The closest comparison in terms of size would be 1 Volta DGX-1 (8x V100s) compared to 2 TPU modules (8x TPU2 chips).

And for completeness, this is the size of a single V100: https://cdn.arstechnica.net/wp-content/uploads/2017/05/34446...
You can see that 8x V100s are still more computationally dense than 8x TPU2 chips. Density is a very important factor in datacenter design.
