Mantle to me looks like a potential game changer. Though I won't get excited until I see what it can do and if it becomes more wide-spread. It is going to be in
THE biggest PC game release of the year and many EA AAA titles going forward.
If you bothered to read what True Audio does you will see it is way beyond some positional 3D audio effects. Rroff said it very well in this post.

You asked for features that AMD have that Nvidia don't. I gave you two and you are essentially saying "they don't count because I don't like them". You don't think they are good features, fine, I and many others like what they
potentially bring as desirable features.
Mantle already changed the gaming landscape.
Console for GCN and amd is here for 7 or so years.
Games are made to console for many developers first and then ported over.
Mantle support to the gameengines and the developer dont need to do much due to the gameengine developer like dice handles that.
Mantle is a big thing, much more than people realize.
Trueaudio is superb, how much support for it to be is another matter.
BF4 wont use it but maybe BF5.
I for one seek better sound due to gaming immersion really goes off with it but trueaudio isnt a big gamechanger, Mantle is.
Mantle is an api it tells the software how it should run on the card, if the software has less aka fewer instructions to make things run it runs faster and put more work to the gpu and if its coded to the gpu tech like GCN, cpu overhead goes away and the bottlenecks happens elsewhere.
This IMO is done to even the gaming playfield for AMD
vs Intel not Nvidia as AMD already is crushing Nvidia in every segment of value with price/performance with the new/rebranded R series.
AMD sells both
cpu and
gpu, and imagine if Mantle allows a 8core 8350 to run as good or better than intels 4930k then you have a great choice what to buy, buy amd cpu and gpu for a better gaming experience. IMO it what AMD is trying to do and if they succeed we will find out.
I believe someone at amd thought about who buys things in a family and making software to even the playfield with Mantle is a good one especially since the gamedevelopers like Johan Andersson at dice asked for it.
