Yup, it will keep your hands nice and warm in this cold weather!
There are some nvidia games that you can get, which are pretty decent and special versions of games i.e. better graphics for tegra devices but apart from that, not really anything at all.
Advantages of the S4 over tegra 3:
- More performance per core, which is better than having an additional 2 cores as android/apps/tasks don't fully utilise the potential of dual core let alone quad. When I compare my S to the X and GS 3, I notice that things are a lot snappier/more instant i.e. loading the gallery thumbnails, loading games/levels, apps, rendering maps etc. Of course, better software/driver optimisation would be a big factor here as well.
I haven't used a X with JB yet, so that difference might not be as noticeable any more, especially if the benchmarks are anything to go by. People who have got the update so far have said the improvement in performance is massive.
Saying that with all handsets running JB (especially the X), it isn't exactly an area of great concern.
- Amazing power efficiency thus better battery life
Again, the X has supposedly improved by quite a bit with the JB update, but it still wouldn't be as good as the XL.
- Doesn't get anywhere as hot or heat up as quickly as other chipsets, as we all know on this forum, over heating components can cause many problems.
- the audio on the XL (uses the same audio codec as the S) would also be better than the X
- smoother 1080P recording
