There isn't much detail and there aren't any benchmarks, but Charlie Demerjian, a.k.a. Groo, is very impressed with what he has seen so far.
Multimedia content creation has been the one area where Pentium 4 holds out against Pentium M. If it wasn't for the lack of 64-bit support, I think Pentium M would finish off Pentium 4 for good.The thing that should get you excited is that Yonah should be a multimedia monster, it has the full compliment of SSE1/2/3 on board, and they are vastly improved over Dothan. Several other instructions have been tweaked for lower latency and improved performance, resulting in a monster chip for multimedia. It may even give the Pentium 4 a run for its money in this field, but no hard numbers have surfaced yet.
Unfortunately, that will have to wait until late 2006 early 2007, when Merom ships.
