Any use cases for RTX PRO 4500?

At its price point, PRO 4500 doesn’t offer as much raw performance due to its lower power draw at 300W. The 5090 can perform up to 60-70% in short spurts with 600W, but can also be undervolted down to 400W.

Are there legitimate reasons other than 24/7 usage and lower power draw for this PRO 4500?

How would this compare to 4x 3090 and 4x R9700? Granted multi card solutions have inefficiencies with large power consumption and needing dedicated boards and PCIE lanes.
