It is still a little difficult to say because we won't see full, independent third-party reviews until the end of next week.
On price though, the 6c/12t CPUs (or 4c/8t CPUs depending on where you live) are going against the 4c/4t Intel CPUs......
On synthetic benchmarks, and especially for single-core performance, the unlocked 1151's are still expected to be faster than AMDs offering, but because AMD will be so close behind now (a HUGE change from the past), that little bit of difference is not expected to make a significant difference in gaming performance. We'll know for sure next week though.
