The Windows Phone has taken a surprising toll over the Android phones and the major difference is of the software
The market at the moment is flooded by a wave of Android flagships all over which feature a revamped version of Qualcomm’s top chipset but when it came to topping the charts of the Basemark X test, it was surprisingly Nokia Lumia 1520 which features a vanilla Snapdragon 800. On second place we have the Samsung Galaxy S5 with a score difference of 6% and we can't say much about the scores given by Xperia Z2 because it has not been tested as of yet.
From the tests conducted on one of the sites the Xperia is merely an inch behind the Galaxy S5 as far as the general benchmarks are concerned and it also appears to be closer in the 3D tests. Similar results are expected to be given by the graphics test, the Basemark X. One thing must be noted here that the Snapdragon 801 used in the Galaxy and Xperia flagships has its Adreno 330 GPU clocked higher than the 800 chipset. In the Galaxy S5, even the CPU is clocked higher. So the only difference we are left behind with is in the software. Android 4.4 supports OpenGL ES 2.0, while Windows Phone uses Direct3D 9_3.
Nokia Lumia Icon is also making use of the same chipset as Lumia 1520 and also sports a similar display so we are expecting the same feats from it. On the other hand, the rumored Lumia 930 is also going to belong to the same base. According to the Basemark X, the Windows Phone has outdone the Android which might appear to be quite surprising.
