Qualcomm has officially launched the Snapdragon 821 SoC, an upgraded successor to the existing Snapdragon 820 found in such phones as the Samsung Galaxy S7.
"With Snapdragon 820 already powering many of the premier flagship Android smartphones today, Snapdragon 821 is now poised to become the processor of choice for leading smartphones and devices for this year’s holiday season. Qualcomm Technologies’ engineers have improved Snapdragon 821 in three key areas to ensure Snapdragon 821 maintains the level of industry leadership introduced by its predecessor."
Specifications were previously revealed when the Snapdragon 821 was announced in July, with a 10% increase on the CPU clocks (2.4 GHz, up from the previous 2.2 GHz max frequency). The Adreno 530 GPU clock increases 5%, to 650 MHz from 624 MHz. In addition to improved performance from CPU and GPU clock speed increases, the SD821 is said to offer lower power consumption (estimated at 5% compared to the SD820), and offers new functionality including improved auto-focus capability.
Enhanced overall user experience:
The Snapdragon 821 has been specifically tuned to support a more responsive user experience when compared with the 820, including:
- Shorter boot times: Snapdragon 821 powered devices can boot up to 10 percent faster.
- Faster application launch times: Snapdragon 821 can reduce app load times by up to 10 percent.
- Smoother, more responsive user interactions: UI optimizations and performance enhancements designed to allow users to enjoy smoother scrolling and more responsive browsing performance.
Improved performance and power consumption:
- CPU speeds increase: As we previously announced, the 821 features Qualcomm Kryo CPU speeds up to 2.4GHz, representing an up to 10 percent improvement in performance over Snapdragon 820.
- GPU speeds increase: The Qualcomm Adreno GPU received a 5 percent speed increase over Snapdragon 820.
- Power savings: The 821 is engineered to deliver an incremental 5 percent power savings when comparing standard use case models. This power savings can extend battery life and support OEMs interested in reducing battery size for slimmer phones.
New features and functionality:
- Snapdragon 821 introduces several new features and capabilities, offering OEMs new options to create more immersive and engaging user experiences, including support for:
- Snapdragon VR SDK (Software Development Kit): Offers developers a superior mobile VR toolset, provides compatibility with the Google Daydream platform, and access to Snapdragon 821’s powerful heterogeneous architecture. Snapdragon VR SDK supports a superior level of visual and audio quality and more immersive virtual reality and gaming experiences in a mobile environment.
- Dual PD (PDAF): Offers significantly faster image autofocus speeds under a wide variety of conditions when compared to single PDAF solutions.
- Extended Laser Auto-Focus Ranging: Extends the visible focusing range, improving laser focal accuracy over Snapdragon 820.
- Android Nougat OS: Snapdragon 821 (as well as the 820) will support the latest Android operating system when available, offering new features, expanded compatibility, and additional security compared to prior Android versions.
Qualcomm says the ASUS ZenFone 3 Deluxe is the first phone to use this new Snapdragon 821 SoC while other OEMs will be working on designs implementing the upgraded SoC.

Tagged: cooler master, MasterMouse Pro L, ambidextrous
Rejoice computer users as you will no longer be a slave to chirality thanks to your new rodent overlord, Cooler Master's MasterMouse Pro L! This mouse is properly ambidextrous, both sides of the mouse have the same buttons and fancy RGB lighting and the DPI button is equally inconvenient for everyone as it is located on the bottom of the mouse. For hardware it uses a Avago PMW-3360 IR optical sensor which can be set up to a sensitivity of 12,000 DPI. The mouse also comes with two swapable shells for the top of the mouse and CM plans on releasing the specifications so you can print your own if you so desire.
"Today, we are taking a look at the Cooler Master ‘MasterMouse Pro L’, a true ambidextrous mouse with modular covers for the body and side grips, allowing users to make physical changes to the mouse to better suit them."

Tagged: nvidia, GeForce 372.70, driver
NVIDIA continues with their Game Ready driver program, releasing the GeForce 372.70 driver, hand crafted in the new world by artisanal engineers to bring enhanced support to World of Warcraft: Legion, Battlefield 1: Open Beta, Deus Ex: Mankind Divided, and Quantum Break. There is not much to see in the release notes, although you can now enjoy Deus Ex in glorious 3D vision assuming you have the monitor and glasses.
If you are testing the new Battlefield you should consider updating, one would suppose the bug reports submitted using this driver will be more beneficial to the developers than an older release. You know the drill, grab them from GeForce.com or NVIDIA.com.

Tagged: ssd, laptop, ultraportable
The increasing use of on-board memory by OEMs in ultraportables has some enthusiasts unhappy, however the trend that DigiTimes mentioned today should cheer them up somewhat. It is predicted by DRAMeXchange that over half of all laptops will use an SSD for storage by 2018. There are some rather interesting bits of data in the post, for instance the pricing of SSDs for OEMs have reportedly stabilized for the first time, with a quoted rise in prices of 0-0.5% for MLC and 0-1% TLC based models compared with the prior quarter. These numbers seem in direct opposition to the retail market where not only have we seen a steady decline in SSD prices, the change has been much greater than 1%.
There is a shadow cast by this silver lined cloud; with more demand by OEMs for NAND there will be more pressure on manufacturers and so it is predicted that supply will be unable to meet demand in Q3 of this year. One would expect manufacturers to produce for the market segment that offers a greater profit margin and if the pricing mentioned previously is accurate, that is not retail. It will be interesting to see what, if anything, happens to SSD pricing in the fall.
"DRAMeXchange has maintained its estimate given earlier in 2016 that the adoption of SSDs in notebooks would exceed 30% in 2016. The proportion is forecast to reach 56% in 2018, according to the research firm."

Tagged: microSD, Samsung, evo plus, U3, UHS-I
A while back Al broke down the specifications of SD cards and what each class meant and the proper usage for them. The top class is U3 and it offers transfer speeds high enough to support recording 4K video on your devices and that happens to be the rating on the new 256GB Samsung EVO Plus MicroSD. Legion Hardware just tested this MicroSD card and it now holds the title of best performing SD card they have tested. The performance does come at a premium, the MSRP of the card is $250 and even with a 10 year warranty this is still an expensive purchase. If you need the ability to record 4K video immediately this is the fast solution available but if you are still in the planning stages, remember that there is a new standard, UFS, which is due to hit the market soon and impact pricing of older products.
"Running out of storage on your smartphone, tablet or 4K video camera? Well the good news is SD cards have never been more affordable and crucially offered such huge storage capacities. In fact, Samsung recently announced the availability of a 256GB version of their popular EVO Plus MicroSD card series"

The Register had a quick chat with Samsung about the Z-SSD they announced at FMS 2016, hoping to get some details from the company about the technology behind the new product, with little success. We know it will be DRAM-NAND gap-filler such as the one Netlist announced earlier and will be possible competition for Intel's XPoint. Samsung did confirm that it will be NVMe and will initially launch as a half height, half length PCIe card, with other interfaces to follow. They did admit it will use 3D V-NAND, but would only hint at the custom circuit design they will use. The Register offers some prognostication at the end of the quick interview, you can see that right here.
"The mysterious Samsung Z-SSD was announced at the Flash Memory Summit, and positioned as a DRAM-NAND gap-filler. This makes it competition for XPoint. We asked Samsung about it, and here is what we learnt."

ASUS has officially announced their latest workstation board for the Intel X99 platform, and the X99-E-10G WS offers a 10GbE NIC. In fact, it has two of the Intel X550-powered 10 Gigabit Ethernet ports onboard (along with many more premium features).
ASUS lists these key features:
- First workstation board with dual Intel® 10G LANs (X550-AT2) on board
- 4-Way PCI-E Gen3 x16 link supporting NVidia GeForce SLI® and AMD CrossFireX™ on demand
- 5-Way Optimization by Dual Intelligent Processors 5 – One click, total system optimization
- Ultimate transfer speed : the latest 10Gb/s USB 3.1 type-A and type-C, 32Gbit/s M.2 and U.2
- SafeSlot : reinvented, strengthened PCIe slot utilizes a new insert-molding process for superior retention and shearing resistance
The full list of specifications is daunting, as ASUS has packed just about every imaginable option into this board. Processor support also extends beyond Core i7 processors to include Intel Xeon E5-1600 v3, E5-2600 v3, E5-1600 v4, and E5-2600 v4 series CPUs. (Naturally, ECC memory is supported when using a compatible CPU.)
We await info on pricing and availablity.

Tagged: pcie, PCI SIG
Last week, various outlets were reporting (incorrectly) that PCIe 4.0 would provide “at least 300W” through the slot. This would have been roughly equal to the power draw that a PCIe 3.0 GPU could provide with an extra six-pin and an extra eight-pin power connector, but do so all through the slot.
Later, the PCI-SIG contacted Tom's Hardware (and likely others) to say that this is not the case. The slot will still only provide 75W of power; any other power will still need to come from external connectors. The main advantage of the standard will be extra bandwidth, about double that of PCIe 3.0, not easing cable management or making it easier to design a graphics card (by making it harder to design a motherboard).

Tagged: wheel base, Thrustmaster, T500RS, T300, steering wheel, pedals, Fanatec, CSL Elite, ClubSport V2
This past Summer I was introduced to Fanatec products for the first time. Before that I had only handled some lower end Genius products, as well as low end and midrange Thrustmaster units. My review of the Fanatec setup will be posted here this next week, but my overall impressions of what Fanatec offers is overwhelmingly positive. The only issue, and it is a glaring one, is the lack of an affordable setup based on their designs. This past Friday Fanatec introduced a new series of products that aims to make their setups far more affordable than what we have seen so far.
The new CSL Elite Series of products offer many of the same features of the higher end ClubSport series of products, but at a much more affordable price range. This does not mean that they are skimping out on features and quality construction. The CSL Elite Pedals with Loadcell Kit offer a full aluminum build with a three pedal setup and the load cell on the brake pedal. This allows increasing resistance during braking that other spring loaded pedals may not offer. Fanatec claims that up to 90kg of pressure can be applied to the load cell. Having used their upper end ClubSport pedals, I can attest to what a difference such a load cell and a heavy aluminum base can do for the racing experience. Fanatec includes three different types of anti-skid pads that can be swapped out on the pedals.
The CSL Elite Wheel Base offers 6NM of force to the wheel. This is more than the ClubSport V1 base, but slightly less than the V2. In violent crashes, the wheel certainly can break the grip of the user’s hands. The base accepts a wide variety of wheels from Fanatec, but the bundle comes with the CSL Steering Wheel P1 for Xbox One. The base comes with the automotive grade quick release unit that easily swaps in and out wheels. The base also includes an RPM LED display on the base that is not included in the ClubSport series. The base also includes a built-in table clamp that is a $50 accessory for the ClubSport V2 setup.
The smaller motor, single belt design, and plastic construction of the wheel base allows Fanatec to shave a big portion of the price off of this part. It still features the metal drive shaft and metal quick release mechanism (something that Thrustmaster doesn’t have even on their high end T500RS base). The base still allows the connections for the optional shifter and e-brake.
Fanatec offers the bundle with a full version of Assetto Corsa for Xbox One for $639.85. This is a tremendous price point that puts it in range of the T500RS. Fanatec products have never been this reasonable for PC and Xbox One racers. It is still a chunk of change, but it is nowhere near the $1800 range where a full ClubSport V2 setup can be bought for.
The base can be upgraded with options such as a static paddle shifters.
I’m looking forward to seeing reviews of these parts and how they stack up to the V2 and other setups from competitors.

Tagged: blizzard, facebook, OBS
So I was greeted with an interesting pop-up when I updated my Battle.net launcher today. Turns out Blizzard is pushing Blizzard Streaming to “the Americas, Southeast Asia, Australia, and New Zealand”. Currently, Facebook is the only platform that you can stream to, and Blizzard hasn't announced bringing it to others, but the settings area is clearly a vertical list of horizontal widgets, so that suggests they intend to add more than one at some point.
As for the application, itself, this could be useful (especially if other services are added) for users who only stream Blizzard titles, and who want something designed a bit more mainstream than OBS. That said, Raptr and GeForce Experience both fall under this category. Moreover, Blizzard doesn't clarify whether or not the stream will make use of NVIDIA's NVENC, Intel's Quick Sync, or AMD's VCE, all three of which are supported on OBS Studio. Granted, Blizzard titles tend to be easy to compute, but it is hard to beat encoding on an idle, integrated GPU, if you should have one.
That said, choices are good, and you now have another.

The Thermaltake Core P100 is something new to the market, except perhaps for the Cooler Master HAF Stacker 935 case components. It adds additional space to Thermaltake's W100 chassis and is aptly named as the P100 is placed underneath the W100. You will need to assemble it as it ships in pieces, just as the W100 does so expect to put some work into setting up these cases. Once assembled it measures 9.8x12.2x26.7" and gives you space to add additional radiators to your system, you could place the PSU in there and still fit in some smaller radiators or perhaps even fill it with drives. Drop by [H]ard|OCP to see some of the possiblities, including a complete mini-ITX build.
"The Thermaltake Core P100 Pedestal is an expansion part for the Thermaltake W100 full tower case previously reviewed here. What the P100 does is give you the ability to expand you cooling system's ability or give you space for extra storage among other things into an entirely self-contained unit below the W100 chassis."

The Inquirer offered some sad news for anyone hoping to see GDDR6 next year as Samsung is now aiming to deliver in 2018. The specifications remain the same, internal bandwidth topping out at 16Gbps, compared to GDDR5X at 12Gbps. That will translate to a maximum of 512GBps on a 256-bit memory bus, 786GBps on a 384-bit bus. Mobile devices will also appreciate the new standard as it should use around 20% less power, good news for those who buy gaming laptops.

Intel announced the production of 3D NAND a little over a year ago, and we've now seen production ramp up to the point where they are infusing it into nearly every nook and cranny of their SSD product lines.
The most relevant part for our readers will be a long overdue M.2 2280 SSD. These will kick off with the 600p:
An overseas forum member over at chiphell got their hands on a 600p and ran some quick tests. From their photo (above), we can confirm the controller is not from Intel, but rather from Silicon Motion. The NAND is naturally from Intel, as is likely their controller firmware implementation, as these parts go through the same lengthy validation process as their other products.
Intel is going for the budget consumer play here. The flash will be running in TLC mode, likely with an SLC cache. Specs are respectable - 1.8GB/s reads, 560MB/s writes, random read 155k, random write 128k (4KB QD=32). By respectable specs I mean in light of the pricing:
Wow! These prices are ranging from $0.55/GB at 128GB all the way down to $0.35/GB for the 1TB part.
Intel also refreshed their DataCenter (DC) lineup. The SSD DC S3520 (SATA) and P3520 (PCIe/NVMe) were also introduced as a refresh, also using Intel's 3D NAND. We published our exclusive review of the Intel SSD DC P3520 earlier today, so check there for full details on that enterprise front. Before we move on, a brief moment of silence for the P3320 - soft-launched in April, but discontinued before it shipped. We hardly knew ye.
Lastly, Intel introduced a few additional products meant for the embedded / IoT sector. The SSD E 6000p is an M.2 PCIe part similar to the first pair of products mentioned in this article, while the SSD E 5420s comes in 2.5" and M.2 SATA flavors. The differentiator on these 'E' parts is enhanced AES 256 crypto.
Most of these products will be available 'next week', but the 600p 360GB (to be added) and 1TB capacities will ship in Q4.
Abbreviated press blast appears after the break.

Multi-In Multi-Out routers are a wonderful thing, not only are the routers far more tentacular than before, the technology also make our unwired lives better as Sebastian explained. The only thing that could make it better is a bandwidth boost, which is what these researchers at MIT have been working on. In an experiment involving laptop bearing Roombas they showed a increase of 330% in transfer speeds thanks to synchronized phases allowing multiple signals to be sent on the same frequency. Pop on over to Slashdot to learn more about their research.

Hardware/Software Picks of the Week

Tagged: TSV, SK Hynix, Samsung, hot chips, hbm3, hbm
Samsung and SK Hynix were in attendance at the Hot Chips Symposium in Cupertino, California to (among other things) talk about the future of High Bandwidth Memory (HBM). In fact, the companies are working on two new HBM products: HBM3 and an as-yet-unbranded "low cost HBM." HBM3 will replace HBM2 at the high end and is aimed at the HPC and "prosumer" markets while the low cost HBM technology lowers the barrier to entry and is intended to be used in mainstream consumer products.
As currently planned, HBM3 (Samsung refers to its implementation as Extreme HBM) features double the density per layer and at least double the bandwidth of the current HBM2 (which so far is only used in NVIDIA's planned Tesla P100). Specifically, the new memory technology offers up 16Gb (~2GB) per layer and as many as eight (or more) layers can be stacked together using TSVs into a single chip. So far we have seen GPUs use four HBM chips on a single package, and if that holds true with HBM3 and interposer size limits, we may well see future graphics cards with 64GB of memory! Considering the HBM2-based Tesla will have 16 and AMD's HBM-based Fury X cards had 4GB, HBM3 is a sizable jump!
Capacity is not the only benefit though. HBM3 doubles the bandwidth versus HBM2 with 512GB/s (or more) of peak bandwidth per stack! In the theoretical example of a graphics card with 64GB of HBM3 (four stacks), that would be in the range of 2 TB/s of theoretical maximum peak bandwidth! Real world may be less, but still that is many terabytes per second of bandwidth which is exciting because it opens a lot of possibilities for gaming especially as developers push graphics further towards photo realism and resolutions keep increasing. HBM3 should be plenty for awhile as far as keeping the GPU fed with data on the consumer and gaming side of things though I'm sure the HPC market will still crave more bandwidth.
Samsung further claims that HBM3 will operate at similar (~500MHz) clocks to HBM2, but will use "much less" core voltage (HBM2 is 1.2V).
Stacked HBM memory on an interposer surrounding a processor. Upcoming HBM technologies will allow memory stacks with double the number of layers.
HBM3 is perhaps the most interesting technologically; however, the "low cost HBM" is exciting in that it will enable HBM to be used in the systems and graphics cards most people purchase. There were less details available on this new lower cost variant, but Samsung did share a few specifics. The low cost HBM will offer up to 200GB/s per stack of peak bandwidth while being much cheaper to produce than current HBM2. In order to reduce the cost of production, their is no buffer die or ECC support and the number of Through Silicon Vias (TSV) connections have been reduced. In order to compensate for the lower number of TSVs, the pin speed has been increased to 3Gbps (versus 2Gbps on HBM2). Interestingly, Samsung would like for low cost HBM to support traditional silicon as well as potentially cheaper organic interposers. According to NVIDIA, TSV formation is the most expensive part of interposer fabrication, so making reductions there (and somewhat making up for it in increased per-connection speeds) makes sense when it comes to a cost-conscious product. It is unclear whether organic interposers will win out here, but it is nice to seem them get a mention and is an alternative worth looking into.
Both high bandwidth and low latency memory technologies are still years away and the designs are subject to change, but so far they are both plans are looking rather promising. I am intrigued by the possibilities and hope to see new products take advantage of the increased performance (and in the latter case lower cost). On the graphics front, HBM3 is way too far out to see a Vega release, but it may come just in time for AMD to incorporate it into its high end Navi GPUs, and by 2020 the battle between GDDR and HBM in the mainstream should be heating up.
What are your thoughts on the proposed HBM technologies?

Do you recall the new long playing version of the SFX PSU form factor; specifically Lee's review of the SilverStone SFX-L 700W PSU? Perhaps you have forgotten about the new form factor of PSU that offers similar cooling to a full ATX PSU but takes up a lot less room. Not to fret, [H]ard|OCP is here to remind you with a fresh review of the PSU. Their tests revealed the same strengths as Lee's, perhaps not outstanding but certainly a very good choice for a PSU. They did dock more points for the lack of an included adapter for ATX mounting, they are available but it does seem worth mentioning SilverStone's oversight.
"SilverStone has a new take on small form factor power supplies it is calling "SFX-L." This new form factor extends the standard SFX size by 30mm allowing SilverStone to install a quieter 120mm fan than the usual higher speed and noisier 80mm and 92mm fans. How does all this work out?"

Ever wonder how efficiently a major venue operates when it's only full of fans on game days? It turns out they don't operate all that efficiently, and the overhead is very expensive. This is where Qualcomm and OSIsoft step in, collaborating on a new “Smart Ballpark” project for San Diego's Petco Park.
“The San Diego Padres are utilizing edge intelligence gateways, powered by Qualcomm Snapdragon processors, to collect data from critical infrastructure systems and stream it in real-time to OSIsoft’s PI System in order to monitor utilities, improve operating efficiencies and drive sustainability across the team’s entire Petco Park ballpark.”
With usage monitoring for utilities (electrical and gas energy, potable and non-potable water) the Padres - San Diego’s Major League Baseball team that calls Petco Park home - see the potential to save more than 25% in the next five years.
“The edge intelligence gateways, using Snapdragon processors, connect to sensors and legacy systems throughout the ballpark using a broad range of communication methods, including wired and wireless technologies, analog and digital inputs and multiple communication protocols. These edge intelligence gateways acquire, store and stream data in real-time to the OSIsoft PI System which then presents the data to the Padres’ facilities managers using OSIsoft’s Visualization Suite and analytics, providing the operations team with deep situational awareness of everything happening in the venue.”
This is a mammoth implementation of IoT (Internet of Things), with OSIsoft’s PI system a major player on the industrial side. Qualcomm naturally needs no introduction, as the smartphone SoC maker found in so many devices across virtually all brands. Qualcomm has also worked on improving mobile data performance in large venues such as ballparks, with products like the X16 modem (expected in products starting in the second half of 2016) offering improved connections via carrier and link aggregation, and use of unlicensed spectrum.
