I would say that an A8-4500 running at 2.8GHz would be about equal to an Intel mobile CPU running at 2.2GHz - 2.3GHz, but that's a rough estimate. Individual tasks can vary though. The A8-4500 is a quad core CPU while most mobile Intel CPUs that would compete with the A8-4500 on price would be dual core CPUs.
And you knew which processor was fastest (more or less) by its numerical clock-speed rating. These days it's a lot trickier. Only hard-core techies (and those with the patience to search in Google) know the difference between, say, an AMD A4-3305M and an Intel Core i3-2350M.
