A:Answer CPU-z validation shows that this processor nominally tops out at 1.5Ghz for everyday use, with most time spent well below that unless you're actually taxing it. The maximum listed frequency is 2208Mhz (2.2Ghz) so don't worry, the technical specifications are completely accurate. Bestbuy just isn't that great with details, sadly.
