This is a Krait 400 CPU with which you get Adreno 320 graphics. It's paired with 3GB RAM. Other key specs include a massive 6000mAh battery, and a MicroSD slot so you can add up to 64GB of storage. Our 16GB model had 11.2GB available to use out of the box. It all adds up to a beast of a tablet.
Despite the thin and light shell the Xperia Z2 Tablet is a snappy performer. We'll get into synthetic benchmarks in a moment, but the most important thing to say is that you will fi nd the Z2 Tablet fast and responsive. As fast and responsive as any Android device we have used, even when placed under load.
Benchmarks are fun because they give you an idea of where a tablet or smartphone ranks against its rival, but take them with a pinch of salt. They are synthetic test designed to give you a number, not hard-andfast rankings. None the less, the Xperia Z2 Tablet's benchmark performance backs up our subjective experience of a superfast tablet – mostly.
The exception was the SunSpider Javascript test from which we got a decent but not amazing average score of 1099ms. Lower is better in this test which measures your browser's ability to handle Javascript, and the iPad Air blitzes the Xperia Z2 Tablet with a score a little faster than 400ms.
We have to say that we found web browsing on the Xperia Z2 tablet a joyous experience, and only occasionally laggy. But this is one to chalk up to the iPad. We ran a GFXBench test to benchmark graphics performance. In the T-Rex (onscreen) test we got our best ever tablet result of 1,530 frames at 27fps (averaged over three runs).
The Xperia Z2 Tablet will chew up and spit out even the most demanding Android games, and beats out the iPad Air which averaged 1,187 and 21fps. And then there is Geekbench 3. This is a somewhat controversial all-round benchmark as some Android manufacturers have been accused of designing their devices to perform abnormally well in this test. (Allegations they almost all deny, by the way.)
So make of this what you will, but the Xperia Z2 Tablet smashed Geekbench 3 to bits in our tests. It returned an average single-core result of 967, a more important multi-core score of 2719. That's the fastest multi-core result we've ever got from a 10in tablet, comparing well with the iPad Air's 2703 points in multi-core mode; and 1487 points for a single core.
All you can really take from this is the fact that the Xperia Z2 Tablet is a fast and responsive tablet. It really is.
