M40 vs 2080S which is better?

So I found out that a tesla M40 has the same amount of cuda cores as a 2080S but 2080S has tensor cores and is a lot more expensive but M40 is a lot cheaper so which would be the best bang for buck?

Price 2080S: 700$ specs: cuda cores 3072 core clock 1815MHz ram 8GB mem clock 2000 (15.5 GB effective) tensor cores: 384

Price M40: 140$(used) specs: cuda cores 3072 core clock 1110MHz ram: 12GB mem clock 1502 (6GBs effective)

Comparing price I would think for coding rendering and AI M40 would be better if you got 2 but tell me what you guys think
