Update: We were originally told that the Galaxy S II would be using an NVIDIA Tegra 2 SOC, but have been informed that was incorrect -- the phone will indeed have a dual-core 1GHz Samsung chip, and quite possibly the Exynos. There's also 1GB of RAM.
We were able to spend a little bit of time with the Galaxy S II today, and we can conclusively say that this is one gorgeous device. It shares the Infuse 4G's aspirations as an ultra-thin Android device and arguably shares most of its industrial design elements, but interestingly, the Infuse steps down from 4.5 to 4.3 inches -- either a nod to the fact that 4.5 is too big for a mainstream smartphone, or a sign that the 4.5-inch Super AMOLED Plus component simply isn't ready yet. You totally notice how ridiculously thin the phone is as it rests in your hand, and the effect is amplified by the fact that it's got so much surface area -- the screen-to-edge ratio is off the charts. Though we still prefer the stock Android experience, TouchWiz 4.0 (as it's being called) on top of Gingerbread is clearly Samsung's most refined custom Android skin to date; a new Game Hub in ROM has potential to do battle with Sony's PlayStation Suite and allows developers to bypass the download size limits of the Android Market, but we weren't able to test it on the preproduction unit we were given.
Owing to a lack of time and connectivity, we weren't able to put the phone through a suite of speed tests, but the entire UI felt perfect fast and smooth, a testament to the processor's chops. As at CES, we were blown away by the clarity and brightness of the Super AMOLED Plus display -- picture the already-excellent Super AMOLED technology amped up on steroids, and you'll have a good sense of what we're talking about here. All told, this seems like a great upgrade to the Galaxy S; if anything, we're a little concerned that it's going to be a smidge too big for people that were perfectly happy at the 4-inch tier, but odds are good Samsung will continue to crank out smaller devices for those folks. It'll be on the market in parts of Europe and Asia as soon as this month; no word on North America, but as always, there's little doubt Samsung has some plans in the works.
