Intel is certainly no stranger to making wild claims for its ownproducts and against the competition. Mike Bell, general manager of Intel's mobile communications group,most recently tossed a claim at Google's Android, which is typically powered by rivalRISC-based ARM processors in nearly 99.9% of smartphones andtablets. According to Bell, Android's thread scheduler simply isn't readyfor multicore processors. Why, you ask? Well, Bell says the resultsof internal Intel testing illustrate that a second core is actuallya detriment to performance in some cases. Some Android smartphone makers, says Bell, should have thoughtabout this last year when they launched smartphones with dual coreprocessors - before the Android operating system was actuallycapable of supporting a second core. Indeed, support for dual coreprocessors didn't officially surface until Android 2.3.4 launched in April of last year. "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," Bell opined. "A lot of stuff we are dealing with, thread scheduling andthread affinity, isn"t there yet and on top of that, largelywhen the operating system goes to do a single task, a lot of otherstuff stops. So as we move to multiple cores, we"re actuallyputting a lot of investment into software to fix the scheduler andfix the threading so if we do multi-core products it actually takesadvantage of it." As most claims of performance leveled against competitors go,Intel's is pretty typical insofar as the chipmaker has offered nodetails on what device they tested, or how exactly they tested thedevice to support its claims. Of course, that hasn't stopped Bellfrom claiming that Intel's internal testing showed multi-coreimplementations run slower than a single core on Android. "If you take a look a lot of handsets on the market, when youturn on the second core or having the second core there [on die],the [current] leakage is high enough and their power threshold islow enough because of the size of the case that it isn"tentirely clear you get much of a benefit to turning the second coreon," he explained. "We ran our own numbers and [in] some of the use caseswe"ve seen, having a second core is actually a detriment,because of the way some of the people have not implemented theirthread scheduling. As noted above, Bell also pointed an accusing finger at Androiddevice makers, in addition to criticizing Android. "The way it"s implemented right now, Android does notmake as effective use of multiple cores as it could, and I think– frankly – some of this work could be done by thevendors who create the SoCs, but they just haven"t botheredto do it," he added.
