The Sony ‘Honami’ has made an appearance on benchmark site, GFXBench. It used to be quite common to see upcoming Sony Xperia devices pop up on numerous benchmark sites prior to release, but Sony has done a good job of limiting this in 2013. The C6903 model number has appeared on the site and is believed to be the European LTE version of ‘Honami’.
A number of specs have been confirmed by the listing including a FHD display, Snapdragon 800 chipset (MSM8974) with Adreno 330 graphics. It also shows the handset running on Android 4.2.2 with the latest firmware build at version number 14.1.G.1.406. The maximum processor clock captured by the benchmark is 2GHz, but is likely to be the same as the Xperia Z Ultra (2.2GHZ) on release.
