For GCP, it depends. GCP doesn't have a Nitro competitor, but they offer Tensor Processing Units (TPUs). TPUs are more of a competitor to nVidia chips, but they are still custom silicon in the sense of the GP comment.

GCP, AWS, and Azure seem to all be diverging in their specialization. GCP is focusing more on AI/ML/Big Data offerings while AWS is more security-aware, and Azure is more hybrid-cloud focused.

GCP feels the most R&Dish, with the K8s and ML innovations. AWS seems to just be pushing on every front very well. Azure feels as though it's catching up, but a bit more sales led/engineering later than the others.
