Our first interactions with Samsung's Exynos 4 Quad are promising, but there's still much more to understand. Samsung clearly used 32nm as a means to higher GPU clock speeds, which in turn gives us much better GPU performance. The big unknown, as always, is power consumption. Based on what we've seen thus far from Samsung's 32nm LP process in Apple's iPad 2,4 (review forthcoming), Exynos 4 Quad should be a pretty good step forward in the power department as well.
As soon as we can get our hands on final hardware you can expect a full review of the Galaxy S III, including power and battery life analysis.
Initial reactions to the Galaxy S III announcement seemed almost disappointing, however stay tuned for our hands on impressions of the device as well as even more depth/detail on the hardware platform - you may be surprised.
