    "reduced standby power by 3 orders of magnitude. I asked Broadcom to give me a realistic estimate of power consumption - BCM4330 in full Rx mode consumes around 68mA, BCM4334 consumes 36mA at the same voltage"

    Sorry to be picky, but 3 orders of magnitude should be 10^3 or 1.000 times lower. So from 68mA it would be 0.068mA or 6.8uA... which is not the case.

    Standby != Full RX mode.

    I'd imagine the standby power isn't something they want to reveal yet.

    This is exactly the case, I got numbers for full receive mode (which has the frontend lit up), but was also told that standby is even lower.

    Reducing power consumption (especially as much as they claim) is good, but I wouldn't design a device using this chip. Put simply, everything about VideoCore is behind a NDA making it harder to work with and optimize for than the competitors. Reply

    They announced their A9 based SoCs, but this story isn't about those (still working on it) but rather the WLAN combo chips and 802.11ac products shown today.
