Nvidia makes GPUs while other major chip manufacturers make CPUs, which power laptops and phones. But it's only a matter of time before the company attracts serious rivals.
While Nvidia might be the fastest, they are not always the cheapest option, especially if you rent it in the cloud. When I last checked, it was cheaper to rent AMD GPUs

But it is no longer funded by AMD or Intel
AMD GPUs are still supported by frameworks like PyTorch
