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.

    I can't see how wasting cycles on implanting an x86/x64 instruction set would be of much use commercially. I don't get the impression that many ARM manufacturers have any interest in trying to beat Intel on its own platform.

  • Now that one person is doing it, everyone is going to have to do it. It's going to be difficult selling a 32-bit processor when the guy across the street is selling a 64-bit one.

    There's a lot more reason to go 64 bit than that. The biggest is that it's not going to be long before smartphones and tablets have > 3 GiB RAM. Yeah, there are all sorts of workarounds you can use to access larger amounts of RAM with 32-bit pointers, but it's much nicer to have a flat address space, including plenty of address space for memory-mapped devices. Granted that we're probably a couple of years away from needing 64 bits, but it's coming, fast.
