Adreno 508 has 96 GPU ALUs at 850 Mhz, Adreno 510 128 ALUs at 600 Mhz. Multiplied clockwise the 508 has a small advantage but maybe it can't keep this higher clock permanently or RAM ist not fast enought so it says 170 GFLOPS for the Adreno 508 vs. 180 GFLOPS for Adreno 510.

I think Qualcomm ist right with the naming 508/510 as practically both GPUs are in same range.

The 650 still has superior single-thread performance as Cortex-A72 is much faster than Cortex-A53 even with lower clock frequency as it has more than 2x integer instructions per MHz compared to Cortex-A53 (4.72 DMIPS vs. 2.24 DMIPS).

Also Snapdragon 630 is 4x 2.2 GHz + 4x 1.8 GHz Cortex-A53 so only the 4 faster Cortex-A53 cores at 2.2 GHz compete against 2 ultra-fast Cortex-A72 cores of the Snapdragon 650 only at 1.8 Ghz working as two big.LITTLE clusters and not as a "real" octacore.

Yes, the Snapdragon 630 is the more modern chip from a newer generation (14nm, DDR4 RAM, LTE Cat 12/13, BT 5.0, USB 3.1) compared to the 3 year old Snapdragon 650 (once called Snapdragon 620 but performance-wise I wouldn't expect more.

But less power consumption for a similar performance seems to be true:

> Battery life
> Xperia XA2 92h endurance rating
> Xperia X 67h endurance rating (2620 mAh)

PS: Sorry, it's mostly only because of battery capacity increase:

> Xperia XA2 Non-removable Li-Ion 3300 mAh battery
> Xperia X Non-removable Li-Ion 2620 mAh battery
