AAEON's SoC is an impressive implementation of Bay Trail

Subject: Systems | April 10, 2014 - 02:57 PM |
Tagged: linux, mini-itx, AAEON, EMB-BT1, Bay Trail, SFF, htpc

You may not recognize the name AAEON but you will recognize its parent company, ASUS.  AAEON makes low power small form factor single board SoCs and with the introduction of Bay Trail they may become more common.  The EMB-BT1-A10-3825 sports a quad-core Atom E3845 @ 1.33GHz and Ivy Bridge era Intel HD graphics with support for up to 4GB of DDR3-1067.  It has a total TDP of 6W but unfortunately Phoronix's WattsUp meter was busy on another system so you will need to wait for an update on total power consumption.

The connectivity on this SoC is incredible, mSATA for an SSD, two SATA 6Gbps ports and two SATA-2 ports, dual gigabit LAN ports, a pair of USB 2.0 ports and a single 3.0 port, HDMI, VGA, COM, and audio jacks.  You could configure this as a small media server or as it supports dual displays it would serve wonderfully as an HTPC.

"For those after a low-cost mini-ITX board for use within an HTPC, SOHO file server, or other low-power situations, AAEON has out an interesting board called the EMB-BT1, or more formally the AAEON EMB-BT1-A10-3825. This mini-ITX motherboard has onboard an Intel Atom E3825 "Bay Trail" SoC for delivering decent performance out of the six Watt SoC and having open-source-friendly graphics under Linux."

Raspberry Pi Compute Module Will Work With Custom PCBs

Subject: General Tech | April 10, 2014 - 01:55 PM |
Tagged: videocore iv, Raspberry Pi, bcm2835, arm

Although the Raspberry Pi's original purpose was as an educational tool, many enthusiasts have used the (mostly) open source hardware at the heart of home automation, robotics projects, and other embedded systems. In light of this success, the Raspberry Pi Foundation has unveiled the Raspberry Pi Compute Module, a miniaturized version of the Raspberry Pi sans IO ports that fits onto a single SO-DIMM module. The Compute Module houses the BCM2835 SoC, 512MB of RAM, and 4GB of flash memory and can be paired with custom designed PCBs.

The Raspberry Pi Compute Module. Note that the pin out is entirely different from a memory module, so don't try plugging this into your laptop!

The Compute Module will initially be released along with an open source breakout board called the Compute Module IO Board. The IO Board is intended to be an example to get users started and to help them along the path of designing their own customized PCB. The IO Board has a SO-DIMM connector that the Compute Module plugs into. It further offers up two serial camera ports, two serial display ports, two banks of 2x30 GPIO pinouts, a micro USB port for power, one full-size USB port, and one HDMI output. The Raspberry Pi Foundation will be releasing full documentation and schematics for both the Compute Module and IO Board over the next few weeks.

Using the Compute Module and a custom PCB, the embedded system can be smaller and lighter than then traditional Raspberry Pi.

The Raspberry Pi Compute Module and IO Board will be available as a bundle (the "Compute Module Development Kit") from Element14 and RS in June. Shortly after the development kit launch, customers will be able to purchase the compute module itself for $30 each in batches of 100 or slightly more for smaller orders.

More information can be found on the Raspberry Pi blog. Here's hoping the industrial / embedded market successes will help fuel additional educational endeavours and new Raspberry Pis versions in the future.

Your date with the Haswell refresh has been postponed

Tagged: Intel, haswell, i7-4790

If you have been anxiously awaiting the release of the new Core i7-4790 and 9-series of chipsets from Intel, you are going to be waiting a bit longer.  DigiTimes is reporting that the negative feedback from vendors has convinced them to delay releasing the new chip and chipset for another month.  This is likely due to the number of current generation Haswell chips, motherboards and systems stuck in the channel thanks that vendors are hoping will sell thanks to the EoL of WinXP.  The numbers from Gartner support their theory, the long downwards trend of PC sales has leveled off in the last quarter.  We can only hope that there will be discounts and sales towards the end of the month to help clean out the channel for the release of the new generation of Haswell processors.

If you were impressed by the low wattage required to run the AMD AM1 Athlon 5350 and are thinking of building a low power system along the lines of the one Josh used in his review Kingston has a product to help you lower that total system voltage a little more.  HyperX Genesis LoVo uses only a mere 1.35V to power the 16GB DDR3-1600 CL9 kit and their low profile helps if you are building a small sized system.  Performance at stock speeds is quite decent, with the possibility of overclocking to add more speed if you desire but these DIMMs are more about power savings than raw power.  Check out the full review at Funky Kit.

Kingston_LoVo_pht2.jpg

"Even though higher clocked RAM is great for overclocking and gaming for most computer users, memory at lower clocks is good enough for the general tasks they perform daily. For those users, memory speed is usually less important than capacity so today we wish to present something more regular in the memory's world what is Kingston HyperX Genesis LoVo 16GB DDR3-1600 CL9. As probably some readers already noticed, we can't really call it regular memory as Kingston specified it to run at low voltage of 1.35V ... and it's green like most eco-friendly products."

Tagged: linux, asus, zenbook, UX301LA-DH71T, ubuntu 14.04, ubuntu, haswell

There is a lot to like about this particular 13.3" ASUS Zenbook, perhaps the most noticeable is the IPS display with a 2560 x 1440 resolution and a capacitive display capable of tracking 10 contact points.  There is another reason to fall in love with this notebook, it can run Ubuntu with all of the features enabled without any extra work required.  The specifications under the hood are rather impressive as well, a Core-i7 4558U with Intel Iris Graphics 5100, 8GB of DDR3-1600 and two 128GB SSDs capable of supporting RAID.  Those of you looking for a powerful notebook which does not require Windows to run properly would be wise to read this review at Phoronix.

"As I wrote about at the beginning of March, I bought the ASUS Zenbook UX301LA-DH71T Haswell-based ultrabook to replace an Apple Retina MacBook Pro as my main system. I've been using this latest Zenbook with Intel Iris Graphics and dual SSDs for several weeks now as my main system and have taken it on four business trips so far and it's been running great. Paired with Ubuntu 14.04 LTS, the ASUS Zenbook UX301LA makes a rather nice lightweight yet powerful Linux system."

Google has an offer you might not refuse

Tagged: google, winxp, Chromebook

Google has an offer for businesses that it hopes will be attractive enough to get them to abandon Windows complete instead of upgrading from WinXP to a new version of a Microsoft OS.  They are offering businesses $100 off any managed Chromebook or other ChromeOS device and $200 if it will be running VMWare Desktop as a Service.  For those who have to go through major upgrades and software re-writes this might be a reasonable alternative since these companies are less than pleased at the EOL of WinXP and now have an opportunity to try or at least test an alternative OS.  It is unlikely that Windows will go the way of "tamagotchis and parachute pants" Google's Amit Singh is quoted as saying by The Inquirer but the demise of WinXP offers a unique opportunity for change to many businesses which has previously been economically unfeasable.

AMD Brings Kabini to the Desktop

Perhaps we are performing a study of opposites?  Yesterday Ryan posted his R9 295X2 review, which covers the 500 watt, dual GPU monster that will be retailing for $1499.  A card that is meant for only the extreme enthusiast who has plenty of room in their case, plenty of knowledge about their power supply, and plenty of electricity and air conditioning to keep this monster at bay.  The product that I am reviewing could not be any more different.  Inexpensive, cool running, power efficient, and can be fit pretty much anywhere.  These products can almost be viewed as polar opposites.

am1_APU_Comp.jpg

The interesting thing of course is that it shows how flexible AMD’s GCN architecture is.  GCN can efficiently and effectively power the highest performing product in AMD’s graphics portfolio, as well as their lowest power offerings in the APU market.  The performance scales very linearly when it comes to adding in more GCN compute cores.

The product that I am of course referring to are the latest Athlon and Sempron APUs that are based on the Kabini architecture which fuses Jaguar x86 cores with GCN compute cores.  These APUs were announced last month, but we did not have the chance at the time to test them.  Since then these products have popped up in a couple of places around the world, but this is the first time that reviewers have officially received product from AMD and their partners.

Seagate Packs 6TB Into 3.5" 7200 RPM Enterprise Capacity Hard Drive

Subject: Storage | April 8, 2014 - 11:22 PM |
Tagged: Seagate, sata 6Gbs, SAS, Hard Drive, enterprise, 6tb

Seagate's latest enterprise class hard drive offers up to 6TB of space in a 3.5" form factor. The Enterprise Capacity series drive comes in both SATA III 6Gbps and 12Gbps SAS interfaces. Seagate was able to achieve an impressive 1,000 Gb/inch or about 1.25 TB per platter with the drive's five total platters adding up to the 6TB capacity. Perhaps even more impressively, Seagate was able to offer up a 6TB, five platter, 7,200 RPM drive without using helium.

The 6TB Enterprise Capacity hard drive comes with a 128MB DRAM cache. It is rated at 216 MB/s for sequential transfer speeds and an average latency of 4.16 milliseconds. The drive also supports 256-bit AES encryption and an instant secure erase function which overwrites data multiple times. Seagate further claims the drive is rated for 24/7 workloads at 550TB/year with a MTBF of 1.4 million hours. The drive comes with a five year warranty.

Seagate Enterprise Capacity 6TB Hard Drive.jpg

The drive will come in several variants depending on the storage interface. LaCie has already committed to using the new drives in its dual bay external storage products. Seagate has not released pricing on the new 6TB drive, but stated that it would price the drive at the same $/GB as last year's 4TB model. Expect the price to be around $650 MSRP before contract and bulk order deals.

It is a neat drive for sure, and I hope that the technology trickles down to the consumer space quickly, as 4TB has been the maximum single drive capacity for far too long!

For now, the drive will be used in the datacenter, production house, and security/surveillance markets (particularly in the datacenter market where rack space is at a premium).

Noctua NH-D15 CPU Cooler Announced

Subject: General Tech, Cases and Cooling | April 8, 2014 - 08:44 PM |
Tagged: cpu cooler, NH-D15, noctua

Known primarily for large and quiet CPU coolers, Noctua is not shy to attach a pair of 140mm fans to a chunk of metal. The NH-D15, announced today, can cool just about any current, mainstream or enthusiast CPU from AMD or Intel. It attaches to the CPU with a copper plate, which is connected to several copper heatpipes, which leads into two towers of aluminum fins. It is plated with nickel to prevent corrosion (I am not sure about the bottom).

As is common for these types of heat sinks, they are daunting to look at. Of course, that is not a bad thing, unless you have a very small case, but it might make you look at your stock fan differently. Noctua is claiming that their two fans spin at a maximum of 1500 RPM and a minimum of 300 RPM. This leads to a listed maximum noise value of 24.6 dBA, around the background noise of a quiet rural area at night.

The NH-D15 will be available mid-April for just shy of $100 USD.

Qualcomm Reveals New Flagship Snapdragon 808 and 810 64-Bit SoCs Coming In 2015

Subject: Mobile | April 8, 2014 - 07:47 PM |
Tagged: SoC, snapdragon, qualcomm, LTE, ARMv8, adreno, 64-bit

Qualcomm has announced two new flagship 64-bit SoCs with the Snapdragon 808 and Snapdragon 810. The new chips will begin sampling later this year and should start showing up in high end smartphones towards the second half of 2015. The new 800-series parts join the previously announced mid-range Snapdragon 610 and 615 which are also 64-bit ARMv8 parts.

The Snapdragon 810 is Qualcomm's new flagship processor. The chip features four ARM Cortex A57 cores and four Cortex A53 cores in a big.LITTLE configuration, an Adreno 430 GPU, and support for Category 6 LTE (up to 300 Mbps downloads) and LPDDR4 memory. This flagship part uses the 64-bit ARMv8 ISA. The new Adreno 430 GPU integrated in the SoC is reportedly 30% faster than the Adreno 420 GPU in the Snapdragon 805 processor.

Qualcomm Snapdragon SoC.jpg

In addition to the flagship part, Qualcomm is also releasing the Snapdragon 808 which pairs two Cortex A57 CPU cores and four Cortex A53 CPU cores in a big.LITTLE configuration with an Adreno 418 (approximately 20% faster than the popular Adreno 320) GPU. This chip supports LPDDR3 memory and Qualcomm's new Category 6 LTE modem.

Both the 808 and 810 have Adreno GPUs which support OpenGL ES 3.1. The new chips support a slew of wireless I/O including Categrory 6 LTE, 802.11ac Wi-Fi, Bluetooth 4.1, and NFC.

Qualcomm is reportedly planning to produce these SoCs on a 20nm process. For reference, the mid-range 64-bit Snapdragon 610 and 615 use a 28nm LP manufacturing process. The new 20nm process (presumably from TSMC) should enable improved battery life and clockspeed headroom on the flagship parts. Exactly how big the mentioned gains will be will depend on the specific manufacturing process, with smaller gains from a bulk/planar process shrink or greater improvements coming from more advanced methods such as FD-SOI if the new chip on a 20nm process is the same transistor count as one on a 28nm process (which is being used in existing chips).

The 808 and 810 parts are the new high-end 64-bit chips which will effectively supplant the 32-bit Snapdragon 805 which is a marginal update over the Snapdragon 800. The naming conventions and product lineups are getting a bit crazy here, but suffice it to say that the 808 and 810 are the effective successors to the 800 while the 805 is a stop-gap upgrade while Qualcomm moves to 64-bit ARMv8 and secures manufacturing for the new chips which should be slightly faster CPU-wise, notably faster GPU-wise and more capable with the faster cellular modem support and 64-bit ISA support.

For those wondering, the press release also states that the company is still working on development of its custom 64-bit Krait CPU architecture. However, it does not appear that 64-bit Krait will be ready by the first half of 2015, which is why Qualcomm has opted to use ARM's Cortex A57 and A53 cores in its upcoming flagship 808 and 810 SoCs.

NAB 2014: Elgato Thunderbolt Dock Announced

Tagged: thunderbolt, NAB 14, NAB, Elgato

Hmm, this is more Thunderbolt than I think we heard all year. Is there like, a video production event going on right now? No matter, because news is news (and so are product announcements). The Elgato Thunderbolt Dock connects to Thunderbolt, go figure, and provides three USB 3.0 ports, one Gigabit Ethernet port, one HDMI 1.4 output, one 3.5mm headphone jack, and one 3.5mm microphone jack. It also has a second Thunderbolt port to daisy chain with other devices, which is a common trait in Thunderbolt devices. It will retail for $229.95.

Yup, it is a Thunderbolt accessory.

Why does it seem like every Mac user in commercials have a studio apartment???

It makes sense to see devices like this. Thunderbolt is really an extension of PCIe which allows anything that was once an add-in board to be connected externally, albeit with significantly reduced bandwidth compared to PCIe 3.0 16x. This looks very clean, tidy, and much more desirable than crawling under the desk and swapping wires and thumb drives in the darkness behind your PC.

I would like to see some benchmarks on this device, however. Clearly, the sum of these outputs should be higher than the bandwidth allowed by Thunderbolt (especially if daisy-chaining another Thunderbolt device). I wonder how efficient it will be at keeping high quality signals when several devices are connected and running simultaneously.

The Elgato Thunderbolt Dock is available now for computers with a Thunderbolt port and either Mac OSX 10.9 or Windows 8.1. I guess us Windows 7 fans need to get used to the dust bunnies behind our PCs for a little longer...

Today, Lenovo announced a refreshed lineup of its A-series tablets including the A7-50, A8, and A10. The new tablets take a common hardware platform and scale it from a 7-inch tablet to a 10-inch tablet with optional keyboard. All three tablets run the Android 4.2 operating system and will be available in May.

The new Lenovo TAB A-series is powered by a quad core MediaTek 8121 SoC clocked at 1.3 GHz paired with 1GB of LP-DDR2 memory and 16GB of internal flash storage. Users can add an additional 32GB of storage with a micro SD card. Networking is handled by an 802.11 b/g/n Wi-Fi and Bluetooth 4.0 radio along with an optional SIM card slot on certain models (cellular functionality not available in the North American market). The tablets come with IPS touchscreens with a resolution of 1280 x 800. Lenovo includes a 2MP webcam and a 5MP rear facing camera on all three A-series tablets. The A10 further adds stereo speakers and compatibility with a keyboard dock.

Lenovo rates all three tablets at eight hours of battery life.

Beyond the Lenovo TAB A10 being available with a Bluetooth keyboard dock, the only major differences between the new three A-series tablets are physical dimensions, screen size, and weight. The Lenovo TAB A7-50 measures 198x121.2x9.9mm and weighs 0.70 lbs. The TAB A8 meanwhile measures 217x136x8.9mm and weighs slightly more at 0.79 lbs. Finally, the TAB A10 measures 264x176.5x8.9mm and weighs 1.2 lbs.

The 7-inch Lenovo Tab A7-50 has an MSRP of $129 while the 8-Inch Tab A8 has an MSRP of $179. The 10.1-inch Tab A10 has a base price of $249 and is also available as a tablet and keyboard bundle for $299.

What do you think about Lenovo's new A-series lineup? On one hand, you have three size options at competitive prices, but on the other you only have a single option as far as internal specifications and screen resolution no matter the screen size. If you can live with the MTK 8121 and 1GB of RAM, they could be a viable option.

Some NVIDIA R337.50 Driver Controversy

Subject: General Tech, Graphics Cards | April 8, 2014 - 06:44 PM |
Tagged: nvidia, geforce, drivers

NVIDIA's GeForce 337.50 Driver was said to address performance when running DirectX 11-based software. Now that it is out, multiple sources are claiming the vendor-supplied benchmarks are exaggerated or simply untrue.

nvidia-337-sli.png

ExtremeTech compiled benchmarks from Anandtech and BlackHoleTec.

Going alphabetically, Anandtech tested the R337.50 and R331.xx drivers with a GeForce GTX 780 Ti, finding a double-digit increase with BioShock: Infinite and Metro: Last Light and basically zero improvement for GRID 2, Rome II, Crysis: Warhead, Crysis 3, and Company of Heroes 2. Adding a second GTX 780 Ti into the mix helped matters, seeing a 76% increase in Rome II and about 9% in most of the other titles.

BlackHoleTec is next. Testing the mid-range, but overclocked GeForce 760 between R337.50 and R335.23 drivers, they found slight improvements (1-3 FPS), except for Battlefield 4 and Skyrim (the latter is not DX11 to be fair) which noticed a slight reduction in performance (about 1 FPS).

ExtremeTech, finally, published one benchmark but it did not compare between drivers. All it really shows is CPU scaling in AMD GPUs.

Unfortunately, I do not have any benchmarks to present of my own because I am not a GPU reviewer nor do I have a GPU testbed. Ironically, the launch of the Radeon R9 295 X2 video card might have lessened that number of benchmarks available for NVIDIA's driver, who knows?

If it is true, and R337.50 does basically nothing in a setup with one GPU, I am not exactly sure what NVIDIA was hoping to accomplish. Of course someone was going to test it and publish their results. The point of the driver update was apparently to show how having a close relationship with Microsoft can lead you to better PC gaming products now and in the future. That can really only be the story if you have something to show. Now, at least I expect, we will probably see more positive commentary about Mantle - at least when people are not talking about DirectX 12.

If you own a GeForce card, I would still install the new driver though, especially if you have an SLi configuration. Scaling to a second GPU does see measurable improvements with Release 337.50. Even for a single-card configuration, it certainly should not hurt anything.

During the GPU Technology Conference last month, NVIDIA introduced a new annual grant called the Global Impact Award. The grant awards $150,000 to researchers using NVIDIA GPUs to research issues with worldwide impact such as disease research, drug design, medical imaging, genome mapping, urban planning, and other "complex social and scientific problems."

NVIDIA Global Impact Award.png

NVIDIA will be presenting the Global Impact Award to the winning researcher or non-profit institution at next year's GPU Technology Conference (GTC 2015). Individual researchers, universities, and non-profit research institutions that are using GPUs as a significant enabling technology in their research are eligible for the grant. Both third party and self-nomiations (.doc form) are accepted with the nominated candidates being evaluated based on several factors including the level of innovation, social impact, and current state of the research and its effectiveness in approaching the problem. Submissions for nominations are due by December 12, 2014 with the finalists being announced by NVIDIA on March 13, 2015. NVIDIA will then reveal the winner of the $150,000 grant at GTC 2015 (April 28, 2015).

The researcher, university, or non-profit firm can be located anywhere in the world, and the grant money can be assigned to a department, initiative, or a single project. The massively parallel nature of modern GPUs makes them ideal for many times of research with scalable projects, and I think the Global Impact Award is a welcome incentive to encourage the use of GPGPU in applicable research projects. I am interested to see what the winner will do with the money and where the research leads.

More information on the Global Impact Award can be found on the NVIDIA website.

When Adobe started to GPU-accelerate their applications beyond OpenGL, it started with NVIDIA and its CUDA platform. After some period of time, they started to integrate OpenCL support and bring AMD into the fold. At first, it was limited to a couple of Apple laptops but has since expanded to include several GPUs on both OSX and Windows. Since then, Adobe switched to a subscription-based release system and has published updates on a more rapid schedule. The next update of Adobe Premiere Pro CC will bring OpenCL to Intel Iris Pro iGPUs.

Of course, they specifically mentioned Adobe Premiere Pro CC which suggests that Photoshop CC users might be coming later. The press release does suggest that the update will affect both Mac and Windows versions of Adobe Premiere Pro CC, however, so at least platforms will not be divided. Well, that is, if you find a Windows machine with Iris Pro graphics. They do exist...

A release date has not been announced for this software upgrade.

NAB 2014: Thunderbolt Networking Announced for Windows

Video professionals are still interested in Thunderbolt in probably much the same way as Firewire needed to be pried from their cold, dead hands. It is a very high bandwidth connector, useful for sending and receiving 4K video. Also, it was originally exclusive to Apple so you can guess which industries were first-adopters. Intel has focused their Thunderbolt announcements on the National Association of Broadcasters (NAB) show. This year, Thunderbolt Networking will be available for Windows via a driver. This will allow any combination of Macs and Windows PCs to be paired together by a 10 Gigabit network.

Of course, this is not going to be something that you can plug into a router. This is a point-to-point network for sharing files between two devices... really fast. Perhaps one use case would be a workstation with a Mac and a Windows PC on a KVM switch. If both are connected with Thunderbolt 2, they could share the same storage pool.

While this feature already exists on Apple devices, the PC driver will be available... "soon".

Corsair Released Vengeance K70 Mechanical Keyboard

Update (4/8/2014 @ 8:48 PM EDT): Some commenters pointed out that the K70 already exists and has been on sale for quite some time. That is true, however Corsair has refreshed the line, apparently adding Cherry MX Blue and Brown along with the "original MX Red". It is a new product that will be released mid-April.

No, this is not the Cherry MX RGB keyboard; we still do not know when that will come out. The K70 is a mechanical keyboard made out of blackened (anodized) aluminum with red backlights in each keycap. It comes in either Cherry MX Blue, Red, or Brown. Unlike some of their previous models, every key is mechanical. It is advertised as "100% anti-ghosted with full n-key rollover". Being a USB keyboard, it is unclear whether it actually allows every key to be pressed simultaneously or whether it is limited by the interface.

That said, previous Corsair keyboards registered as 3 USB devices and split inputs between the three to overcome 6KRO limits, thus allowing for 18-key rollover. This should be sufficient for all quadridextrous typists. For the mental image of someone typing with their eight fingers, two thumbs, and all but two of their ten toes, you are welcome.

Also, and I have said this before, but it kills me when a keyboard based on an NKRO key matrix (even if it is limited by USB) needs to describe itself as "Anti-ghosting". Anti-ghosting is a hack which prevents unintended keypresses by locking-out the keyboard when it gets confused. Many keyboards, to save money, group keys together in their grid of circuits. Basically, each key is assigned to two circuits and the keyboard can thus see which switches are pressed by their pairings. The keyboard does not know how many switches are open on each circuit, just that at least one is. Ghosting occurs when three or more keypresses cause the same signals as four or more keys. The keyboard then has two options: register all possible keypresses or jam and ignore everything (anti-ghosting). An NKRO-based matrix uses diodes to further isolate keys so that each can be individually addressed.

Thus an NKRO keyboard never needs to jam. It is immune to the conditions. Unfortunately, if they did not advertise anti-ghosting, the uninformed will think it is an inferior keyboard... rather than so superior that it is immune to the problem in the first place.

Back on the Vengeance K70, it will be available this month for $129.99 USD (MSRP).
