The torch itself recognises obsolete graphics drivers, so there is no need to restrict older cards.
Requiring graphics memory greater than or equal to 5.5G (that is, 6G or more, but the actual available memory will be 5.98G, etc., so write 5.5G for insurance) will exclude most old cards.
The config directly determines that the CUDA computing power is less than 7.0 and can identify cards that don't support fp16, no need to whitelist them.
