Question Max shared memory for Ryzen 5 8600G IGPU

[Pimpom]

What's the maximum amount of RAM that the Ryzen 5 8600G's IGPU can share from system memory? Does it depend only on the motherboard BIOS setting?

I vaguely recall something like 2GB but I can't find that bit of information anywhere now. Maybe I'm confusing it with something else.
