Just finished testing a bit on an Instinct MI100 bare metal server, wanted to purchase some AMD hardware to have the possibility testing more easily locally the needed specific setup, before returning on more powerful cloud servers for real work.
Due even for 6b models 8GB memory is often not enough was interested to the RX 6700 XT as cheapest 12GB VRAM option, but RDNA 3 seems to have introduced some specific Ai acceleration hardware.
Will make a huge difference choosing one or the other?
There’s not much in the way of comparative ML benchmarks out there so hard to say really. There is this test which shows the 7700XT being 300-426% faster than the 6700XT in Stable Diffusion (depending on image size) which is a significant difference.
