AMD FX did win some benchmarks against i7 2600k
There are a lot of negative sentiment about the AMD FX CPU. Many of us expected a wonder weapon that destroys everything Intel. It didn't happen.
Now, if you look at the benchmarks, the FX did score some points against the core i7 2600k. So, the results are software-compiler dependent.
It will be interesting see some Linux+GCC benchmark results.
