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.
How many 4ks at 120hz can it run? Asking for a friend
It should support at least 3. In case you’re seriously asking, TB3 is 40GBps and supports 1 display at 4k@120 with DP 1.4.
4K UHD needs a bandwidth of at least 10.2 Gbps, so this could drive eleven 4K displays
It can be much higher - depends on how much color information you’re sending, and what the refresh rate is.
The DisplayPort spec (which alt mode runs across usbc) covers the streams:

So some number from 3 to 11 apparently.

3x 4K at 144hz, it’s right in the graphic in the article.
