Will Intel Challenge nVidia In The GPU Space?

Intel has released details of its next -generation Xeon Phi processor and it is starting to look like Intel is gunning for a chunk of Nvidia’s GPU market.

According to a briefing from Avinash Sodani, Knights Landing Chief Architect at Intel, a product update by Hugo Saleh, Marketing Director of Intel’s Technical Computing Group, an interactive technical Q&A and a lab demo of a Knights Landing system running on an Intel reference-design system, Nvidia could be Intel’s target.

Knights Landing and prior Phi products are leagues apart and more flexible for a wider range of uses. Unlike more specialized processors, Intel describes Knights Landing as taking a “holistic approach” to new breakthrough applications.

The current generation Phi design, which operates as a coprocessor, Knights Landing incorporates x86 cores and can directly boot and run standard operating systems and application code without recompilation.

The test system had socketed CPU and memory modules was running a stock Linux distribution. A modified version of the Atom Silvermont x86 cores formed a Knights Landing ’tile’ which was the chip’s basic design unit consisting of dual x86 and vector execution units alongside cache memory and intra-tile mesh communication circuitry.

Each multi-chip package includes a processor with 30 or more tiles and eight high-speed memory chips.

Intel said the on-package memory, totaling 16GB, is made by Micron with custom I/O circuitry and might be a variant of Micron’s announced, but not yet shipping Hybrid Memory Cube.

The high-speed memory is similar to the DDR5 devices used on GPUs like Nvidia’s Tesla.

It looks like Intel saw that Nvidia was making great leaps into the high performance arena with its GPU and thought “I’ll be having some of that.”

The internals of a GPU and Xeon Phi are different, but share common ideas.

Nvidia has a big head start. It has already announced the price and availability of a Titan X development box designed for researchers exploring GPU applications to deep learning. Intel has not done that yet for Knights Landing systems.

But Phi is also a hybrid that includes dozens of full-fledged 64-bit x86 cores. This could make it better at some parallelizable application categories that use vector calculations.

AMD Goes Virtual With Liquid VR

AMD Liquid VR is not a retail product – it is an initiative to develop and deliver the best Virtual Reality (VR) experience in the industry.

AMD Liquid VR was announced at the Game Developers Conference in San Francisco, and the company describes it is a “set of innovative technologies focused on enabling exceptional VR content development” for hardware based on AMD silicon.

Developers will soon get access to the LiquidVR SDK, which will help them address numerous issues associated with VR development.

Platform and software rather than hardware

If you were expecting to see a sexy AMD VR headset with a killer spec, the announcement may be disappointing. However, if you are a “what’s under the bonnet” kind of geek, there are a few interesting highlights.

AMD has put a lot of effort into minimising motion-to-photon latency, which should not only help improve the experience, but also keep you from experiencing motion sickness, or hurling over that new carpet that really ties the room together.

Headline features of LiquidVR SDK 1.0 include:

Async Shaders for smooth head-tracking enabling Hardware-Accelerated Time Warp, a technology that uses updated information on a user’s head position after a frame has been rendered and then warps the image to reflect the new viewpoint just before sending it to a VR headset, effectively minimizing latency between when a user turns their head and what appears on screen.

Affinity Multi-GPU for scalable rendering, a technology that allows multiple GPUs to work together to improve frame rates in VR applications by allowing them to assign work to run on specific GPUs. Each GPU renders the viewpoint from one eye, and then composites the outputs into a single stereo 3D image. With this technology, multi-GPU configurations become ideal for high performance VR rendering, delivering high frame rates for a smoother experience.

Latest data latch for smooth head-tracking, a programming mechanism that helps get head tracking data from the head-mounted display to the GPU as quickly as possible by binding data as close to real-time as possible, practically eliminating any API overhead and removing latency.

Direct-to-display for intuitively attaching VR headsets, to deliver a seamless plug-and-play virtual reality experience from an AMD Radeon™ graphics card to a connected VR headset, while enabling features such as booting directly to the display or using extended display features within Windows.

What’s next for LiquidVR?

It all depends on what you were expecting, and what the rest of the industry does. AMD hopes LiquidVR will be compatible with a broad range of VR devices. LiquidVR will allow hardware makers to implement AMD technology in their products with relative ease, enabling 100Hz refresh rates, the use of individual GPUs per each eye and so on.

To a certain extent, you can think of LiquidVR as FreeSync for VR kit.

Oculus CEO Brendan Irbe said achieving presence in a virtual world is one of the most important elements needed to deliver a good user experience.

He explained where AMD comes in:

“We’re excited to have AMD working with us on their part of the latency equation, introducing support for new features like asynchronous timewarp and late latching, and compatibility improvements that ensure that Oculus’ users have a great experience on AMD hardware.”

Raja Koduri, corporate vice president, Visual Computing, AMD, said content, comfort and compatibility are the cornerstones of AMD’s focus on VR.

AMD’s resident graphics guru said:

“With LiquidVR we’re collaborating with the ecosystem to unlock solutions to some of the toughest challenges in VR and giving the keys to developers of VR content so that they can bring exceptional new experiences to life.”

A picture is worth a thousand words, so here’s 3300 frames of AMD’s virtual reality vision.

Can MediaTek Take On Qualcomm?

While Qualcomm’s 20nm Snapdragon 810 SoC might be the star of upcoming flagship smartphones, it appears that MediaTek has its own horse for the race, the octa-core MT6795.

Spotted by GforGames site, in a GeekBench test results and running inside an unknown smartphone, MediaTek’s MT6795 managed to score 886 points in the single-core test and 4536 points in the multi-core test. These results were enough to put it neck to neck with the mighty Qualcomm Snapdragon 810 SoC tested in the LG G Flex 2, which scored 1144 points in the single-core and 4345 in the multi-core test. While it did outrun the MT6795 in the single-core test, the multi-core test was clearly not kind on the Snapdragon 810.

The unknown device was running on Android Lollipop OS and packed 3GB of RAM, which might gave the MT6795 an edge over the LG G Flex 2.

MediaTek’s octa-core MT6795 was announced last year and while we are yet to see some of the first design wins, recent rumors suggested that it could be powering Meizu’s MX5, HTC’s Desire A55 and some other high-end smartphones. The MediaTek MT6795 is a 64-bit octa-core SoC clocked at up to 2.2GHz, with four Cortex-A57 cores and four Cortex-A53 cores. It packs PowerVR G6200 graphics, supports LPDDR3 memory and can handle 2K displays at up to 120Hz.

As we are just a few days from Mobile World Congress (MWC) 2015 which will kick off in Barcelona on March 2nd, we are quite sure that we will see more info as well as more benchmarks as a single benchmark running on an unknown smartphone might not be the best representation of performance, it does show that MediaTek certainly has a good chip and can compete with Qualcomm and Samsung.

AMD Headed To The Facial Recognition Space

AMD has developed facial recognition technology to enable users to organize and search video clips based on the people featured in them.

AMD executive Richard Gayle demonstrated to Tom’s Guide how AMD Content Manager, uses facial recognition to browse through a group of local videos to find specific faces.

There is an index that displays the people’s faces that have been detected throughout the video clips.

The user can edit the names of the people as well as add keyword tags to help improve future searches for specific people.

For instance, if you are searching for videos that feature one person, you can click on his or her respective face to pull up the corresponding videos.

Additionally, if you want to narrow a search to a specific person combined with a keyword tag, you can drag the face icon and click on the desired keyword.

Once you click on the video you wish to view, a player appears in the right windowpane, along with a timeline displayed at the bottom with a list of all the people who appear in the video.

The timeline is separated into various coloured boxes to mark the exact moment in the video when each person first appears on screen, so you do not have to watch the entire video to see the bit you want.

The application also has facial recognition capabilities that allow users to do some basic editing, such as compiling a single montage video of any individual or individuals.

While this is pretty good technology, it probably does not have any major use yet on its own.

Gayle said it is unlikely that AMD will release Content Manager in its current form but will license it to OEMs that are able to rebrand the application before offering it on their respective systems.

He claimed that only AMD processors have sufficient power to operate the application, because of the processor’s ability to have the CPU, GPU and memory controller work closely together.

AMD’s Fiji GPU Goes High Bandwidth

New evidence coming from two LinkedIn profiles of AMD employees suggest that AMD’s upcoming Radeon R9 380X graphics card which is expected to be based on the Fiji GPU will actually use High-Bandwidth Memory.

Spotted by a member of 3D Center forums, the two LinkedIn profiles mention both the R9 380X by name as well as describe it as the world’s firts 300W 2.5D discrete GPU SoC using stacked die High-Bandwidth Memory and silicon interposer. While the source of the leak is quite strange, these are more reliable than just rumors.

The first in line is the profile of Ilana Shternshain, an ASIC Physical Design Engineer, which has been behind the Playstation 4 SoC, Radeon R9 290X and R9 380X, which is described as the “largest in ‘King of the hill’ line of products.”

The second LinkedIn profile is the one from AMD’s System Architect Manager, Linglan Zhang, which was involved in developing “the world’s first 300W 2.5D discrete GPU SOC using stacked die High Bandwidth Memory and silicon interposer.”

Earlier rumors suggest that AMD might launch the new graphics cards early this year as the company is under heavy pressure from Nvidia’s recently released, as well as the upcoming, Maxwell-based graphics cards.

New Malware Targeting Apple Devices

Palo Alto Networks Inc  has uncovered a new group of malware that can infect Apple Inc’s  desktop and mobile operating systems, underscoring the increasing sophistication of attacks on iPhones and Mac computers.

The “WireLurker” malware can install third-party applications on regular, non-jailbroken iOS devices and hop from infected Macs onto iPhones through USB connector-cables, said Ryan Olson, intelligence director for the company’s Unit 42 division.

Palo Alto Networks said on Wednesday it had seen indications that the attackers were Chinese. The malware originated from a Chinese third-party apps store and appeared to have mostly affected users within the country.

The malware spread through infected apps uploaded to the apps store, that were in turn downloaded onto Mac computers. According to the company, more than 400 such infected apps had been downloaded over 350,000 times so far.

It’s unclear what the objective of the attacks was. There is no evidence that the attackers had made off with anything more sensitive than messaging IDs and contacts from users’ address books, Olson added.

But “they could just as easily take your Apple ID or do something else that’s bad news,” he said in an interview.

Apple, which Olson said was notified a couple weeks ago, did not respond to requests for comment.

Once WireLurker gets on an iPhone, it can go on to infect existing apps on the device, somewhat akin to how a traditional virus infects computer software programs. Olson said it was the first time he had seen it in action. “It’s the first time we’ve seen anyone doing it in the wild,” he added.

Amazon Tops Apple

A mere five months after Apple snatched J.D. Power’s tablet satisfaction award away from Samsung, it has lost it to up-and-coming Amazon.

Apple’s iPad finished in second place in the latest satisfaction survey conducted by J.D. Power and Associates, with a score of 824 out of a possible 1,000. For the first time, Amazon took first place, scoring 827.

Samsung came in at 821 for third, while Asus and Acer filled out the first five, but those stragglers’ scores were under the category average.

J.D. Power’s satisfaction score included five separate measurements for performance, ease of operation, features, styling and design, and cost, with each accounting for different percentages of the final number. Performance, for example, counted as 28% of the total; cost for 11%.

Apple received high scores in performance and styling and design, while Amazon performed best in ease of operation and cost, said Kirk Parsons, senior director of telecommunications services at J.D. Power.

“Within the tablet segment, there’s a balance of cost and value, and for this period, Amazon was at the equilibrium,” said Parsons. “For the money, [Amazon tablets] do what buyers need them to do. And the Mayday feature really helped them in ease of operation.”

Mayday is a feature on Amazon’s higher-end tablets that lets customers video chat with support representatives using the device.

Parsons called out Amazon’s Fire HDX, which launched in October 2013 in a 7-in. size and a month later in an 8.9-in. format, for driving the brand’s scores. Amazon now sells the 7-in. Fire HDX for $179; the 8.9-in. model starts at $379. “The new Fire HDX did really, really well” in the survey, Parsons noted.

J.D. Power polled nearly 2,700 U.S. tablet owners who had had their current devices for less than a year. The survey period ran from March to August.

The last time J.D. Power published tablet customer satisfaction scores, Amazon placed fourth. Its jump to first was a small surprise, said Parsons. “I figured [Amazon’s] scores would improve, but I didn’t think they’d take the top spot,” he admitted.

Price is increasingly important to satisfaction, said Parson, as costs fall and capabilities climb across the board, making it more difficult for premium-priced tablets like Apple’s iPad, to retain their polled positions. On average, tablet customers now spend $345 on their tablets, $48 less than in April 2013, a decline of 12%.

nVidia Finally Goes 20nm

For much of the year we were under the impression that the second generation Maxwell will end up as a 20nm chip.

First-generation Maxwell ended up being branded as Geforce GTX 750 and GTX 750 TI and the second generation Maxwell launched a few days ago as the GTX 980 and Geforce GTX 970, with both cards based on the 28nm GM204 GPU.

This is actually quite good news as it turns out that Nvidia managed to optimize power and performance of the chip and make it one of the most efficient chips manufactured in 28nm.

Nvidia 20nm chips coming in 2015

Still, people keep asking about the transition to 20nm and it turns out that the first 20nm chip from Nvidia in 20nm will be a mobile SoC.

The first Nvidia 20nm chip will be a mobile part, most likely Erista a successor of Parker (Tegra K1).

Our sources didn’t mention the exact codename, but it turns out that Nvidia wants to launch a mobile chip first and then it plans to expand into 20nm with graphics.

Unfortunately we don’t have any specifics to report.

AMD 20nm SoC in 2015

AMD is doing the same thing as its first 20nm chip, codenamed Nolan, is an entry level APU targeting tablet and detachable markets.

There is a strong possibility that Apple and Qualcomm simply bought a lot of 20nm capacity for their mobile modem chips and what was left was simply too expensive to make economic sense for big GPUs.
20nm will drive the voltage down while it will allow higher clocks, more transistors per square millimeter and it will overall enable better chips.

Just remember Nvidia world’s first quad-core Tegra 3 in 40nm was rather hot and making a quad core in 28nm enabled higher performance and significantly better battery life. The same was true of other mobile chips of the era.

We expect similar leap from going down to 20nm in 2015 and Erista might be the first chip to make it to 20nm. A Maxwell derived architecture 20nm will deliver even more efficiency. Needless to say AMD plans to launch 20nm GPUs next year as well.

It looks like Nvidia’s 16nm FinFET Parker processor, based on the Denver CPU architecture and Maxwell graphics won’t appear before 2016.

Can Lenovo Succeed With Tablets?

Lenovo on Friday said it would continue selling sub-10-in. Windows tablets in the U.S., backing away from statements it made the day before, when it said it was pulling the ThinkPad 8 from the North American market and had discontinued offering a model of the Miix 2.

“We will continue to bring new Windows devices to market across different screen sizes, including a new 8-inch tablet and 10-inch tablet coming this holiday,” Lenovo said in a press release published on its website Friday.

“Our model mix changes as per customer demand, and although we are no longer selling ThinkPad 8 in the U.S., and we have sold out of Miix 8-inch, we are not getting out of the small-screen Windows tablet business as was reported by the media (emphasis in original),” the statement continued.

On Thursday, the IDG News Service — like Computerworld, owned and operated by IDG – reported the withdrawal of the ThinkPad 8 and the 8-in. Miix from the U.S. market. The ThinkPad 8 had debuted in January at prices starting at $449, and the similarly-sized Miix had launched in October 2013.

Lenovo told IDG News that it was diverting remaining stocks of the ThinkPad 8 to other countries, including Brazil, China, and Japan, where demand was stronger for smaller Windows 8.1-powered tablets.

The China-based company, which has made impressive gains in the global market — it was the world’s largest personal computer seller during the second quarter, ahead of Hewlett-Packard and Dell, according to IDC — did not say exactly when it would return with an 8-in. device. If it begins selling the unnamed device in October, typical of OEMs that seed the channel then for the holiday sales season, it will have been absent from the market for two or more months.

ARM Launches Juno

ARM has announced two programs to assist Android’s ascent into the 64-bit architecture market.

The first of those is Linaro, a port of the Android Open Source Project to the 64-bit ARMv8-A architecture. ARM said the port was done on a development board codenamed “Juno”, which is the second initiative to help Android reach the 64-bit market.

The Juno hardware development platform includes a system on chip (SoC) powered by a quad-core ARM Cortex-A53 CPU and dual-core ARM Cortex-A57 CPU in an ARM big.little processing configuration.

Juno is said to be an “open, vendor neutral ARMv8 development platform” that will also feature an ARM Mali-T624 graphics processor.

Alongside the news of the 64-bit initiatives, ARM also announced that Actions Semiconductor of China signed a license agreement for the 64-bit ARM Cortex-A50 processor family.

“Actions provides SoC solutions for portable consumer electronics,” ARM said. “With this IP license, Actions will develop 64-bit SoC solutions targeting the tablet and over-the-counter (OTT) set top box markets.”

The announcements from ARM come at an appropriate time, as it was only last week that Google announced the latest version of its Android mobile operating system, Android L, which comes with support for 64-bit processors. ARM’s latest developments mean that Android developers are likely to take advantage of them in the push to take Android to the 64-bit market.

Despite speculation that it would launch as Android 5.0 Lollipop, Google outed its next software iteration on Wednesday last week as simply Android L, touting the oddly-named iteration as “the largest update to the operating system yet”.
