We benchmarked the CPU, math, graphics, and memory performance of the Galaxy Tab 2 7.0 and Nexus 7 using the Android AnTuTu benchmark app. The results, based on AnTuTu version 3, appear in the chart below. Unfortunately, we did not have a Kindle Fire HD available to include in the test.

In conclusion, depending on what’s most important to you, any of these three 7-inch Android tablets could turn out to be the better choice. For example…
- Only the Galaxy Tab 2 7.0 has a backside camera for taking photos
- Only the Kindle Fire HD offers HDMI video output for connection to a TV or monitor
- The Kindle Fire HD has a non-standard Android OS with limited Google services
- The Nexus 7 offers the snappiest performance, thanks to its quad-core CPU
Personally, I prefer the larger size of any of these 10-inch Android tablets to any 7-inch tablet for most purposes. As far as 7-inch tablets go, however, I favor the Nexus 7 based on its high speed quad-core performance, latest Android 4.2 OS, lightest weight, and comfortable nonslippery rear surface. Since most of us have smartphones with decent built-in cameras these days, the Nexus 7’s lack of a rear camera isn’t too serious a deficiency.
