Qualcomm Announces Next-Gen Snapdragon 808 and 810 SoCs 47

MojoKid (1002251) writes "Qualcomm has announced two fundamentally new chips today with updated CPU cores as well as Qualcomm's new Adreno 400-class GPU. The Snapdragon 808 and the Snapdragon 810 have been unveiled with a host of new architectural enhancements. The Snapdragon 810 will be the highest-end solution, with a quad-core ARM Cortex-A57 paired alongside four low-power Cortex-A53 cores.

The Snapdragon 808 will also use a big.Little design, but the core layouts will be asymmetric — two Cortex-A57's paired with four Cortex-A53's. The Cortex-A57 is, by all accounts, an extremely capable processor — which means a pair of them in a dual-core configuration should be more than capable of driving a high-end smartphone. Both SoC's will use a 20nm radio and a 28nm RF transceiver. That's a major step forward for Qualcomm (most RF today is built on 40nm). RF circuits typically lag behind digital logic by at least one process node. Given that RF currently accounts for some 15% of the total area and 30-40% of the PCB, the benefits of moving to a smaller manufacturing process for the RF circuit are significant."
To clarify, the 810 can use a combination of the Cortex-A57 and Cortex-A53 cores so a single task that needs a lot of power won't cause as large of a power jump. All of the chips are 64-bit ARM too.

    So does this finally mean we'll get Simultaneous voice and LTE/SVDO back? Because all the current generation Qualcomm processors lack dual radio paths for some reason, this despite the fact that the previous generation had it. I have to assume it's because they used so much power/transistor budget on 'more cores!!!!' that they didn't have room for an RF design to accommodate features that are actually useful.

      64-bit ARM and support for simultaneous voice and LTE/SVDO are completely different things.

      The 64-bit ARM cores are application processors (AP). They do not control the modem (that can be part of the SoC together with the AP or an external component): Qualcomm modems have nifty internally developed (and publicly documented) a VLIW CPU called "Hexagon" that offers DSP-like instructions to control the modem. Some modems have two, and another Hexagon is used to process audio and cal also run user provided applications. You can find some information here http://en.wikipedia.org/wiki/Q... [wikipedia.org] and a lot more is linked.

      And even this has nothing to do with dual radios. They are independent things.

The Dijkstra workload is the only real regression. That test in particular appears to be very pointer heavy, and the increase in

        So these cores with the arm V8 architecture add:
        • More registers (16->32)
        • DP SIMD
        • New instructions for crypto

        Well, since you cannot pick the gpu and since qualcomm couples those CPU with their Adreno (scrambled letters from "Radeon") GPUs I think it is a valid question, because it is possible that a dev-boards might use those cpus/gpus or it will be helpfull for the guys at AOSP to have an oss stack.

      They could pair the cores with 8-core TI DSP in order to mimize blobs (the a simple framebuffer and an A/D would be enough to have video/audio).

    I think this may not be enough for a smartphone. After all, it's not for making phone calls. Right? It's for viewing ads. The more the better for all of us.

  • I really don't 100% get this big.little architecture.

    The idea of having a weak but low power core capable of running all the basic functions and driving the GPU is reasonably obvious. I get that. I get the idea of having it backed by 4 big fast cores which can be switched on when a task overloads the little CPU.

    But why have 4 little CPUs?

      The idea of the "little" part of BIG.little is that a device can be much more power efficient. While the big cores (Cortex-A57) can do the heavy processing power, for lower CPU requirements the little cores (Cortex-A53) will suffice and the big cores will be off to save power.

      • Sorry, I wasn't clear.

        Why have more than 1 little CPU. If you have something intense enough to use 4, why not just fire up one big CPU?
