IDK a practical use for a 7-pi cluster, but I will note, for tasks that can be performed within the pi's performance envelope, it's an incredibly power-efficient system. So while in many cases a few raspberry pi may lose on upfront cost, their performance/dollar tends to even out when you start factoring in energy costs.

There's diminishing returns as you start to get towards the upper end of performance though, and IDK how 7 pis at full load compare in W/flop vs a SFF PC. 28 cores @2.4 GHz, 35 W for the pi, vs a new CPU running 8 cores, @4.7 GHz, 120W may be a close race.

There's more nuance than just cores & frequency when it comes to performance in a given task, but the pi is remarkably lean.
