Maybe, maybe not. There are exactly two hardware configurations for Ipads(and less than a dozen if you consider iPhones as well). The abstractions in the OS can be much thinner and more specialized to what is required to get good performance out of the hardware. For the PC there is much larger variation so the abstraction layers have more ground to cover. Though I have to agree with you, it seems performance is rather low on the feature list.
