Tagged: raptr, pc game streaming

Raptr seems to be gaining in popularity. Total playtime recorded by the online service was up 15% month-over-month, from May to June. The software is made up of a few features that are designed to make the lives of PC gamers easier and better, ranging from optimizing game settings to recording gameplay. If you have used a recent version of GeForce Experience, then you probably have a good idea of what Raptr does.

Today, Raptr has announced a new, major update. The version's headlining feature is hardware accelerated video recording, and streaming, for both AMD and NVIDIA GPUs. Raptr claims that their method leads to basically no performance lost, regardless of which GPU vendor is used. Up to 20 minutes of previous gameplay can be recorded after it happened and video of unlimited length can be streamed on demand.

Notice the recording overlay in the top left.

The other, major feature of this version is enhanced sharing of said videos. They can be uploaded to Raptr.com and shared to Facebook and Twitter, complete with hashtags (#BecauseYolo?)

"One of the machines that didn’t make it into his collection until recently was a Commodore 64 with Datasette and 1541 drive. With no tapes and a 1541 disk drive that required significant restoration, he looked at other devices to load programs onto his C64."

Tagged: shield tablet, shield, nvidia

Just a small note to continue with our SHIELD Tablet coverage. It turns out that the $299 (16GB) SHIELD Tablet, its cover, and its wireless controller are all available for pre-order on Amazon. The unit will actually be available on July 29th, but we were not aware that pre-orders would be possible until now.

nvidia-shield-tablet-front.jpg

While Ryan wrote a preview for the SHIELD Tablet, he is not giving a final word until he gets it into his lab and is capable of giving a full review. Also, we do not know how many units will be available. Whether you should pre-order, or wait for Ryan's final word, is up to you.

Thanks to our fans for alerting us of this availabilty in the IRC during TWiCH.

Rumor: NVIDIA GeForce 800-Series Is 28nm in Oct/Nov.

Subject: General Tech, Graphics Cards | July 24, 2014 - 04:32 PM |
Tagged: nvidia, gtx 880

Many of our readers were hoping to drop one (or more) Maxwell-based GPUs in their system for use with their 4K monitors, 3D, or whatever else they need performance for. That has not happened, nor do we even know, for sure, when it will. The latest rumors claim that the NVIDIA GeForce GTX 870 and 880 desktop GPUs will arrive in October or November. More interesting, it is expected to be based on GM204 at the current, 28nm process.

nvidia-pascal-roadmap.jpg

The recent GPU roadmap, as of GTC 2014

NVIDIA has not commented on the delay, at least that I know of, but we can tell something is up from their significantly different roadmap. We can also make a fairly confident guess, by paying attention to the industry as a whole. TSMC has been struggling to keep up with 28nm production, having increased wait times by six extra weeks in May, according to Digitimes, and whatever 20nm capacity they had was reportedly gobbled up by Apple until just recently. At around the same time, NVIDIA inserted Pascal between Maxwell and Volta with 3D memory, NVLink, and some unified memory architecture (which I don't believe they yet elaborated on).

The previous roadmap. (Source: Anandtech)

And, if this rumor is true, Maxwell was pushed from 20nm to a wholly 28nm architecture. It was originally supposed to be host of unified virtual memory, not Pascal. If I had to make a safe guess, I would assume that NVIDIA needed to redesign their chip to 28nm and, especially with the extra delays at TSMC, cannot get the volume they need until Autumn.

Lastly, going by the launch of the 750ti, Maxwell will basically be a cleaned-up Kepler architecture. Its compute units were shifted into power-of-two partitions, reducing die area for scheduling logic (and so forth). NVIDIA has been known to stash a few features into each generation, sometimes revealing them well after retail availability, so that is not to say that Maxwell will be "a more efficient Kepler".

I expect its fundamental architecture should be pretty close, though.

I Guess Battlefield Isn't Annualized - Hardline Delayed to 2015

Tagged: battlefield, battlefield hardline

Yeah, I will admit it, the title is a joke. EA can annualize Battlefield as much as they like (as long as quality does not drop). The point is that Battlefield: Hardline has been delayed until early 2015. It is only a few extra months, which haters can still it to be a yearly release schedule, but it will not be under your tree, at least not this year.

battlefield-hardline.jpg

Apparently, release dates are not hard lines...

DICE (not Visceral??) made the announcement on their Battlefield blog. Three areas will be worked on with the free time: Multiplayer "Innovation", Single Player Story "Depth", and Stability. I could remember a time, prior to ubiquitous internet access, that "stability" was a certification requirement, not a stretch goal. That was also a time that some platform owners could push you out of their first-party release windows to increase their own sales. I guess, give and take?

Battlefield: Hardline is now set for a launch in early 2015. That should be one less distraction from your Grand Theft Auto V PC experience.

The new netbook?

Tagged: Intel, microsoft, netbook, Bay Trail

According to DigiTimes we may see a resurgence of netbooks, this time powered by Bay Trail which will make them far more usable than the original generation.  There are three postulated tiers, the $200-250 range of 10.1-15.6" models and $250-400 or $400-600 in 11.6-17.3" which will make them larger in size than the original generation which failed to attract many consumers.  They are currently scheduled to ship with Bay Trail-M with future models likely to have Braswell inside in a mix of transformer style 2 in 1's with touchscreens and more traditional laptop designs.  You can expect to see a maximum thickness of 25mm and a mix of HDD and SSD storage on these and we can only hope that the estimated pricing is more accurate than the pricing on Ultrabooks turned out to be.

pr_toshiba_netbook_f.jpg

"For the US$199-249 notebooks, Intel and Microsoft's specification preferences are 10.1- to 15.6-inch clamshell non-touchscreen models using Intel's Bay Trail-M series processors or upcoming Braswell-based processors, which are set to release in the second quarter of 2015."

Xiaomi Launches Mi4 Smartphone In China

Subject: General Tech | July 23, 2014 - 10:40 AM |
Tagged: xiaomi, snapdragon 801, smartphone, mobile, LTE, Android 4.4.2

Yesterday, Xiaomi revealed a powerful smartphone called the Mi4 that looks to give the unlocked OnePlus One a run for its money. The new smartphone is launching first in China with an international version coming in the future. 

Xiaomi Mi4 Smartphone_angled.jpg

The Xiaomi Mi4 features a 5" 1080p IPS LCD display, 13MP rear camera, and 8MP webcam. A metal band surrounds the outside edges of the phone while a stainless steel frame adds rigidity and protection for the internal hardware. The other bits of the case are plastic, however likely due to weight and signal reception concerns. There is a removable back cover that is available in several different designs and colors. The Mi4 is slightly bulkier than its predecessor at 0.35-inches thick and 149 grams.

Xiaomi Mi4 Android Smartphone Breakout.png

Internally, the Mi4 uses a Qualcomm Snapdragon 801 SoC with four Krait 400 CPU cores clocked at 2.5GHz and an Adreno 330 GPU. Further, the smartphone features 3GB of RAM and either 16GB or 64GB of internal storage. It is powered by a 3,080 mAh battery which should provide ample battery life. Wireless connectivity includes dual band 802.11b/g/n/ac Wi-Fi, Bluetooth 4.0, NFC, 3G, and LTE. The WCDMA version of the smartphone will be available first with a CDMA version coming next month, and a 4G LTE capable device coming in September.

The smartphone runs Android 4.4.2 with a highly customized MIUI5 user interface. An updated version of the UI, called MIUI6 is reportedly coming in August, but it is unclear how soon Mi4 users can expect an upgrade.

Xiaomi Mi4 Smartphone.jpg

The Xiaomi Mi4 will be available on July 29 for 1,999 Yuan ($322 USD) for the 16GB version and 2,499 Yuan ($403) for the 64GB version. Initially, it will be 3G only, but a 4G LTE capable version of the smartphone is coming in September (presumably for the same price). Even further out, an unlocked international version is said to be available for purchase in the future.

In all, the Mi4 looks to be a decent phone with enough design tweaks and hardware oomph to give existing high end smartphones a run for their money. You do sacrifice micro SD card support and stock Android, but if you can live with that and are in the target market (or can wait for an international version) it is worth keeping an eye on!

Dropbox for Business; to encrypt or not to encrypt?

Subject: General Tech | July 23, 2014 - 10:08 AM |
Tagged: dropbox, data privacy, encryption

Dropbox has faced many questions about the privacy of the data held on their service after modified links were shown to successfully connect to private portions of accounts as well as their ability to hand over all your content in readable form to authorities.  While for many the lack of encryption is not much of a concern, businesses cannot afford to be so lax with potentially valuable client data stored on Dropbox.  This use of Dropbox by businesses is far more common than you may think and may expand with the announcement of Dropbox for Business and the expanded services available for this new service.

For those with security concerns about storing unencrypted data on Dropbox it would seem that the recommendation is to use third party client side encryption software.  That does mean that the new search features will not work as Dropbox will be unable to index files as they pointed out to The Inquirer and other media.  Dropbox does have a decent reputation for protecting the data they store but for those intending to store proprietary data on the cloud the balance between ease of use and privacy should be considered before moving to any cloud storage provider.

One year later and the Nvidia Shield becomes a Tablet

Shame on you if you skipped Ryan's review of the new Shield, for those that have and are looking for a second opinion you can check out The Tech Report and other links below the fold.  To quickly recap the controller is now optional but you can connect up to 4 simultaneously for group gaming, the built in 8" IPS display is capable of 1920x1200 and you can output video to an external monitor at 1080p.  The 192 shader processors on the Tegra K1 SoC inside should have no problems with fast paced action at these resolutions and at launch there are almost a dozen games optimized for the K1.  The focus on gaming performance is obvious but the inclusion of DirectStylus 2 for those who want to use the tablet for creating art adds an interesting extra feature to this tablet, especially if it will work with NVIDIA's ShadowPlay streaming technology as live broadcasts of artists drawing has become quite popular in some crowds.  It will be very interesting to see this tablet compete against consoles and the soon to arrive Steamboxes.

"Just under a year since the release of the Shield Portable, Nvidia has announced a second member of the Shield family. As expected, it's the Shield Tablet, an Android slate with an emphasis on gaming. Like the Shield Portable before it, the Shield Tablet will sell direct from Nvidia, not from a partner company. The Shield Tablet extends Nvidia's Android gaming focus to a new form factor, making it one of the first tablets anywhere with a fairly pure gaming mission."

At some time in the very near future, if this naming trend does not reverse itself, the wraparound portion of headphones will have to be enlarged to be able to display the entire brand name legibly.  The latest lengthy moniker is the Turtle Beach Ear Force Z SEVEN Gaming Headset with removable unidirectional microphone and Audio Control Unit.  The mic is self explanatory but the ACU is an external sound card with voice morphing and headphone equalizer presets and has outputs for PC, Mac and Xbox; it is not a booster amp.  Overall Legit Reviews found this headset to be a great generalist but not as good for specific usage such as taking advantage of positional in a game.  Read on to see if they peak your interest.

turtle_beach_z_seven_05-645x527.jpg

"Turtle Beach is perhaps a name better known amongst console gamers since you can easily find their Ear Force lineup of headsets somewhere close to where the boxed console games are in certain stores. Most Turtle Beach Ear Force headsets are compatible with computers or any electronic device with a 3.5 mm jack nonetheless because most gamers or even most people make due with one set of headphones for all their devices. The Turtle Beach Z SEVEN we have for review is actually part of a much larger family of SEVEN headsets. Read on to find out more about it!"

Metro could soon be retro; Windows 8.1's final patch

Tagged: win 8.1, microsoft

Windows 8 and 8.1, non-update 1 version, are already essentially EoL with only limited support offered those rare businesses which deployed the new version of Windows.  If the rumours that The Inquirer have been hearing are correct then Service Pack Update 2 will be arrive on August 12th and herald the end of Windows 8.1 updates a mere two years after release.  Win 8.1 U2 will probably be with us for a while, the release of Win 9 is rumoured to be about 12 months away still and the Metro version is likely to appear on mobile devices for a while now.  It is extremely unlikely that the Start Menu will be included in this update but for those who are running Win 8.1 U1 it is worth considering turning off Automatic Updates if you are worried about encountering boot issues similar to what happened during the initial push of 8.1 U1.

In Europe, NVIDIA set up a simple, official page. Its title is "THE ULTIMATE IS COMING | NVIDIA". On it are the words, "The Ultimate Is Coming" as well as a countdown to 9 AM EDT on Tuesday, July 22nd. At the same time, North Americans get "Ultimate Quest", a text adventure game which ends on -- surprise -- Tuesday with a giveaway of "something big" for the first players who finish.

All images credit: Videocardz (and they have more).

What is it? It is very likely the rumored SHIELD tablet, especially considering Videocardz has convincing slides which are definitely made in NVIDIA's style. What made SHIELD so unique was its controller form factor (and NVIDIA's software support). According to the slides, the controller will now be a wireless accessory to the base tablet. What will come standard is a stylus, the "DirectStylus 2 with 3D Paint". This seems like an odd addition, unless they have already planned use cases.

Allegedly leaked slide - Not Official!

NVIDIA-SHIELD-Tablet-5.jpg

As for the tablet? The slides claim Tegra K1, 2GB of RAM, 1920x1200 display, 5MP (HDR) front and rear cameras, and a MicroSD card slot. Previously, leaks suggested a 640x480 front-facing camera, which did not make sense to me. With the original SHIELD lacking a camera, it seemed very odd to relaunch with a bad one. 5MP, especially if it is a good sensor, is much more reasonable (especially for the front-facing one).

Allegedly leaked slide - Not Official!

The leaks also suggest interesting price points, especially for such a powerful tablet. These details can change at a moment's notice, though, so I won't really acknowledge it (apart from embedding the slide below). They do seem to be targeting the end of the month for North America, or middle August for Europe, which is a very quick launch. Then again, it is ready enough to be a prize for a contest which ends on Tuesday.

Tiago Sousa was "Lead R&D Graphics Engineer" at Crytek, according to his now defunct Twitter account, "@CRYTEK_TIAGO". According to his new Twitter account, "@idSoftwareTiago", he will be joining id Software to help with DOOM and idTech 6.

A little less DOOM and gloom.

I find this more interesting because idTech 5 has not exactly seen much usage, outside of RAGE. Wolfenstein: The New Order was also released on the technology, two months ago. There is one other game planned -- and that is it. Sure, RAGE is almost three years old and the engine was first revealed in 2007, making it seven-year-old technology, basically. Still, that is a significant investment to see basically no return on, especially considering that its sales figures were not too impressive (Steam and other digital delivery services excluded).

I also cannot tell if this looks positive for id, after mixed comments from current and former employees (or people who claim to be), or bad for Crytek. The latter company was rumored to be hurting for cash since 2011 and saw the departure of many employees. I expect that there will be more to this story in the coming months and years.

Apparently, some hardware sites got their hands on an NVIDIA driver listing with several new product codes. They claim thirteen N16(P/E) chips are listed (although I count twelve (??)). While I do not have much knowledge of NVIDIA's internal product structure, the GeForce GTX 880M, based on Kepler, is apparently listed as N15E.

Things have changed a lot since this presentation.

These new parts will allegedly be based on the second-generation Maxwell architecture. Also, the source believes that these new GPUs will in the GeForce GTX 800-series, possibly with the MX suffix that was last seen in October 2012 with the GeForce GTX 680MX. Of course, being a long-time PC gamer, the MX suffix does not exactly ring positive with my memory. It used to be the Ti-line that you wanted, and the MX-line that you could afford. But who am I kidding? None of that is relevant these days. Get off my lawn.

Intel AVX-512 Expanded

Subject: General Tech, Graphics Cards, Processors | July 19, 2014 - 12:05 AM |
Tagged: Xeon Phi, xeon, Intel, avx-512, avx

It is difficult to know what is actually new information in this Intel blog post, but it is interesting none-the-less. Its topic is the AVX-512 extension to x86, designed for Xeon and Xeon Phi processors and co-processors. Basically, last year, Intel announced "Foundation", the minimum support level for AVX-512, as well as Conflict Detection, Exponential and Reciprocal, and Prefetch, which are optional. This, earlier blog post was very much focused on Xeon Phi, but it acknowledged that the instructions will make their way to standard, CPU-like Xeons at around the same time.

Intel_Xeon_Phi_Family.jpg

This year's blog post brings in a bit more information, especially for common Xeons. While all AVX-512-supporting processors (and co-processors) will support "AVX-512 Foundation", the instruction set extensions are a bit more scattered.

 
Xeon
Processors
Xeon Phi
Processors
Xeon Phi
Coprocessors (AIBs)
Foundation Instructions Yes Yes Yes
Conflict Detection Instructions Yes Yes Yes
Exponential and Reciprocal Instructions No Yes Yes
Prefetch Instructions No Yes Yes
Byte and Word Instructions Yes No No
Doubleword and Quadword Instructions Yes No No
Vector Length Extensions Yes No No

Source: Intel AVX-512 Blog Post (and my understanding thereof).

So why do we care? Simply put: speed. Vectorization, the purpose of AVX-512, has similar benefits to multiple cores. It is not as flexible as having multiple, unique, independent cores, but it is easier to implement (and works just fine with having multiple cores, too). For an example: imagine that you have to multiply two colors together. The direct way to do it is multiply red with red, green with green, blue with blue, and alpha with alpha. AMD's 3DNow! and, later, Intel's SSE included instructions to multiply two, four-component vectors together. This reduces four similar instructions into a single operating between wider registers.

Smart compilers (and programmers, although that is becoming less common as compilers are pretty good, especially when they are not fighting developers) are able to pack seemingly unrelated data together, too, if they undergo similar instructions. AVX-512 allows for sixteen 32-bit pieces of data to be worked on at the same time. If your pixel only has four, single-precision RGBA data values, but you are looping through 2 million pixels, do four pixels at a time (16 components).

For the record, I basically just described "SIMD" (single instruction, multiple data) as a whole.

This theory is part of how GPUs became so powerful at certain tasks. They are capable of pushing a lot of data because they can exploit similarities. If your task is full of similar problems, they can just churn through tonnes of data. CPUs have been doing these tricks, too, just without compromising what they do well.

AMD Posts Financial Results for Q2 2014

Subject: General Tech | July 17, 2014 - 08:37 PM |
Tagged: quarterly earnings, GCN, financial results, APU, amd

Today, AMD posted financial results for its second quarter of 2014. The company posted quarterly revenue of $1.44 billion, operating income of $63 million, and ultimately a net loss of $36 million (or $0.05 loss per share). The results are an improvement over both the previous quarter and a marked improvement over the same quarter last year. 

The chart below compares the second quarter results to the previous quarter (Q1'14) and the same quarter last year (Q2'13). AMD saw increased revenue and operating income, but a higher net loss versus last quarter. Unfortunately, AMD is still saddled with a great deal of debt, which actually increased from 2.14 billion in Q1 2014 to $2.21 billion at the end of the second quarter. 

  QoQ   YoY  
  Q2 2014 Q1 2014 Q2 2014 Q2 2013
Revenue $1.44 Billion $1.40 Billion $1.44 Billion $1.16 Billion
Operating Income $63 Million $49 Million $63 Million ($29 Million)
Net Profit/(Loss) ($36 Million) ($20 Million) ($36 Million) ($74 Million)

The Computing Solutions division saw increased revenue of 1% over last quarter, but revenue fell 20% year over year due to fewer chips being sold.

On the bright side, the Graphics and Visual Solutions group saw quarterly revenue increase by 5% over last quarter and 141% YoY. The massive YoY increase is due, in part, to AMD's Semi-Custom Business unit and the SoCs that have come out of there (including the chips used in the latest gaming consoles).

Further, the company is currently sourcing 50% of its wafers from Global Foundries.

“Our transformation strategy is on track and we expect to deliver full year non-GAAP profitability and year-over-year revenue growth.  We continue to strengthen our business model and shape AMD into a more agile company offering differentiated solutions for a diverse set of markets.”

-AMD CEO Rory Reed

AMD expects to see third quarter revenue increase by 2% (plus or minus 3%). Following next quarter, AMD will begin production of its Seattle ARM processors. Perhaps even more interesting will be 2016 when AMD is slated to introduce new x86 and GCN processors on a 20nm process. 

The company is working towards being more efficient and profitable, and the end-of-year results will be interesting to see.

According to the tweet from Ton Roosendaal, Chairman of the Blender Foundation, this is intended to support FBX development, which is becoming the industry standard method of importing and exporting 3D models, skeletons, animations, and so forth. It is also for "epic-game-style navigation controls" (not sure what this is -- Unreal Editor-style controls maybe??)

FBX support would definitely be a welcome area of development. It exists, but not at the level of other 3D applications, because those could link directly to Autodesk's library. The format is owned by Autodesk after they acquired Kaydara in 2006. Its closed-source SDK was put under a license that was incompatible with Blender and its public documentation was non-existent. Since then, the Blender community has been working on reverse-engineered support. They have come a long way, the exporting from Blender and importing into Unreal Engine 4 is apparently reasonable, today. Of course, with Epic's focus on the indie developer, $13,500 seems like a good investment to help it continue.

Beyond its status as the default import format into Unreal Engine 4.x, FBX is also standard in many different modeling applications. While it is fairly easy to move around most base, polygonal geometry (and UVs to properly apply materials to them) from suite to suite, the same cannot be said for animation data, and so forth. FBX was designed to be a single pipeline for all of that.

Hopefully, Blender can become a first-class citizen.
