1. Not everything needs to be pushed up to the GPU. Some things are better left in RAM. 2. What if you only push indexes or similar up to the GPU, like an AB-tree index? You're keeping all of the 'heavy' stuff down, and only uploading a representation of it, to be later replaced with the actual data. 3. Think compression/decompression done on the GPU directly.
