Samsung ATIV Tab Review: Qualcomm's First Windows RT Tablet
With better battery life than Surface RT and better performance as well, I have to say that in the ARM camp Qualcomm's APQ8060A is definitely the preferred SoC for Windows RT today. Qualcomm's single threaded performance advantage is obvious in interacting with the ATIV Tab, particularly for any work on the desktop (modern UI remains fairly smooth across all platforms). Application performance and web browsing performance are at worst equal to NVIDIA's Tegra 3, but at best are tangibly better. Intel continues to have the overall performance advantage (not to mention backwards compatibility), but at times Qualcomm remains surprisingly competitive in many of our tests.
Ultimately even Atom isn't quick enough to fulfill the dream of having a tablet that can really replace a modern notebook, and that's where the Windows RT/8 cookie crumbles for now. I suspect that once we get to the next generation of SoCs we'll see a better story from all of the vendors (22nm Atom, Cortex A15 based Wayne, Krait 200/300 from Qualcomm).
The ATIV Tab itself feels fairly well executed. Its performance is snappy (for Windows RT) and unlike my W510 experience, I didn't encounter much instability during my use of the Tab. Battery life is better than any other Windows RT or 8 tablet we've tested thus far. The Samsung/Qualcomm combination excels in video playback battery life in particular, giving us the first 10-inch tablet capable of lasting as long as a modern iPad in our video playback test. Web browsing battery life is also quite competitive, equaling the Clover Trail based Samsung ATIV Smart PC.'
