Intel cant get their act together in the Server Market Today because of the absurd ammount of cores that are required to be competitive.
AMD's radical new design approach with Zen and their ability to iterate and refine it so well caught Intel completely off guard. The process issues they had also hindered their ability to compete, but I'm not sure it ultimately would have been able to save them.
Even now that they've made some architectural shifts that will allow them to compete better, they're still having a difficult time of it. Even without v-cache, AMD has still remained competitive with Intel's latest and greatest and there are still a few benchmarks that Intel can't win, even when pushing the power to absurd levels.
But the inclusion of v-cache opens up even more possibilities for AMD and it's built in the same modular fashion that allows them to apply is selectively so that they can use a very limited number of dies to assail Intel's entire product stack and even control areas that Intel has had to essentially abandon.
