Not convinced

By | February 27, 2012
Does Android OS support Quad-core processors? With optimizations for custom-compiled code, like the gcc flags? Are there apps out there (other than gaming) for which this would make sense? Or is it just wasted processing power, since all I want to do is access the web, use GPS, and maybe on occasion phone or SMS?

… If not, it seems like this is just wasted processing power.

HiSilicon K3V2 Quad-core 40nm ARM Cortex-A9 unveiled at #mwc12
Huawei’s new high performance Diamond series phone uses the new HiSilicon K3V2 Quad-core 40nm ARM Cortex-A9, with 64bit latest/fastest DDR2-for-smartphone memory bandwidth, they claim it has the worlds fastest ARM performance. Here’s an interview with the chief architect on the processor. I try to ask him about the performance, memory bandwidth, GPU, processor design. The K3V2 is made at the TSMC foundry. He has a team of about 500 processor engineers working for him in Shanghai to design this processor. He claims HiSilicon’s cache coherent interconnect design makes it superior to designs such as Tegra3, HiSilicon does not need that “companion core” as they claim to have designed the Quad-core in “the correct way”. HiSilicon has a GPU design partner which I have not heard them mention who it might be. In 6-12 months, HiSilicon is likely to release an ARM Cortex-A15 design on 28nm and also to upgrade their ARM Cortex-A9 designs to 28nm “when 28nm is ready”, for now, he says that the 28nm process manufacturing has too much leakage.

    I've heard talk of Android tablets (and perhaps even phones) as striving to compete with hand-held gaming consoles.

    But, frankly, I know individuals who would very much like to replace their PC with a tablet, and that simply won't be possible without faster tablets and larger hard drives.

    There's the proposed Ubuntu build which allows your android to connect to a docking station and then be used in place of a desktop. If that was there, would you make the transition?

    Well designed software does a lot of work in "background" these days. This software will benefit by adding more cores.
    Since android offers a fairly high level API for the GUI it can do a good job in paralellizing the users code.

    Android is built to scale to as many processors as available. My question though, is what is the point? With the exception of certain games, most apps are built to play to the lowest common denominator. And for god's sakes, these are phones! Are there really people out there running custom apps to do scientific work on a phone? I'm a techie and a geek, and I love being able to brag on specs, but I have a dual-core phone now, and I really wonder why. While I do enjoy the extra performance and smoothness, the app developers are so far behind that a lot of the games I was running on my old phone I can't even install now, or they don't function properly. Most of this is due to the 720p screen I have on my Rezound, but how does it benefit me to have a high-spec phone when 60% of my apps are no longer compatible?
