  No.  FreeRADIUS uses a tiny amount of memory and CPU power.

 My iPhone is more powerful than servers 6 years ago.  Those servers ran RADIUS systems with 10s of 1000's of users.

  See the Wiki.

  Realistically, if you have less than 100K users, any $2K server will be fine.  In fact, it will be idle 75% of the time.

  If you have about a million users, the overall network architecture matters more than individual systems.  Fail-over, HA, etc. are all critical.  RADIUS CPU / memory / disk is less relevant.
