If you are basing your disappointment on Userbench remember that the 1800X benched there seems to be running at 3.65Ghz (why I don't know). The 1800X should be at 3.6 -> 4.0Ghz possibly more with XFR enabled. The Kabylake 7700K on the other hand is running anywhere from stock to 5.15Ghz. So at peak according to Userbench a 5.15Ghz Kabylake 4core 8 thread chip is 35% faster at a 41% higher clockspeed in singlethread work and 30% faster at tasks using 4 threads. This is if the clockspeeds are correct. Not much...

They have a nice writeup on the IPC difference between Kaby Lake and Ryzen:

http://cpu.userbenchmark.com/Faq/How-does-IPC-compare-between-AMDs-Ryzen-and-Intels-Kaby-Lake/108

Conclusion.
Ryzen's IPC could match Kaby Lake but at worst lags by 9%. The big unknown is Ryzen's overclockability as this will determine the actual performance levels delivered. The Kaby Lake 7700K can comfortably hold 4.8 GHz so, under quad core workloads the 1700X would have to overclock to 4.8 GHz or better in order to beat it. On the other hand, on an eight core workload assuming a clock speed of 3.4 GHz (stock) for the 1700X and 4.8 GHz (overclocked) for the 7700K, the 1700X wins by a whopping 41%. Even though these preliminary results are based on a limited number of samples one thing is for sure: Christmas has come early for workstation users who are able to make use of more than four cores simultaneously.
