Why, benchmark performances, of course. The latest device to make headlines on the AnTuTu benchmark would be the Sony Xperia SL (also known by its model number LT26ii, or the Xperia S refresh if you prefer, where it seems to have confirmed that a 1.7GHz dual-core processor is located underneath the hood.
The chipset of the Sony Xperia XL has yet to be revealed, although there are strong grounds to lean towards the possibiity of an overclocked Qualcomm S3 Snapdragon MSM8260 chipset that sees action in the Sony Xperia S at the moment. The Xperia SL was powered by the Android 4.0.4 Ice Cream Sandwich operating system when it underwent the AnTuTu benchmark.
