While that is the end result, they are still quite different. The 'rake' task loads resources it needs for all rake tasks, and then it shells out to a separate process. In a Rails app, the rake task starts in the development environment (as that is the default) and shells out to the test environment. This means that you take the hit of loading up the Rails environment twice when you run 'rake spec', whereas 'rspec spec' loads it once, and doesn't load up the other things you need for other rake tasks.
