Most of it. Base salary caps out at $160k except for NY/SF where it caps out at $180k. Once you get into the higher levels most of your comp is stock, which historically has worked out very well for Amazon employees.
Base salary of $200K or more is definitely achievable for senior (level 5 or higher) engineers at big name companies in SF. I have friends who recently changed jobs so I know this for certain.
That said, the stock offers were excellent as well, sometimes more than salary.
