Intel claims Android is not ready for multi-core processors
Intel, one of the newest chipmakers to enter the Android scene, claimed that rival chip vendors have not done enough to optimize Android for multi-core processors, The Inquirer reported. While the majority of ARM-based vendors are focusing on dual- and quad-core processors, Intel has just entered the Android market with its single-core Medfield Atom processor. Intel’s general manager of mobile and communications Mike Bell recently claimed that Android simply isn’t ready for multi-core processors, despite having supported multi-core chips since Android 2.3.4, and noted that internal testing had shown that multi-core chips sometimes run slower than single-core models.
“If you take a look a lot of handsets on the market, when you turn on the second core or having the second core there, the [current] leakage is high enough and their power threshold is low enough because of the size of the case that it isn’t entirely clear you get much of a benefit to turning the second core on,” Bell claimed. “We ran our own numbers and some of the use cases we’ve seen, having a second core is actually a detriment, because of the way some of the people have not implemented their thread scheduling.”
Bell went on to say that he has “taken a look at the multiple core implementations in the market, and frankly, in a thermal and/or power constrained environment – what has been implemented – it isn’t obvious to me you really get the advantage for the size and the cost of what’s going into that part.”
