you could find out where time is being spent using oprofile, but it's not really surprising that 3dmark is the same speed, when time is going to be spent in video drivers or the applications own code rather than in win32 calls where the time is already going to be minimal or problematic by design or misuse by an application.
What you could do as a benchmark is time a Wine test run for icc compiled Wine vs gcc compiled.
