It's about the powervr gpu and the fact that the snapdragon version on the gs3 didn't run as smoothly as the Exynos version, despite it having 2gb of ram.
That was due to Samsung's poor optimisation with the chipset, the one XL/S, razr HD/M are great performers in everything, my one S is just as fast/smooth as an exynos GS 3, very little difference between the two, in some areas the one S is smoother/faster, in some areas the GS 3 is faster/smoother, overall I find my S to be "snappier" though, probably due to it having more performance per core (same animations timings etc.)
Software/driver optimisation is the most important thing, without that then no matter how good the hardware is, the phone UI etc. will not be fast/smooth.
If the S600 is being used in a lot more places, I imagine that Samsung will put more effort into it this time.
Besides, this snapdragon chipset has a lot more powerful GPU than the one which was being used in the USA GS 3.
To the octo complainers....
1) It is not a true octocore processor, it's two quad cores stuck together. The Exynos 5 will never use all 8 cores on the same task, hence it is not an octocore processor. Reminds me of the old Jaguar games system that claimed to be 64 bit when in fact it was 2 separate 32 bit chips on the same board.
2) More <> better. Even in 2013 games and application developers are still struggling to equally distribute the work across X number of cores. The vast majority of apps will work better on a higher clocked quad core (like the snappie) than a lower cloked 'octo' -core (like the Exynos).
3) The snapdrgaon is much better for rooters given the open source nature of it. Exynos refuse to give devs the source for their processor.
4) An octocore processor is overkill on a high end PC, so it is all but pointless in a phone right now.
Well put.
Many apps/tasks still don't even utilise a good dual core chip properly let alone quad yet. Although I think Samsung have tweaked touchwiz/android a lot more so that it utilises the extra cores a lot better, however, with 3rd party apps, developers will also have to do something to take advantage of that system I think.
In theory the more cores the better i.e. multi-tasking and battery life but we have to have better software optimisation throughout first in order to really achieve the potential of quad/octo etc.
Another advantage of snapdragon, you are less likely to have problems with apps i.e. a lot of apps were force closing or had some form of a problem on the gs 3 when it was first released. Plus they will be better optimised for snapdragon chipset due to the majority of phones using snapdragon chips (especially when the nexus 4 is using the s4 pro)
If people aren't going to be getting the GS 4 due to it not using exynos chipset then the phone really mustn't be that special in the first place
