LOL! I was only asked about
power consumption, in case you did not notice. Therefore I was only asking about power consumption.
Now you are mentioning performance and efficiency. That is different, but if you insist...
As said above I am not going to write a review of each nonsensical stuff that one can find in the internet.
Those figures were obtained after they changed the version of the x264 software that they had been using for years. I find curious that they changed the software to a new version specifically optimized for Intel chips, just when reviewed the new Haswell chip.
I know that even the older 8350 is still faster than the new top-end Haswell 4770k

The 9590 is significantly faster than haswell
The two fair benchmarks given by me use normal software. Fortunately, nobody is benchmarking using software optimized only for AMD, because then we would laugh for weeks.
