With reports that Sony is moving from releasing two flagships each year to just one it's rumoured that the Sony Xperia Z4 won't arrive until the summer, but that seemingly hasn't stopped it getting benchmarked.

A Sony phone packing a Qualcomm MSM8994 processor (aka the octa-core Snapdragon 810) has appeared on Geekbench, and while we can't be certain that it's the Xperia Z4, that's a top end processor which we're expecting Sony will use in its next flagship, so it seems very likely.

We can see from the listing that it's clocked at 1.55GHz, which suggests it was the four slower cores that got benchmarked. There's also 3GB of RAM listed and it's running Android 5.0.2 Lollipop.

Slower than the competition

As for the scores, the Sony Xperia Z4, if that's what this is, achieved a single core score of 1196 and a multi-core score of 3576.

Given that we recently saw a reported Samsung Galaxy S6 prototype achieve a single-core score of 1520 and a multi-core score of 5478 and that even the LG G Flex 2 (which also uses a Snapdragon 810) scored 1292 for single-core and 3604 for multi-core, each seemingly using their slowest cores too, the Xperia Z4's results don't seem all that great.

But benchmarks aren't everything and this presumably isn't a final version of the handset. In fact, if the Xperia Z4 really isn't launching until the summer then Sony has plenty of time to tweak and polish the performance. So let's hope it uses the time wisely.
