If you're one of the people who was worried about how the T-Mobile Galaxy S II would perform compared to the others, you can stop right about now. T-Mobile had to go with a Qualcomm chip instead of the Exynos in order to use the HSPA+42 network, and most just assumed that it wouldn't match up. As you can see, number-wise it sure does.
I'm not much for benchmarks, but if you hit the break and watch the video you'll notice everything is nice and smooth, just like we would want it to be. I'll bet in real world use, you would never be able to tell the difference -- and that's the way it should be. Nice job, Samsung!
