    An intro to all things ARM
    How ARM created an ecosystem that upended the market

    With the rise of smartphones and tablets, the arc of consumer computing has been radically altered. Now, ARM processors power some of the computers many of us like the most: ridiculously powerful smartphones, tablets whose stunning displays are wildly superior to the average PC's, and e-readers so well-suited for their roles that they're capable of inspiring poetry.

    ARM's fortunes have risen, too—as have the firm's ambitions.

    ARM lays the foundation for a data center invasion
    Partners line up to help make it happen

    Most ARM licensees aren't likely to challenge Intel by attempting to take on its potent Xeon processors head to head, like AMD may well do with its K12 core. They can, however, potentially gain a foothold in the lucrative enterprise market by tailoring ARM-compatible SoCs for specific classes of workloads. An old axiom of computing says that custom-designed hardware will inevitably be more efficient and cost-effective at a given job than a brute-force, general-purpose solution. Not every job demands the fastest processing core. If ARM's partners can build SoCs that efficiently handle workloads that are, for instance, more I/O-bound than compute bound, then they can win business away from Intel without matching Xeon stride for stride in every respect.
    In doing so, ARM and its customers could very well lower the cost of computing at a rate faster than Intel's famed Moore's Law, and we could see an expansion of the number of viable players in the business of building server-class silicon.

    ARM Preps Second-Generation “Artemis” and “Maya” 64-Bit ARMv8-A Offerings.
    ARM Readies 64-Bit Cores for Non-Traditional Applications

    ARM Holdings said on Tuesday that it is developing multiple IP solutions based on the 64-bit ARMv8 instruction set. The company has already begun to license its second-generation 64-bit cores and will address new markets with other ARMv8 architecture-based solutions in the future.

    State of the Part: SoC Manufacturers

    Depending on whom you wish to include/exclude, there are anywhere from four to eight SoC manufacturers still in the game, with three of them mostly catering to the budget sector. We could also include ARM as a company, but since they don't really manufacture any parts we'll leave that for a separate article.

    Cortex-M7 Launches: Embedded, IoT and Wearables

    If you are not familiar with the M and R series processors from ARM, I don’t blame you. These microcontroller processors don’t receive quite the coverage as A series application processors like the A7, A9, A15, A53 and A57 do. Considering my own heritage learning about PC technology, this is understandable. I always wanted to learn about the latest processors from AMD and Intel as these most directly related to my productivity and entertainment. However, if the smartphone wave was any indication, the next decade of productivity and entertainment might come from processors we don’t expect or even know about.

    MediaTek reports record quarterly sales

    Mobile chip maker MediaTek has reported another record quarter. The company posted $1.98 billion in consolidated results for Q3, up 6.1 percent sequentially. September saw a slight dip, with shipments falling to the lowest point since June. Analysts blame the decline on seasonal trends.

    ARM just introduced the processors that'll power smartphones in 2016

    ARM has just released a suite of new CPU and GPU designs that'll make 2016's mobile devices faster and — more importantly — more power-efficient. The core of the new processors ARM is introducing is the new Cortex-A72 mobile CPU — it's rated at 3.5 times faster than the current generation Cortex-A15 that started shipping in late 2012 in the Nexus 10, and it uses 75 percent less energy than the A15 under identical workloads.

    The new A72 can also be paired with ARM's existing Cortex-A53 processor in something the company calls its big.LITTLE configuration — this saves the A72 for more heavy lifting while the lower power A53 handles most of the day-to-day tasks. When running in that configuration, ARM says that'll supply an additional 40 to 60 percent power reduction on average.

    The Qualcomm reign on smartphones and tablets is almost over; all hail Mediatek
    ...
    Qualcomm was beyond MediaTek to the point where it was almost a joke. The MediaTek cavemen were barely experimenting with their first single-core 1 Ghz chipsets while Qualcomm was releasing the dual-core 1.7 Ghz Snapdragon S3 Scorpion. By the time the dodos at MediaTek had finally released their first dual-core 1 Ghz processor— the MT6577— it was already 2012. Just two, no, three years ago. What was Qualcomm doing at this point? Aside from running circles around MediaTek , they had released their first quad-core Snapdragon S4 SoC. MediaTek who?

    Enter 2013. ...

    Understanding Qualcomm's Snapdragon 810: Performance Preview

    While we can dance around the issue, it’s impossible to have any real discussion about Snapdragon 810 without addressing the flurry of rumors that have surrounded this SoC. There have been rumors of overheating, delays, and all sorts of defects. In light of this, the Snapdragon 810 and its performance has been the subject of intense interest. In order to learn more, we recently met with Qualcomm to do a deep dive on the Snapdragon 810 and properly benchmark it for comparison against other SoCs.

    ARM Reveals Cortex-A72 Architecture Details

    ​Today in London as part of ARM's TechDay 2015 event we had the pleasure to get a better insight into ARM's new Cortex-A72 CPU. ARM had announced the Cortex-A72 in the beginning of February - leaving a lot of questions to be asked and sense of mystery in the air. The Cortex-A72 is a direct successor to the Cortex-A57 - taking the predecessor as a baseline in order to iterate and improve it.

    relativamente ao aquecimento do s810. pelo que vi corriam por exemplo o antutu e começava em 55 mil pontos(htc m9 antes do update que melhora o problema de aquecimento) e iam correndo varias vezes e à sexta vez que corriam o teste ja só fazia 43 mil pontos. já era pior que a performance do S805 utilizado no note4.

    quanto ao GS6 eu testei e tambem tive resultados a descer. comecei com 71 mil pontos, depois 69 mil (segundo teste) e cheguei a sexta vez que corria o teste seguido a alcançar 67500. o telemovel gs6 também aquece bastante na parte de trás principalmente quando estamos a gravar em 4k aquece mais a filmar que a correr varias vezes o antutu. pelo menos nos testes iniciais que lhe fiz

    Morgan Stanley tests ARM on its datacentres

    Bert Shen, vice president of technology business development at the financial services firm told Computerworld AppliedMicro showed it a benchmark that compelled it to take a closer look at ARM.

    "They ran a very relevant columnar database benchmark for us and got a 5x performance improvement per rack compared to an Intel Haswell EP solution. We thought this was about the right time to bring in a proof of concept.”
