In terms of performance, which would be better? The price is about the same

With the 2080Tis, I have the overhead of inter gpu communication, and have 44 GB of memory, 17408 cuda cores total, 2176 tensor cores total, 1545 Mhz speed

With the 2 Titans, I dont have as much overhead i suppose, have 48GB, only 9216 cuda cores total, 1152 tensor cores total, 1770 Mhz speed.

​

Which do I go with. Once again, the price is about the same
