what is a typical workload that you speak of, where CPUs are better?

We've been implementing GPU support in Presto/Velox for analytical workloads and I'm yet to see a use case where we wouldn't pull ahead.

The DRAM-VRAM memory bottleneck isn't really a bottleneck on GH/GB platforms (you can pull 400+GB/s across the C2C NVLink), and on NVL8 systems like the typical A100/H100 deployments out there, doing real workloads, where the data is coming over the network links, you're toast without using GPUDirect RDMA.
