If you've been following the tech or security news for the past few days, then you no doubt know of a security vulnerability that reportedly affects all Intel processors. OS vendors have been working to mitigate the issue with kernel patches, but those software Band-Aids can come with some performance handicaps as a side effect. Today, we're learning more about what exactly is going on, and that there are not one, but actually two vulnerabilities that have been disclosed. It's bad enough that one of them targets Intel processors, but the second affects ALL modern processors as well -- including those based on architectures from Intel, AMD and ARM. So, we present to you Meltdown and Spectre.... Read more...
Yesterday, Qualcomm announced that its Centriq 2400 Series processors are now shipping to its customers, nearly a year after it began sampling the chips. Available in 40-, 46- and 48-core versions, the Qualcomm is positioning Centriq 2400 as a worthy competitor to Intel's Xeon processors in the data center server market. Up until this point, Qualcomm has contended that the 48-core Centriq 2460 offers a 4x improvement in performance-per-dollars versus the Intel Xeon Platinum 8180. While those figures are much appreciated, we wanted to see some real world benchmark data so that we can make our own conclusions. Thankfully, the folks at Cloudflare were able to put a 46-core Centriq 2452 up against... Read more...
Today, Qualcomm officially announced that it has begun shipping its Centriq 2400 server processors to its OEM partners. This marks a big step for Qualcomm, which is no stranger to the mobile market with its Snapdragon processors, but is a lesser known quantity in the server market. Intel's Xeon processors have already seen a credible challenge in the form of AMD's Zen-based EPYC family, and Centriq promises to be a low-power, high-density alternative that can run with the big dogs in the cloud infrastructure market. Qualcomm first began talking up its Centriq family around this time last year. At the time, the company was sampling the processors, which are built on a Samsung 10-nanometer manufacturing...

There is a ton of attention being paid to artificial intelligence and machine learning in the tech industry at the moment, encompassing a variety of fields, everything from digital assistants in smartphones and other gadgets, to self-driving vehicles, and more. It is no surprise, then, that chipmaker ARM has gone and created a new machine learning group to accelerate its efforts in AI as it continues to develop increasingly sophisticated processors.ARM confirmed the new division to EE Times, though it appears a bit gun shy to get into specifics, such as how many people will comprise the dedicated AI group or how much the company is investing into it. Speaking vaguely, Rene Haas, president of... Read more...
A myriad of devices are powered by processors or SoCs featuring ARM technology. From your smartphone or smartwatch, to your router or media streamer -- and a multitude of devices in between -- odds are that an ARM-based processor has some sort of impact on your daily life. While out covering ARM TechCon, which is currently underway in Santa Clara, we got a glimpse of a device being built by Heartfelt Technologies leveraging ARM processors by way of the popular Raspberry Pi, that could actually end up saving your life.The device is wall-mounted camera system for in-home patient monitoring, which captures cardiovascular information whenever a patient walks past. The camera system specifically looks... Read more...
There's no question that our connected devices are increasingly coming under attack, as we witnessed with the Mirai botnet that made the rounds late last year. In an effort to shore up the defenses of these IoT devices, ARM is pushing forwards with what it calls its Platform Security Architecture (PSA). With PSA, ARM is providing what it calls the first common framework for building connected devices that are more secure. ARM views PSA as "a fundamental shift in the economics of IoT security" by providing clear guidelines to help make securing our devices more efficient and cost effective from a developer’s perspective. To help energize these efforts, ARM will introduce an open source reference... Read more...
Well, this is not good. Chunks of source code related to internal Windows builds that have not yet been released to the general public were leaked online. According to The Register, a "massive treasure trove" totaling 32TB of official and non-public installation images and software blueprints was compressed down to 8TB and uploaded to BetaArchive.com, an online repository for beta software and what is known as abandonware.Image Source: Flickr (Julien GONG Min) Why this is potentially a big deal is because having access to source code—in this case, code that is normally closely guarded—allows hackers to look for vulnerabilities and then write exploits for them. According to the initial report,... Read more...
ARM has developed a new generation of mobile chips that will empower smartphones and tablets of tomorrow with machine learning and artificial intelligence capabilities, along with claimed significant increases in power efficiency and performance. The company's new Cortex-A75 CPU core for premium, high performance device requirements and Cortex-A55 processors for mobile power-efficient workload processing will also both be the first to feature ARM's DynamIQ technology, which gives design partners like Qualcomm more flexibility in how they pair CPU clusters. Prior to ARM's DynamIQ design, Qualcomm and others could employ big.LITTLE designs that paired a cluster of high-performing CPUs with the... Read more...
With all the attention surrounding Windows 10 S right now, it’s easy to forget that Microsoft has another variant of Windows 10 arriving later this year. In late 2016, Microsoft announced that it is working on a Windows 10 SKU that will run natively on Qualcomm’s Snapdragon processors. In a move that makes Windows 10 on ARM more capable than Windows 10 S, Microsoft announced this week at Build 2017 that the former will support all of your legacy Win32 apps. “You also have all of the apps that you’re used to,” said Microsoft Group Product Manager Hari Pulapaka during the Windows 10 on ARM Build 2017 session. Windows 10 on ARM running on a Snapdragon 835 (all 8 cores functional) “For example, all... Read more...
ARM has become a name that is synonymous with highly efficient (and powerful) chip designs; designs that power a wide variety of devices that we come in contact with on a daily basis. Chances are that there is an ARM chip in your smartphone, tablet, wireless router, media streamer, or even in your state-of-the art “connected” car. But as we enter into an age where artificial intelligence (AI) is becoming a bigger part of our lives, we need even more powerful processors to leverage these capabilities. As a result, ARM is looking to advance its big.LITTLE architecture with a forward-looking design that will stretch into the next decade. With that in mind, ARM is announcing its DynamIQ architecture,... Read more...
Last week, Microsoft made a surprise mention that it had been working with Qualcomm to bring Windows Server to ARM, a tidbit that no doubt sent many into a frenzy. At Intel, we wouldn't be surprised if a little bit of anxiety was felt.  From a consumer or enterprise standpoint, Windows Server on ARM could sound like an interesting route to take. Well, as it happens, Microsoft didn't announce that Windows Server was going to become available for ARM. Instead, the company has been using WS on ARM internally, and as for now, that's not going to be changing. ZDNet's Mary Jo Foley verified this through a bit of prodding, with Microsoft explicitly stating that this interesting OS release is for... Read more...
Qualcomm isn’t the only manufacturer looking to cut into Intel’s seemingly insurmountable lead in the server chip market. We’re also seeing a challenge from lesser known MACOM, which is employing an ARM chip design that promises high performance (particularly in regards to memory bandwidth) with incredible efficiency. MACOM’s X-Gene 3 is built using a 16nm FinFET manufacturing process, features 32 64-bit ARMv8-A cores running at 3GHz, supports 16 DIMMs via eight DDR4-2667 memory channels (up to 1TB of memory is supported) and 42 PCIE Gen 3 lanes. MACOM claims that the X-Gene 3, which is now shipping to select customers, is "the most powerful ARM CPU available today". One curious bit of wording... Read more...
As if AMD’s new Ryzen processors weren’t enough to make Intel grab for a bottle of antacids, it looks as though Microsoft’s latest partnership could challenge the world’s dominant processor manufacturer in the lucrative server market (Intel commands well in excess of 90 percent of the server chip market according to IDC). No, we’re not talking about AMD’s Naples server chips, which also should give Intel pause, but Microsoft's efforts to ensure that Qualcomm ARM processors can run its Windows Server operating system. Microsoft says that it has already built a version of Windows Server that offers native support for ARM chips, and it is using this branch of the operating system for its own internal... Read more...
Apple’s notebook computers aren’t exactly known as energy hogs — well, if we toss aside the Consumer Reports battery fiasco that was attributed to a Safari bug — but it’s always appreciated to eek as much battery life as possible out of a machine. Given that Apple has full control over the hardware and software stack of its products, it has always had an advantage when it comes to optimizing for power efficiency. A new report indicates that Apple is taking an additional step in its efforts to increase Mac battery life by developing a custom ARM chip that will handle low-power tasks, easing the burden of the primary Intel processor. According to well-connected Apple insider Mark Gurman, the chip... Read more...
ARM and TSMC have become quite the duo over the years, combining the latter's cutting-edge process technologies with the former's processor IP. It is a partnership that has been working, hence why the two committed earlier this year to collaborating on a marketable 7nm FinFET chip. The fruits of their efforts have paid off—ARM announced today that it has licensed its Artisan physical IP platform for TSMC's 7nm FinFET process technology to Xilinx, the fabless semiconductor company known for inventing the field programmable gate array (FPGA). Xilinx isn't a new customer by any means. It has partnered with ARM for four process technology generations and has worked with both companies to advance... Read more...
If Windows RT was Microsoft’s first effort to dip its toe with respect to running Windows apps on ARM processors, its latest effort is tantamount to diving in head-first. Microsoft just made a monumental announcement with regards to running Windows on ARM-based processors that power so many of the world's mobile devices. The company has enabled the ability to support the complete Windows 10 ecosystem with x86 emulation on Qualcomm Snapdragon processors -- and yes, it runs very well. Unlike Windows RT, this is a full version of Windows 10 that is compiled to run natively on Qualcomm Snapdragon hardware. That means customers are no longer limited to only running Universal Windows... Read more...
The IoT movement is well under way, for better or worse. On the plus side, we now have access to a wide range of internet-connected devices ranging from smartwatches to webcams to thermostats to even refrigerators. On the downside, these devices can be compromised, leading to massively powerful botnets that have the ability to take cripple websites with DDoS attacks. ARM is well aware of these dangers as we wade deeper into IoT waters, so it has announced new family of Cortex-M processors that will help secure future connected devices. ARM is making a big push to offer more security-related features at the hardware level, and is extending its TrustZone solutions for IoT. “Confidentiality of data... Read more...
It's taken a few years, but Intel has finally started sampling to customers its Stratix 10, the industry's first 14-nanometer field programmable array (FPGA). This is something chip designer Altera tapped Intel to do back in 2013, though it hit delays along the way. Nevertheless, when Intel acquired Altera last year for $16.7 billion, it assured clients and investors that Altera's ARM-based chips would still be developed going forward. Well, here we are. Stratix 10 meshes Intel's 14nm tri-gate process technology with a new architecture called HyperFlex. It features an embedded quad-core 64-bit ARM processor (Cortex-A53), 5.5-million logic elements, and second generation High Bandwidth Memory... Read more...
If you can’t beat ‘em, join ‘em. Intel was an ARM license holder back in the early days of the personal digital assistant (PDA), and found its StrongARM and XScale chips in devices like the HP Compaq iPaq 5450 and other products of that ilk. But Intel jettisoned its ARM division in 2006 to focus on x86 processors, only to see a huge surge in ARM processor deployments with the rise of smartphones a few short years later. Intel tried to counter with its own low-powered, x86-based smartphones SoCs, but its efforts proved futile. Now, Intel is deciding to wade back in to the ARM waters as an ARM licensee. The chip giant will not design and market its own ARM-based designs, but it will offer its mammoth... Read more...
If you currently are in possession of a smartphone (and who isn’t these days), there’s probably close to a 99 percent chance that it’s running on a processor that was originally designed by ARM Holdings. ARM doesn’t actually build the chips that you find in smartphones like Apple’s iPhone 6s or Samsung’s Galaxy S7 Edge; but it does license its processor designs and related IP directly and allows licensees to create their own custom processors using ARM instruction set compatible architectures. A big shakeup is about to happen at ARM, because Japanese powerhouse SoftBank has offered to purchase the British multinational tech company for around $31.4 billion in cash. This lofty price tag represents... Read more...
Over the last few weeks, ARM has revealed a number of details regarding its next-generation mobile processor IP. We posted news on ARM’s 10nm Artemis test chip here, which was manufactured in concert with TSMC, and also have numerous details regarding the upcoming high-performance ARM A73 CPU and Mali G71 GPU cores, due to arrive in premium mobile devices by year’s end.Today, ARM is taking things a step further and introducing another building block for next-gen SoCs (system on a chip), a new video processor codenamed Egil.When ARM’s customers license the company’s technology for their mobile processors, different components (or component configurations) are used to build a chip that targets...
