1) This assumes the Zen leak by Canard PC was legitimate and bases scores off that (see this if you have not already: https://www.reddit.com/r/Amd/comments/5 ... _magazine/)
2) Zen per CES demo will be clocked at 3.6 base and 3.9 turbo, gains of 14.3/11.4% versus the engineering sample (3.15/3.5) however performance doesn't necessarily scale 1:1 with clock speeds so I thought up a worst case to best case range.
The Good: Price. Rumors of two Ryzen SR7 SKUs launching at 350 and 500. I doubt it will be this low since it should give performance similar to the Haswell-E i7 5960X (a 1,000 dollar CPU). Most likely they will be 600 and 700 dollars.
The Bad: Performance and IPC. Ryzen is closer to Haswell-E than Broadwell-E. It is still a wonderful improvement over Bulldozer and its derivatives however not enough to match Broadwell-E. I'm not comparing to Skylake or Kaby Lake as I'm thinking Zen will be more focused on HEDT and server loads than consumer.

The ugly: Skylake-E/EP/EX
I have no doubt Intel has a good stockpile of production Skylake E/EP/EX chips at the ready, only waiting for AMD's move. These chips will surely offer a modest IPC and power efficiency gain over Broadwell-E however Intel will price these more aggressively. If the SR7 flagship is $700, Intel will price the Skylake-E 8 core at $750 and will be seen as a value compared to the Zen because of its noticeable gains in power efficiency, IPC and performance.
I also have no doubt Skylake EP/EX will crush Naples in highly parallel workloads as well as AMD has had little time to work on their implementation of SMT while Intel had well over a decade to do so. Supposedly Naples will have octo-channel memory however I doubt this will be enough to overcome Intel's higher IPC, performance-per-watt and mature SMT methodology.
