Synthetic benchmarks

The Sony Xperia J is powered by a Qualcomm MSM7227A chipset, which packs a 1GHz ARM Cortex-A5 processor, 512MB of RAM and Adreno 200 GPU. That's one of the lowest-powered still available Qualcomm chipset on the market, but it's quite common within the low-end class.

The CPU performance is quite poor. That also results in a rather choppy UI navigation, which is probably the worst thing about the Xperia J. The Xperia J CPU does better than lower-clocked Cortex-A5 designs, if that's any consolation.

The Adreno 200 GPU is an old design and FWVGA resolution seems to push it a bit too hard. Still, with a NenaMark 2 result of about 20fps, the Xperia J should do okay in casual 3D games, but don't expect the top-shelf titles to work. We actually tried the free game Dead Trigger and it ran well, so the Xperia J will still do the job in most of the games currently available.

Web browsing performance seems to be the problem in the Xperia J though, you can improve it if you use Chrome instead of the stock Android browser (which crashes occasionally when the RAM goes full).

As expected, the Xperia J is hardly a benchmark champion. Its chipset is not even enough to provide a smooth ride through the interface and results in the occasional hiccup. It does okay for non-demanding tasks and things might get better when Jelly Bean comes, however.
