>>42990741Someanon summed it up here:
https://rentry.org/stablediffgpubuy#fp163000 series cards and above have 1:1 fp16 performance(they are the same)
2000 series have 2:1 fp16 performance, (so they would be twice has fast in fp16 over fp32)
1000 series have 1:64 fp16 performance, (SLOOOOOOOOW)
If you have cards older than this use fp32
