Well... if the server has it queued up in memory, and you have a 10Tbit link throughout, and there's nothing else using bandwidth, etc etc.
In practice my 2.5 Gbit fiber hardwired to a 10 Gbit router, hardwired to a 1 Gbit PC with plenty of CPU and memory rarely pulls 100 MB/s. That said, on the rare occasion it does (usually from Microsoft or Steam), I wish that I had sorted out a better link from the router to the PC.
And even WiFi 6's relatively high latency still makes for playable VR on a Quest 2. We always have more than we think, but less than we want.
