Well, I would think Nokia is taking advantage of the features the CPU provides:
http://focus.ti.com/general/docs/wtbu/wtbuproductcontent.tsp?templateId=6123&navigationId=11991&path=templatedata/cm/product/data/omap_1710
such as having a DSP alongside your GPP.

By the way, I'd like to know if there's are benchmarking tools for
GStreamer somewhere, just to know how a certain platform behaves with
GStreamer.
