    A15 is a power hog

    There rumblings going about that big.Little is a failed concept. This can turn into big news. Some comments I found:

    There have been many research projects that have looked at combining Atom and "big cores" e.g. Ivy Bridge and Haswell as well as ARM processors to handle low-level OS functions and some applications while the bigger cores are sleeping. In fact, I think Dell had a laptop that had both "ARM & Intel Inside" to do roughly the same thing.
    The A15 is a hot, complex chip that's not particularly performant for the power nor does it yield particularly well. That A7 companion chip and the entire Big.Little concept is a tacit admission of that regrettable reality.
    ------------------------
    I'll ask around but I can tell you that many of the A15 licensees are greatly disappointed with its perf/watt and associated manufacturability issues.
    -----------------------
    a Dual core A15 @ 2GHz in our lab is consuming 4W. Mind you, this is just the CPU Cores. When we add the Graphics, Video and IOs, you are looking at around 6-7W. ARM is in big trouble. This big.Little is just a hog-wash. Unless we see this from a 3rd party, I cant believe 50% improvement. ARM CEO can say Power this and power that, but his ARM Cores are getting worse by day.

    • "This big.Little is just a hog-wash."

      [Yep, the kind of band-aide, bubble gum and bailing wire ARM is having to resort to since it doesn't have state-of-the-art fabrication. The failure of the fabless model in providing enough money for R&D and CapEx is finally coming home to roost. It's the end of the ARM era...]

    • ARM Servers - UDX1
      Ultra low power and high server density for hyperscale computing

      Power and cooling are the biggest facility challenges for most data centers. For typical cloud computing, web 2.0 and big data applications that are based on scale-out architectures high server densities and low power consumption are crucial to achieving low TCO. Based on Calxeda’s EnergyCore SoCs the UDX1 offers a ultra low power envelope of 5W per server and a server density of up to 48 servers in a 2U form factor. Workloads that up to this point required racks of conventional systems can now be handled by a group of servers in a single physical unit.

      The UDX1 features a modular architecture. A single module contains four server SoCs with four cores per SoC. The UDX1 can accommodate up to 12 modules. Calxeda’s SoC architecture integrates the entire system logic on a single die: ARM9 quad core processors including the Neon SIMD engine, L2 cache, BMC, SATA disk drive and memory controllers. Moreover each server features an on-chip 10 Gb Ethernet switch fabric that can scale out to up to 4,096 servers without the need for any additional external switches.

      The ultra low power envelope of the UDX1 is achieved through a separate, dedicated processor on each EnergyCore™ SoC that monitors and controls energy consumption in real-time. For both single-node and cluster-wide management, the embedded management engine is responsible for:

      Automated power management for 12 power domains per SoC
      Cluster-aware fabric management for power and routing optimizations
      Remote systems management interfaces
      The UDX1 ships with Canonical's Ubuntu or Redhat Fedora pre-installed on every server.

      • Intel Delivers the World's First 6-Watt Server-Class Processor

        Several Equipment Makers Building Microservers, Storage and Networking Systems Based on 64-bit Intel® Atom™ Processor S1200 Product Family

        NEWS HIGHLIGHTS

        Intel® Atom™ processor S1200 server system on-chip hits lower-power levels, and includes key features such as error code correction, 64-bit support, and virtualization technologies required for use inside data centers.
        More than 20 low-power designs including microservers, storage and networking systems use the Intel Atom processor S1200 family.
        SANTA CLARA, Calif.--(BUSINESS WIRE)--Intel Corporation introduced the Intel® Atom™ processor S1200 product family today, delivering the world's first low-power, 64-bit server-class system-on-chip (SoC) for high-density microservers, as well as a new class of energy-efficient storage and networking systems. The energy-sipping, industrial-strength microprocessor features essential capabilities to achieve server-class reliability, manageability and cost effectiveness.

        "HP servers power many of those organizations, and the Intel Atom processor S1200 will be instrumental as we develop the next wave of application-defined computing to dramatically reduce cost and energy use for our customers."
        "The data center continues to evolve into unique segments and Intel continues to be a leader in these transitions," said Diane Bryant, vice president and general manager of the Datacenter and Connected Systems Group at Intel. "We recognized several years ago the need for a new breed of high-density, energy-efficient servers and other datacenter equipment. Today, we are delivering the industry's only 6-watt1 SoC that has key datacenter features, continuing our commitment to help lead these segments."

        As public clouds continue to grow, the opportunity to transform companies providing dedicated hosting, content delivery or front-end Web servers are also growing. Hig

    • All this is nice to know but all I give a #$%$ about is about making money and I hope INTC goes to $5 a share and watch me back up the truck.....the financials tell the tell, they have a mountain of cash and doing buy backs of shares, the only problem I see is Warren Buffett in that why did he sell?

    • This explains why qualcomm and apple have both stayed clear of this power hog chip!
