Nokia's CEO Stephen Elop recently claimed that dual- and quad-core chips used in modern smartphones were awaste of battery and weren't necessary for performance. Now Intelhas waded into the debate, saying that support for dual-core chipson Android is so bad it's actually a detriment. According to the Inquirer , Mike Bell, the chipmaker's general manager of the Mobile andCommunications Group explained that data collected during internaltesting suggest Android's thread scheduling just isn't ready tohandle multi-core processors. He stated the results showed thateven Google's latest Android 4.0 release (Ice Cream Sandwich) ondevices with multiple cores offered little benefit and at times waseven detrimental to overall performance. "I've taken a look at the multiple core implementations in themarket, and frankly, in a thermal and/or power constrainedenvironment – what has been implemented – it isn'tobvious to me you really get the advantage for the size and thecost of what's going into that part," said Bell. "The wayit's implemented right now, Android does not make as effective useof multiple cores as it could, and I think – frankly –some of this work could be done by the vendors who create the SoCs,but they just haven"t bothered to do it." Bell believes chipmakers haven't done enough to optimize Androidfor dual- and quad-core phones. This despite advertising campaignspromoting such devices as considerably more powerful, in what hasalmost become a competition to offer the highest number ofprocessing cores for eager consumers. While Bell didn't point the finger at any particular chip, he didpoint out that internal testing of Android handsets had shown thatchips with multiple cores at times ran slower than single-coreimplementations. "If you are in a non-power constrained case, I think multiplecores make a lot of sense because you can run the cores full out,you can actually heavily load them and/or if the operating systemhas a good thread scheduler. A lot of stuff we are dealing with,thread scheduling and thread affinity, isn't there yet and on topof that, largely when the operating system goes to do a singletask, a lot of other stuff stops. So as we move to multiple cores,we're actually putting a lot of investment into software to fix thescheduler and fix the threading so if we do multi-core products itactually takes advantage of it," Bell further commented.
