There's an excellent comparison of the capabilities of both
micro-architectures (along with P4 Prescott) in the linked article at Real
World Tech:

The pictures there clearly show the dispatch and port bottlenecks of each
implementation.

Is there any word yet on what SSE4 will contain? All I could find in the realworldtech article was this:


These new SSE4 instructions are not terribly interesting; there will be some performance gains, but nothing like the improvements from SSE2.

Even if they aren't "terribly interesting" it would still be nice to know what those new instructions are.

That has not been announced.

Let me caution everyone involved that most of the people writing about SSE4 usually don't have much experience doing vector programming and probably can't tell interesting from waste of time. They also don't have any inside information from Intel -- if they did, they'd be under NDA. Typically these authors are careful to differentiate speculation from announced fact* so watch out for the hedging.
