Did Ryzen meet the hype train? Maybe not. Is it a failure? No. This isn't just about Intel vs. AMD, it is about picking the right CPU for the job. As we learn more about Zen in general, we are starting to understand its strengths and weaknesses better, and can make an informed choice based on that. I knew when grabbing one as soon as I could on launch, I did not have all the facts, but I was willing to try it out for others with similar compute use cases to mine. I still see it as early days, since AMD haven't really given more than a high level overview of how parts within Zen communicate with each other. It will be down to users and software writers to make the most of it.
Currently if you want more than 6 cores from Intel, you need to splash the cash, go old Xeons, or do what I did with ES Xeons. For applications that can use more cores, a 16 core in one socket part could be very interesting, although software wise it could be a nightmare coordinating between the CCX and chip modules. Problems that don't exist with single socket Xeons.
