Intel / AMD have a 4-wide decoder, of which can be a 6-wide decoder if executing out of the uOp cache.
Apple just went with an 8-wide decoder, surprising a bunch of people. There's not much difference between 4-wide and 8-wide, aside from Apple deciding that such a wide single-core unit was worthwhile.
That depends on how many execution units it has to play with, although I guess the bottleneck at that point could end up being the length of a predictable flow.
