Unless you opt for one of the very low-power CPUs on the market today, chances are the processor inside your desktop PC has a fan attached to keep it cool. The higher performance the chip and the more you overclock, the more cooling required. And more cooling inevitably means more noise unless you go with a water cooling solution.

Specialist cooling company Noctua has teamed up with RotoSub to come up with a low noise solution that allows you to stick with air cooling, but removes the noise. They’ve done this by adding active noise cancellation to one of their CPU coolers for the very first time. A project that’s been ongoing for over a year.

The cooler is still in prototype form, but was on display at Computex 2013. It could actually be referred to as a cooling cube looking at the design, but is based on Noctua’s NH-D14 cooler using a twin-tower heatsink, which consists of two heatsink blocks and a fan mounted between them.

The noise cancellation is achieved through a combination of mic and speakers. The mic listens to the sound created by the cooler, then the speakers output the same sound with a phase difference. In so doing, destructive interference is created and the level of noise is cut significantly.

According to those able to listen to the prototype CPU cooler, there was actually no noise heard when the system was active. If you watch the demonstration video above you can clearly hear the difference the noise cancellation makes.

Such a system is sure to be popular and no doubt expensive. Based on the design, it should be possible to develop versions that work with all motherboards and CPUs, meaning Noctua could certainly have a hit on its hands here.

DailyTech – Intel Shows 22nm 50-Core “Knights Corner” CPU

Over 1 TeraFLOPS on a single chip

22517_large_22513_large_KnightsCorner
GPGPU and cloud computing have been hot topics for the last several years. Intel has shown off several designs like Larrabee and the Single-chip Cloud Computer in the past. However, it is Knights Corner that will be the firm’s first commercial product to use the Many Integrated Core (MIC) architecture. The co-processor will be offered as a PCIe add-in board.

The MIC concept is simple: Use architecture specifically designed to process highly parallel workloads, but ensure compatibility with existing x86 programming models and tools.

This would give MIC co-processors the ability to run existing applications without the need to port the code to a new programming environment, theoretically allowing maximum CPU and co-processor performance simultaneously with existing x86 based applications. This would dramatically save time, cost and resources that would otherwise be needed to rewrite them to alternative proprietary languages.

AMD and NVIDIA have been trying to do with their latest architectures by enabling support for languages like C++, but Intel wants to challenge them in this potentially lucrative market.

Knights Corner will be manufactured using Intel’s latest 3-D Tri-Gate P1270 22nm transistor process and will feature more than 50 cores. Intel demonstrated first silicon of Knights Corner at the SC11 conference yesterday. The co-processor wowed the crowd by delivering more than 1 TeraFLOPS of double precision floating point performance.

The firm also touted its “commitment to delivering the most efficient and programming-friendly platform for highly parallel applications”, and showed off the benefits of the MIC architecture in weather modeling, tomography, protein folding, and advanced materials simulation at its booth.

There is no timeframe on when Knights Corner will enter production or be available to customers.

    Multi-Core Goes Mainstream, Computing Pushed to Extremes

    NEWS HIGHLIGHTS

    • New “Near Threshold Voltage Processor” from Intel Labs challenges the computing system status quo with an experimental Pentium®-class Intel® architecture CPU delivering five times the energy efficiency and the ability to run off a solar cell the size of a postage stamp.
    • Intel Labs released a “Parallel JS” engine to the open source community, adding data-parallel capabilities to JavaScript™ to speed up browser-based services such as computer vision, cryptography, and 3-D games by up to 8-fold.
    • Intel Labs unveiled the Hybrid Memory Cube with 7-times better energy efficiency than today’s DDR3 memory along with the highest data rates ever seen in a single DRAM device.
    • Intel CTO Justin Rattner highlighted the accelerating impact of multi- and many-core computing, expanding beyond HPC with developers solving a wide range of everyday computing problems on both clients and servers.

    INTEL DEVELOPER FORUM, San Francisco, Sept. 15, 2011 – Citing the impact of multi- and many-core computing hitting the mainstream and new developments in extreme scale computing as examples, Justin Rattner, Intel’s chief technology officer, told an Intel Developer Forum audience that the future of computing is being accelerated.

    “Since 2006 Intel and the IA developer community have worked in partnership to realize the potential of multi- and many-core computing, with accelerating impact beyond high-performance computing to solving a wide range of real-world computing problems on clients and servers,” Rattner said during his Day 3 keynote in San Francisco. “What we have demonstrated today only scratches the surface of what will be possible with many-core and extreme scale computing systems in the future.”

    Computing to the Extreme

    Intel continues to push tech beyond today’s limits, looking for the next big leaps that take computing to the next levels of performance with much less power consumption than is possible today. As an example, Rattner demonstrated a Near-Threshold Voltage Processorusing novel, ultra-low voltage circuits that dramatically reduce energy consumption by operating close to threshold, or turn-on voltage, of the transistors. This concept CPU runs fast when needed but drops power to below 10 milliwatts when its workload is light – low enough to keep running while powered only by a solar cell the size of a postage stamp. While the research chip will not become a product itself, the results of this research could lead to the integration of scalable near-threshold voltage circuits across a wide range of future products, reducing power consumption by 5-fold or more and extending always-on capability to a wider range of computing devices. Technologies such as this will further Intel Labs’ goal to reduce energy consumption per computation by 100- to1000-fold for applications ranging from massive data processing at one end of the spectrum to terascale-in-a-pocket at the other.

    The Hybrid Memory Cube, a concept DRAM developed by Micron* in collaboration with Intel, demonstrates a new approach to memory design delivering a 7-fold improvement in energy-efficiency over today’s DDR3. Hybrid Memory Cube uses a stacked memory chip configuration, forming a compact “cube,” and uses a new, highly efficient memory interface which sets the bar for energy consumed per bit transferred while supporting data rates of one trillion bits per second. This research could lead to dramatic improvements in servers optimized for cloud computing as well as ultrabooks, televisions, tablets and smartphones

    Multicore’s Many Uses

    Multi-core, the practice of building more than one processing engine into a single chip, has become the accepted method to increase performance while keeping power consumption low. While many-core is more of a design perspective, rather than incrementally adding cores in a traditional approach, it’s reinventing chip design based on the assumption that high core counts is the new norm.

    Rattner highlighted the progress multi-core computing has seen since he introduced Intel’s first dual-core processor at IDF 5 years ago. Today Intel’s multi- and many-core processors are hosting a myriad of important applications across a wide range of industry sectors, including some surprising new uses in the rapidly advancing world of high-core-count computing.

    Rattner described some of the latest applications of this technology along with the software tools and programming techniques that are enabling developers to harness the power of multi- and many-core computing in several key areas, including:

    • Faster Web Apps: Extending JavaScript™ with data-parallel programming features, using a just-released experimentalParallel JS open-source engine from Intel Labs, to enable a new class of browser-based apps in domains such as photo and video editing, physics simulation, and 3-D gaming for desktop and mobile personal computers, including Ultrabooks™.
    • More Responsive Cloud Services: Best-in-class increases in queries per second for Memcached applications using the multi-core capabilities of Intel’s 2nd Generation Intel® Core™ microprocessor to enable the world’s largest Internet sites to improve their Web app responsiveness and minimize user wait times for critical data.
    • Improved PC Client Security: Parallel cryptographic and facial recognition services to improve security on Ultrabooks and traditional notebook and desktop personal computers by utilizing all of the IA and graphics cores on 2nd Generation Intel Core microprocessors in a heterogeneous fashion.
    • Lower Cost Wireless Infrastructure: Collaborative research with China Mobile to replace the custom and costly base-station hardware used on cell towers today with a fully programmable and far more cost-effective, software-based PC alternative.
    • Really Big Science: Unlocking the mysteries of the universe by utilizing clusters of Intel multi-core processors at CERN* to greatly improve their high-energy physics app performance and to quickly port their code to Intel’s upcoming Many Integrated Core (MIC) architecture product family.

    DailyTech – Windows 8 Appears to be Running Happily on ARM CPUs

    Watch out Intel and AMD, power efficient ARM processors will soon be able to run Windows

    19469_IE10_Runs_on_ARMAt CES 2011, Microsoft Corp. (MSFT) CEO Steve Ballmer showed off an early build of a next generation Windows operating systemrunning on an ARM architecture CPU.  This week at Microsoft’s MIX Developer Conference in Las Vegas, the company gave developers a surprise Easter egg — apreview build of Internet Explorer 10 and its underlying version of Windows were running on a 1 GHz ARM processor.

    Samsung Electronics (005930), Texas Instruments Inc. (TXN), Qualcomm Inc. (QCOM), NVIDIA Corp. (NVDA), and other ARM chipmakers have all been hard at work cooking up power savvy multicore offerings, which would be perfect for a netbook or notebook.

    Versus similarly clocked x86 processors from Intel or AMD, ARM processors would likely squeeze out an hour or two of extra battery life.  While die shrinks and the ever-rising leakage current may eventually largely negate this advantage, in the short term ARM presents the first compelling consumer alternative to x86 in decades.

    Windows 8 is expected to insert Microsoft’s Ribbon UI element into more locations, including Windows Explorer.  It is also expected to have deeper touch integration and tie together the PC version of Windows with the Metro UI that Microsoft developed for the defunct Zune and Windows Phone 7.

    But the addition of ARM support is perhaps the most anticipated feature.

    While ARM currently offers power advantages, how compelling a buy Windows ARM portables will be still remains to be seen.  By offering base Windows support, including access to its Office suite and other enterprise tools, Microsoft makes ARM accessible to the everyday consumer.

    But exactly how far Microsoft is able to go with its compatibility efforts remains to be seen.  If Microsoft can add ARM support for the Direct X and sound libraries, for example, it would be a relatively trivial exercise for developers to recompile their executables for ARM-architecture Windows 8 computers.

    Microsoft makes the world’s most used development environment, Microsoft Visual Studio.  By adding tools to make it quick and easy to switch from x86 to ARM builds, Microsoft could make applications compatibility complaints largely a moot point.

    Likewise, if Microsoft can embed an ARM-specific virtual machine in the OS with an x86 emulation layer, it might be possible to run native x86 apps, as is, without recompilation.  This would be helpful in cases where a company didn’t have the source and the application developer was unresponsive or unwilling to make the change.  Implementing the same sort of system to provide ARM emulation in x86 Windows would be even more helpful to ARM, because it would allow developers to effectively target the more efficient ARM architecture, while ignoring x86.

    Ultimately the question also still remains how low Intel can price its options and how big the true gap in power efficiency will be.  Unlike in the past, Intel may now find its pricing ability hindered by new international scrutiny that prevents it from resorting to anti-competitive arrangements to try to stomp out pesky rivals like ARM. But the exact picture is unclear.

    Even more unclear is the fate of Microsoft tablets.  Even if ARM takes off in the notebook space, it may do little to help Microsoft sell Windows tablets, with Apple and Android so deeply entrenched.  In that regard, Microsoft may find that it’s just given ARM a free ride to major expansion.  If that’s the case Microsoft’s customers should still reap minor gains — a positive for the company — but Microsoft itself may not make significant in-roads in its market expansion hopes.
