Or, seen another way (better representation of the overall reality): The 7700k is losing in all aspects below w.r.t. the Ryzen 7 1800X, except absolute single-threaded perf. Intel is losing in: - absolute multi-threaded performance - relative multi-threaded performance per $ - memory bandwidth - L3-cache bound workloads (AMD has twice more L3) - price of motherboards

You left out the tiny detail that the 7700k is $150USD cheaper than the 1800X.

  True. But IMHO justified and worth it because AMD beats Intel in all these areas.

  What about when you factor in mobo costs?

I'll have to disagree on a few of the points on that list: > - relative multi-threaded performance per $ Highly depends on the particular workload. Given the few benchmarks we have right now, it seems to go 50-50 once you factor in the lower price of the 7700k. At the very least, this one is close. > - memory bandwidth Seems about equal from the measurements I've seen (the theoretical numbers are irrelevant). > - L3-cache bound workloads (AMD has twice more L3) Cache-size bound workloads to be precise. Cache latency still seems higher, even on L3. Overall, the 1800X seems to make the entire Broadwell-E series redundant on price/performance (at least at current price), no argument there. Against the 7700k, however, it's a very interesting decision, entirely based on the distribution of your workloads. And if Intel drops the prices on Kaby Lake, the value equation can change very quickly indeed.

  Ryzen 7 1800X unambiguously beats the 7700k on memory bandwidth: http://www.guru3d.com/articles_pages/amd_ryzen_7_1800x_processor_review,13.html http://www.guru3d.com/articles_pages/amd_ryzen_7_1800x_proce...

    Guru3D seem to be the only ones to manage memory frequencies over 3 Ghz, most reviewers report a lot of issues with the memory subsystem at the moment. In many reviews (see [1] for a representative example) the 1800X is on par or even slightly behind the 7700k in memory bandwidth, so at the very least the situation is far from unambiguous.
