In theory yes but you have to take into account IPC and clock speed as well. From what we know, the ryzen CPUs have an IPC similar to haswell and they don't clock much higher then 4Ghz (mabe 4.2 max?) No way is a 6c/12t ryzen chip going to top a kaby lake i7 running at 4.8ghz. The higher clock speed/IPC of the i7 should also beat out the 8c/16t ryzen chips as well. Keep in mind this is purley for gaming. If i was a content creator i'd be snapping up a ryzen CPU in a heartbeat (and as i'm currently on a 4770k i might go ryzen anyway).
Which means diddly squat when the Ryzen 6C/12T CPUs are being targeted against 4C Intel CPUs.
This is from the Digital Foundry review of the Core i7 7700K:

I know some are trying their best to sell the Core i5 7600K,but in the end even Eurogamer results are showing an overclocked Core i7 3770K holding its own against a higher clockspeed Core i7 7600K,it shows how many are getting obsessed with MOAR MHZ marketing.
6C/12T against an overpriced 4C/4T quad core.
Its going to get even worse with Ryzen 4C/8T CPUs.
I love how everybody ON PURPOSE ignores the Core i5 7400,Core i5 7500 and Core i5 7600 which are all locked and don't boost that high. They seem to just hope nobody notices the leaked pricing showing 4C/8T and 4C Ryzen is against locked 4C and 2C/4T Intel CPUs.
Ryzen 4C/8T against those is going to be very interesting as is Ryzen 4C CPUs against Core i3 CPUs. The MORE MHZ won't save most of the sub £300 Intel range unless AMD gets less than Haswell level IPC in games.
Intel will need to drop pricing.
All this excuse making for the current Intel pricing tiers is only going to mean Intel won't drop prices.
