Graphene May Give Processors A Boost
Researchers at MIT have figured out that graphene, sheets of atom-thick carbon, could be used to make chips a million times faster.
The researchers have worked out that slowing the speed of light to the extent that it moves slower than flowing electrons can create an “optical boom”, the optical equivalent of a sonic boom.
Slowing the speed of light is no mean feat, but the clever folks at MIT managed it by using the honeycomb shape of carbon to slow photons to slow photons to several hundredths of their normal speed in a free space, explained researcher Ido Kaminer.
Meanwhile, the characteristics of graphene speed up electrons to a million metres a second, or around 1/300 of the speed of light in a vacuum.
The optical boom is caused when the electrons passing though the graphene reach the speed of light, effectively breaking its barrier in the carbon honeycomb and causing a shockwave of light.
As electrons move faster than the trapped light, they bleed plasmons, a form of virtual particle that represents the oscillation of electrons on the graphene’s surface.
Effectively, it is the equivalent of turning electricity into light. This is nothing new – Thomas Edison did it a century ago with fluorescent tubes – but it can efficiently and controllably generate plasmons at a scale that works with microchip technology.
The discovery could allow chip components to be made from graphene to enable the creation of light-based circuits. These circuits could be the next step in the evolution of chip and computing technology, as the transfer of data through light is far faster than using electrons in today’s chips, even the fast pixel-pushing ones.
So much faster that it’s “six orders of magnitude higher than what is used in electronics”, according to Kaminer. That’s up to a million times faster in plain English.
“There’s a lot of excitement about graphene because it could be easily integrated with other electronics,” said physics professor Marin Soljačić, a researcher on the project, who is confident that MIT can turn this theoretical experiment into a working system. “I have confidence that it should be doable within one to two years.”
This is a pretty big concept and almost sci-fi stuff, but we’re always keen to see smaller and faster chips. It also shows that the future tech envisioned by the world of sci-fi may not be that far away.

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.
Google Goes Quantum
When is a blink not a natural blink? For Google the question has such ramifications that it has devoted a supercomputer to solving the puzzle.
Slashgear reports that the internet giant is using its $10 million quantum computer to find out how products like Google Glass can differentiate between a natural blink and a deliberate blink used to trigger functionality.
The supercomputer based at Google’s Quantum Artificial Intelligence Lab is a joint venture with NASA and is being used to refine the algorithms used for new forms of control such as blinking. The supercomputer uses D-Wave chips kept at as near to absolute zero as possible, which makes it somewhat impractical for everyday wear but amazingly fast at solving brainteasers.
A Redditor reported earlier this year that Google Glass is capable of taking pictures by responding to blinking, however the feature is disabled in the software code as the technology had not advanced enough to differentiate between natural impulse and intentional request.
It is easy to see the potential of blink control. Imagine being able to capture your life as you live it, exactly the way you see it, without anyone ever having to stop and ask people to say “cheese”.
Google Glass is due for commercial release next year but for the many beta testers and developers who already have one this research could lead to an even richer seam of touchless functionality.
If nothing else you can almost guarantee that Q will have one ready for Daniel Craig’s next James Bond outing.
Intel Releases 16GB Xeon Phi
Intel has announced five Xeon Phi accelerators including a high density add-in card while upping memory capacity to 16GB.
Intel has managed to get its Xeon Phi accelerator cards to power the Tianhe-2 cluster to the summit of the Top 500 list, however the firm isn’t waiting around to bring out new products. At the International Supercomputing show, Intel extended its Xeon Phi range with five new products, all of which have more than one TFLOPS double precision floating point performance, and the Xeon Phi 7120P and 7120X cards, which have 16GB of GDDR5 memory.
Intel’s Xeon Phi 7120P and 7120X cards have peak double precision floating point performance of over 1.2 TFLOPS, with 352GB/s bandwidth to the 16GB of GDDR5 memory. The firm also updated its more modest Xeon Phi 3100 series with the 3120P and 3120A cards, both with more than one TFLOPS of double precision floating point performance and 6GB of GDDR5 memory with bandwidth of 240GB/s.
Intel has also brought out the Xeon Phi 5120D, a high density card that uses mini PCI-Express slots. The firm said that the Xeon Phi 5120D card offers double precision floating point performance of more than one TFLOPS and 8GB of GDDR5 memory with bandwidth greater than 300GB/s.
That Intel is concentrating on double precision floating point performance with its Xeon Phi accelerators highlights the firm’s focus on research rather than graphics rendering or workstation tasks. However the firm’s ability to pack 16GB into its Xeon Phi 7100 series cards is arguably the most important development, as larger locally addressable memory means higher resolution simulations.
Intel clearly seems to believe that there is significant money to be made in the high performance PC market, and despite early reservations from industry observers the firm seems to be ramping up its Xeon Phi range at a rate that will start to give rival GPGPU accelerator designer Nvidia cause for concern.

Comments Off on Intel Shows More Ivy Bridge
Last week Intel officially released Haswell, but there’s still life in good old Ivy Bridge. The chipmaker has announced a range of low-end Ivy parts and even a Sandy Bridge based Celeron.
The Celeron G470 is possibly the last consumer Sandy Bridge we will ever see. It is a single-core 35W part clocked at 2GHz and it’s priced at just $37.
However, Ivy Bridge parts are a bit more interesting. They include the Celeron 1017, a dual-core, dua-thread chip clocked at 1.6GHz, with a TDP of just 17W. It costs $86 and should be a nice part for low-end laptops and nettops. The Celeron 1005M also costs $86, but it has a 35W TDP and a 1.9GHz clock.
There are four new G2000 Pentiums as well. The G2140 and G2030 are 55W parts, clocked at 3GHz and 3.3GHz respectively. The G2120T and G2030T are 35W chips, clocked at 2.6GHz and 2.7GHz. They cost $64 and $75 respectively. Of course, Pentiums don’t feature Hyperthreading and all four of them are dual-core parts.
The Core i3 line-up also got some speed bumps. The Core i3-3245 and 3250 are clocked at 3.4 and 3.5GHz and both have a TDP of 55W. The 3245 features HD 4000 graphics and costs $134, while the 3250 ends up with HD 2500 graphics and a price tag of $138. Lastly, the Core i3-3250T is a 3GHz part with a 35W TDP, it costs $138, just like its 55W sibling.
Intel’s Pentium Getting Updated
Intel is going to update its desktop Pentium family with several slightly faster Ivy Bridge-based processors.
According to CPU World the chips should hit the shops in the second quarter of 2013 which is a quarter after January’s refresh of budget desktop families, and one quarter before the launch of Haswell. The new chips have the original titles of Pentium G2030, G2030T, G2120T and G2140. They will have two cores, but lack Hyper-Threading technology, and can run two threads before getting all confused.
Both the G2000 and G2100 series CPUs support only basic features, like Intel 64 and Virtualization. They do integrate HD graphics which are clocked at 650 MHz and dual-channel memory controller, that supports DDR3-1333 on the G2030 and the G2030T, and up to DDR3-1600 on the G2120T and the G2140.
Pentium G2030T and G2120T are low-power models, replacing G2020T and G2100T but are clocked 100 MHz higher, that is at 2.6GHz and 2.7GHz respectively. However they still fit into 35 Watt thermal envelope. Pentium G2030 and G2140 mainstream microprocessors will be faster than “T” SKUs, and they will have 57 per cent higher TDP. Intel expects these to replace the G2020 and G2130 SKUs. The G2030 will run at 3 GHz. The G2140 will operate at 3.3 GHz. No word on prices yet.
Ivy Bridge E Delayed Until Fall
y Bridge E, Intel’s ultra-high end chip that is set to replace the Core i7 3970X, has been delayed. It doesn’t look like it was anything major. Our sources tell us that the decision was made by Intel server guys who did not want to launch this chip in Q3 as originally indented.
Since Q3 starts in July, a relatively slow month for IT, the normal time to launch products is late August or September, but at this time there is no confirmation that this will happen at this time.
Sandy Bridge E, or Core i7 3960X, was launched in Q4 2011, November 14th to be precise. This can give you a clue on when to expect the successor.
Originally Ivy Bridge E was supposed to launch in Q3, one quarter after the launch of quad-core Desktop Haswell processors. Ivy Bridge E works in X79 motherboards but we do expect that a few key motherboard vendors will have their newer versions ready for the launch of the new $999 flagship processor.
If Intel continues at this pace, it will take quite a while before we see Haswell E in action.
Quantum Computing Making Strides
Researchers at the University of Innsbruck in Austria have managed to transfer quantum information from an atom to a photon, which is being seen as a breakthrough in the making of quantum computers.
According to Humans Invent the breakthrough allows quantum computers to exchange data at the speed of light along optical fibres. Lead researcher on the project Tracy Northup said that the method allows the mapping of quantum information faithfully from an ion onto a photon.
Northup’s team used an “ion trap” to produce a single photon from a trapped calcium ion with its quantum state intact using mirrors and lasers. No potential cats were injured in the experiment. The move enables boffins to start to play with thousands of quantum bits rather than just a dozen or so. This means that they can get a computer to do specific tasks like factoring large numbers or a database search, faster.
Intel Makes Changes To Haswell
Intel has started dividing its mobile market segments into processors lines, where the Y processor line goes up to 11.5W TDP, U line covers chips in the 15W to 25W range, while the M line covers 37W, 47W as well as 57W TDP space, with two to four cores and graphics up to GT2.
The high performance H processor line is yet another BGA package processor line that also aims for 37W, 47W and 57W TDPs, with quad-core processors and up to GT3 graphics with on-package cache memory.
Intel expects that high performing gaming and workstation PCs will go use these processors and they fit some thick clamshell designs, no Ultrabooks with 57W unless you would want to use one for welding.
Intel currently doesn’t detail the processor number and the number of SKUs but it is obvious that they will end up with quad-core Core i7 branding for QC1+ and QC2+ market segments.
Intel’s Haswell Goes 13W
Intel’s Haswell Y-series processors as we said a few weeks ago have yet launch. The current plan is to launch two Ivy SKUs in Q1 2013, both dual-cores, and later in 2013 Intel plans to replace them with Haswell Y series parts, with even lower TDP.
The faster one is called Core i7 3689Y and has two cores and two threads, as well as a base clock of 1.5GHz. With the help of Intel Turbo Boost 2.0, the top single-core turbo clock is an impressive 2.6GHz, while the maximum dual-core turbo clock stops at 2.4GHz, which is still impressive. This core comes with Intel HD graphics 4000 clocked between 350MHz and 860MHz with turbo.
This new core supports both DDR3 and DDR3L at 1600MHz, has 4MB of cache and impressively low 13W TDP. We have explained that SDP stands for Standard Dissipation Power and Intel expect it to be at 7W for this part.
The runner up is called Core i5 3439Y and has the same two cores and two threads with 1.5GHz base clock, but the single core turbo clock stops at 2.3GHz, while the dual-core top clock is 2.10GHz. The graphics speed, TDP and memory support remain the same, but there is a difference in cache size. Core i5 3439Y comes with 3MB instead of 4MB for Core i7 Y series 3689Y part.
