120hz vs 60hz is twice the bandwidth, so more like 3-6. Though iirc (and that’s a big if since I’m not going to look it up right now), there’s a touch of overhead and maybe some reserved bandwidth in the full DP signal, so I’d bet more towards 3. More with compression, but it’s not magic.
So some number from 3 to 11 apparently.
