So did you actually time the test with a stopwatch? Your result looks very much like the time required to complete the final setup in the action as timed by the Photoshop timer function. I don't doubt your new machine is fast, just not this fast.
A 4 core runs the test in 11 seconds and yours runs 1.8 sec?
Why not do a quick video so we can time it our self.
You're exactly right, I did use the Photoshop timer function and as such probably drew a false result. I did that test after completing this one, which produced a more accurate and predictable result.http://ksimonian.com/Blog/2010/02/24/improved-photoshop-benchmark-cpu-speed-test-for-both-mac-pc-free-radial-blur-filter-test/
14.5 seconds to complete your radial blur test. (Note: Photoshop only makes use of one of the two installed GPUs)

I also did the Blackmagic Disk Speed Tests that are already recorded in this forum. If you have any other specific tests you would like performed please let me know.
