The Asian version of the HTC One M8, however, is hosting a faster, 2.5 GHz Snapdragon 801 MSM8974AC processor - just like the Galaxy S5. The difference in benchmarking scores between the 2.3 GHz US/European version, and the 2.5 GHz Asian one, turns out to be quite significant. AS you can see below, the US/European version of the One M8 scores 29431 points on AnTuTu, while the Asian variation clocks 35964 points on the same test.
That's a 20% boost in overall performance, at least on paper, but it's not the whole story. As you can see from the score on the 3D Mark graphics benchmark, the GPU performance of the 2.5 GHz version of the HTC One M8 currently tops the ranks with 21157 points, beating the former GPU leader Xperia Z1 Compact to the punch. That's not to say that you should strive to import a One M8 from Asia at all costs, as both variants are plenty powerful for any demanding application you might wish to throw at them.
