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.

eSports? Did someone say sports? ESPN is there. DOTA 2 is one of the most popular PC Games, #2 in Raptr's listing, and currently the most played Valve game (by more than a factor of two over Counter-Strike: GO). The International 2014 is their fourth multi-million dollar tournament. This year's prize pool of almost $11 million USD.

NVIDIA Preparing GeForce 800M (Laptop) Maxwell GPUs?

Subject: General Tech, Graphics Cards, Mobile | July 19, 2014 - 12:29 AM |
Tagged: nvidia, geforce, maxwell, mobile gpu, mobile graphics

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.

Epic Games Donates $13,500 to Blender Development Fund

Subject: General Tech | July 17, 2014 - 02:16 PM |
Tagged: open-source, open source, fbx, epic games, Blender

Blender, probably the most popular, open source 3D creation suite (sorry Wings!), was given a healthy donation of $13,500 USD by Epic Games. 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.

Apple and IBM; together again

Ah, sweet nostalgia.  It seems like only a short while ago that Apple was saved by IBM, and Motorola, granting access to the PowerPC chips which were near the top of the field back in 1991.  The Motorola 68K was falling behind the Pentium MMX chips in PCs and Apple needed some way to compete in the market and the 200-MHz 603e PowerPC was the answer.  Now history is repeating itself with a partnership between IBM and Apple to bring iPhone apps to the enterprise, with apps specifically for enterprise environments as well as updates to existing apps to make them more enterprise friendly.  Read up on your history, or refresh your memories of times gone by as well as what this partnership will bring in the future on Slashdot.

"Apple and IBM, which just announced partnership to bring iOS and cloud services to enterprises, have helped each other before. IBM played a key role in turning the Macintosh into a successful hardware platform at a point when it — and the company itself — were struggling. Nearly 25 years ago, IBM was a part of an alliance that gave Apple access to PowerPC chips for Macintosh systems that were competitive, if not better performing in some benchmarks, than the processors Intel was producing at the time for Windows PCs."

Tagged: gaming, Mantle, battlefield 4, BF4

Mantle is currently supported by the Nitrous, Frostbite 3 and CRYENGINE engines, and the current official list of released or soon to be released games that support the new API has reached eight AAA titles.  eTeknix lined up three of these games to test, Battlefield 4, Thief and PvZ Garden Warfare to test on an R9 290X paired with both a AMD FX-8350 and an FX-4100.   For BF4 with the Ultra preset, no V-Sync @ 1920 x 1080 both systems saw a noticeable jump in performance and Thief even more so for the FX8350 system.  Check out the full results in their review.

Don't forget to enable your team up with the Fragging Frogs while playing BF4, there is still a screenshot contest going on.

"The biggest claim to fame of this new low-overhead API is its use in EA’s Battlefield 4 blockbuster and the support it has from EA’s famous FrostBite 3 Engine. However, what is all the fuss about? How does Mantle actually perform in practice? Why should you even care about it? These are questions we are hoping to address today."

Google Play Store Could Be Redesigned (Maybe Even Soon)

Tagged: google, google play, Android, android l

If you have looked at Google's recent design ideologies, first announced at Google I/O 2014, you will see them revolve around skeuomorphism in its most basic sense. By that, I do not mean that they want to make it look like a folder, a metal slab, or a radio button. Their concept is that objects should look like physical objects which behave with physical accuracy, even though they are just simulations of light.

Basically, rather than having a panel with a toolbar, buttons, and columns, have a background with a page on it. Interface elements which are affected by that panel are on it, while more global actions are off of it. According to Android Police, who make clear that they do not have leaked builds and readers should not believe anything until/unless it ships, the Google Play Store will be redesigned with this consistent, albeit broad, design metric.

Basically, if you are navigation bar, pack your desk and get out.

If true, when will these land? Anyone's guess. One speculation is that it will be timed with the release of Android "L" in Autumn. Their expectation, however, is that it will be one of many updates Google will make across their products in a rolling pattern. Either way, I think it looks good... albeit similar to many modern websites.

Intel Earnings Report (Q2 2014)

Tagged: quarterly results, quarterly earnings, quarterly, Intel, earnings

Another fiscal quarter brings another Intel earnings report. Once again, they are doing well for themselves as a whole but are struggling to gain a foothold in mobile. In three months, they sold 8.7 billion dollars in PC hardware, of which 3.7 billion was profit. Its mobile division, on the other hand, brought in 51 million USD in revenue, losing 1.1 billion dollars for their efforts. In all, the company is profitable -- by about 3.84 billion USD.

Intel-Swimming-in-Money.jpg

One interesting metric which Intel adds to their chart, and I have yet to notice another company listing this information so prominently, is their number of employees, compared between quarters. Last year, Intel employed about 106,000 people, which increased to 106,300 two quarters ago. Between two quarters ago and this last quarter, that number dropped by 1400, to 104,900 employees, which was about 1.3% of their total workforce. There does not seem to be a reason for this decline (except for Richard Huddy, we know that he went to AMD).

As a final note, Anandtech, when reporting on this story, added a few historical trends near the end. One which caught my attention was the process technology vs. quarter graph, demonstrating their smallest transistor size over the last thirteen-and-a-bit years. We are still slowly approaching 0nm, following an exponential curve as it approaches its asymptote. The width, however, is still fairly regular. It looks like it is getting slightly longer, but not drastically (minus the optical illusion caused by the smaller drops).

SolidRun's New SFF HummingBoard PC Is A Modular Raspberry Pi Clone With Upgradeable ARM Processor

Subject: General Tech | July 15, 2014 - 11:21 PM |
Tagged: solidrun, SFF, Raspberry Pi, iot, i.mx6, Freescale, Cortex A9

SolidRun recently launched a new small form factor PC called the HummingBoard. The new kit is an open source hardware platform that can run a number of open source operating systems. It mimics the physical form factor of the popular Raspberry Pi and as a result is compatible with much of its accessories including cases and add-on boards.

 

The HummingBoard is comprised of two main pieces; the carrier board which hosts all of the I/O ports and pin-outs and the removable microSOM (Silicon on Module) which is a smaller circuit board housing the processor and system memory.

 

SolidRun HummingBoard i2eX Small Computer_Angled.jpg

 

SolidRun currently offers two reference versions of the carrier board, a base design and a higher-end model with beefier I/O. The HummingBoard Carrier is an open source design and the company allows hardware hackers and product developers to use their own custom carrier boards based on the reference design. Each carrier board has a special connector that the Micro SOM plugs into.

 

SolidRun MicroSOM.png

A microSOM (System on a Module) includes the CPU, GPU, RAM, power management, networking, and I/O connectivity hardware.

 

SolidRun currently offers up three microSOMs for use with the HummingBoard. The microSOMs use Freescale i.MX6 series SoCs (PDF), offer up to 1GB of RAM, and host the power management and networking hardware. Depending on the microSOM chosen, users can get a single or dual core CPU paired with a GPU that is at least OpenGL ES 2.0 compatible (the highest end model supports OpenGL ES 2.0 Quad Shader) and video encode/decode hardware units. The HummingBoard is upgrade-able and may support a microSOM with a quad core CPU in the future (a quad core microSOM already exists but is not currently supported by the HummingBoard).

 

SolidRun HummingBoard i2eX.jpg

 

Users can purchase the HummingBoard as a combo (carrier board+processor module) or in individual pieces. Specifically, SolidRun sells the HummingBoard i1, i2, and i2eX. Both the i1 and i2 use the base carrier board while the i2ex uses the pro version. The i1 comes with a single core i.MX6 CPU, GC880 GPU, and 512MB of system memory. The i2 ups the amount of RAM to 1GB and CPU core count by using the Freescale i.MX6 Dual Lite. Finally, the HummingBoad i2eX features a faster clocked dual core CPU (i.MX6 Dual), GC2000 GPU, 1GB of RAM, and significantly more I/O thanks to the higher-end carrier board and processing capabilities.

 

At a minimum, users can expect HDMI video out, 10/100 Ethernet, two powered USB 2.0 ports, a microSD card slot, a coaxial S/PDIF audio output, PWM mono audio, a 2-lane MIPI CSI 2.0 camera interface, and GPIO header. On the high end (HummingBoard Carrier Pro/HummingBoard i2eX/custom configs), the HummingBoard supports Gigabit Ethernet (limited to 470Mbps by the SoC), PCI-E 2.0, mSATA II, two additional USB 2.0 ports (via internal header), stereo audio output, microphone input, an IR receiver, and a Real-Time Clock (RTC) with battery backup.

 

SolidRun is aiming the HummingBoard platform at Internet-of-Things, home automation, and other embedded device developers. I believe that it will also appeal to hobbyists and Linux software developers.

 

SolidRun HummingBoard i2eX_IO.jpg

 

The HummingBoard is rather expandable and is nearly a drop-in alternative to the Raspberry Pi. The open source nature (though, like the Raspberry Pi's BCM2835, the SoC is not fully open source) is nice, and the modular/upgradeable design is sure to appeal to hardware enthusiasts. The HummingBoard starts at $45 and tops out at $99 for the highest end i2eX. It is more expensive than the Raspberry Pi, which is the platform it is most likely to be pitted against, but it features faster hardware (especially the CPU and its ISA: ARMv7 versus ARMv6) and is priced competively with devices like the BeagleBone Black and SolidRun's own CuBox lineup.

 

The small form factor (and "single board PC") market has really ramped up the last few years and it is exciting to watch it all unfold. Stay tuned to PC Perspective for more SFF PC coverage!

Club 3D launches Worlds First USB 3.0 to 4K Graphics Adapter

Subject: General Tech, Displays, Mobile | July 15, 2014 - 02:39 PM |
Tagged: displaylink, club 3d, 4k

Why would you want a USB 3.0 4K display adapter you might ask?  Perhaps you have an ultrabook with limited display outputs that do not output in 4K resolution but somehow you managed to get your hands on a 4K display for work or leisure and have a need for the full resolution.  Club 3D now has a family of USB adapters for you, the CSV-2302 USB 3.0 to DisplayPort 4K, CSV-2301 USB 3.0 to DisplayPort 1600p and the CSV-2300D USB 3.0 to DVI-I graphics adapters.  This is the first implementation of the DisplayLink DL-5500 chipset and it does indeed support 10bit colour if your display can handle it.

The MSRP for this device when it starts to ship in about 2 weeks will be ~$142.

CSV-2302.png

Club 3D officially launches the next generation of USB 3.0 Graphics adapters capable of outputting high resolutions to DVI-I (2048x 1152p), DisplayPort (2560x 1600p) and the world’s first USB 3.0 to DisplayPort Graphics (CSV-2302) adapter which supports 4K or Ultra High Definition resolution at 3840x 2160p.

The Universal Serial Bus (USB) Port of a desktop computer or notebook is multifunctional and can be used to connect a large variety of (storage) devices, keyboards, mice and and other peripherals like monitors. Back in 2011, Club 3D introduced its first SenseVision USB Graphics adapters. These small external graphics adapters can be used to connect a DVI or HDMI monitor to the USB 2.0 output of a Desktop Computer or Notebook and create a multi screen setup.

The SenseVision USB adapters proved to be very successful across the globe! Not only with travelers but also in (semi) professional environments where more monitors mean more productivity.

The new Club 3D USB 3.0 Graphics adapters are fully ‘Plug and Display’ certified and the USB 3.0 to 4K Graphics Adapter (CSV-2302) is the very first to use the brand new DisplayLink DL-5500 chipset enabling 4K Ultra High Definition output to DisplayPort enabled 4K monitors at 30Hz. The Club 3D USB 3.0 to 4K Graphics Adapter (CSV-2302) is the first device available worldwide with the revolutionary new DisplayLink SoC implemented.

This Graphics adapter uses little resources of your system so it won’t affect performance ensuring at the same time a great image quality. It’s the ideal solution for anyone wanting to expand desktop space in order to use multiple programs simultaneously.

White Quantum Dots are bright

Researchers may have found a less toxic alternative to using quantum dots in displays, the so called carbon dot which is a semiconductor that generate a rather cold light, in that they do not emit much yellow or red wavelengths.  Previously the CDs were used as the white light which shone through QDs but they contain cadmium or lead which tends to be strictly controlled when used in consumer goods.  Nanotechweb is reporting on the successful results of teams which are using cadmium free zinc copper indium sulphide core/shell QDs to produce displays with a significantly higher colour-rendering index than currently available LEDs are capable of, so we may still be on track for better displays in the next few years.

"By combining carbon dots that emit blue light and zinc copper indium sulphide quantum dots that emit in the green and red regions of the electromagnetic spectrum, researchers in China and the US have succeeded in making white light-emitting diodes with a high colour-rendering index of 93."

Tinkerers and developers received a nice gift today, an updated Raspberry Pi B+ which adds extra I/O to the existing platform which will allow you more functionality without needed to relearn how to program it.  The Broadcom BC2835 SoC is still present and still overclockable along with the 512MB of onboard RAM and most important the $35 price tag remains.  What has change is the number of USB ports which have double to four, a click in MicroSD port and an increase in the GPIO header to 40 pin, though it remains backwards compatible with 26 pin by plugging in on the left hand side which means you have not lost the work you put into the previous Pi.  Check out the introductory video at The Inquirer and feast your eyes on the new board layout below.

"Although it's not touted as Raspberry Pi Two, but rather "the final evolution of the original Raspberry Pi", the firm has tailored the Model B+ to include all of the additions that Raspberry Pi users have requested."

Raptr's Top Twenty Games of June 2014

There have been significant changes in the Top 20 list of most played PC games for June. Raptr, the service for PC gamers to update drivers, stream gameplay, and tune settings, records the number of hours played for each game, compiling it into a monthly list. While not sales figures, it does suggest how popular one game is compared to another -- at least if you want to factor in hours played, not just the number of players.

By far the most funny increase is Battlefield 3. This month, due to EA's Origin "On the House" program, the three-year-old shooter jumped thirty places, from 42nd to 12th. At the same time, Battlefield 4 dropped three places, from 7th to 10th, leaving it with just a 0.04% lead over its previous version. Jokes aside, this probably means that EA has a significant, untapped user base who would be interested in the Battlefield franchise.

Watch Dogs jumped eleven places, from 19th to 8th, which might sound surprising but was actually predicted by Raptr. The bigger surprise is how high it was in the last ranking, being that it launched on May 27th. That was a lot of usage for just a handful of days, almost as much as Team Fortress 2 had for the entire month.

Of course, League of Legends is still in first place, over doubling the game time of DOTA2.
