The radiators are significantly smaller than the PV arrays, but not by a massive ratio; looks like about 1:3.6 based on the published area numbers that I could find.
It looks like the ISS active cooling system has a maximum cooling capacity that could handle the equivalent of a single-digit number of racks (down to 1 for an AI-focused rack).

if you were looking at a 10' tall spider and a 36' tall spider, yes they'd both be big but it'd be fair to say that the 10' one is much smaller....
