I just want to confirm what I've read up on this (which I can only find one real source)

I have two Turtle Beach Vortex2 cards. One has AU8830 written on the chip and the other has AU8830A2.

From what I have read, the AU8830A2 is an older version Vortex2 chip and has lower performance than the newer AU8830 chip.

True or false?

Yes, the later chip revision has slightly lower CPU utilization and thus better performance; several reviews found a measurable difference there.

-Revision A2, on the Diamond MX300 among others, pictured here: https://upload.wikimedia.org/wikipedia/common … Sound_MX300.jpg
-Revision B0, on the Aureal SQ2500, the top card here: http://i.imgur.com/veJh9j4.jpg (Note the bottom card - Vortex2 SuperQuad or SQ2500 Optical - looks like an example of an A2 revision using the later marking scheme, so "AU8830 vs. AU8830A2" may not be a sure indication of revision.)

Not very consequential. The rest of the board is as important in practice, in my opinion. There are test graphs showing the Diamond MX300 producing a better analog response than Aureal's reference A2 revision boards; just where the later revision equipped boards or Turtle Beach designs place is unknown.
