In reference to Alex Dobie's recent review:
Speed:
In multithreaded situations, yes, the Galaxy SIII international will faster than the Evo LTE/One X. However, almost nothing in practical use, especially on a phone, will take advantage of that. *Maybe* a handful of very intense games, especially since the SIII's graphics coprocessor will be faster under most all situations.
In all other cases, which is what people will see and feel the most, the S4 processor's cores used in the Evo LTE/One X are faster. They are based on a better and more modern ARM and have more horsepower. Fewer faster cores for single-user, low-threading applications is always much better than more slower cores.
So- the statement Alex said "the Galaxy S III is the fastest Android phone money can buy" (twice) in the review, is not entirely accurate. The SIII's Exynos 4 CPU will be the fastest in some limited situations (with the GPU in more situations), but in more cases, it will be SLOWER than the S4 in the Evo LTE and One X. A perfect case of raw benchmarking designed to show multithreading power will simply not reflect real use situations.
In reality, it probably doesn't really matter. Both are very fast and certainly in the same class. And both are battery friendly.
In any case, the USA version of the GSIII will probably use the same CPU as the Evo LTE/One X... so all of this is moot
Battery:
I suspect the Evo LTE will win. But time will tell. Again, both will be very good. The SIII does have a removable battery, which is nice.
Screen:
Evo LTE wins
Size/Weight/RAM/Storage:
All identical, or very similar.
Camera:
Still a bit early to tell. Probably very similar.
Construction & Design:
I will give both to the Evo LTE. Feels extremely well built. Aluminum case, not white (ug), kickstand, silver bezel. Yum.
OS/UI:
Too soon to tell. Touchwiz really sucks, generally; but Sense seems to still be a bit bloated and the multitasking complications can be irritating. Bugs & updates- HTC historically has done a better job at fixing and pushing faster.
Radios:
Who knows
Memory:
If the articles are right, the USA SIII version will blow away the Evo LTE / One X by offering 2GB of RAM. It is unfortunate HTC didn't think ahead and put at least 1.5 in the EVO LTE. What this means for real-world use is, as of yet, undetermined, however.
Both are killer phones.
