I don’t think any genuine questions are ‘too newbie to ask’ around these forums so no worries
Completing the DL course without access to a GPU would not work very well. There is a lot of hands on exercises that are part of the learning process.
Many people go the machine in the cloud route (that is how I have started myself). GCP now gives you 300$ to use over a 12 month period and I think both Kaggle kernels and google colab now let you use a GPU. But probably spinning up your own machine is the preferred option. In that case it is GCP, AWS or providers such as paperspace.
This info might be a bit date - if anyone would be kind enough to share how they went about completing part 1 recently without having access to a GPU on local computer, that would be great
