You will notice that the second size does NOT fit into GPU ram on this benchmark since we ran it on a GPU that has less memory available than the DATA it is run

You will notice that the second size does NOT fit into GPU ram on this benchmark since we ran it on a GPU that has less memory available than the DATA it is running on. Spark is feeble, perhaps but it is one of the tools being used to feed GPU workloads. Here we have replaced a workload where spark was previously used and now it is faster.
