I finally found one relevant and up to date benchmark, this review compares the performance of the Clarkdale IGP to the X4500 in Quake 4:
(No mention of which timedemo was run though.)
In 1024x768 the X4500 averaged 17.65 fps in Windows. For comparison I ran the Phoronix "pts" demo, and the built-in "id_perftest" with the same settings. (Using a git snapshot from a couple of weeks ago, I doubt there's much of a difference to Mesa 7.8).
pts: 21.4 fps
id_perftest: 13 fps
Between the two, I guess performance is roughly the same as on Windows.
