I'm doing around 700K - 800K PPD per GPU. Using 4x Tesla P4 on preemptied instances that I am paying out of my pocket (Preemptied instances are pretty cheap). I get roughly 1.2M to 1.8M PPD per day.
Instances are running on Debian Buster on a 30GB HDD.
4vCPU and 8GB of Memory which is sufficient.
Preemptied instance as in the instance will shut down after 24 hours.
