Performance is quoted as being twice that of Mobility Radeon 9700, something I'm inclined to mostly agree with, given their relative architectures. So to sum up, in the absence of any samples or comparisons with NVIDIA's upcoming announcements in the same sector (Seiko would be proud), Mobility Radeon X700 has some serious on-paper promise, based on the presented information ATI have given to press for today.
