When it comes to performance, the R7 1800X, R7 1700X, and R7 1700 all deliver exceptional performance. Not only when you compare against AMD's own FX previous generation CPU's, but against Intel's new Kaby Lake Core i7 7700K and Haswell-E 8C/16T Core i7 5960X. In heavy multi-threaded workloads, the Ryzen processors provide comparable or better performance across the board. In single threaded applications, the boost clock speeds drive performance to comparable levels when the core clock speeds are not too far apart. The Core i7 7700K at 4.9GHz is still going to outperform the R7 1800X at 4GHz single threaded. Where Summit Ridge shines is in that multi-threaded workload environment. Single threaded performance is not bad to say the least, especially when you compare to the FX line up. It's safe to say AMD hit its performance targets.
