Well according to scuttlebutt the A64 wont be released at under 2Ghz, so its either a 2.0, 2.2 or 2.4Ghz part.
As for unblurring its theoretically possible.
If a common blur tool from a well known imaging package is used it would be concievable to work out a reverse process...
But of course you would need to know:
A. the program
B. the blur method
C. the precise regoin blured
D. to what extent blur was applied, was it applied multiple times and also what direction.
