I think the heat dissipation relative to volume of the ISS is way lower than these satellites, yet that already needs sizable thermal radiators to cool: https://physics.stackexchange.com/q/150004

GPUs are also very power hungry, I need about 2 square meter of solar panels on my room to feed a single RTX 5090 during summer. How many do you want to send up in a single satellite?

What about the data link? Real world Starlink speeds are capping around 300 Mbps. I understand that is a shared link with plenty of peers but what is a realistic bandwidth between these satellites and some fixed, earth receiving stations?

Pretty sure the plan is to use Starlinks for Earth communication.
