Qualcomm's Snapdragon 835 is Its First 10-Nanometer SoC (engadget.com)

An anonymous reader writes: Chipset maker Qualcomm has unveiled its next-gen Snapdragon 835 flagship SOC and confirmed rumors that it will be built by Samsung using its 10-nanometer FinFET process. Compared to the current 14-nanometer Snapdragon 821 (also built by Samsung), the new CPU packs 30 percent more parts into the same space, yielding 27 percent better performance while drawing up to 40 percent less power, the company says. It also improved the design, which will yield "significant" improvements to battery life. The new chip comes with Quick Charge 4, which supports 20 percent faster charging than Qualcomm's last-gen tech. That, the company says, will give you up to five hours of extra battery life with just a five-minute charge. In just 15 minutes, it'll give Snapdragon 835 phones a half-full battery.

    27% faster than the 821 which was 10% faster than the 820. Moore's law is alive and well I see.

      How is Moores Law still going if it is no longer doubling as fast as it used to? That was the whole point of Moores Law. Transistor count hasn't doubled in a long time.

    How long is this thing supposed to run? Most smartphones only run like 3 hours tops if your actively using the screen.

    screens and LTE radio's are the 2 biggest drains on battery life in mobile devices. A more efficient SOC is not going to do anything to change that

  3. Quick Charge? by Game+Genie · · Score: 2

    Okay, 5W@500mA is horrible, and we needed proprietary solutions to get around this on USB 2.0, but now that there is actually a standard (USB-C Power Delivery) why are they still messing around with this silliness?

    Right, because scale isn't relevant here.

    You still have to get the power into the Lithium cells quickly. The Power Management Module(PMM) inside the CPU regulates the rate at which power enters/leaves the lithium cells. This Snapdragon supports taking in larger amounts of power and shoving it into lithium cells faster.

    Trust me when I say this, Apple iPhones aren't all that special. Given the "Ingress" test is the most brutal of "Performance" testing, iPhones do not perform all that much better than similarly equipped Android phones.

    The iPhone people I know do not spend significant amounts of time on screen, except when watching movies.

    tldr: sorry, good intentions but you're wrong, I'm right, etc.

    The way the main SOC (ie the snapdragon SOC) decides to power devices on/off (such as radio) and the efficiency of their regulators does change battery life significantly though when the device is not under active use.

    But in addition to that, the way the SOC manages it's own cores, and the way the core are built very significantly changes battery life under active use.

    But you don't have to believe me, because Samsung builds the SAME phone with 2 chipsets: the galaxy S7/S7Edge comes with the same specs and either a Snapdragon 802 from Qcom or an Exynos from Samsung themselves.
    The Exynos Galaxy S7 Edge lasts 2-3 HOURS more than than the Snapdragon version, under active use.

    Wow, this is just unbelievable. A 10nm die. It is so amazing how far we have come in just 30 years. I am truly impressed and amazed that we can carry around a 2Ghz Quad core in our pocket that is a fully functional computer. It is truly impressive, congratulations everyone!

    I'm not missing anything, it's just that 1) the RX pre-amplifier is a low power device and 2) replacing analog processing with digital enables to lower power consumption in step with digital fabrication process improvements, so if you, for example, come up with ways of improving communication that lower energy per bit transferred in the analog part but require more processing in the digital part (improved self-correcting codes, for example), then digital process improvements may be a prerequisite for such improvements.
