gbit beast of a drive.



They pulled this density off with a few tricks which I'll walk through. First was the stacking of three PCBs with flash packages on both sides. 80 packages in total.


Next up is Seagate's ONFi fan-out ASIC. This is required because you can only have so many devices connected to a single channel / bus of a given SSD controller. The ASIC acts as a switch for data between the controller and flash dies.


With so much flash present, we could use a bit of fault tolerance. You may recall RAISE from SandForce (who Seagate now owns). This is effectively RAID for flash dies, enabling greater resistance to individual errors across the array.


Finally we have the specs. With a dual 12 Gbit SAS inteface, the 60TB SAS SSD can handle 1.5 GB/s reads, 1.0 GB/s writes, and offers 150,000 IOPS at 4KB QD32 random (SAS tops out at QD32). The idea behind drives like these is to cram as much storage into the smallest space possible, and this is certainly a step in the right direction.


We also saw the XP7200 add-in card. I found this one interesting as it is a PCIe 3.0 x16 card with four M.2 PCIe 3.0 x4 SSDs installed, but *without* a PLX switch to link them to the host system. This is possible only in server systems supporting PCIe Bifurcation, where the host can recognize that certain sets of lanes are linked to individual components.
