The T4 is going to be slow but run cool. It only takes 70W as opposed to
RTX-2080Ti's 250-300W envelope. So you could power four of those at the
same load as a single RTX-2080Ti. Each will probably give performance on
the order of 50-60% of an RTX-2080Ti, I'm guessing, perhaps even a little
more for a small system. The power consumption is no small thing,
either--it helps save the planet, but it also helps ensure that the load on
whatever server they're installed in does not get too high. Powering
multiple RTX cards in a server has been a problem. However, the T4's are
going to be $2K a pop--you're buying Tesla.
The new 1660Ti cards are another interesting option, but I haven't tested
them and the price per ns of MD, even the power envelop, looks like it will
merely keep pace with RTX-2080Ti, which is where the best deal for most of
us in a single card remains.
