More Details Uncovered On AMD’s ZEN Cores
Comments Off on More Details Uncovered On AMD’s ZEN Cores
Our well informed industry sources have shared a few more details about the AMD’s 2016 Zen cores and now it appears that the architecture won’t use the shared FPU like Bulldozer.
The new Zen uses a SMT Hyperthreading just like Intel. They can process two threads at once with a Hyperthreaded core. AMD has told a special few that they are dropping the “core pair” approach that was a foundation of Bulldozer. This means that there will not be a shared FPU anymore.
Zen will use a scheduling model that is similar to Intel’s and it will use competitive hardware and simulation to define any needed scheduling or NUMA changes.
Two cores will still share the L3 cache but not the FPU. This because in 14nm there is enough space for the FPU inside of the Zen core and this approach might be faster.
We mentioned this in late April where we released a few details about the 16 core, 32 thread Zen based processor with Greenland based graphics stream processor.
Zen will apparently be ISA compatible with Haswell/Broadwell style of compute and the existing software will be compatible without requiring any programming changes.
Zen also focuses on a various compiler optimisation including GCC with target of SPECint v6 based score at common compiler settings and Microsoft Visual studio with target of parity of supported ISA features with Intel.
Benchmarking and performance compiler LLVM targets SPECint v6 rate score at performance compiler settings.
We cannot predict any instruction per clock (IPC improvement) over Intel Skylake, but it helps that Intel replaced Skylake with another 14nm processor in later part of 2016. If Zen makes to the market in 2016 AMD might have a fighting chance to narrow the performance gap between Intel greatest offerings.

AMD Coherent Data Reaches 100 GBs
After a lot of asking around, we can give you some actual numbers about the AMD’s coherent fabric.
The inter-connecting technology already sounded very promising, but now we have the actual number. The HSA, Heterogeneous System Architecture MCM (Multi Chip Module) that AMD is working on can give you almost seven times faster score than the traditional PCIe interface.
Our industry sources have confirmed that with 4 GMI (Global Memory Interconnect) links AMD’s CPU and GPU can talk at 100GB/s. the traditional PCIe 16X provides 15GB/s at about 500 ns latency. Data Fabric eliminates PCIe latency too.
AMD will be using this technology with the next gen Multi Chip module that packs a Zeppelin CPU (most likely packed with a bunch of ZEN cores) and a Greenland GPU that of course comes with super fast HBM (High Bandwidth Memory). The Greenland and HBM can communicate at 500 GB/s and can provide highest performance GPU with 4+ teraflops.
This new MCM package based chip will also talk with DDR4 3200 memory at 100GB/s speed making it quite attractive for the HSA computation oriented customers.
Did Microsoft Intentionally Delay The Surface Pro 4?
Comments Off on Did Microsoft Intentionally Delay The Surface Pro 4?
The latest rumors suggest that Microsoft was waiting to jack the latest Intel Skylake processor under its bonnet.
Redmond seemingly wants the new Surface Pro to be state of the art and be a tablet which is useful. Skylake will give it better battery life and performance with current industry standards like Bluetooth 4.1, Cat6 LTE, WiDi 6.0, and A4WP wireless charging weaved into it.
Intel will support the tablets through compatibility with 3D cameras and audio processing software plus better stylus interaction.
There is no sign of confirmation of the rumors. Microsoft has been quiet so far about the Surface Pro 4. We had been expecting it to highlight some of the better features of Windows 10.
However if the rumors are true it will be a hell of a lot better than the MacBook Air 2015 because it will feature innovation, rather than just being thin.
Latest news about its release date suggests a 2016 launch.
AMD Misses Again
Fabless chipmaker AMD has come up with a mixed set of results for the second quarter. The company managed to make as much cash as the cocaine nose jobs of Wall Street expected, but missed revenue expectations.
In fact its revenues were below the psychologically important billion figure at $942 million.
We knew it was going to be bad. Last week we were warned that the results would be flat. The actual figure was $942m, an 8.5 per cent sequential decline and a 34.6 per cent drop from the same period a year ago.
As you might expect, there are some measures of this not being AMD’s fault. The company is almost entirely dependent on PC sales. Not only have these fallen but don’t look like they are going to pick up for a while.
AMD’s Computing and Graphics division reported revenue of $379m, which was down 54.2 per cent, year-on-year. Its operating loss was $147m, compared to a $6m operating loss for last year’s quarter.
Lisa Su, AMD president and CEO, in a statement said that strong sequential revenue growth in AMD’s enterprise, embedded, and semi-custom segment and channel business was not enough to offset near-term problems in its PC processor business. This was due to lower than expected consumer demand that impacted sales to OEMs, she said.
“We continue to execute our long-term strategy while we navigate the current market environment. Our focus is on developing leadership computing and graphics products capable of driving profitable share growth across our target markets,” she added.
In the semi-custom segment, AMD makes chips for video game consoles such as the Nintendo Wii U, Microsoft Xbox One, and Sony PlayStation 4 consoles. That segment did reasonably well, up 13 percent from the previous quarter but down 8 percent from a year ago.
But AMD’s core business of processors and graphics chips fell 29 percent from the previous quarter and 54 percent from a year ago. AMD said it had decreased sales to manufacturers of laptop computers.
Figures like this strap a large target on AMD’s back with a sign saying “take me over” but AMD is not predicting total doom yet.
For the third quarter, AMD expects revenue to increase 6 percent, plus or minus 3 percent, sequentially, which is a fairly conservative outlook given the fact that Windows 10 is expected to push a few sales its way.
AMD supplies chips to the Nintendo Wii U, Microsoft Xbox One, and Sony PlayStation 4 consoles and these seem to be going rather well.
Sharp Pinning Hopes On In-car Displays

Comments Off on Sharp Pinning Hopes On In-car Displays
Struggling display manufacturer Sharp, reeling from cutthroat competition in mobile phones, will push car makers to incorporate vehicle dashboards that have gestural commands, thin bezels and other next-generation features.
It’s hoping cars will be controlled, in part, through high-resolution displays that can fit any two-dimensional surface area, such as dashboard panels with rounded contours.
The company has shown off the wavy screens for cars and consoles in recent months, and has tried to woo automakers to use them. Under the firm’s new medium-term strategy, the push has taken on greater urgency.
Thin-bezel dashboard LCDs, as well as screens that can provide multiple views to different passengers in a car depending on their perspective, could prove to be a lifeline for Sharp, which hasn’t been able to command a dominant market position despite cutting-edge technology.
Sharp is an Apple supplier and is said to be a maker of iPhone 6 screens, along with Japan Display, and LG Display of South Korea.
Apple sources some of its screens from Sharp’s Kameyama plants in central Japan, which produce the maker’s flagship IGZO (indium gallium zinc oxide) transparent crystalline semiconductor displays. IGZO displays, which Sharp began producing for smartphones in 2013, have smaller pixels than conventional LCD screens and feature low power consumption.
Last month, Sharp showed off a 5.5-inch display with 3860 x 2160 or 4K pixel resolution, which was part of a 12.5-inch IGZO panel. But there were no immediate plans for mass production.
Sharp’s ability to generate dazzling phone graphics hasn’t saved its bottom line. The firm announced a US$1.7 billion bailout from banks this week, its second lifeline in three years, and posted a dismal earnings performance for the year to March 31 with a net loss of ¥222.3 billion ($1.8 billion). It blamed declining prices in small and medium-sized LCDs.
In contrast, Sharp sees prices for automotive and industrial automation displays as more stable because the barriers to market entry are higher due to the technological know-how that’s required. Now it needs to play for time.
Did AMD Commit Fraud?
AMD must face claims that it committed securities fraud by hiding problems with the bungled 2011 launch of Llano that eventually led to a $100 million write-down, a US court has decided.
According to Techeye US District Judge Yvonne Gonzales Rogers said plaintiffs had a case that AMD officials misled them by stating in the spring of 2011 and will have to face a full trial.
The lawsuit was over the Llano chip, which AMD had claimed was “the most impressive processor in history.”
AMD originally said that the product launch would happen in the fourth quarter of 2010, sales of the Llano were delayed because of problems at the company’s chip manufacturing plant.
The then Chief Financial Officer Thomas Seifert told analysts on an April 2011 conference call that problems with chip production for the Llano were in the past, and that the company would have ample product for a launch in the second quarter.
Press officers for AMD continued to insist that there were no problems with supply, concealing the fact that it was only shipping Llanos to top-tier computer manufacturers because it did not have enough chips.
By the time AMD ramped up Llano shipments in late 2011, no one wanted them any more, leading to an inventory glut.
AMD disclosed in October 2012 that it was writing down $100 million of Llano inventory as not shiftable.
Shares fell nearly 74 percent from a peak of $8.35 in March 2012 to a low of $2.18 in October 2012 when the market learned the extent of the problems with the Llano launch.
Uber Suffers A Data Breach
The names and license plate numbers of about 50,000 Uber drivers were exposed in a security breach last year, the company revealed on Friday.
Uber found out about a possible breach of its systems in September, and a subsequent investigation revealed an unauthorized third party had accessed one of its databases four months earlier, the company said.
The files accessed held the names and license plate numbers of about 50,000 current and former drivers, which Uber described as a “small percentage” of the total. About 21,000 of the affected drivers are in California. The company has several hundred thousand drivers altogether.
It’s in the process of notifying the affected drivers and advised them to monitor their credit reports for fraudulent transactions and accounts. It said it hadn’t received any reports yet of actual misuse of the data.
Uber will provide a year of free identity protection service to the affected drivers, it said, which has become fairly standard for such breaches.
The company said it had filed a “John Doe” lawsuit Friday to help it confirm the identity of the party responsible for the breach.
Will Apple Go All-In On Car Batteries?

Comments Off on Will Apple Go All-In On Car Batteries?
A year and a half ago, Apple Inc applied for eight patents related to car batteries. Recently, it has added a slew of engineers, just one of whom had already filed for 17 in his former career, according to a Thomson Reuters.
The recent spate of hires and patent filings shows that Apple is fast building its industrial lithium-ion battery capabilities, adding to evidence the iPhone maker may be developing a car.
Quiet, clean electric cars are viewed in Silicon Valley and elsewhere as a promising technology for the future, but high costs and “range anxiety”, the concern that batteries will run out of power and cannot be recharged quickly, remain obstacles. Those challenges could also be seen as opportunities to find solutions to take the technology mainstream.
The number of auto-related patents filed by Apple, Google Inc, Korea’s Samsung, electric carmaker Tesla Motors Inc and ride-sharing startup Uber tripled from 2011 to 2014, according to an analysis by Thomson Reuters IP & Science of public patent filings.
Apple has filed far fewer of these patents than rivals, perhaps adding impetus to its recent hiring binge as it seeks to get up to speed in battery technologies and other car-building related expertise.
As of 18 months ago, Apple had filed for 290 such patents. By contrast, Samsung, which has been providing electric vehicle batteries for some years, had close to 900 filings involving auto battery technology alone.
The U.S. government makes patent applications public only after 18 months, so the figures do not reflect any patents filed in 2014.
Earlier this month, battery maker A123 Systems sued Apple for poaching five top engineers. A search of LinkedIn profiles indicates Apple has hired at least another seven A123 employees and at least 18 employees from Tesla since 2012.
The former A123 employees have expertise primarily in battery cell design, materials development and manufacturing engineering, according to the LinkedIn profiles and an analysis of patent applications.
A123, which filed for bankruptcy in 2012 but has since reorganized, supplied batteries for Fisker Automotive’s now-discontinued hybrid electric car.
“Looking at the people Apple is hiring from A123 and their backgrounds, it is hard not to assume they’re working on an electric car,” said Tom Gage, Chief Executive of EV Grid and a longtime expert in batteries and battery technology.
Apple is building its own battery division, according to the A123 lawsuit. Apple did not immediately respond to a request for comment.
Intel Gives Exascale A Boost
Intel’s exascale computing efforts have received a boost with the extension of the company’s research collaboration with the Barcelona Supercomputing Center.
Begun in 2011 and now extended to September 2017, the Intel-BSC work is currently looking at scalability issues with parallel applications.
Karl Solchenbach, Intel’s director, Innovation Pathfinding Architecture Group in Europe said it was important to improve scalability of threaded applications on many core nodes through the OmpSs programming model.
The collaboration has developed a methodology to measure these effects separately. “An automatic tool not only provides a detailed analysis of performance inhibitors, but also it allows a projection to a higher number of nodes,” says Solchenbach.
BSC has been making HPC tools and given Intel an instrumentation package (Extrae), a performance data browser (Paraver), and a simulator (Dimemas) to play with.
Charlie Wuischpard, VP & GM High Performance Computing at Intel said that the Barcelona work is pretty big scale for Chipzilla.
“A major part of what we’re proposing going forward is work on many core architecture. Our roadmap is to continue to add more and more cores all the time.”
“Our Knights Landing product that is coming out will have 60 or more cores running at a slightly slower clock speed but give you vastly better performance,” he said.
Nvidia Unveils New Tegra X1 Chip
Chipmaker Nvidia debuted a new processor aimed at powering high-end graphics on car dashboards as well as sophisticated auto-pilot systems.
At an event in Las Vegas ahead of the Consumer Electronics Show, Nvidia Chief Executive Jen-Hsun Huang said the Tegra X1 chip would provide enough computing horsepower for automobiles with displays built into mirrors, dashboard, navigation systems and passenger seating.
“The future car is going to have an enormous amount of computational ability,” Huang said. “We imagine the number of displays in your car will grow very rapidly.”
The Tegra X1 has twice the performance of its predecessor, the Tegra K1, and will come out in early 2015, Nvidia said.
An upcoming platform combining two of the X1 chips can process data collected from up to 12 high-definition cameras monitoring traffic, blind spots and other safety conditions in driver assistance systems, Huang said.
Combined with next-generation software, the chips can help detect and read road signs, recognize pedestrians and detect braking vehicles, he said.
Santa Clara, California-based Nvidia in recent years has been expanding beyond its core business of designing high-end graphics chips for personal computers.
After struggling to compete against larger chipmakers like Qualcomm in smartphones and tablets, Nvidia is now increasing its focus on using its Tegra mobile chips in cars and is already supplying companies including Audi, BMW and Tesla.
