Each Google K80s is one GPU or 1/2 of a K80 board, so technically you are correct that a Google K80 GPU is half of a K80 board. However, they are offered in passthrough mode and achieve full performance. If you want a whole K80 board, attach 2 K80 GPUs to a single VM. You can have 1, 2, 4 or 8 K80 GPUs attached to each VM in GCP. (I'm one of the GPU product managers at Google Cloud).
- shusson 9y agothanks for the info. On a side note, do you know if GCP will ever support preemptible GPU instances?

- paulsutter 9y agoIt would be polite to indicate that on the price list (understatement). While you're here: the other reason we switched to Hetzner is reliability. Sure we can continue training from the last checkpoint but we still lost half a day on average for the many surprise reboots. We suspect that you've overbooked the GPUs and someone has to lose when too many connect.
- minimaxir 9y agoThe price list indicates that 1 instance is 1/2 a device, and so on: https://cloud.google.com/compute/pricing#gpus https://cloud.google.com/compute/pricing#gpus Although I agree it is somewhat confusing in terms of performance.
