The AMD architecture Zen will have up to 32 cores, which are grouped into modules of four pieces, and these modules will be up to 8 pieces.
However, in the patch mentioned processors codenamed Zeppelin, but in earlier leaks processors Zen has appeared under this code name, and presumably it refers to a variety of servers.
In the server segment Zen architecture processors will appear only next year. The company has high hopes for Zen architecture , and if they really get up to 32 cores and will be able to show the performance, then, AMD will have a chance to win a part of the server market.
