Query Execution Performance 'Stored Procedure' VS 'Query Through SSMS'

Hi,

I had a doubt regarding the Query Performance that may be achieved via Stored Procedures against  Regular SSMS Query.

Suppose I have a simple Select Query that selects data from various tables using various joins.

My question is, would there be a performance difference when i execute the same query via the Store Procedure VS Executing the same query directly via SSMS (SQL Server Management Studio).

I believe that both would yield the same performance, but still would like to confirm this.

Thanks
