Ian Cuttress for Anandtech:
Price for Performance is still one of AMD's strong points. For the multitude of tests where that $499 1800X is able to match or beat a $1049 i7-6900K, it directly translates to a 2x in price/performance.
Other processors have a smaller price/performance ratios, but they're still giving Intel a run for its money.
It's good to see competition in the x86 CPU space again. Looking forward to future updates.
