I tried and tested it on my 5700xt,in crystaldiskmark i got (5 repeeated times on 1giB)
Read Write (MB/s)
seq1m 2339 2620
q8t1
seq1m 2205 2190
q1t1
rndq32 41.31 38.77
rnd q1t1 34.70 32.80
To be honest i didn't know what to expect, aside for a very high reading and writing speed. I was a bit disappointed in seeing random reading and writing were so slow, the only use i could think about would be having photosets or things like that over there, and then saving the session on ssd when closing the program, but it is easily solved by using a newer nvme ssd

While it is not a 1:1 comparison there has been a driver for windows that allows the creation of a ram drive from vram for NVIDIA cards.
