I’ve been following the performance previews of Moto X from various sources, and I think Ars Technica’s is the best preview so far. As Andrew says, the Moto X has got a really great GPU, which literally kills the highly configured S4, and also sports a good CPU, which is ok for the device.
The Moto X’s Adreno 320 GPU stacks up very favorably to the same GPU in the Snapdragon 600 used in the Galaxy S 4—they’re roughly comparable, and I would attribute the small differences seen in the apples-to-apples offscreen tests to software optimizations. Both are slightly faster than the Adreno 320 in the older Snapdragon S4 Pro, and much faster than the Adreno 225 in last year’s Galaxy S III.
Me and some of my friends were pretty much let down by the CPU configuration which came out with Moto X. But looks like the CPU is not bad at all:
At any rate, despite having two fewer cores, the Moto X does fairly well compared to the Galaxy S 4. Its browser benchmark scores in particular may be a sign that Chrome has been optimized specifically for the Moto X, since they’re all as good or better than the S 4s—being owned by Google has to have some benefit for Motorola, right?
The entire stats from the benchmarks are super detailed. You can read more from the source link below.
