Machine Learning is a highly complex domain with professionals relying more on the GPU and CPU when training models, neural networking, and deep learning are concerned. However, 64GB RAM might come in handy if there are several trained models to store and you are also associated with more intricate and complex data sets. While the minimum RAM requirement for entry-level ML mapping and modeling is around 16GB, requirements concerning Data Visualization and Predictive analytics can extrapolate the same up to 64GB.
