Earlier quoted context omitted.
it depends how much you're willing to spend. You can get a H100 (80GB) for around 28-30k$, an A100 (40GB) for around 6-7k$, a 4090 (24GB) for 1.5-2k$. You can build a normal pc with a 4090, otherwise you're in datacenter territory. You can bundle up more GPUs. You can decrease the precision of your models to get them to run on cards with less RAM.
A 4060 Ti with 16GB memory costs around $700-800 over here, can I connect two of these to get 32 GB memory to run the bigger models (13B stock or 30B quantized)?
Alternatively, the 4000 series cards rely on the PCI express lanes for linking, so if you want to get the benefits of linking the 4000 series cards as a consumer you’ll want a Threadripper or even maybe an EPYC CPU/motherboard combo.
