Why would you use cloud if you do a lot of training? Quad 2080Ti systems cost ~$7k + electricity. Assuming two such systems are equivalent in speed to 1 TPUv3 (4 chips), owning them would be more cost efficient after 4-5 months of training (depending on your electricity costs). TPUs do have the memory capacity advantage though (over 2080Ti).
