Comparing processor clocks is just silly. The framebuffer is not stored in L1 cache.

On the Pi, the FB is in shared RAM clocked at 400MHz. RAM probably has a bandwidth of around 250MB/sec (wild ass guess based on parts). If you're driving 1080p, that doesn't leave much bandwidth for anything else. Plus ca change, eh?
