The Diamond Xtreme Sound XS71HDU could be a versitile $60 solution for those with high end audio equipment that would benefit from a proper DAC. With both optical in and out it is capable of more than an onboard solution, not to mention the six 3.5-mm jacks for stereo headphones, 7.1 surround support with rear, sub, side, mic, and line in. The design and features are impressive however the performance failed to please The Tech Report who felt that there were similar solutions with much higher quality sound reproduction.
"We love sound cards here at TR, but they don't fit in every kind of PC. Diamond's Xtreme Sound XS71HDU serves up the same kinds of features in a tiny USB package suitable for mini-PCs and ultrabooks. We took it for a spin to see if it's as good as it looks."

For many Linux is a mysterious thing that is either dead or about to die because no one uses it. Linux.com has put together an overview of what Linux is and where to find it being used. Much of what they describe in the beginning applies to all operating systems as they share similar features, it is only in the details that they differ. If you have only thought about Linux as that OS that you can't game on then it is worth taking a look through the descriptions of the distributions and why people choose to use Linux. You may never build a box which runs Linux but if you are considering buying a Steambox when they arrive on the market you will find yourself using a type of Linux and having a basic understanding of the parts of the OS for troubleshooting and optimization. If you already use Linux then fire up Steam and take a break.
"For those in the know, you understand that Linux is actually everywhere. It's in your phones, in your cars, in your refrigerators, your Roku devices. It runs most of the Internet, the supercomputers making scientific breakthroughs, and the world's stock exchanges."

Tagged: siggraph 2014, Siggraph, microsoft, Intel, DirectX 12, directx 11, DirectX
Along with GDC Europe and Gamescom, Siggraph 2014 is going on in Vancouver, BC. At it, Intel had a DirectX 12 demo at their booth. This scene, containing 50,000 asteroids, each in its own draw call, was developed on both Direct3D 11 and Direct3D 12 code paths and could apparently be switched while the demo is running. Intel claims to have measured both power as well as frame rate.
Variable power to hit a desired frame rate, DX11 and DX12.
The test system is a Surface Pro 3 with an Intel HD 4400 GPU. Doing a bit of digging, this would make it the i5-based Surface Pro 3. Removing another shovel-load of mystery, this would be the Intel Core i5-4300U with two cores, four threads, 1.9 GHz base clock, up-to 2.9 GHz turbo clock, 3MB of cache, and (of course) based on the Haswell architecture.
While not top-of-the-line, it is also not bottom-of-the-barrel. It is a respectable CPU.
Intel's demo on this processor shows a significant power reduction in the CPU, and even a slight decrease in GPU power, for the same target frame rate. If power was not throttled, Intel's demo goes from 19 FPS all the way up to a playable 33 FPS.
Intel will discuss more during a video interview, tomorrow (Thursday) at 5pm EDT.
Maximum power in DirectX 11 mode.
For my contribution to the story, I would like to address the first comment on the MSDN article. It claims that this is just an "ideal scenario" of a scene that is bottlenecked by draw calls. The thing is: that is the point. Sure, a game developer could optimize the scene to (maybe) instance objects together, and so forth, but that is unnecessary work. Why should programmers, or worse, artists, need to spend so much of their time developing art so that it could be batch together into fewer, bigger commands? Would it not be much easier, and all-around better, if the content could be developed as it most naturally comes together?
That, of course, depends on how much performance improvement we will see from DirectX 12, compared to theoretical max efficiency. If pushing two workloads through a DX12 GPU takes about the same time as pushing one, double-sized workload, then it allows developers to, literally, perform whatever solution is most direct.
Maximum power when switching to DirectX 12 mode.
If, on the other hand, pushing two workloads is 1000x slower than pushing a single, double-sized one, but DirectX 11 was 10,000x slower, then it could be less relevant because developers will still need to do their tricks in those situations. The closer it gets, the fewer occasions that strict optimization is necessary.
If there are any DirectX 11 game developers, artists, and producers out there, we would like to hear from you. How much would a (let's say) 90% reduction in draw call latency (which is around what Mantle claims) give you, in terms of fewer required optimizations? Can you afford to solve problems "the naive way" now? Some of the time? Most of the time? Would it still be worth it to do things like object instancing and fewer, larger materials and shaders? How often?

Tagged: tonga, radeon, FirePro W7100, amd
A little secret popped out with the release of AMD's FirePro W7100, a new family of GPU that goes by the name of Tonga, which is very likely to replace the aging Tahiti chip that has been used since the HD 7900 series. The stats that The Tech Report saw show interesting changes from Tahiti including a reduction of the memory interface to 256-bit which is in line with NVIDIA's current offerings. The number of stream processors might be reduced to 1792 from 2048 but that is based on the W7100 and it the GPUs may be released with the full 32 GCN compute units. Many other features have seen increases, the number of Asynchronous Compute Engines goes from 2 to 8, the number of rasterized triangles per clock doubles to 4 and it adds support for the new TrueAudio DSP and CrossFire XDMA.
"The bottom line is that Tonga joins the Hawaii (Radeon R9 290X) and Bonaire (R7 260X) chips as the only members of AMD' s GCN 1.1 series of graphics processors. Tonga looks to be a mid-sized GPU and is expected to supplant the venerable Tahiti chip used in everything from the original Radeon HD 7970 to the current Radeon R9 280."

Tagged: valve, source engine, Source 2, DOTA 2
While it may not seem like it in North America, we are in a busy week for videogame development. GDC Europe, which stands for Game Developers Conference Europe, is just wrapping up to make room for Gamescom, which will take up the rest of the week. Valve will be there and people are reading tea leaves to find out why. SteamOS seems likely, but what about their next generation gaming engine, Source 2? Maybe it already happened?
Valve is the most secretive company with values of openness that I know. They are pretty good at preventing leaks from escaping their walls. Recently, Dota 2 was updated to receive new features and development tools for user-generated maps and gametypes. The tools currently require 64-bit Windows and a DirectX 11-compatible GPU.
Those don't sound like Source requirements...
And the editor doesn't look like Valve's old tools.
Video Credit: "Valve News Network".
Leaks also point to things like "tf_imported", "left4dead2_source2", and "left4dead2_imported". This is interesting. Valve is pushing Dota 2, their most popular, free-to-play game into Source 2. Also, because it is listed as "tf" rather than "tf2", like "dota" is not registered as "dota2" but "left4dead2" keeps its number, this might mean that the free-to-play Team Fortress 2 could be in a perpetual-development mode, like Dota 2. Eventually, it could be pushed to the new engine and given more content.
As for Left4Dead2? I am wondering if it is intended to be a product, rather than an internal (or external) Source 2 tech demo.
Was this what brought Valve to Gamescom, or will be be surprised by other announcements (or nothing at all)?

Tagged: Intel, haswell, tsx, errata
Transactional Synchronization Extensions, aka TSX, are a backwards compatible set of instructions which first appeared in some Haswell chips as a method to improve concurrency and multi-threadedness with as little work for the programmer as possible. It was intended to improve the scaling of multi-threaded apps running on multi-core processors and has not yet been widely adopted. The adoption has run into another hurdle, in some cases the use of TSX can cause critical software failures and as a result Intel will be disabling the instruction set via new BIOS/UEFI updates which will be pushed out soon. If your software uses the new instruction set and you wish it to continue to do so you should avoid updating your motherboard BIOS/UEFI and ask your users to do the same. You can read more about this bug/errata and other famous problems over at The Tech Report.
"The TSX instructions built into Intel's Haswell CPU cores haven't become widely used by everyday software just yet, but they promise to make certain types of multithreaded applications run much faster than they can today. Some of the savviest software developers are likely building TSX-enabled software right about now."

Tagged: amd, seattle, hot chips
AMD has been showing off a reference Seattle-based server at Hot Chips and The Tech Report had an opportunity to see it. Eight 64-bit Cortex-A57 chips are set up in pairs, each pair sharing 1MB of L2 cache while the 8MB of L3 cache is accessible by all eight chips as well as the coprocessors, memory controller, and I/O subsystems. The system can address up to 128GB of DDR3 or DDR4, and you get support fot 8 SATA 6Gbps ports and 8 lanes of PCIe 3.0 to apportion between the slots. There is a secure System Control Processor, a partitioned Cortex-A5 core with its own ROM, RAM, and I/O to control power, boot and configuration control with support for TrustZone as well as a Cryptographic Coprocessor which accelerates all encryption processes as you might well expect. Read on for more information about AMD's unique new take on server technology.
"For some time now, the features of AMD's Seattle server processor have been painted in broad brush strokes. This morning, at the Hot Chips symposium, AMD is filling in most of the missing details. We were treated to an advance briefing last week, where AMD provided previously confidential information about Seattle's cache network, memory controller, I/O features, and coprocessors."

Tagged: webgl, tegra k1, nvidia, geforce, Chromebook, Bay Trail, acer
Today Acer unveiled a new Chromebook powered by an NVIDIA Tegra K1 processor. The aptly-named Chromebook 13 is 13-inch thin and light notebook running Google’s Chrome OS with up to 13 hours of battery life and three times the graphical performance of existing Chromebooks using Intel Bay Trail and Samsung Exynos processors.
The Chromebook 13 is 18mm thick and comes in a white plastic fanless chassis that hosts a 13.3” display, full size keyboard, trackpad, and HD webcam. The Chromebook 13 will be available with a 1366x768 or 1920x1080 resolution panel depending on the particular model (more on that below).
Beyond the usual laptop fixtures, external I/O includes two USB 3.0 ports, HDMI video output, a SD card reader, and a combo headphone/mic jack. Acer has placed one USB port on the left side along with the card reader and one USB port next to the HDMI port on the rear of the laptop. Personally, I welcome the HDMI port placement as it means connecting a second display will not result in a cable invading the mousing area should i wish to use a mouse (and it’s even south paw friendly Scott!).
The Chromebook 13 looks decent from the outside, but it is the internals where the device gets really interesting. Instead of going with an Intel Bay Trail (or even Celeron/Core i3), Acer has opted to team up with NVIDIA to deliver the world’s first NVIDIA-powered Chromebook.
Specifically, the Chromebook 13 uses a NVIDIA Tegra K1 SoC, up to 4GB RAM, and up to 32GB of flash storage. The K1 offers up four A15 CPU cores clocked at 2.1GHz, and a graphics unit with 192 Kepler-based CUDA cores. Acer rates the Chromebook 13 at 11 hours with the 1080p panel or 13 hours when equipped with the 1366x768 resolution display. Even being conservative, the Chromebook 13 looks to be the new leader in Chromebook battery life (with the previous leader claiming 11 hours).
A graph comparing WebGL performance between the NVIDIA Tegra K1, Intel (Bay Trail) Celeron N2830, Samsung Exynos 5800, and Samsung Exynos 5250. Results courtesy NVIDIA.
The Tegra K1 is a powerful little chip, and it is nice to see NVIDIA get a design win here. NVIDIA claims that the Tegra K1, which is rated at 326 GFLOPS of compute performance, offers up to three times the graphics performance of the Bay Trail N2830 and Exynos 5800 SoCs. Additionally, the K1 reportedly uses slightly less power and delivers higher multi-tasking performance. I’m looking forward to seeing independent reviews in this laptop formfactor and hoping that the chip lives up to its promises.
The Chromebook 13 is currently up for pre-order and will be available in September starting at $279. The Tegra K1-powered laptop will hit the United States and Europe first, with other countries to follow. Initially, the Europe roll-out will include “UK, Netherlands, Belgium, Denmark, Sweden, Finland, Norway, France, Germany, Russia, Italy, Spain, South Africa and Switzerland.”
Acer is offering three consumer SKUs and one education SKU that will be exclusively offering through a re-seller. Please see the chart below for the specifications and pricing.
|Acer Chromebook 13 Models||System Memory (RAM)||Storage (flash)||Display||Price MSRP|
|CB5-311-T9B0||2GB||16GB||1920 x 1080||$299.99|
|CB5-311-T1UU||4GB||32GB||1920 x 1080||$379.99|
|CB5-311-T7NN - Base Model||2GB||16GB||1366 x 768||$279.99|
|Educational SKU (Reseller Only)||4GB||16GB||1366 x 768||$329.99|
Intel made some waves in the Chromebook market earlier this year with the announcement of several new Intel-powered Chrome devices and the addition of conflict-free Haswell Core i3 options. It seems that it is now time for the ARM(ed) response. I’m interested to see how NVIDIA’s newest model chip stacks up to the current and upcoming Intel x86 competition in terms of graphics power and battery usage.
As far as Chromebooks go, if the performance is at the point Acer and NVIDIA claim, this one definitely looks like a decent option considering the price. I think a head-to-head between the ASUS C200 (Bay Trail N2830, 2GB RAM, 16GB eMMC, and 1366x768 display at $249.99 MSRP) and Acer Chromebook 13 would be interesting as the real differentiator (beyond aesthetics) is the underlying SoC. I do wish there was a 4GB/16GB/1080p option in the Chromebook 13 lineup though considering the big price jump to get 4GB RAM (mostly as a result of the doubling of flash) in the $379.99 model at, say, $320 MSRP.

Tagged: ssd, radeon r7, confusing, amd, 19nm
In a branding move that has no possibility of causing confusion, AMD has announce the name of their new SSD line and it seems that the next Radeon R7 240 you buy might be a GPU or then again it might not be. Brand confusion aside, the drives will use 19nm Toshiba NAND fabbed at SanDisk and are predicted to perform similar to other drives with the same NAND, reads of 550MBps and 530MBps write. However as we well know the key to performance lies in the controller and the number of channels so it will be interesting to see the first benchmarks. As The Inquirer points out this could lead to the release of AMD branded machines, containing AMD made APU, RAM, SSD and discrete GPU.
"The Radeon R7 range consisting of 120GB, 240GB and 480GB flavours and is designed to appeal to the gaming market, putting it in direct competition with Micron's Crucial range which expanded to include the MX100, which premiered earlier this year claiming 89 percent performance improvement over a standard hard drive."

Tagged: ssd, phase change memory, PCM, hgst, FMS 2014, FMS
According to an HGST press release, the company will bring an SSD based on phase change memory to the 2014 Flash Memory Summit in Santa Clara, California. They claim that it will actually be at their booth, on the show floor, for two days (August 6th and 7th).
The device, which is not branded, connects via PCIe 2.0 x4. It is designed for speed. It is allegedly capable of 3 million IOPS, with just 1.5 microseconds required for a single access. For comparison, the 800GB Intel SSD DC P3700, recently reviewed by Allyn, had a dominating lead over the competitors that he tested. It was just shy of 250 thousand IOPS. This is, supposedly, about twelve times faster.
While it is based on a different technology than NAND, and thus not directly comparable, the PCM chips are apparently manufactured at 45nm. Regardless, that is significantly larger lithography than competing products. Intel is manufacturing their flash at 20nm, while Samsung managed to use a 30nm process for their recent V-NAND launch.
What does concern me is the capacity per chip. According to the press release, it is 1Gb per chip. That is about two orders of magnitude smaller than what NAND is pushing. That is, also, the only reference to capacity in the entire press release. It makes me wonder how small the total drive capacity will be, especially compared to RAM drives.
Of course, because it does not seem to be a marketed product yet, nothing about pricing or availability. It will almost definitely be aimed at the enterprise market, though (especially given HGST's track record).
*** Update from Allyn ***
I'm hijacking Scott's news post with photos of the actual PCM SSD, from the FMS show floor:
In case you all are wondering, yes, it does in fact work:
One of the advantages of PCM is that it is addressed at smaller sections as compared to typical flash memory. This means you can see ~700k *single sector* random IOPS at QD=1. You can only pull off that sort of figure with extremely low IO latency. They only showed this output at their display, but ramping up QD > 1 should reasonably lead to the 3 million figure claimed in their release.

The new cooling on the 290X tends to have it at the top of the gaming charts and with the impending release of two new FirePro HPC cards AMD looks to take the productivity title away from the Tesla K40. The higher end S9150 boasts 16GB GDDR5 memory with a 512-bit memory interface, 44 GCN compute units with 64 stream processors each there is a total of 2816 stream processors on board. That equates to 5.07 TFLOPS peak single-precision 2.53 TFLOPS peak double-precision performance with theoretical memory bandwidth of 320GB per second. AMD expects the S9150 to have support for OpenCL 2.0 drivers by the end of the year, which the lower priced and specced S9050 will not though both will support AMD Stream technology and OpenCL 1.2. Check them out at The Register.
"The company's new big gun is the FirePro S9150 card, which maxes out at a blistering 5.07 TFLOPS peak single-precision floating-point performance and 2.53 TFLOPS peak double-precision performance."

Tagged: origin, on the house, free, free games
Origin, with its On the House program, has been releasing games for free, to promote their distribution platform. This time, they dug deep in the back catalog and pulled out Wing Command 3: Heart of the Tiger. This DOS-era game is the last of the three focused on "The Confederation" versus "The Kilrathi". It was also the first to use "full motion video", headlined by Mark Hamill, rather than animated cutscenes. "On the House" makes it free forever, if you declare your interest before the promotion ends.
It is also available at Good Old Games, for $5.99, but it does go on sale from time to time. At the very least, it is probably worth picking it up on Origin and, if you like it, pick up the DRM-free version at GoG.com for safe archival.
And if you don't like it? Well, you're not out much, are you?

Tagged: keyboard, travel keyboard, htpc keyboard
So, I am writing about a wireless, non-mechanical keyboard.
Mad Catz has made a weird keyboard layout. Honestly, it looks like something from a 1990's-era sci-fi video game. I could imagine "Lev Arris" pulling it out of his trench coat while discussing space pirates. It also includes mouse and media functionality, even when pairing with Android and iOS devices (it connects with Macs and PCs, too). It's also small.
As stated earlier, its keys are not mechanical. They are, also, not membrane-dome. The keys are based on scissor-switches, common with laptop keyboards. While I do not know the specifics of this keyboard, I do not know of any scissor-switch keyboard with removable keys. This means that, if something gets stuck under a keycap, you cannot remove it (unless you intend to never put it back on). Again, Mad Catz could have done something special, but it is something to think about -- especially if you intend on using this keyboard in the living room while eating.
The keyboard has an adjustable, white backlight for the "main" keys. It is, also, $100. This is definitely a unique design, tailored for a living room (or hotel room) experience. It is not cheap, but interesting. I could see it being useful, especially if a user could use it for both their living room, and during travel.

Tagged: best buy, tablets, convertible, laptop
Hubert Joly, CEO of Best Buy, talked with Re/code about the overall health of their company and various industry trends. The first question (at least in the order Re/code presented them) asked about the decline of the PC industry. He responded that PC sales are actually recovering, to some extent, but that Android tablets are, now, "crashing".
His view is that laptops are adopting the successful bits of the tablet market, especially as a result of various two-in-one initiatives. He believes students, in particular, appreciate tablet/laptop hybrids. This is certainly what Intel has been hoping for, through its recent Ultrabook efforts. He hopes that innovation will be done at the high end, so consumers will not simply settle for the $300-tier.
He did back off on his "crashed" statement, regarding the tablet market, however. The growth of tablets, from the start, were amazing. However, like the argument with "good enough" PCs, there does not seem to be a compelling argument for users to move to the next device, at least not yet. Like PCs, devices are being replaced, just not driven from industry forces. Also, like smartphones, the market seems to have matured, slowing in growth.
Naturally, Joly believes that Best Buy will be around for years to come. I agree with his reasoning. He acknowledges the squeeze between online resellers and boutique shops, which puts Best Buy in an awkward middle niche when the goal of a big box store is to be not niche. My interpretation of his strategy is to, instead of being crushed, strive to overlap. Embrace what the customers want on either side while doing your thing in the middle.
It is still questionable whether it will work, but it seems like the right move.
