I know this guy has industry insights, but it's got to be a touch embarrassing to write something like this. The S810 in the G Flex 2 and the M9 is underwhelming - not just from a throttling perspective but also efficiency.
The paragraph posted above is especially hilarious now that the S6 is in reviewer's hands and the 7420 looks as promised.
I saw an antutu score on the M9 for 51,727 after the throttling update was pushed. The Zenfone 2 got a score of 50,401 LOL. Qualcomm really screwed their customers with the 810.
