Tagged: xbox one, xbox, Steam Controller, microsoft, E3 2015, E3 15, E3, controller
And, of course, Xbox One... but I can assume who is the bulk of my audience.
Microsoft announced the Xbox One Elite Controller at E3, which includes support for Windows 10. This is part of their initiative to amend relations with the PC gaming industry. They seem to be going about it by focusing on the high-end gamer first. If not, then I wonder why they chose a $150 controller as a leading product.
At that price, you could literally purchase three Steam Controllers from Valve instead of a single one of these, but whether you should... depends. In all honesty, I might end up purchasing both and doing a comparison between them over a variety of games. Of course, my primary input device is the mouse and keyboard for most games, but I occasionally add an early model Xbox 360 wired controller to the mix for Saint's Row, Grand Theft Auto, NASCAR 2003, and a few other titles.
The real disappointment is its D-Pad, though. It just cannot reliably send a single direction without sometimes accidentally sending others. This gets worse in games that are styled in the “8-bit” and “16-bit” era. I actually need to play most of those on a keyboard, which is a terrible experience. Valve's implementation looks interesting with the cross-shaped thumbpad, but Microsoft's new version has options: an old-fashioned cross as well as a nine-sectioned cup, called a “faceted D-pad”.
That leads into the main design of Microsoft's controller: customization. Two switches on the back of the controller allow the range of trigger motion to be limited on the fly. This is designed for games like Grand Theft Auto, where the player wants precise control over throttle and brake, but would prefer to rapidly max-out the trigger as fast as possible when shooting a weapon. With this controller, you flip the switch when you leave the car and, what normally would be some fraction of its range, would be considered “bottoming out” and it would apparently even physically stop the trigger from pushing in further. According to the website, the threshold is user-customizable. I did not use it personally because I wasn't at E3.
Like Valve's controller, it has optional rear paddles near the grips. They are stainless steel apparently, and can be used to compensate for weird button combinations by mapping them to fingers that normally just clutch the device itself. In Valve's version, there is just two while Microsoft's allows for up to four. Microsoft also allows you to detach them, rather than just disable them.
This is when we get to software customization. Valve claims that the Steam Controller can be bound to many events across mouse, keyboard, and gamepad buttons and axises. Microsoft, on the other hand, seems to be keeping within the range of buttons found on a standard Xbox One controller. This is concerning to me because it means that extended inputs will be redundant, which is fine for an Xbox One game but could be annoying for a PC title that has many independent, simpler commands. This might be a limitation of XINPUT, which supposedly cannot address more than 10 buttons. I thought I remembered that limit being extended, but that seems to be true even in the MSDN documentation. Even still, the driver could address the extra functions as a secondary virtual device (keyboards, etc.) but Microsoft doesn't seem to want to. As a final note, Valve also allows the end of both triggers to be considered a clicky button, while Microsoft just recognizes it as a bottomed-out axis.
The Xbox One Elite Controller will ship in October for $149.99. A wireless adapter for the PC will not be required if you use the included USB Micro cable, but add that to the price if you want it wireless. Add batteries on top of that, because it takes AA. They include a pair of disposable AA, but that is obviously not a permanent solution.

Tagged: sound card, powercolor, devil hdx, computex
PowerColor is best known as an add-in board (AIB) partner of AMD who has also branched out into cases and power supplies. This year, they have introduced a new product category: sound cards. The PowerColor Devil HDX connects via PCIe and can take up one or two slots, depending on whether the user wants to install its included (!!) daughterboard with analog (4 x 3.5mm) surround outputs and a microphone input. Without the daughterboard, the card has a quarter-inch headphone jack, two analog RCA jacks for stereo, an RCA SPDIF output, and an optical SPDIF output. The main card is covered in a full EMF shield, because it's inside a computer.
The card includes switchable OP-AMPs, high quality capacitors, a Cmedia CM8888 audio processor, and a Wolfson WM8741 DAC. This configuration is capable of driving headphones with up to 600 Ohm impedance. The signal-to-noise ratio is a little better on the RCA jacks, because they're not amplified, but not by much. The RCA jacks are rated at 124 dB SNR, while the headphones are rated at 120 dB SNR with the supplied OP-AMPs. PowerColor wrote a driver interface, called “Xear”, which includes ASIO 2.2 support.
The PowerColor Devil HDX doesn't have a release date but Tom's Hardware, who spoke with the company, said it should be “over the coming months”. They also said it will retail for $159, which is apparently $50 less than their competition.

While 16nm TLC was initially promised Q4 of 2014, I believe Micron distracted themselves a little with their dabbles into Dynamic Write Acceleration technology. No doubt wanting to offer ever more cost effective SSDs to their portfolio, the new TLC 16nm flash will take up less die space for the same capacity, meaning more dies per 300mm wafer, ultimately translating to lower cost/GB of consumer SSDs.
Micron's 16nm (MLC) flash
The Crucial MX200 and BX100 SSDs have already been undercutting the competition in cost/GB, so the possibility of even lower cost SSDs is a more than welcome idea - just so long as they can keep the reliability of these parts high enough. IMFT has a very solid track record in this regard, so I don't suspect any surprises in that regard.
Full press blast appears after the break.

OCZ is showing off some new goodies at Computex 2015 in the form of a completely new SSD model – the Trion:
The Trion is based on an in-house Toshiba ‘Alishan’ controller – the first internal design from that company. Since it is sourced from within Toshiba, the new SSD controller is to be tuned for consumer workloads and should employ lower power states than prior OCZ / Indilinx SSD controllers, as well as Toshiba’s own proprietary QSBC (Quadruple Swing-By Code) error correction technology, which should squeeze a bit more usable life out of the A19nm TLC flash. This is what QSBC looks like compared to competing BCH and LDPC technologies:
We suspect Toshiba dialed back the algorithm a bit for client usage, but it should still be far superior to BCH. We don’t have many more details as the Trion has not yet been officially launched, but we do have this shot of a round of benchmark results from a pre-production 960GB model:
From what we can see, it appears to be a good performer (by modern SATA 6Gb/sec SSD standards), but we naturally can't tell anything for sure until we get samples in for local testing, as we have no idea of the state of preconditioning of the Trion in those tests.
Also on display were the recently launched Z-Drive 6000 and 6300 Series parts:
These are OCZ’s enterprise-grade NVMe devices, available in 800GB, 1.6TB, and 3.2TB. The 6000 series is a 2.5” 15mm SFF-8639 device aimed at lighter workloads with a rating of 1 Drive Write Per Day (DWPD) over a 5-year period, while the 6300 series brings that figure up to 3 DWPD and offers an HHHL PCIe card as an optional form factor. The higher writes per day are facilitated by the move to A19nm eMLC flash.
We’ll be keeping a close eye on these new developments from OCZ and we are eager to get these in the shop for some thorough testing!
Press blast for the Trion and Z-Drive 6300 Series after the break!

Tagged: msi, killer nic, killer, computex 2015, computex, 802.11ac
Killer Networking has developed several networking solutions, focused on gamers, over the last decade or so. Ryan reviewed their first product way back in 2006, and he found it had some merit but struggled when quantifying it, especially to the price tag that it bore. Many years later, Qualcomm picked them up and their technology found a few design wins, especially with Gigabyte motherboards. They also branched out into wireless networking, a segment that undeniably could benefit from innovation. They are also, now, under the Rivet Networks brand, which is listed as an “Authorized Design Center” for Qualcomm.
Today, they are announcing the Killer Wireless-AC 1535 Networking Adapter. This brings their technology to the 802.11ac standard. It includes features like DoubleShow Pro, which allows Windows to balance network traffic between wireless and wired networks. It also allows the user to monitor their wireless traffic, even providing an interface to throttle or outright disable certain applications from using the internet. They are mostly promoting their “ExtremeRange” technology, which uses the MU-MIMO standard of 802.11ac, along with beamforming and two signal amplifiers, to provide high bandwidth at longer ranges.
The Killer Wireless-AC 1535 has received a few design wins, this time with MSI. It will be available in the MSI GT72 and MSI GT80 gaming laptops, as well as the MSI X99A GODLIKE GAMING motherboard. Thankfully, they are not adopting MSI's love of uppercase letters.

Tagged: Intel, computex 2015, computex, Broadwell
Earlier this morning you saw us post a story about MSI updating its line of 20 notebooks with new Broadwell processors. Though dual-core Broadwell has been available for Ultrabooks and 2-in-1s for some time already, today marks the release of the quad-core variations we have been waiting on for some time. Available for mobile designs, as well as marking the very first Iris Pro graphics implementation for desktop users, Broadwell quad-core parts look to be pretty impressive.
Today Intel gives to the world a total 10 new processors for content creators and enthusiasts. Two of these parts are 65 watt SKUs in LGA packaging for use by enthusiasts and DIY builders. The rest are BGA designs for all-in-one PCs and high performance notebooks and include both 65 watt and 47 watt variants. And most are using the new Iris Pro Graphics 6200 implementation.
For desktop users, we get the Core i7-5775C and the Core i5-5675C. The Core i7 model is a quad-core, HyperThreaded CPU with a base clock of 3.3 GHz and a max Turbo clock of 3.7 GHz. It's unlocked so that overclockers and can mess around with them in the same way do with Haswell. The Iris Pro Graphics 6200 can scale up to 1150 MHz and rated DDR3L memory speeds are up to 1600 MHz. 6MB of L3 cache, a 65 watt TDP and a tray price of $366 round out the information we have.
Click to Enlarge
The Core i5-5675C does not include HyperThreading, has clock speed ranges of 3.1 GHz to 3.6 GHz and only sees the Iris Pro scale to 1100 MHz. Also, it drops from 6MB of L3 cache to 4MB. Pricing on this model will start a $276.
These two processors mark the first time we have seen Iris Pro graphics in a socketed form factor, something we have been asking Intel to offer for at least a couple of generations. They focused on 65 watt TDPs rather than anything higher mostly because of the target audience for these chips: if you are interested in the performance of integrated graphics then you likely are pushing a small form factor design or HTPC of some kind. If you have a Haswell-capable motherboard then you SHOULD be able to utilize one of these new processors though you'll want a Z97 board if you are going to try to overclock it.
From a performance standpoint, the Core i7-5775C will offer 2x the gaming performance, 35% faster video transcoding and 20% higher compute performance when compared to the previous top-end 65 watt Haswell part, the Core i7-4790S. That 4th generation part uses Intel HD Graphics 4600 that does not include the massive eDRAM that makes Iris Pro implementations so unique.
For mobile and AIO buyers, Intel has a whole host of new processors to offer. You'll likely find most of the 65 watt parts in all-in-one designs but you may see some mobile designs that go crazy and opt for them too. For the rest of the gaming notebook designs there are CPUs like the Core i7-5950HQ, a quad-core HyperThreaded part with a base clock of 2.9 GHz and max Turbo clock of 3.8 GHz inside a TDP of 47 watts. The Iris Pro Graphics 6200 will scale from 300 to 1150 MHz so GPU performance should basically be on par with the desktop 65-watt equivalent. Pricing is pretty steep though: starting at $623.
Click to Enlarge
These new processors, especially the new 5950HQ, offer impressive compute and gaming performance.
Compared to the Core i7-5600U, already available and used in some SFF and mobile platforms, the Core i7-5950HQ is 2.5x faster in SPECint and nearly 2x faster in a video conversion benchmark. Clearly these machines are going to be potent desktop replacement options.
For mainstream gamers, the Iris Pro Graphics 6200 on 1920x1080 displays will see some impressive numbers. Players of League of Legends, Heroes of the Storm and WoW will see over 60 FPS at the settings listed in the slide above.
We are still waiting for our hardware to show up but we have both the LGA CPUs and notebooks using the BGA option en route. Expect testing from PC Perspective very soon!

Tagged: Android, google, google io, google io 2015
I'll be honest with you: I did not see a whole lot that interested me out of the Google I/O keynote. The company released a developer preview of their upcoming Android OS “M”, which refers to the thirteenth alphabetical release (although only eleven were formally lettered because they started with “C”upcake). Version nomenclature aside, this release is supposed to tune the experience. While the platform could benefit from a tune-up, it is also synonymous with not introducing major features.
But some things are being added, including “Google Now on Tap”. The idea is that Google will understand what is happening on screen and allow the user to access more information about it. In a demo on Engadget, the user was looking at scores for the Golden State Warriors. She asked “When are they playing next”, actually using the pronoun “they”, and the phone brought up their next game (it was against the Cavaliers).
Fingerprint reading and Android Pay are also being added to this release.
Other than that, it is mostly performance and usability. One example is “Doze State”, which allows the OS to update less frequently when the device is inactive. It is supposed to play nice with alarms and notifications though, which is good. Normally, I would wait to see if it actually works before commenting on it, but this seems like something that would only be a problem if no-one thought of it. Someone clearly did, because they apparently mentioned it at the event.
Android M, whatever it will actually be called, is expected to ship to consumers in the Fall.

Shortly after the keynote at Lenovo Tech World today,we got hands on with the Dual-Screen Smartwatch concept, the Magic View.
The Magic View is an Android Wear device, which integrates a unique “virtual interactive display" via a small prism on the watch band. Users must bring the device up to their face and look through the prism to see a secondary display for tasks such as video viewing.
Looking inside the Magic View reminded us a lot of Google Glass. As you put your eye up to the prism on the watch band, you could see what looked like a display off in the distance. It was difficult to determine the relative size, but Lenovo claims this display is 20x bigger than the display on the smartwatch itself. Resolution was also undetermined, but it seemed to be low and about on par with the original Google Glass units.
The device itself was a bit warm and the additional display unit added some bulk, but these weren't immediate deal breakers. The design was still ergonomic and seemed like something that you wouldn't have an issue wearing all-day long.
This is definitely an early concept, but the fact that Lenovo are showing off demo units here means that they are serious about the ideas presented in the Magic View. If additional development can solve some of the heat issues, it seems like this would be a feature that doesn't detract from the core use of the device and can provide a potentially value new interaction method.

Tagged: wearable, tech world, smartwatch, smartphone, smart cast, magic view, lenovo tech world, Lenovo, concept
Today at the Lenovo Tech World keynote presentation, Lenovo CTO Peter Hortensius took the opportunity to show some of the far reaching concepts for smartphones and smartwatches.
The Magic View smartwatch is a stylish, round smartwatch reminiscent of the Moto 360 that seems from the concept renderings to be based around Android Wear. However, the uniqueness comes from what Lenovo is claiming makes it the only smartwatch with two screens.
Optical reflection is used inside of a portion of the strap in order to project a second “virtual interactive display” more than 20 times larger than the integrated display. This is made possible through Lenovo-designed silicon aimed at miniaturizing the components for this type of projection while maintaining the same performance.
Lenovo claims this secondary screen will be useful for things like maps, as well as photo and video viewing, but it be remains to be seen if users would favor a virtual display like this over simply using their existing smartphone display. Privacy is also a big part of what Lenovo is pitching with the Magic View. Since users must place the lens portion next to their eye, other people in the same area cannot look over their shoulders and view potientially sensitive information.
The Lenovo Smart Cast concept plays on a similar idea as the Magic View. Through the use of a build in laser projector, as well as specialized sensors, Lenovo aims at allowing users to project a large virtual touch screen onto tabletop surfaces.
With the use of infrared sensors, users can touch the surface underneath the projection and interact just as if it were a physical display. Lenovo points towards this being useful for such applications as virtual keyboards in productivity apps, or even for media control of projected movies and light gaming such as Fruit Ninja.
The projected display is also independent of the smartphone display, allowing things such as two separate views for video chatting applications.
It remains to be seen if these concepts will ever actually make it into production devices, and if those devices will ever hit North America, but it's always interesting to see what R&D divisions of large companies like Lenovo are up to.

Tagged: windows 10, reachit, microsoft, Lenovo, cortana
Yesterday during briefings at Lenovo’s North Campus just outside of Beijing, the Contextual Computing group took the opportunity to discuss their unique integration of a technology called REACHit with Cortana on Windows 10.
REACHit is an indexing program that Lenovo has developed which is aimed at helping users find their documents among many different services and contexts. Once you authenticate REACHit with your accounts such as Dropbox, Box.net, Google Drive, or your local computers, Lenovo makes an index of the files which you keep there to help you more easily locate what you are looking for.
The most unique feature of REACHit comes in how you issue a search query. Lenovo has developed multiple contexts which they think will be useful in locating files, such as File Type, File Actions, Location, Calendar Events, and time frames. They are indexing the files you give them access to for these specific prompts, and hoping to present them in a more useful fashion.
One of the examples we were walked through involved the prompt, “Where is the presentation I was working on at Starbucks last week?”. In this case, Lenovo is looking at the file types (PPT), whether or not a file was Saved/Opened, the geolocation which this occurred at, and the time frame at which these operations took place.
We didn’t see a live demo of these searches working, and haven’t had hands-on time with the software yet so it’s hard to say if Lenovo has succeeded at their goal, but the technology seems like an interesting solution to a common problem.
There are also security concerns about giving Lenovo access to all of your files, and letting them build an index your metadata. We have been told there is encryption being handled on Lenovo’s server side, but they couldn’t get into any further details about this.
REACHit at this point is purely integrated with Microsoft’s Cortana in Windows 10, and there is no other option for running a search or external API access. Lenovo expects REACHit to be available at the Windows 10 launch for Lenovo machines only, and is currently opening sign-ups for the private beta at Cortanareachit.com

Tagged: overwatch, E3 2015, E3, blizzard
Various companies have begun teasing what we might see at this year's E3 expo. Blizzard has not historically had a big presence at the event, though. With the size and scope of Blizzcon, the company usually saves it announcements for then. In fact, I cannot think of a single, non-trivial thing that Blizzard did at E3 since the expo downsized after E3 2006.
This year, on the other hand, Blizzard will be present at AMD and PC Gamer's E3 show. The recent Overwatch previews could be leading up to this event, which takes place three weeks from yesterday. The recent video that I embed above, Tracer, is pretty interesting too. It shows how useful a light assault player could be if they don't obey the space-time continuum. The last two-thirds of the video show off an impressive kill streak.
Again, expect more E3 coverage leading up to the Expo on June 16th.

Even though COMPUTEX 2015 doesn't begin for almost a week, the organizers have presented their “Best Choice Award”. Many devices won from a variety of categories, such as the NVIDIA SHIELD Tablet and the 19” Stainless Fanless Industrial Panel PC from Wincomm Corporation. Being COMPUTEX, they appreciate PC gaming and overclocking, which led to MSI winning a pair of awards for its X99-based motherboards.
The MSI X99A GAMING 9 ACK motherboard won the Best Choice Golden Award for Gaming and Entertainment because of its Streaming Engine Module. This feature uses an AVerMedia encoder to stream 60 megabit, 1080p, H.264 gaming video over the internet, to compensate for the lack of Intel Quicksync on Haswell-E. I have never seen it in action, but it seems to have interested the judges. MSI's second award is for the MSI X99A XPOWER AC motherboard, which won the Best Choice Award for Computer and System because of its overclocking capability.
COMPUTEX starts on June 2nd in Taiwan, which is next week, but expect more news before then.

Today at their Tech World event in Beijing, Lenovo is taking the opportunity to announce some new mainstream notebook options.
First off, we have simply the Lenovo Z41 and Z51. The 14-inch Z41 and 15.6-inch Z51 aim to refresh the previous Z40 and Z50 with Broadwell CPUs as well as new AMD discrete GPU options.
Lenovo is using the Broadwell-U class of CPUs here as you would find in ultra books, so don't expect a CPU powerhouse, but for productivity style tasks these machines should hit the sweet spot of Price vs Performance with a starting price of $549 for the base Z51.
Paired with the new AMD R9-M360 (Z41) or M375 (Z51) these notebooks should also be able to play mainstream titles on the integrated 1080p display while coming in just over $800.
Lenovo also announced a low-cost entry into the ideapad line utilizing Intel's BayTrail-M processors. The ideapad 100 is available in both 14-inch and 15-inch variants and seems to be aimed at the low-cost Chromebook market.
Starting at $249, the ideapad 100 seems like it will be a good option for users looking for a secondary option for basic web browsing and office tasks.
Stay tuned for more from Lenovo's Tech World Event this week!

Tagged: nvidia, DIGITS
At GTC, NVIDIA announced a new device called the DIGITS DevBox:
The DIGITS DevBox is a device that data scientists can purchase and install locally. Plugged into a single electrical outlet, this modified Corsair Air 540 case equipped with quad TITAN X (reviewed here) GPUs can crank out 28 TeraFLOPS of compute power. The installed CPU is a Haswell-E 5930K, and the system is rated to draw 1300W of power. NVIDIA is building these in-house as the expected volume is low, with these units likely going to universities and small compute research firms.
Why would you want such compute power?
DIGITS is a software package available from NVIDIA. Its purpose is to act as a tool for data scientists to manipulate deep learning environments (neural networks). This package, running on a DIGITS DevBox, will give much more compute power capability to scientists who need it for their work. Getting this tech in the hands of more scientists will accelerate this technology and lead to what NVIDIA hopes will be a ‘Big Bang’ in this emerging GPU-compute-heavy field.
Ryan interviewed the lead developer of DIGITS in the video below. This offers a great explanation (and example) of what this deep learning stuff is all about:

At the recent Game Developer Conference and Mobile World Congress events, Valve had a demo for HTC's Vive VR system that was based in the Portal universe. The headset is combined with two controllers, one for each hand, which sound like a cross between Valve's Steam Controller and the Razer Hydra.
When HTC briefed journalists about the technology, they brought a few examples for use with their prototype. C|Net described three: a little demo where you could paint with the controllers in a virtual space, an aquarium where you stand on a sunken pirate ship and can look at a gigantic blue whale float overhead, and a Portal-based demo that is embedded above. I also found “The Gallery” demo online, but I am not sure where it was presented (if anywhere).
Beyond VR, the Source 2 engine, which powers the Portal experience, looks good. The devices looked very intricate and full of detail. Granted, it is a lot easier to control performance when you are dealing with tight corridors or isolated rooms. The lighting also seems spot on, although it is hard to tell whether this capability is dynamic or precomputed.
The HTC Vive developer kit is coming soon, before a consumer launch in the Autumn.

Possibly the most important feature of upcoming graphics APIs, albeit the least interesting for enthusiasts, is how much easier driver development will become. So many decisions and tasks that once laid on the shoulders of AMD, Intel, NVIDIA, and the rest will now be given to game developers or made obsolete. Of course, you might think that game developers would oppose this burden, but (from what I understand) it is a weight they already bear, just when dealing with the symptoms instead of the root problem.
This also helps other hardware vendors become competitive. Imagination Technologies is definitely not new to the field. Their graphics powers the PlayStation Vita, many earlier Intel graphics processors, and the last couple of iPhones. Despite how abrupt the API came about, they have a proof of concept driver that was present at GDC. The unfinished driver was running an OpenGL ES 3.0 demo that was converted to the Vulkan API.
A screenshot of the CPU usage was also provided, which is admittedly heavily cropped and hard to read. The one on the left claims 1.2% CPU load, with a fairly flat curve, while the one on the right claims 5% and seems to waggle more. Granted, the wobble could be partially explained by differences in the time they chose to profile.
According to Tom's Hardware, source code will be released “in the near future”.

I am not quite sure if the Game Developers Conference led to this video being released, or if it was just a coincidence. This is the sole work of Alexander Dracott, a visual effects, lighting, and shader artist who has been employed at Sucker Punch and Sony Online Entertainment. He works for a studio in Bellevue, Washington, USA doing VR demos, which sounds like Valve but is probably someone else entirely.
Basically, it is a forest scene that is rendered in Unreal Engine 4. It is convincing, despite a little macroblocking from Vimeo compression (or its source). Even the falling leaves cast appropriate shadows. Granted, he never mentions his computer's specifications, which could make a difference in how many features he could get away with enabling. Either way, the art would even be amazing in a non-realtime scene, let alone Unreal Engine 4.
A couple of days later, he posted pictures of the same scene in an autumn time frame (same link). I guess that I should keep coming back to this thread, just in case it gets a Winter update or something. Awesome work!

During his keynote speech, Phil Spencer of Microsoft announced a wireless adapter for PC. It can apparently be used to connect any wireless Xbox One peripheral on Windows 10. If you watch the presentation, the statement occurred at about 36 minutes and 30 seconds in. It was just a brief acknowledgement of its existence this year.
A similar device existed for the Xbox 360, pictured above, and I used it heavily with controller-friendly games (until the adapter died abruptly). I was not a fan of the directional pad, of course, but the rest of the controller suited the games that I play without a mouse and keyboard. I also used the adapter with the Xbox 360 wireless headset, which was surprisingly good (especially at removing speaker noise).
On the same day, Neowin acquired a leak that claims the company is looking to create a new Xbox One controller. They expect that, if the project doesn't get killed internally, we will see the new controller at E3 2015 in June. The design is supposed to focus on first person shooters and driving titles, but nothing else is known about it. We'll see.
