It's easy to pick up on the negatives of Ryzen--REALLY easy. Where Ryzen thrives is where the masses are less knowledgeable. In some cases, this includes myself. They don't understand threading or encoding or processes. They understand video games and FPS. They don't know what Cinebench or Blender is really doing, but they know what Battlefield and GTA V are. So, when Ryzen falls short in those commonplace scenarios, in a manner the layman can easily understand, that aspect of the arch will stand out to more people.
On top of that, people simply don't get to realize where AMD is coming from. They don't really acknowledge that AMD is putting out its first real desktop chip in about 3 years. They don't get how far AMD was from Intel. Maybe they would understand if they took the analogy of basketball games. For the last few years, AMD has been NBA LIVE, promising, failing, delaying, and canceling, in the hopes of an eventual return to glory. Unlike NBA LIVE, AMD actually took its time off to produce something really strong. They did this with a MUUUUUCH smaller team, and a lot less money, too.
Lastly, no one seems to care that it's been 2 days. They think Zen on March 2 is Zen on December 2. There is no concept of improvements from launch with hardware, even as it's become commonplace with software. They read that there are bizarre problems coming up (SMT, power profiles, memory management, and more), but think those are permanent, or negligible. Why people don't expect a chunk of tweaks to smooth the platform out, I don't understand. Why they want AMD to fail so badly, and have Intel continue its overpriced monopoly on the high-end, I understand even less.
