fwiw, the "TPU instance " has more than one tpu chip on it.

The architectures are so radically different that I don't think it makes sense to try to compare anything but the whole system performance. Trying to do a 1 to 1 comparison for a core or a chip becomes pretty nebulous because the architectures are radically different.

It has more than the chips, too, since the TPUs can't run a TCP/IP stack, gRPC server, etc.
