Lies, Damn Lies, and Statistics
Cherry picking favorable statistics has long been a marketing ploy. These bench marks ignore one important bottleneck for many tasks; the user's fat fingers. AMD apparently decided that certain tasks were not critical in most situations were a laptop is unplugged and extending battery life might be much appreciated. The tasks Chipzilla is ranting about strike me as either a task that is not what most will be doing while mobile or if they are time is not as critical. But this is typical marketing BS.
