Sony Xperia Z3 Tablet Compact review

Performance

The Sony Xperia Z3 Tablet Compact has a Snapdragon 801 at its heart - quad-core Krait 400 processor at 2.5GHz and Adreno 330 GPU. Sony has paired that with 3GB of RAM, making this one of the best-spec'd tablets on the market.

There's interesting competition in this size segment though - the Exynos 5420 powered Samsung Galaxy Tab S 8.4 and the Tegra K1 powered Xiaomi Mi 4.

Starting off with CPU benchmarks, the Xperia Z3 Tablet Compact doesn't place very high but neither the Xperia Z2 Tablet nor the Xperia Z Ultra do much better in Geekbench 3. The no-cheat version of Basemark OS II showed no traces of benchmark rigging and gave the Z3 Tablet Compact an average overall score but a good multi-core performance. Also, a Krait 400 beats a Cortex-A15 one on one as both the Xiaomi and Samsung tablets demonstrate.

Adreno 330 is a speedy GPU - other than the NVIDIA-powered Xiaomi Mi Pad, the Xperia Z3 Tablet Compact is one of the top performers. Here the on-screen results are only slightly worse than the standardized 1080p off-screen tests as the Xperia Z3 Tablet Compact's resolution is nearly that - 1,920 x 1,200 pixels. Most other high-end tablets have higher resolution. It's on-screen results that count though and it's clear that Mali-packing Exynos is just no match, even the PowerVR used in the iPad mini 2 and mini 3 doesn't cut it.

The tablet comes with only the Chrome browser, which isn't the fastest on mobile. Other manufacturers typically use customized versions of the stock browser that has been tuned to that particular device, but not Sony.

The Z3 Tablet Compact doesn't do so hot in JavaScript benchmarking (despite its good single-core performance) and only shows an average score in BrowserMark 2.1 (despite the lower resolution).

In conclusion, the Snapdragon 801 chipset (the one with a 2.5GHz processor) offers solid performance for apps. Gaming is some of the best a mainstream tablet has to offer (Xiaomi's market share in the west is still narrow). The web browsing performance is somewhat uninspiring but it's still goof enough.
