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.

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.

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.

At the Game Developers Conference, Valve has formally announced the Source 2 engine and that it would be free for content developers. At the same time, they committed to releasing a version of it that is compatible with Vulkan, the graphics API from the Khronos Group that we have been talking about a lot over the last couple of days. Of course though, free can mean many things. As it turns out, there is one string attached: the game must be made available on Steam at launch. It can be available elsewhere too, but Steam must be one of the launch retailers.
I do wonder what will happen if someone makes a title that Steam refuses to publish. Of course, the natural thought is “What if Valve refuses to publish for content reasons?” That is an interesting thought, and maturity is one area that many other engines (like Unreal) do not restrict, but it is not the only concern (and Gabe Newell is quite laissez-faire with his -- albeit loosely defined -- content guidelines). What if your content simply does not make it on Steam? For instance, with is someone creates a title in Source 2 and has a failed attempt at Greenlight because it was unpopular? Are you then unable to publish your content through alternative channels, too? This seems like something that Valve will need to provide a little clarification on.
Try as I might, I could not find a release date for Source 2, however. It will arrive when it does.

Tagged: GDC, gdc 15, nvidia, epic games, ue4, unreal engine 4, PhysX, apex
NVIDIA and Epic Games have just announced that Unreal Engine 4 developers can view and modify the source of PhysX. This also includes the source for APEX, which is NVIDIA's cloth and destruction library. It does not include any of the other libraries that are under the GameWorks banner, but Unreal Engine 4 does not use them anyway.
This might even mean that good developers can write their own support for third-party platforms, like OpenCL. That would probably be a painful process, but it should be possible now. Of course, that support would only extend to their personal title, and anyone who they share their branch with.
If you are having trouble finding it, you will need to switch to a branch that has been updated to PhysX 3.3.3 with source, which is currently just “Master”. “Promoted” and earlier seem to be back at PhysX 3.3.2, which is still binary-only. It will probably take a few months to trickle down to an official release. If you are still unable to find it, even though you are on the “Master” branch, the path to NVIDIA's source code is: “Unreal Engine/Engine/Source/ThirdParty/PhysX/”. From there you can check out the various subdirectories for PhysX and APEX.
NVIDIA will be monitoring pull requests sent to that area of Unreal Engine. Enhancements might make it back upstream to PhysX proper, which would then be included in future versions of Unreal Engine and anywhere else that PhysX is used.
In other news, Unreal Engine 4 is now free of its subscription. The only time Epic will ask for money is when you ship a game and royalties are due. This is currently 5% of gross revenue, with the first $3000 (per product, per calendar quarter) exempt. This means that you can make legitimately free (no price, no ads, no subscription, no microtransactions, no Skylander figurines, etc.) game in UE4 for free now!

Tagged: vulkan, Mantle, Khronos, glnext, gdc 15, GDC, amd
Neil Trevett, the current president of Khronos Group and a vice president at NVIDIA, made an on-the-record statement to acknowledge the start of the Vulkan API. The quote came to me via Ryan, but I think it is a copy-paste of an email, so it should be verbatim.
Many companies have made great contributions to Vulkan, including AMD who contributed Mantle. Being able to start with the Mantle design definitely helped us get rolling quickly – but there has been a lot of design iteration, not the least making sure that Vulkan can run across many different GPU architectures. Vulkan is definitely a working group design now.
So in short, the Vulkan API was definitely started with Mantle and grew from there as more stakeholders added their opinion. Vulkan is obviously different than Mantle in significant ways now, such as its use of SPIR-V for its shading language (rather than HLSL). To see a bit more information, check out our article on the announcement.
Update: AMD has released a statement independently, but related to Mantle's role in Vulkan

HP announced their updated Spectre x360 at Mobile World Congress. Like the Lenovo Yoga, it has a hinge that flips the entire way around, allowing the laptop to function as a 13.3-inch tablet with a 1080p, IPS display. There are two stages between “tablet” and “laptop”, which are “stand” and “tent”. They are basically ways to prop up the touch screen while hiding the keyboard behind (or under) the unit. The stand mode is better for hands-free operation because it has a flat contact surface to rest upon, while the tent mode is probably more sturdy for touch (albeit rests on two rims). The chassis is entirely milled aluminum, except the screen and things like that of course.
The real story is the introduction of Core i-level Broadwell. The 12.5-hour battery listing in a relatively thin form-factor can be attributed to the low power requirements of the CPU and GPU, as well as its SSD (128GB, 256GB, or 512GB). RAM comes in two sizes, 4GB or 8GB, which will depend slightly on the chosen processor SKU.
Prices start at $899 and most variants are available now at HP's website.
